===Weaknesses===

Walking down a wooded area, Jack begins hitting himself in frustration for all the people he couldn't save when he is met by his father, Lucifer. Jack is surprised to see his father alive. Lucifer tells him that Sam lied about his death, but tells him not to hold a grudge considering what he has done to Sam in the past. The two begin talking, and Lucifer tells him that no matter how many times they help people, something always goes wrong, and it's neither his fault nor theirs. When he suggests they go off and see the universe together, Jack is excited by the prospect, having become a fan of ''Star Wars'' in his short time on Earth. But before they depart he has Lucifer promise to do something for him, and the two teleport to the Bunker, where they are met by Mary and Bobby. Jack tells Mary they are there to help and asks Lucifer to resurrect Maggie; a hesitant Lucifer obliges Jack, and the two teleport away after Maggie is brought back to life.

Later that night, Jack and Lucifer are watching the stars as they ready to depart the Earth, when Jack begins to hear a prayer from Sam, begging for help. He quickly teleports to the Bunker where he finds Michael attempting to strangle Dean to death, and uses his powers to cause great damage to Michael's vessel. When the pain causes Michael to reveal his partnership with Lucifer, Sam also reveals that it was Lucifer who killed Maggie. As Lucifer denies the allegations, Jack uses his powers to compel Lucifer to tell the truth, at which point he gleefully describes how he murdered Maggie in detail. Learning this, Jack rejects his father, calling him a monster, which greatly angers Lucifer. Realizing he has lost his son, Lucifer tells him he only needs his power, and slices Jack's neck and consumes most of his grace. As he begins to teleport away with Jack, Sam grabs on to him and is taken along to a church.

In the church, Lucifer begins to kill Sam, but Jack tries to stop him, prompting Lucifer to punch him repeatedly. He then coldly tells Jack that he lost his chance of being his son and can always make more kids. Lucifer offers the duo an ultimatum: He will allow Jack or Sam to walk out of the church, and give them a week to stop him, if they fight to the death now. He tosses the archangel blade on the ground between them, and when Sam picks it up and tells Jack to kill him, Jack refuses, telling Sam he won't be able to stop Lucifer, but he believes that Sam will. Telling Sam he loves him and all of them, Jack takes the archangel blade and begins to slowly push it into his chest. Before he can complete the task, Dean arrives, having given consent to Michael to possess him. He and Lucifer engage in battle in the church as Sam and Jack look on. When Lucifer gains the upper hand, Sam throws Dean the archangel blade, allowing him to stab Lucifer in the heart and finally kill him. Sam, Dean, and Jack celebrate their victory, but the celebration is cut short. Jack can only look on helplessly with Sam as Michael reneges on his deal with Dean and takes control of his body before teleporting away, leaving them in the church with Lucifer's corpse and wings burned onto the ground.

In the aftermath of the hunt, Dean congratulates Jack on his good work and agrees that Jack can begin hunting with them again. Having continued to display his strange cough while working with Dean, Jack coughs up blood in front of a worried Dean before suddenly passing out, bleeding from the nose and mouth.

===[[14.07 Unhuman Nature]]===

:''"What I do know is I'm done being special. Before my life is over, I wanna live it. I-I just want a chance to... get a tan... to see a hockey game... get a parking ticket... get bored... and when it's all over... die."''

With Jack's condition worsening and [[Castiel]] unable to heal him, the Winchesters and Castiel quickly rush Jack to a hospital where he undergoes a battery of tests. The doctors are unable to determine exactly what is wrong with him, but learn that he's going into systemic organ failure.

With the doctors unable to help, the three check Jack out of the hospital and bring him back to [[the Bunker]] where they call upon [[Rowena]] for help. After learning that Jack is [[Lucifer]]'s son, Rowena initially refuses until Jack appears personally to try to convince her. After Jack practically collapses in front of her, Rowena agrees to help and runs a diagnostic spell on Jack. From the spell's results, Rowena determines that without his [[grace]] to maintain a balance, Jack's human and angel halves are attacking each other. As a result, Jack is dying and his only hope is to get [[archangel]] grace to replenish Jack's depleted grace.

===[[14.08 Byzantium]]===

:''"He and - and Sam and Dean... they tried their best. But things didn't go as planned. That's why I had to see if you were okay."''

A weak Jack tries to comfort Sam, Dean, and [[Castiel]] as his end nears, but Dean is unable to stand seeing Jack in such a state and leaves the room. Jack asks Sam to relay a message to Dean for him and dies moments before Dean and Castiel reenter the room. Grief-stricken, the three decide to give Jack a [[hunter's funeral pyre]] the next morning and spend the night drinking and sharing stories, essentially holding a wake for Jack.

Jack ends up in a [[Heaven]] where he re-experiences the road trip to Dodge City. However, Jack notices the sun and Dean flickering and leaves his Heaven, where he is attacked by [[Cosmic Entity|a dark force]]. Jack manages to escape and locates [[Kelly Kline|his mother's]] Heaven. Jack is reunited with Kelly and the two begin to catch up when Jack notices someone approaching the house. To Jack's surprise, its Castiel, who offers Jack a way to bring him back that would require Jack to sacrifice a piece of his [[soul]]. As Castiel explains the threat from the Cosmic Entity, it arrives, possessing [[Dumah]], and attempts to drag Jack to [[the Empty]] due to his half-angel nature. With the others ready to perform the spell, Castiel offers a deal to trade himself for Jack which the entity accepts, though it decides to wait until Castiel is truly happy to collect.

Using Jack's blood for a spell to resurrect Lucifer from the Empty, Jack's blood begins to burn, and with Mary's permission he uses his powers to teleport them to Nick's location. Arriving just as Lucifer is about to reunite with Nick, Jack banishes his father back to the Empty and turns his attention to Nick, violently breaking Nick's hand before causing Nick to burn from the inside out, killing him. The brutality of Nick's death shocks Mary, who tells Jack to go help the injured Sam. After healing Sam of his head injury, he returns to the cabin to find Mary outside. He attempts to explain why he killed Nick, but Mary tells him that something is wrong with him, and that she, Sams and Dean will help. Jack refuses to listen to Mary, and begins hearing noises in his head, screaming to be left alone as Mary continues to try to understand what's wrong. He screams at Mary one last time to be left alone. The screen goes dark and Jack whispers "Mary?".

===[[14.18 Absence]]===

:''"I killed Mary. It was an accident. I didn't mean to. I just -- I just wanted her to be quiet. I just wanted her gone, but only for a second. And I just... I thought it. It all happened so fast. I need to undo it."''

Some time later Jack is met by Dumah, who tells him Mary's death was a mistake and he isn't beyond redemption, and offers him a place in Heaven so as to make the world a better place, assuring him that will make Sam and Dean happy. The two travel to Columbus, Ohio where Dumah demands that atheist professor Harrison Tate rebuke his belief and tell his followers that God is good. When Tate refuses, Jack uses his powers to turn the professor into a pillar of salt.

Dumah then has Jack take her to Heaven, where she tells Jack that they are in dire need of more angels. While Jack can't create them out of thin air, he can forge angels from human souls. Dumah brings him to [[Heaven's Throne Room]], telling Jack it is where his grandfather received prayers and tells him to listen for any people willing to become angels. Jack proceeds to sit on the throne, and begins to hear various prayers, eventually picking up on a church group. He teleports to the church where the meeting is taking place and offers the members if they wish to become angels, unfurling his wings to their awe. When the church pastor, Ames, enters he finds the members sitting frozen and unresponsive. When Jack tells him he is taking them to Heaven to become angels, Ames doesn't believe him and demands he leave his church. But Jack, believing Ames is interfering in Heaven's work inflicts him with a biblical curse, causing worms to writhe from cuts all over his body before teleporting himself and the church group away.

Inside the box, Jack begins calling for Sam and Dean, his calls eventually turn to panic, leading to the appearance of Lucifer, telling Jack he has been played by Sam and Dean, and that they have locked him away for the rest of time. Angry, Jack begins tapping into his powers, causing the box to shake and eventually explode, causing alarms to go off in the Bunker. When Sam, Dean and Castiel arrive in the storage room, they find the Ma'lak Box destroyed and Jack appearing out of the smoke, eyes glowing gold.

===[[14.20 Moriah]]===

:''"All I ever wanted was to be good. But now I'm just empty. Even this -- I know you're here because you love me, and I want to love you back. It's just I can't."''

After escaping from the Ma'lak Box, a distressed Jack flings the Winchesters and [[Castiel]] away with [[telekinesis]] before teleporting away. Wandering the world, Jack becomes distressed at everyone always lying and orders everyone to stop, leading to a worldwide inability to fudge the truth. Next, Jack attempts to visit his grandparents, but learns from Mrs. Kline that they discovered Jack had lied about who he was during his last visit. She demands to know who he is and what he's done with Kelly. Upset, Jack orders his grandmother to stop, eyes glowing, but departs without harming her.

After being killed, Jack awakens in [[the Empty]]. He is greeted there by the [[Cosmic Entity]], who appears to Jack in the form of a black, viscous humanoid. The entity forms a smile on its face at the sight of Jack, who asks what had happened. [[Billie]] appears behind Jack and tells him that they should talk about that.
