Yeah, that's revenge. It'll get you out of bed in the morning, and when you get it, it feels great... for about five minutes. I've been there. Me and Sam – we have had our fair share of fights – more than our share – but no matter how bad it got, we always made it right because we're family. I need him. He needs me. And when everything goes to crap, that's all you've got – family. And you might be a-an all-powerful being... but I think you're human where it counts. You simply need your brother.

- Born January 24, 1979; the same month and day as Jess. In an interview Eric Kripke said the reason they share a birthday was "...not a creepy, mythology, conspiracy reason. January 24th is my wife's birthday, and it's kinda my valentine to her."

- Named after his grandmother, Deanna Campbell.
- Drives a black 1967 Chevy Impala which his father gave to him.

- In seasons one and two, Dean alternates between wearing two bracelets. One is an African tribal bracelet and may either be a support bracelet from Invisible Children, or an elephant hair bracelet, which are believed to protect the wearer and bring them good luck and fortune.

Michael's True Vessel
Consent: Yes (escaped before possession could occur, which forced Michael to take Adam instead)
According to Zachariah, Dean is the "Sword of Michael," meaning that Dean is Michael's true vessel. His brother Sam is Lucifer's true vessel. The archangel Gabriel states that the Winchester brothers were always destined to be vessels, partially because of their bloodline, and partially because their relationship parallels that of Michael and Lucifer. Michael himself tells Dean that his line goes all the way back to Cain and Abel, thus explaining why Dean is destined to kill Sam.
Gabriel: Why do you think you two are the vessels? Think about it. Michael, the big brother, loyal to an absent father. And Lucifer, the little brother, rebellious of daddy's plan. You were born to this, boys. It's your destiny. It was always you. As it is in heaven, so it must be on Earth. One brother has to kill the other.
Dean consents to being Michael's vessel in 5.18 Point of No Return; as Michael begins to appear, Dean reneges and kills Zachariah. He tells Sam that he changed his mind because he didn't want to let him down. Their half-brother Adam Milligan is taken as the vessel instead.
March 5th, 1861

April 30-May 2, 1973
A 29 year old Dean is transported back from 2008 by Castiel. He discovers his mother Mary was a hunter, as were her parents. She was very capable but ambivalent about the life; she wanted to leave for a safe life with her boyfriend, a mechanic recently returned from Vietnam – John Winchester. She tells Dean the worst thing she can think of is having her children raised to be hunters. Mary and Samuel (Dean's grandfather) start hunting a demon, which is revealed to be Azazel. Dean goes to Daniel Elkins' house and steals the Colt, with the hope of killing Azazel and thus preventing the tragedies that have cursed his family. When Dean, Samuel and Mary encounter Azazel, he is very interested in Mary, and subsequently possesses her father. He kills both her parents and John, and then offers Mary a deal in return for John's life. Dean is unable to stop the deal, in which Mary agrees Azazel that can have access to her home in ten years time.
Spring or Summer 1978
Dean and Sam are taken back in time from 2010 by Castiel so that they can defend their parents from Anna Milton. Anna has come back in time to kill John and Mary, thereby preventing Sam's birth. Mary remembers Dean from his previous time travel, but John does not. The two are married, and Mary does not want their life interrupted by hunting, something she has left behind. She is persuaded to accept Sam and Dean's help when Anna goes after John, and the family retreats to a safe house. Once there, Dean tells Mary about her future, and reveals his true identity. He tries to warn her about the night in the nursery when she will be killed. Sam suggests that it is not enough for her to avoid the nursery. She must leave John so that Sam and Dean will never be born. Mary informs them that it is already too late: she's pregnant. Anna attacks, but Michael intervenes by using John as a vessel. He destroys Anna, then wipes the memories of John and Mary so that they will continue with their lives as before. He then returns Sam and Dean to the present, assuring Dean that he will one day consent to being a vessel.
January 24, 1979
Dean is born.
The Journal mentions that prior to Mary's death, Dean played t-ball.
November 2, 1983
Mary Winchester is killed by Azazel when she interrupts him feeding demon blood to Sam. John hands the infant Sam to Dean as the nursery burns and tells him to "Take your brother outside as fast as you can! Don’t look back! Now Dean, go!"
John leaves Lawrence with Dean and Sam before Dean's fifth birthday (see The Journal).
When Dean is "6 or 7," John takes Dean out shooting for the first time, using bottles as target practice. According to Dean, he "bullseyed every one of them." (Story told by Dean to Jo in 2.06 No Exit). Dean cites this story as one of the fonder memories of his father.
In 1.18 Something Wicked Dean recounts to Sam of an occasion when John is hunting a shtriga in Wisconsin and leaves Sam and Dean alone in a hotel room. Dean gets bored and goes out, and comes back to find the shtriga attacking Sammy. John returns in time to scare the shtriga off. Dean is haunted by his failure to defend his brother.
In 7.10 Death's Door, Bobby has a flashback to a sunny afternoon in "89-ish," when he took young Dean to a park. Ten-year-old Dean tells him, "Dad says I'm supposed to practice with the double-barrel," but Bobby insists that he gets to throw a ball around "like a regular snot-nosed little jerk."
When Dean is in sixth grade he makes his first sawed-off shotgun.
Christmas Eve 1991
Events told in flashback scenes in 3.08 A Very Supernatural Christmas:
Dean is left to babysit Sam (8 years old) while John is on a hunt, and Sam begins to interrogate Dean about what it is that their dad actually does. Dean responds "You know that. He sells stuff." When Sam moves on to asking about their mother, Dean gets angry and yells "Shut up! Don't you ever talk about mom! Ever!" before storming out. Upon his return, Sam reveals to Dean that he found and read their dad's journal, and demands to know if monsters are real. Dean finally resigns himself to telling Sam the truth.
- Dean: I swear, if you ever tell dad I told you any of this, I will end you.
- Sam: Promise.
- Dean: First thing you have to know is...we have the coolest dad in the world. He's a superhero.
- Sam: He is?
- Dean: Yeah. Monsters are real. Dad fights 'em. He's fighting them right now.
It is hinted at that Dean still believes that his father is a "superhero" at this point, and continually excuses his flaws, while the tension between Sam and John is clearly starting to take root.
Dean is 16.
- Dean: ... So, I picked up this crossbow, and I hit that ugly sucker with a silver-tipped arrow, right in his heart. Sammy's waiting in the car and, uh, me and my Dad take the thing into the woods, burn it to a crisp. I'm sitting there and I'm looking into the fire, I'm thinking to myself... I'm sixteen years old. Kids my age are worried about pimples, prom dates... I'm seeing things they'll never even know. Never even dream of. So right then I just sort of...
- Gordon: Embraced the life?
- Dean: Yeah.
In November 1997, John "parks" the kids in Fairfax, Indiana, where they attend Truman High School. While Sam is having trouble with a bully named Dirk McGregor, Dean gets a girlfriend, Amanda Heckerling; although he becomes uncomfortable when she wants him to meet her parents. When she catches him cheating on her with another girl, she challenges him, charging that his "cool" persona is a cover for his loneliness.
1998 or 1999
Dean is 19 or 20.
In 3.02 The Kids Are Alright, Dean says it has been "8 years ago," then edits himself to say it has been "8, almost 9 years." The episode is based in 2007, therefore, depending on when "8, almost 9 years" ago was precisely, he was either 19 or 20 at the time.
Dean goes on a road trip that was supposed to be "5 states, 5 days" while Sam (15 or 16) was "in Orlando with dad, wrapping up that banshee thing." However, Dean reveals in 3.02 The Kids Are Alright that he spent most of his time in Lisa Braeden's loft. "She was a yoga teacher. It was the bendiest weekend of my life."
Sometime between 2001-2005
During this time, as Dean tells Sam in 1.13 Route 666, he met Cassie Robinson while he and John were in Athens, Ohio for a hunt. She was "finishing up college" (she was therefore approximately 21 or 22) and they "went out for a couple of weeks." Dean was in love with Cassie, who was the first person he'd ever seriously dated (as Sam says "for more than one night") and the first person he'd ever felt that way about. When he found out he was leaving, he told Cassie the 'big family secret' about hunting because, as Dean says in the episode, he "just couldn't lie to [her]." Cassie, however, called him "nuts" and dumped him. This, as Dean also revealed in the episode, really hurt him, and he decided at that point that it was "stupid to get so close" and that he didn't need to open up to anyone.
Note: It is likely that it was around 2003 or 2004, during the "almost two years" that Dean did not speak to Sam, because Sam claimed that Dean hadn't told him anything about it. That means Dean was approximately 24 or 25.
Dean is 26.
In 1.01 Pilot, Sam asks Dean why he didn't go with John when he left to check out the hunt in Jericho. Dean explains that before he showed up in Palo Alto to get Sam from Stanford, Dean was "working [his] own gig... this, uh, voodoo thing down in New Orleans."
Sam asks, "Dad let you go on a hunting trip by yourself?" to which Dean replies, "I'm twenty-six, dude." This implies that before Sam left for college when Dean was 23 (see again Canon Discrepancies: How long did Sam spend at Stanford?), Dean had not gone on a hunting trip by himself. Considering the two men had not spoken in "almost two years," as Dean points out in 1.01 Pilot, it could mean that Dean hadn't hunted alone until he was 24 or 25.
When John Winchester goes missing, Dean goes to Stanford to enlist the help of the brother he hasn't spoken to for a couple of years. After spending an unsuccessful weekend trying to track down John, Sam returns to Stanford, despite Dean's obvious desire for him to stay. Sam's commitment to returning to shaken when his girlfriend, Jessica Moore is killed in the same manner as their mother. Sam joins Dean, and they go on the road with the aim of finding their father and killing monsters along the way. In particular, they are after the demon that killed Jess and Mary Winchester.
In season one, it is obvious that Dean is happy with his life as a hunter, and he tries to draw Sam back into the life: "Saving people; hunting things. The family business." To some extent, Dean sees himself as a soldier, and his father as his commander. Gradually, Sam and Dean become reacquainted with each other after their long separation – and often clash. In 1.06 Skin, the shapeshifter reveals Dean's anger at Sam going to college, while he had to stay and look after their father. He states that he knows eventually everyone will leave him. They clash over Dean's loyalty and obedience to John. In 1.09 Home, Dean first becomes aware of Sam's psychic abilities, when he has a vision of trouble at their old home in Lawrence, Kansas. In 1.10 Asylum while influenced by the spirit of Dr. Ellicott, Sam tries to shoot Dean in a spirit-induced rage over Dean's insistence in obeying John's orders rather than going to California to find their father. In the following episode Sam actually does leave Dean, who insists he and John are both selfish because all they care about is revenge then later who tells Sam he was always proud of how he pursued what he wanted. Sam eventually goes looking for Dean when he can't reach his brother on his cell phone.
In 1.12 Faith, an accident while hunting a rawhead leaves Dean with a fatal heart condition when he is electrocuted, but he is saved by a faith healer whose wife is controlling a reaper. When Dean asks why he was saved, Roy Le Grange says he looked into Dean's heart and saw "A young man with an important purpose. A job to do. And it isn't finished."
In 1.16 Shadow, as they prepare to battle Meg, Sam announces he will return to Stanford after the Yellow-Eyed Demon is killed, to which Dean says he wishes Sam would stay with him and keep hunting, even if they kill the demon that killed their mom, and Jess.
They come closer to this possibility in 1.20 Dead Man's Blood, when John reveals that there is a weapon that can kill the demon: The Colt. The Winchesters manage to acquire it from a group of vampires. The Yellow-Eyed Demon and his "children" Meg and Tom are quick to act, and begin killing John's friends and threatening to kill more until John gives them the Colt. John tries to trick them and is captured. In the season finale, the two Winchester brothers must rescue their father and face the Yellow-Eyed Demon, who possesses John. It is Dean who senses that something is wrong, when his father, uncharacteristically, praises him. Azazel is able to hold the brothers in check with his powers, and begins to torture Dean. The demon taunts him:
- "You know, you fight and you fight for this family, but the truth is they don’t need you. Not like you need them. Sam – he’s clearly John’s favorite. Even when they fight, it’s more concern than he’s ever shown you."
John manages to resurface and hold the demon in check. John pleads with Sam to shoot him with the Colt, but Dean begs him not to. The demon leaves John's body after Sam shoots him in the leg, and the three Winchester men drive towards the hospital. Suddenly the Impala is totaled by a demon driving a big semi-truck.
The season opens with Dean comatose from his injuries. He encounters a reaper, Tessa, who explains that Dean’s choice is either to stay as a disembodied spirit, and become the type of vengeful spirit that he hunts, or leave this world with her. Just as Dean is about to choose, he is returned to his body and healed because John has made a deal with the Yellow-Eyed Demon, trading his life for Dean's. Before he dies, John gives Dean a last, secret command – that he should save Sam, and if he can't save him, he should kill him. Throughout this season Dean struggles with this secret and his grief and guilt over his father's death. As much as he wants to, he has trouble admitting the secret to Sam. He becomes increasingly concerned about Sam's powers as the season progresses, but attempts to be supportive. During Sam's possession later in the season, Dean insists that Sam could not be responsible for the actions attributed to him, because in spite of Dean's own fears he believes in Sam.
Dean's police record begins to be a problem for the brothers this season. Dean is picked up in Baltimore on suspicion of murder, and the national authorities become aware that he is alive. They associate the crimes of the dead shapeshifter who took Dean's form in 1.06 Skin with the living Dean, who is now officially a fugitive. Matters become even more convoluted when Sam and Dean deal with another shapeshifter in 2.12 Nightshifter and end up holding people hostage to find it. In this episode they first become aware of Special Agent Victor Henriksen of the FBI who has been tasked with hunting Dean down. Their notoriety does allow the brothers access to a prison they are investigating in 2.19 Folsom Prison Blues when they allow themselves to be captured. They later escape.
Some of Dean's inner desires are revealed in 2.20 What Is and What Should Never Be, when a djinn attacks Dean. It uses a strong desire from Dean's subconscious (that his mother never died) to hold Dean captive in a dream world. There, Mary is indeed alive, Dean has a girlfriend and a job as a mechanic, but Dean and Sam are not close, and rarely speak. However, when Dean finds out that it is a fantasy and that all the people he has saved are dead in this reality, he struggles to escape it. He decides in favor of his life as a hunter, but he later admits to Sam that "I liked it there. I didn't want to leave."
In the season finale, Sam is kidnapped by the Yellow-Eyed Demon and pitted against the other Special Children. Dean and Bobby arrive as Sam is battling Jake. Jake comes up behind Sam and stabs him in the back with a knife. Sam dies in Dean's arms. Grief stricken, Dean makes a deal with a crossroads demon that echoes what his father did for him - Sam's life for Dean's, and Dean is given one year to live. Dean also agrees not to fight the deal, on pain of Sam's death.
In the climax of the episode, the boys battle the Yellow-Eyed Demon. The Devil's Gate in Wyoming is opened by Jake who using the Colt and demons and souls pour forth – including John. The spirit of John helps fight the demon, who is finally killed by Dean with the Colt. Sam and Dean share a silent moment with John before he disappears. The brothers then move forward with the knowledge that they have one year of Dean's life left.
In the third season premiere 3.01 The Magnificent Seven, Dean decides to make the best of his final year, indulging in many pleasures and refusing to even think about saving himself, while Sam tries desperately to find a loophole in the crossroads demon's deal. While searching for escaped demons to send back to Hell, Sam encounters Ruby, a mysterious blonde who assists him but who also informs him that, for some reason, demons are killing all of his mother's old acquaintances. Sam learns that Ruby is a demon, and she promises him help in freeing Dean from his contract. She "fixes" the Colt so that it can again kill "anything," and also shows them a knife in her possession that can kill demons. Later, they learn from her that all demons used to be human, but had their humanity burned away slowly in the fires of Hell. Dean begins to train Sam to fight demons alone once he is gone.
In 3.10 Dream a Little Dream of Me, Bobby falls into a coma, and Sam and Dean investigate the murder of a scientist. In the course of viewing Dean's dreams, it becomes clear that Dean believes that Sam was their father's favorite, but only thought of Dean as a tool. Dean encounters a future, demonic version of himself in a nightmare, which shocks him into starting to fight for his life and to realize he is not worthless. After waking up, Dean admits to Sam that he doesn't want to die. Meanwhile, Bela steals the Colt, meaning they won't have it to fight with when the hellhounds come for Dean.
In 3.11 Mystery Spot, Sam is forced to relive the same day, a Tuesday, repeatedly. On each new day, Dean dies a different way despite Sam's frantic efforts to save him. Sam realizes that the culprit is the Trickster, a villain from season two. It finally becomes Wednesday, but this time, Dean dies and doesn't come back. Sam spends months trying to hunt down the Trickster, who reveals that he's been trying to get Sam to understand that he and Dean can't keep making sacrifices for each other, and that Dean is going to die no matter what Sam does. The Trickster then sends Sam back to Wednesday, despite Sam failing to learn the Trickster's lesson. He is warned by Ruby that he might not make it back from Hell.
In 3.12 Jus in Bello, the FBI and Agent Henriksen capture Sam and Dean, thanks to a tip from Bela. While Sam and Dean are in jail, a host of demons comes to kill them. Ruby comes to help them, but is furious to learn they have lost the Colt. She says that she knows of a spell that will destroy all the demons nearby, including herself, and that she is willing to die in order to help Sam. However, they will need the heart of a virgin. Sam and the virgin, Nancy, agree to the plan, but Dean refuses to let her die. Dean's plan to exorcise the demons works, but one demon manages to escape and tells Lilith who — taking the form of a little girl, blows the police station up, killing everyone inside. Lilith, it turns out, wants to kill Sam, as she sees him as a rival. According to Azazel's plan, Sam was supposed to lead the demon army, and Ruby was ready to follow Sam. Now, Lilith has become their main enemy.
Dean continues to search for a means to save himself from his fate, but ultimately is told by Ruby that there is no way to get him out of his deal. Shortly before Dean's contract comes due, he learns from Bela that Lilith, the demon pursuing Sam, holds his contract. As the brothers search for Lilith with Bobby's help, Dean begins suffering nightmares and hallucinations of his hellish fate. When Lilith is located, the three head to New Harmony, Indiana, and Dean discovers that he now has the ability to see the faces of demons underneath their human hosts.
As Dean and Sam confront Lilith and her demon forces in a last-ditch effort to protect Sam and save Dean's soul, Ruby appears and the three are chased into a room by a hellhound that has come for Dean. Dean quickly recognizes that Ruby's human host is now possessed by Lilith, not Ruby, but it's too late. The hellhound mauls and kills Dean in a gruesome fashion. Lilith flees, leaving Sam alone with Dean's mutilated corpse. In the last scene of the season, Dean is shown in Hell, suspended in a void by seemingly endless chains and hooks through his flesh, crying out in agony for Sam's help and yelling Sam's name.
The fourth season premiere, 4.01 Lazarus Rising, begins four months after the third season finale. Dean awakes to find himself in a coffin choking he manages to dig himself out and breaks into a nearby gas station where he gets some water, food and cash and a sneak peek of “Busty Asian Beauties.” Before leaving the store, Dean sees the television and radio flicker on, with static, and a powerful whine that shatters all of the glass and hurts Dean's ears. Dean calls Sam, but finds his number disconnected. He calls Bobby, who hangs up on him, so he hot-wires a parked car and goes to Bobby's house. After proving that Dean is really back, he and Bobby track down Sam in a town right near where Dean was buried — he's in a hotel with a girl, but he claims he did nothing to bring Dean back; he's in town because he is searching for a demon. The girl acts puzzled by all of this and leaves, while Dean tells Sam he remembers nothing from Hell. The Winchesters track down whatever force ripped Dean from Hell. By the end of the episode, it is revealed that an angel named Castiel pulled Dean from Hell on God's command; Castiel tells Dean that God has work for him. The girl in Sam's room, it turns out, is Ruby, in a new body, and Sam had lied to Dean when he told him that he didn't know where Ruby was and that he wasn't using his demonic powers. Dean, in turn, was lying to Sam about Hell; in 4.08 Wishful Thinking, Dean confesses that he does remember every second of Hell.
Later, in 4.03 In the Beginning, Dean is transported back in time to Lawrence, Kansas in 1973. There, he meets his father and mother, as well as his grandparents, and learns of a connection between Azazel and Mary, which explains why Mary seemed to recognize the demon hovering over Sam's crib (as seen in 2.21 All Hell Breaks Loose: Part One) and why her ghost apologized to Sam (in 1.09 Home). A causality loop is revealed in that the time-traveling Dean, by trying to stop Azazel in the past and change his future, actually made the demon aware of his family in the first place, setting in motion the events leading to the death of his parents, the corruption of his brother, and the life he tried to change, therefore setting up a predestination paradox. (However, it is implied by Castiel that the events would have happened anyway without him being there as they were already destined.) Upon returning to the present, Dean is informed by Castiel that Sam is "going down a very dark road," and that if Dean doesn't stop him, the angels will.
Dean follows Castiel's directions and encounters Sam using his powers to exorcise a demon, also learning of Ruby's return. He conveys the warning of the angels. After he and Sam stop a rugaru in Missouri, Sam decides to stop using his powers, which seems to satisfy Dean.
In 4.10 Heaven and Hell, Dean reveals to Sam what happened to him in Hell: time flows differently there, so four months on Earth was forty years in Hell. During that time, he was put on the rack and "cut, carved, and torn" apart until there was nothing left of him, only to be made whole again just so the demons could start over on him. Dean reveals that, at the end of every day, the demon Alastair would offer to take him off the rack if Dean would put souls on it and torture them. Dean resisted for thirty years, then gave in and spent ten years torturing people in Hell to escape being tortured himself.
In 4.11 Family Remains, Dean confesses to Sam that he enjoyed torturing souls, as he finally had the chance to dish out the same pain that he'd endured for the past thirty years.
4.13 After School Special included flashbacks of a teenage Dean and a pre-teen Sam while they are going to a high school. In this episode, we learned that Dean was as promiscuous as ever when he was younger. The girl he was currently dating told him that he acted cool when, in reality, he was a little boy who played with people's feelings to make himself feel better. Dean, clearly stung, from then on hated the school.
In 4.15 Death Takes a Holiday, Dean meets up again with the reaper Tessa. She awakens his memories of their previous encounter with a kiss. Dean confesses that there has been a "hole" in him since that time, and realizes that it is related to her. Soon after she is taken by Alastair in his quest to break another seal, that involved killing reapers. The boys ask Pamela Barnes to help them spirit walk and leave their bodies so that they may find the kidnapped reapers. Once they have, they are captured, but Sam is able to break them out and Tessa is able to continue on reaping souls. However before Dean is able to return to his body, Alastair corners him, but he is captured by the angels and Castiel informs Dean that they have won this seal. As he awakes in his body, Pamela is dying from her injuries she obtained during a fight with a demon, while the boys were "out".
In the next episode 4.16 On the Head of a Pin, Dean is pressed into service by the angels, who need him to torture Alastair for information on who is killing angels, since Dean was his "student" in Hell. Dean refuses at first but eventually agrees. However, he only succeeds in getting Alastair to reveal that Dean was the first seal to break, by virtue of giving in and torturing souls in Hell. ("The first seal shall be broken when a righteous man sheds blood in Hell. As he breaks, so shall it break.") The distraction is enough for Alastair to free himself, the Devil's Trap set up by Castiel having been eroded by a leaking pipe. Alastair nearly kills Dean and then comes close to sending Castiel back to Heaven, but Sam, having grown stronger, arrives, and uses his powers to torture Alastair in to revealing he did not know who was killing the angels. Sam killed him shortly after. As Dean recovers in the hospital, Castiel informs him about Uriel's betrayal. Uriel had been killing angels who did not join his cause: to free the angels' "brother" Lucifer from hell, which would start the end of days and destroy humanity whom they despise for being forced to "bow down" to and they believe is the reason God no longer seems to be concerned with them. He also confirms Alastair's claim that Dean was the first seal, but adds that because of this Dean is the only man capable of averting the Apocalypse. However, Dean does not believe he is up to such a task, telling Castiel to find someone else as tears run down his face.
To put Dean back on the right path, Zachariah, Castiel's superior, rewrites Dean and Sam's memories to remove their knowledge of supernatural creatures, making them believe they're average people working regular jobs. He then drops them in a haunted building. The brothers proceed to defeat the spirit that's haunting the building as Dean's boss, Zachariah restores Dean's memories to show him that hunting is in his blood, not simply something he was brought into by his father, and that he has an opportunity to affect the world in ways most humans will never be able to. This renews Dean's resolve.
In 4.20 The Rapture, Dean witnesses as Sam drinks the blood of a demon he is about to kill. Later in the Impala, Sam is waiting for Dean's rebuke. Sam tells him to get over it and Dean yells at him for drinking demon blood, before Sam gets a request from Bobby to head to his house. Once there, Dean and Bobby trick Sam and lock him in the demon-proof panic room for his own safety as he detoxes.
While Sam is going through painful withdrawal symptoms from the demon blood, Dean asks Castiel for help. He takes an oath to serve God and the angels if it would mean that Sam wouldn't have to kill Lilith, to which Castiel says "if that gives you comfort". Sam escapes the panic room after Castiel releases him, and Dean tracks him down to a hotel, despite Sam's efforts to shake him. They argue whether or not Ruby is corrupting him, if he is supposed to stop the apocalypse, and if Sam is turning into a monster. The argument leads to a fight that Sam wins. Dean yells at Sam by saying, "If you walk out that door, don't you ever come back," after which Sam leaves the room.
The angels take Dean to a "safe" room and Zachariah explains that they are preparing for the Apocalypse and will allow the final seal to be broken. They want Sam to kill Lilith as her death will break the final seal holding Lucifer, after which Dean will kill Lucifer and bring paradise on Earth. Dean is shocked and horrified that they would allow the Apocalypse. He asks Castiel for help, together they escape and meet Chuck to see where the final seal will be broken. As Castiel holds back the archangel, he sends Dean to stop Sam from killing Lilith. Ruby shuts the door on Dean as Sam kills Lilith. After the final seal is broken, Sam finds out Ruby has been working with Lilith since the get-go and manipulating him to kill Lilith to break the final seal to release Lucifer. Dean then enters the room and approaches Ruby. Ruby says "It's too late," to which Dean replies "I don't care," and stabs Ruby with her own knife with Sam's help. A portal opens for Lucifer while Dean and Sam can only watch.
The fifth season begins right where season four ends with the portal opening. As Lucifer escapes the brothers are teleported into an airplane by an unknown force. Dean is told by Zachariah that he is the "Sword of Michael," which means the archangel Michael will use his body as a vessel to lead the forces of Heaven, but Dean must consent to this. Dean refuses and Castiel saves him when Zachariah tries to force Dean to agree by harming him and Sam.
Dean and Sam fight the Horseman War in a town where the people think that their neighbors are demons. Dean worries that Sam cannot control his urge to drink demon blood and the brothers agree to go their separate ways because Sam is a liability with his demon blood lust. Castiel finds Dean and they capture the archangel Raphael to ask the location of God.
In the 5.04 The End, he finds himself in 2014, eventually meeting up with his future self, as well as the survivors, and victims of the Croatoan virus. Dean finds out that Sam let Lucifer into his body, and this was the reason the world was in such disarray. Later, the future Dean is killed by Lucifer, while in Sam's body. After being told by his future self to accept Michael into his body. Dean is transported back to his own time, where he comes face to face with Zachariah. He refuses to become Michael's vessel. In the end of the episode the brothers meet back up again, and decide that they should stay together, to "Keep each other human."
In 5.10 Abandon All Hope..., Dean and Sam get the Colt and head off to take on Lucifer alongside Castiel, Ellen and Jo. It is discovered that the Colt cannot kill Lucifer and Ellen and Jo lose their lives in the fight against a group of Hellhounds, which severely damages Dean’s spirits. Dean is further shown to be “broken” in 5.14 My Bloody Valentine when he is unaffected by Famine’s abilities and Famine tells Dean that he wants for nothing because he is “dead inside.” Dean’s so desperate he even begs for help from Heaven.
In 5.16 Dark Side of the Moon, Dean’s further pushed when he receives word from God through Joshua to “back off” and that God is not going to get involved with the fight against Lucifer. When a despondent Castiel returns Dean's amulet to him, deeming it worthless, Dean discards the amulet into the waste bin.
Dean eventually decides that saying “Yes” to Michael is the only he can do as he doesn't believe they can find a way to stop Lucifer and he doesn't believe in Sam himself. However, it is Sam’s faith in his big brother which eventually convinces Dean not to say “Yes” to Michael.
Eventually, Dean discovers that Lucifer can be locked back into Hell using the rings of the Four Horsemen of the Apocalypse but to do so, Sam must say “Yes” and then jump into the pit. Dean is extremely reluctant at first but then realizes that Sam is a lot stronger than he gives him credit for and he allows Sam to make this decision himself.
Sam says “Yes” to Lucifer in Detroit and is seemingly taken over to him. However, Dean has yet to give up on his brother and chases him down to Stull Cemetery to try and talk with Sam. An annoyed Lucifer severely beats him however Dean continues to call out to his brother, eventually causing Sam to regain control enough to pull both himself and Michael into Lucifer's Cage.
With the Apocalypse avoided and both Lucifer and Sam locked away in Hell, a distraught Dean sets about fulfilling the last promise he made to Sam: to live a normal, safe life with Lisa Braeden and to not find a way of bringing Sam back. Lisa comforts Dean and the they seem to have a try at being a normal family, even sitting down to a family dinner, unaware that outside the house, staring in through the window at them, is Sam.
In the first half of the season, Dean is in many ways the center of the action because Sam is soulless. Dean has been living with Lisa and Ben Braeden for a year. He works construction and drives a pick-up truck, having stored the Impala in the garage under a tarp. He embraces domestic life, and when asked about his past, Dean says on one occasion that he was in "pest control." He has nightmares, though, and keeps vigilant: there is holy water and a gun under his bed, and a devil's trap is painted under the rug by the front door. When djinn track him down and poison him in 6.01 Exile on Main St., he is saved at the last minute by Sam, who injects him with the antidote. Dean is shocked to see his brother; he is both puzzled and hurt to learn that Sam has been back almost a year. Sam has been hunting with their Campbell family members, in particular their resurrected grandfather Samuel Campbell.
Dean struggles with balancing his relationship with Lisa and Ben against the need to help his resurrected brother and to hunt. When Sam approaches Dean for help with a shapeshifter infant in 6.02 Two and a Half Men, Dean is hesitant to go, but Lisa tells him that he should. He proves to be a help with the baby, knowing how to put on diapers and get him to sleep. When he returns, Lisa encourages him to return to hunting full time. Dean does, unwrapping the Impala with a flourish and heading off to meet Sam. As he spends more time with his brother, Dean becomes more suspicious of his behavior and motives, but he is distracted in 6.03 The Third Man by Castiel's news of an angelic civil war with the archangel Raphael. There is also the matter of Bobby's deal with Crowley. Dean and Sam travel to Scotland during 6.04 Weekend at Bobby's to help Bobby regain his soul. Dean's fear of air travel made the journey difficult, but he made the trip to help Bobby.
Dean's relationships with Lisa and Ben and his own brother are severely strained in 6.05 Live Free or Twihard, when Dean is attacked by a vampire leader and turned. He goes to Lisa to say goodbye, frightens her, and shoves Ben away roughly when the boy gets too close. Samuel Campbell has a cure for vampirism, but Dean needs the blood of the vampire that turned him, so he goes to the vampire nest and slaughters them all with a machete. While there, he has a vision of the Alpha Vampire and his plan to build a vampire army. He takes the cure and undergoes an agonizing transformation back into a human. During the transformation, he remembers the moment he was turned and realizes in horror that Sam stood by and smiled while it was happening.
Dean avoids speaking with Lisa about what happened, but when they finally do speak in 6.06 You Can't Handle the Truth, Lisa ends their relationship. Left with only Sam and his guilt over endangering and then losing Lisa and Ben, Dean tries to find out what is wrong with Sam and how to fix it. When Veritas declares Sam to be "not human," Dean attacks his brother and knocks him unconscious. He calls Castiel, who diagnoses Sam as soulless. Though Dean distrusts Sam, he still sees him as his brother. He tries to find a way to return Sam's soul, but the answer eludes him, even though he goes so far as to work with Crowley in his search for Purgatory, hoping the demon will return Sam's soul. This hope is lost when Castiel incinerates the demon. Dean becomes increasingly disturbed by RoboSam's behavior and the thought of Sam's soul still in Hell. Finally, in 6.11 Appointment in Samarra Dean gambles with his own life, and then with Death, who wants the brothers to continue investigating the souls.
The second half of the season begins with Sam having regained his soul, and Dean worrying that Sam will remember his time in Hell if he tries to remember too much of the last year. Dean tries to hide the existence of his soulless self from Sam, but his brother finds out, and wants to make amends for what he did. They are soon distracted, though, by the arrival of a new threat: Eve. The mother of all supernatural creatures, she is released from Purgatory in 6.12 Like a Virgin and threatens to overrun the world with monsters. They research her and her possible weaknesses, and follow the trail of destruction she leaves behind. Dean is possessed by one of her new creatures in 6.16 ...And Then There Were None. The angelic civil war is also an obstacle, and sends them into an alternate universe in 6.15 The French Mistake and an alternate timeline in 6.17 My Heart Will Go On.
Dean gets to live out a cowboy fantasy when Castiel sends the brothers to the Old West in 6.18 Frontierland to search for phoenix ashes, Eve's weakness. They manage to get the ashes, and strike out after Eve in 6.19 Mommy Dearest. She has created a town of monsters, and they have little hope, but Dean, having drunk some of the ash, antagonizes Eve into biting him. She dies, but the victory of her death is overshadowed by her announcement that Crowley, who they thought was killed by Castiel, is still alive. Dean defends Castiel against Sam and Bobby's suspicions, but when they discover the angel has been spying on them, even Dean cannot deny that the angel is not being honest with them.
When they finally unravel Crowley's plan to open Purgatory and use its captive souls as a power source, Dean is shocked and horrified to discover that Castiel has been working with Crowley in secret for the last two years. Castiel is adamant that he needs his half of the souls in Purgatory to defeat Raphael, who wants to restart the Apocalypse, but Dean is resolved to stop him and Crowley. Crowley tries to hold Dean off by kidnapping Ben and Lisa. Dean saves them, but Lisa is gravely injured. Castiel, in a last act of friendship, heals Lisa, and at Dean's request erases their memories of Dean.
Dean's path is next blocked by Castiel, who knocks down Sam's wall to hold Dean back. Even so, Dean and Bobby resolve to stop the angel and the demon. They fail, however, and Castiel manages to claim all the souls in Purgatory for himself, and kills Raphael. A weakened Sam tries to kill the angel, but they discover that he is too powerful. Dean is confronted with the loss of someone that he considered a brother, and the terrifying prospect of a new, God-like enemy.
In 7.01 Meet the New Boss, Castiel spares the hunters, but refuses to heal Sam. As Castiel travels the world, wreaking havoc in his attempt to right the wrongs he sees, Dean despairs. He sees chance of stopping the angel, and instead resorts to drinking, focusing on the broken Impala, and worrying about Sam. As Castiel's actions become more erratic, Dean does come up with an option: binding Death, as Lucifer did. Dean, Bobby and Sam succeed in putting a spell on Death, but Castiel undoes it in a moment. Death does agree to assist in reopening Purgatory, but it is up to them to get Castiel to release the souls. Dean refuses to pray for Castiel to come, thinking there is no hope. Instead Sam prays, and eventually Castiel appears. Cas tries to apologize to Dean, but Dean is not forgiving. Cas returns the souls, and survives, but is taken over by Leviathans, which hung on inside him. In 7.02 Hello, Cruel World the leviathans escape in Castiel's body to a reservoir, and let themselves loose on the world. Castiel disappears beneath the water, and Dean finds Castiel's trenchcoat at the shore, and takes it with him.
Dean and Bobby take a disturbed Sam back to Bobby's place, and confront him about the consequences of losing his wall. Sam admits that he is seeing Lucifer, and cannot tell if he is out of Hell, or still there. Dean worries about Sam as he leaves to investigate the first of the known Leviathan killings. When he returns to Bobby's house, he finds Sam missing, and tracks him by his phone GPS. Sam's hallucinations manifested as Dean, and led him to a warehouse as part of an imaginary hunt. Tormented by his visions, Sam nearly shoots the real Dean when he arrives. Dean, with as much calm as he can manage, grabs Sam's injured hand, and uses the pain of it and his own experiences in Hell to convince his brother that this is the real world. When they return to the salvage yard, they find Bobby's house destroyed, and no sign of the hunter. Dean calls Bobby's phone, and leaves him a desperate, near suicidal, message, pleading for him to be alive.
The brothers are attacked by Edgar the Leviathan in the salvage yard, and are so badly injured that they are taken to the Sioux Falls hospital, which is also infested with leviathans. Bobby appears in 7.03 The Girl Next Door, and manages to get Dean, who broke his leg, and Sam away to hide at Rufus's cabin. As they heal, Dean continues to worry about Sam, though his brother insists he is well. When Sam disappears suddenly to investigate a case on his own, Dean follows his trail, and finds out that he was hunting a kitsune named Amy Pond who has been killing criminals. Sam met her when they were kids, before finding out what she was. He leaves her alive now because she was hunting for her sick son. Dean pretends to accept Sam's decision, but secretly goes after Amy and kills her.
In the weeks that follow, Dean's worry over Sam and the Leviathans, and guilt over the Amy situation, overwhelm him. He sinks into alcohol dependency, even drinking on jobs. When Osiris threatens to punish Dean for his past sins in 7.04 Defending Your Life, Dean gives in to judgment to prevent Osiris from revealing Amy's fate. Sam cannot understand, and tries to get Dean to open up, while also attacking Dean's alcohol use. Matters are complicated when two Leviathans masquerade as Sam and Dean in 7.06 Slash Fiction and go on a killing spree in hopes of exposing the brothers. Bobby sends them to Frank Devereaux, who gives them new fake IDs and insists that they hide the Impala, something to which Dean agrees with great reluctance. Sam and Dean are eventually caught by police, and the leviathans come after them. Dean manages to behead them with an axe, but not before the one pretending to be Dean reveals the truth about Amy to Sam.
The brothers separate for a time, but reunite to investigate a series of murders in 7.07 The Mentalists. Dean receives an unexpected message from Ellen through a real medium, encouraging him to talk to Sam about how he feels. Dean obeys, and tells Sam he feels justified in killing Amy, but guilty about lying to Sam. Eventually they move on, and take their annual pilgrimage to Las Vegas, but life takes another odd detour in 7.08 Season Seven, Time for a Wedding! when Becky Rosen kidnaps Sam using a demon love potion. Dean is forced to work with Garth, an unusual hunter, to get his brother back. In spite of his drugged state, Sam is able to help with the case, and Dean admits that Sam does not need him the same way that he used to. Sam suggests that Dean should be relieved, and that now he has a chance to look after himself instead. Dean does not seem comforted by the idea.
Investigating murders in New Jersey during 7.09 How to Win Friends and Influence Monsters, Sam, Dean, and Bobby, run across the trail of the Leviathans again. They are tampering with the food supply through the Biggerson's Restaurant chain, and Dean ends up drugged by a turducken sandwich, which blocks his emotional turmoil. After Dean recovers, they go after the leviathan test facility, but during their escape Bobby is shot in the head by Dick Roman. The boys rush him to the hospital, where an administrator asks Dean about organ donation. Dean is furious to the point of punching a wall. Outside the hospital, he sees Dick Roman. Dean taunts him, and promises vengeance. Bobby awakes briefly, gives the brothers a series of numbers, and dies.
The brothers retreat to Rufus's cabin to mourn. Over the next three weeks, Dean obsesses about the numbers, and agrees to split up with Sam on a case during 7.11 Adventures in Babysitting so that he can talk to Frank Devereaux about them. Dean has been losing track of time, and does not know that he gave Frank the numbers only four days before. Frank has identified them as map coordinates, and the two set up surveillance on the designated area. Dean passes out, and sleeps for thirty-six straight hours. When he wakes, Frank reveals that he lost his whole family to monsters, and advises Dean that he has two options: to quit, or to keep hunting, and smile while he does it. Dean considers Frank's words carefully, then sets out to find a missing Sam with Krissy Chambers. Dean gets similar advice from Eliot Ness in 7.12 Time After Time. Dean has a drunken one night stand with what turns out to be an Amazon in 7.13 The Slice Girls, and the two have a fast growing daughter together, who comes to kill Dean two days later. Dean tries to persuade her that she does not need to be a monster, but she does not relent, and Sam kills her. Dean's drinking slows after this, though he continues to carry Bobby's flask with him.
In 7.14 Plucky Pennywhistle's Magical Menagerie and 7.15 Repo Man, the brothers revisit their pasts, and Sam's condition gets worse. During "Repo Man," Dean gets kidnapped by the former host of a demon they exorcised while searching for Lilith and as a result of allowing the Lucifer hallucination to help him find Dean, allowing it a stronger grip on Sam's mind. By 7.16 Out with the Old he is unable to sleep, and in 7.17 The Born-Again Identity he is institutionalized after being hit by a car. Dean searches for a faith healer, and to his surprise finds an amnesiac Cas serving as one. He takes Cas to Sam with Meg in tow, telling Cas that his brother was hurt by Dean's friend, and that Dean has not been able to forgive him. At the hospital, Cas remembers who he is after fighting a group of demons, and Dean returns his coat. Cas takes on Sam's suffering, and remains at the hospital in a catatonic state watched by Meg.
The brothers reteam with Garth in 7.18 Party On, Garth, and Garth suggests that Bobby may still be with them as a ghost, tied to the flask. The same idea has occurred to the brothers, but both are reluctant to believe it Bobby is shown to be watching over and helping them and they are finally able to see him in 7.19 Of Grave Importance. Dean in particular is bothered by Bobby's presence, worrying that Bobby made the wrong decision in staying behind. Still, they work toward bringing down the leviathans, and manage to steal a tablet that is the Word of God from Dick Roman, and have a prophet named Kevin Tran translates it for them. Uncovering the tablet wakes Castiel, and Dean tries to get him involved in the fight, but Cas is hesitant and damaged and leaves.
The brothers work on a weapon to defeat the Leviathans based on the tablet, and secure blood from the Alpha Vampire, Castiel, and Crowley for it. Bobby meanwhile becomes vengeful, and asks the brothers to burn the flask, and send him away. They agree, and Dean burns it. He then asks Cas to transport him to the Impala, and tries again to get the angel to come with them in the attack on Dick as he is the key to finding the real Dick. Cas is afraid of doing wrong again, but Dean insists that either way he would rather the angel be with him, and forgives him for what he did. Castiel finally agrees and Dean, Sam, Castiel and Meg attack SucroCorp, using Meg and the Impala as a distraction. Dean faces down Dick Roman and finally kills him with Castiel's help, but as a side-effect, Dean and Castiel are sucked into Purgatory with Dick. Once there Castiel disappears on Dean, leaving him surrounded by monsters.
After a year in Purgatory, Dean escapes with the aid of a vampire called Benny Lafitte, who he subsequently restores to life with a ritual, but Castiels fate is initially unknown. Reuniting with Sam and Kevin, Dean learns that Kevin has discovered another Word of God tablet containing a ritual that could seal the Gates of Hell forever, but Kevin flees because he does not trust Dean to keep him safe. Despite this, Kevin and Dean eventually make contact again after Dean saves Kevin from Crowley with the aid of the returned Castiel, Kevin continuing his research under the protection of Garth, who has taken over Bobby's former role as Hunter coordinator. Although Dean and Benny grow more distant after Sam learns of his existence, Dean stands by Benny when another hunter accuses him of murder.
Following a meeting with their temporally time-displaced grandfather, Henry Winchester, Dean and Sam take custody of the archive of the Men of Letters, an organization dedicated to recording the supernatural before their destruction in the 1950s. With the archive resources and Kevin's translation of the tablet, Sam sets out to complete the three trials to seal the Gates of Hell, which include killing a hellhound, delivering an innocent soul (Bobby) from Hell unto to Heaven, and curing a demon. However, Dean stops Sam when he learns that the trials will kill him, shortly before renegade angel Metatron seals off Heaven using spell to banish all the angels from Heaven and leaving Castiel human.
In order to save Sam's life, Dean manages to make contact with a fallen angel who introduces himself as 'Ezekiel', who manages to trick Sam into agreeing to act as his Vessel while in his coma, allowing Ezekiel to heal Sam's injuries and recharge his own 'batteries' from inside Sam. With Castiel reduced to a human state and on the run from the other angels, Dean orders him to stay away so that Ezekiel can focus his energies on healing Sam while Kevin Tran studies the angel tablet to find a means of reversing Metatron's spell. However, things become more dangerous when the fallen angels begin to fight amongst themselves and Abaddon sets out to take over Hell while the Winchesters hold Crowley captive.
When Castiel regains his powers by stealing the Grace of another angel, he learns that Ezekiel is actually the renegade angel Gadreel, who was banished to Heaven's prison for past mistakes. Taking complete control of Sam, Gadreel kills Kevin and flees, forcing Dean, Castiel and Crowley to collaborate to reveal what has happened to Sam so that he can expel Gadreel from him. Disgusted at Dean's lies, Sam loses his trust in his brother, forcing Dean to work with Crowley to find Cain and receive the First Blade and the Mark of Cain, the only weapon capable of killing Abaddon. Dean is able to kill Abaddon, but is killed himself in a later confrontation with Metatron, with the Mark's influence causing him to transform into a Knight.
When season 10 starts, in 10.01 Black, several weeks have gone by. Now transformed into a Knight of Hell, Dean disappears from the Bunker, leaving behind a note for Sam, which says only, "Sammy let me go." While Sam and Castiel try to figure out what happened and where he is, Dean is busy hanging out with Crowley at bars, singing karaoke, sleeping with women, and getting drunk. He also kills several demons who had been Abaddon supporters. When Sam gets captured by Cole Trenton, and Cole tries to use Sam to lure Dean, Dean makes it clear that he does not care what happens to Sam, and that he will not be coming to Sam's rescue.
In 10.02 Reichenbach, Crowley (thinking Dean would make a good partner in running Hell) convinces Dean to agree to kill a human for the client of one of his crossroads deals. However, when Dean instead kills the client, Crowley realizes that Dean is out of his control. Crowley then finds Sam, and gives him Dean's location. Sam finds him, and reminds him that they know how to cure demons. Dean, however, says that if he had wanted to be cured, he would not have left. Sam doesn't give up and tries to persuade Dean to let him attempt the cure, but Dean mocks him. As Sam pulls out the handcuffs, tear gas is thrown through the window, interrupting them. While Sam is on the ground outside coughing, Dean fights Cole. He defeats him easily, but leaves him alive in order to make him have to live with his failure. Sam takes advantage of Dean's distraction by throwing holy water on him. As Dean falls to the ground in pain, Sam is able to put the binding handcuffs on him.
By 10.03 Soul Survivor, they have returned to the Bunker, where Sam has handcuffed Dean to a chair inside a Devil's trap in the dungeon. Sam begins injecting Dean with purified human blood, which Dean reacts to with great pain. Throughout the process, he continues to taunt Sam mercilessly. Sam perseveres, despite not knowing if the cure is working or not. Eventually, the human blood makes Dean human enough to be able to slip out of the handcuffs and the devil's trap, and he chases Sam through the Bunker, trying to kill him with a hammer. He almost succeeds, but at the last minute, Castiel finally arrives, and is able to stop and subdue Dean. They return him to the dungeon, where they are able to finish the cure successfully. Although Dean is human once again, they know that because the Mark is still there, it will continue to be a problem.
While Dean no longer has access to the First Blade, he still finds himself struggling against the Mark's influence. In 10.06 Ask Jeeves, he kills a shapeshifter, and then proceeds to shoot it several more times after it is already dead. In 10.09 The Things We Left Behind, he has a nightmare in which he is kneeling on the floor in a room full of bodies, covered in blood with a knife in his hand. It turns out to be prophetic - the nightmare becomes reality when loses control and single-handedly kills several men after they attack him. When a shocked and horrified Sam says, "Tell me you had to do this," Dean can only reply, "I didn't mean to."
In 10.10 The Hunter Games, Castiel brings Metatron to the Bunker so they can question him about the Mark of Cain. When Castiel and Sam are elsewhere in the Bunker, Dean locks himself in the dungeon with Metatron and begins torturing him with an angel blade to force information out of him. When the others realize what is happening, they run to the dungeon, and Castiel breaks the door down. Sam pulls Dean away from Metatron, who warns Dean that he is only going to get worse. Dean later admits, "I was going to kill him, and I couldn't stop myself." When Castiel asks him to go talk to Claire, he is ambushed and almost kills his attackers, but manages to resist.
Charlie returns in 10.11 There's No Place Like Home, and she explains to them that she has been split into two - good Charlie and bad Charlie. They are connected, if one Charlie gets hurt, the other one will also get hurt. When Dark Charlie confronts Dean, a fight ensues, and Dean breaks her arm. He continues to beat her until she is semi-conscious, until Sam, carrying Good Charlie in his arms, yells at Dean to stop. Dean, snapping back to his senses, realizes what he is doing and steps back. He watches as the two Charlies merge back into one, his face etched with remorse. Back at the Bunker, a battered Charlie tells him that she forgives him, even though he doesn't forgive himself.
After a spell reverts Dean's body into that of his 14-year-old self in 10.12 About a Boy, he discovers that the spell also removed the Mark. For this reason, he briefly considers remaining as a teenager, but ultimately changes back in order to save Sam, Tina, and himself. After working a case involving a ghost in 10.13 Halt and Catch Fire, Dean tells Sam that he's done trying to find a cure for the Mark of Cain. He doesn't believe there is one, and he can't continue to rely on false hope. He vows to continue to fight and work cases, saying that is where he finds his peace.
When Cain resurfaces and starts killing humans in 10.14 The Executioner's Song, Dean resigns himself to confronting and killing him. Sam, Castiel, and Crowley lure Cain into a Devil's trap in a barn, and Crowley hands the First Blade over to Dean, who takes it with apprehension. While the others wait downstairs, Dean goes up to face Cain, and they fight. Because Dean is desperate to not fully give in to the powers or influence of the Mark, he is easily overpowered, and Cain gains the upper hand. He tells Dean that their stories are very similar, and by killing him he would be doing Dean a favor. If he let Dean live, he would inevitably end up killing those he cares about - Crowley first, then Castiel, and then Sam. The act of killing his brother would be the one he would not survive. When Cain goes to kill Dean, Dean manages to grab a knife from Cain's belt, and uses it to cut Cain's hand off. In control of the Blade once more, he desperately asks Cain to tell him that he will stop killing people - or that he even can stop. When Cain refuses, Dean kills him, devastation written all over him. When he meets up with the others, he gives the Blade over to Castiel instead of Crowley, and then collapses into Sam's arms.
Dean goes to a bar in 10.17 Inside Man and is attacked with a spell by Rowena, who is shocked when he survives, completely unaffected. Dean corners her, and she tells him that he is a bad influence on her son - Crowley. Later, he meets up with Crowley and they have drinks and talk about how they have changed, and what family means.
In 10.18 Book of the Damned, Sam and Dean get a phone call from Charlie. She has managed to find a book called the Book of the Damned that might contain a cure for the Mark of Cain, but is being chased by several men who are able to track the book. They meet up at an old hunting cabin, and when Charlie hands Dean the book, he becomes entranced by it. Unnerved, he hands it back, saying that he doesn't think it's a good idea for him to touch it. After some research, Dean discovers that the men who are after Charlie are members of the Styne Family, who have used the Book in the past for evil purposes. He decides that using the book is a bad idea. He tells Sam and Charlie that the book is calling out to him, telling him to use it, but not for good. He insists that they destroy it, but Sam argues that it is their only hope to save Dean, and he'll do anything he can to do so. Dean goes to a convenience store to get some snacks, and while there runs into Jacob Styne and another man. They attack Dean, but not before telling him that the Book does in fact contain a cure for the Mark. Dean escapes after shooting one of them to death, unloading an entire clip to do so. He goes back to the cabin, giving a few seconds warning to Sam and Charlie. He tells Sam to burn the book, and as the Stynes break into the cabin and attack, he watches as Sam throws a book on the fire that he believes to be the Book of the Damned.
In 10.19 The Werther Project, Sam starts to work with Rowena without Dean's knowledge, and sets out to look for a codex which allow them to translate the Book of the Damned that he was supposed to have burned. When he goes to look for it, Dean catches up with him, and says he wants to help with the case. Sam agrees, though he doesn't tell him what they are really looking for. Sam finds the box containing the codex in the basement of a house, but when he tries to open it, he releases a deadly spell that was put there by Cuthbert Sinclair of the Men of Letters. The spell, which makes people hallucinate and drives them to suicide, makes Dean hallucinate that he is back in Purgatory with Benny. There, Benny tells him that he would be doing Sam and Castiel a favor by killing himself. Dean knows that this is not the real Benny, and says that although he would do it if he really had to, the Mark won't let him die. He wakes up from his hallucination in time to save Sam, who was also hallucinating and on the verge of death.
After investigating a murder in 10.21 Dark Dynasty that they find out was committed by one of the Stynes. When Dean is attacked by Eldon Styne and another man, he is able to defeat them and brings Eldon back to the Bunker's dungeon. While Sam is out of the room, Eldon tells Dean that the Book is protected by magic and cannot be destroyed. When he confronts Sam about this, they get a panicked phone call from Charlie, who has been working on translating the Book of the Damned. She is trapped in a motel bathroom, and Eldon Styne, who had escaped from the Bunker by ripping his arm off, is attempting to break in. Dean, realizing the extent of Sam's secret campaign to save him, angrily criticizes him for lying, and getting Castiel and Charlie involved. They arrive at the motel to find Charlie's body, dead in the bathtub. This causes something inside of Dean to snap. In 10.22 The Prisoner, after telling Sam that he should have been the one to die instead of Charlie, he goes on a hunt for the Stynes. He goes to the Styne estate in Louisiana, where he single-handedly kills at least 15 people. Then he returns to the Bunker, where three more Stynes are stealing things and ransacking the place. He kills them all, including a teenager who pleaded with Dean not to kill him, trying to explain that he was nothing like the rest of his family. When Castiel arrives, a confrontation ensues, ending with Dean severely beating Castiel and nearly killing him. As Dean leaves, covered in blood, he warns Castiel to stay away from him.
Dean wakes up on a motel room floor in 10.23 Brother's Keeper, looking awful as he takes a swig of beer and tells himself, "I'm good." He tries to work a case, but ends up getting another hunter, Rudy, killed. When he goes back to his motel room, he sees the images of both Rudy and Castiel in the mirror. He then proceeds to thoroughly trash the motel room. He goes to an abandoned Mexican restaurant where he summons Death, who he asks to kill him. Death tells him that he can't - the Mark won't let Dean die. Although Death could remove the Mark, he won't, because the Mark acts as a lock which holds back the Darkness, an evil primal force that God himself banished. However, Death offers Dean an alternative - he will take Dean somewhere where he can't hurt anyone. Dean calls Sam and tells him it's time to say goodbye. Sam rushes to the restaurant, where he is shocked to see Death. Sam tries to reason with Dean, telling him that he doesn't need to die, but Dean says that it isn't his death that is the way out, it's Sam's. They fight, and Dean wins. Defeated, Sam finally agrees that Dean must be stopped, and is willing to die in order for that to happen. Death hands Dean his scythe, and Dean tells Sam to close his eyes. Before Sam does, though, he pulls out a few old photos of Dean and Mary, and Dean and Sam when they were kids. He tells Dean to let them be his guide when he finally finds his way back - to remember what it was like to to be good, to love, and to be loved. Sam closes his eyes, and Dean swings, but goes over Sam's head and kills Death instead. He helps Sam up, and as they prepare to leave, a lightning bolt strikes Dean's arm, removing the Mark. Just as they get outside, multiple lightning bolts hit the ground, and columns of black smoke emerge from the holes in the ground and start moving toward them at a breakneck pace. Sam and Dean try to drive away but reverse into a pothole. Trapped, they watch as The Darkness engulfs them.
In 11.01 Out of the Darkness, Into the Fire as the black, swirling cloud surrounds the Impala, Dean vanishes and reappears next to an unfamiliar woman - the Darkness. She thanks him for setting him free, and tells him that they will not harm each other. She reveals the Mark of Cain on her collarbone and informs him that they are bound, and they will always help each other. The next thing Dean knows, he is waking up in a deserted field, where Sam finds him. They head to the nearest town and find that there are dead bodies everywhere, and that there is something that appears to be infecting people, turning them into rabids. They meet up with Deputy Jenna Nickerson and head to the local hospital, where they find more rabids. They also find a man and his newborn daughter. Unfortunately, he has been infected, so he turns the baby over to Jenna. While they are in the hospital, the building becomes surrounded by rabids. In order to get Jenna and the baby out to safety, Sam uses himself as a decoy to draw the rabids away from the others. Just before Dean, Jenna, and the baby reach the building's exit, they run into the baby's father, who tells them, just before he dies, that the child's name is Amara. Dean takes Jenna and Amara to Jenna's grandmother's house.
In 11.02 Form and Void, Dean is heading back to the hospital, when he gets a worried phone call from Jenna, who tells him about the strange things that Amara appears to be able to do. He turns the car around and goes back to find Crowley there, posing as a Catholic priest. Dean and Crowley go outside to talk and return to find that Jenna has killed her grandmother. Dean goes to check on Amara, and realizes that she has the Mark of Cain on her collarbone, in the same spot that the Darkness had it. Dean begins to suspect that she is the Darkness. When Dean asks Jenna why she killed her grandmother, Crowley says that it's because she does not have a soul - Amara consumed it. While Dean and Crowley are distracted, Amara mysteriously disappears.
Sam and Dean start to look for information about the Darkness in 11.03 The Bad Seed, and for any leads on Amara's whereabouts. They also track down Rowena, in order to force her to remove the attack dog spell she had placed on Castiel. In 11.04 Baby, Dean learns about the visions Sam has been having, and that Sam thinks that they are from God. Sam also confesses to Dean that he had been infected by a rabid at the hospital, before he was able to find a cure.
While investigating what appears to be a ghost case in 11.05 Thin Lizzie, Dean interrogates Lizzie Borden superfan Len Fletcher. Through talking to him, Dean realizes that Amara had been in town, and had consumed Len's soul, along with those of several other people. Even more surprising to Dean is the news that Amara is no longer a baby - she is now a 12 year old girl. Sam and Dean continue to look for her in 11.06 Our Little World, trying to find more people who have had their souls removed in order to track her. After Len turns up dead, they figure out that demons are also going after the soulless people. They find another soulless person, Goldie, who has just been arrested, and set up a devil's trap in her jail cell. When a demon arrives, saying he must clean up the messes that were made by his boss's daughter, he tries to kill Goldie, but is stopped by the devil's trap. Through interrogating the demon, Dean realizes that Crowley has Amara. Sam is able to pinpoint a location that is likely to be where Crowley and Amara are, and after some debate, they decide to go there to kill her, despite not knowing how strong her powers are, her weaknesses, or if she can be killed. When they arrive, they are able to enter the building (an abandoned asylum) with ease, but run into several demons inside and get separated. Dean finds Amara's room and goes in to find her (now a teenager) waiting for him. Dean apologizes for what he is about to do, but before he can do anything, Crowley emerges from behind Dean and pins him against the wall. He makes the decision to kill Dean, but as he says this aloud, Amara hits Crowley over the head with a heavy object, and then uses her powers to force him to drop the knife and pin him to the wall. She threatens Crowley and demands that Dean be allowed safe passage out. Then she orders him to leave her room. When they are alone, Dean approaches Amara with Ruby's knife, but she scoffs at him. He can't take his eyes off of her and stares at her in a trancelike state as she reveals that she is God's sister. She tells him that he was the first thing she had seen of God's creation after her release, and that he represents that creation to her. She says that soon she will be ready to settle a score - the oldest score. Dean can't seem to move, until Sam bursts in, which seems to break the trance. As Amara throws Sam back into the hall, Dean charges at her, but she hurls him back. He falls to the floor, and watches her leave.
In 11.07 Plush, Sam tells Dean that the visions he has been having are about Hell, and Lucifer's Cage. He doesn't know if the visions are from God, and he doesn't know what to do about them. When he wonders aloud if it means that he has to go back there, Dean says no, and that it's not going to happen. Sam brings it up again in 11.08 Just My Imagination, but Dean refuses to go along with it, saying that there is always another way. Sam asks what that other way is, but Dean doesn't have an answer.
They continue to argue about it in 11.09 O Brother, Where Art Thou?, when Dean finally agrees to try and find out if it's even theoretically possible to safely talk to Lucifer without opening the cage. When they ask Crowley, he tells them that there might be a way. He captures Rowena and they convince her to help them. Sam stays with Rowena while Dean goes to investigate a massacre at a church. He tells Sam over the phone that he suspects that Amara was behind it. Sam gives Dean updates on the research to find a way to contact Lucifer, and Dean tells Sam not to do anything without him there. As Dean leaves the church, a strange sensation comes over him, and the sounds around him become muffled. He looks around but doesn't see anything, so he goes to a park. Sam calls him and he is about to answer, when the sensation happens again. This time, he turns around to find an adult Amara standing behind him. She touches him on the shoulder, and transports him to a remote wetland. There, she tells him that the things she has been doing has been to get God's attention. She says that she only has a bad reputation because God was afraid that she would make a better creation than his, and that was why she was exiled. Dean asks her what she wants, what her plan is. She replies that she was the beginning, and she will be the end. She will be all that there is. When Dean compares her with God, she says no - he is the Light, and she is the Dark. Dean then tries to stab her, but the knife's blade shatters instead. She tells Dean that she can't be resisted, and moves forward, her hands cradling his face. She opens her mouth as if to suck out his soul, and Dean just watches, once again in a trancelike state. After a few seconds, she either changes her mind, or is unable to consume his soul, and kisses him instead. After the kiss, he pulls back, confused and slightly alarmed. Amara tells him that is the future, that he is the one who set her free, and they are bonded. Dean protests, saying that it was an accident, but Amara insists that it was destiny. He had the Mark of Cain, and she is the original Mark. She tells him that they will be together, that they will become one. A horrified Dean tells her that that is not going to happen. Several angels arrive then, and tell Amara that she must surrender to Heaven. If she resists, every angel will smite her in a single, unified blow. Dean tries to dissuade them, due to the fact that a lot of people would die, but they do not care. Amara kills the angels, and as the skies darken with the impending wrath of the angels, she transports him back to the park, to safety.
Dean's weapon of choice is a stainless and custom engraved .45 caliber Colt MK IV Series 80 1911 pistol with ivory grips, which John is also seen using in a flashback. Dean also uses a Baikal sawed-off, double barrel, break action shotgun when he needs extra firepower. He has also been seen with a H&K G3SG/1 rifle in 2.05 Simon Said. Other small arms used by Dean include a Taurus PT99, a Beretta 92FS, a Smith and Wesson 5906 9x19mm pistol, a Remington 870 12 gauge shotgun and an Ithaca 37 12 gauge shotgun. Dean is shown to possess a large machete in 1.20 Dead Man's Blood, and has used a knife in several episodes. Dean has also wielded a Desert Eagle loaded with wrought iron bullets in 1.18 Something Wicked and tasers which he and Sam used in the start of 1.12 Faith, when he electrocuted himself. Dean, along with Sam, John and others, has wielded the Colt, a specially crafted Colt-Patterson model 1836 revolver made by Samuel Colt himself which, with Colt's special bullets, can supposedly kill anything in creation. However, Lucifer mentions that he is one of five things that the Colt cannot kill, it is unknown if the four other entities Lucifer was referring to were God and the three other Archangels (Michael, Gabriel and Raphael) or the Four Horsemen. As with any professional hunter, Dean relies on salt, pure iron and exorcisms to further combat supernatural forces. When firearms and blades are scarce and Dean is in a dangerous situation, he uses a brawling style of hand-to-hand combat or improvised weapons from the surrounding area. During 4.16 On the Head of a Pin, Dean is shown with a number of torture implements, including syringes of holy water, although he does not like to resort to these measure unless he has no other choice.
- In one version of the pilot script Sam suspected Dean of being a serial killer and the murderer of their father.S1Com, p. 14
- On the map of Winchester, UK, you can clearly see a place named Dean above it, spelling out Dean Winchester.
- Series creator Erik Kripke has said that Sam and Dean's names were a reference to Jack Kerouac's American novel On the Road, whose main characters are named Dean and Sal. Sal was changed to "Sam" because, according to Kripke, the name "Sal" is "inappropriate for a main character."
- Kripke has also stated that Star Wars was the major influence on the series, comparing Dean's character to Han Solo and Sam's to Luke Skywalker.
