Raised by an elderly grandmother, Annie Jones was reported abducted on February 29th, 2006, outside of Kenosha, Wisconsin, when she was 8 years old. She was kidnapped by the vampire Celia and her nest, and renamed Alex. She was used as a blood slave and as a lure, bringing unsuspecting victims to the nest for her family to feed on, and used as food when the hunting went dry. In 2014, aged 16, she ran away out of guilt over what she was doing. The vampires re-captured Alex, but she was rescued by Jody and the Winchesters.
After being taken in by Jody Mills, Annie continued using the name Alex. In 2015, Claire Novak also moved in with Jody Mills, following the death of her mother. She and Alex developed a slightly fractious sibling relationship, with Alex trying to live a normal life and Claire determined to become a hunter in her own right.
Annie arrives in Sioux Falls, South Dakota, where she is arrested by Deputy Frank and thrown in jail. After getting a breaking-and-entering call, Frank leaves her alone and her vampire "brother" Cody arrives, having hunted her down. Scared, Annie cowers until Sheriff Jody Mills arrives and decapitates Cody with a fire axe. Annie refuses to thank her as Cody was her "brother."
Jody calls in Sam and Dean, who try to get information out of Annie after determining she's not a vampire. Annie, demanding to be called "Alex," recognizes them as hunters and refuses to tell them anything to help them hunt her "family." Using her bus ticket, Sam and Dean track the nest to O'Neill, Nebraska, and go to hunt it down while Jody takes Annie to her family cabin for protection.
At the cabin, Annie refuses to sleep or eat and coldly deduces that Jody's family was dead. That night, after Jody informs her that her grandmother, all that was left of her human family, was dead, her vampire "family" arrives and kidnaps her, knocking Jody out.
At the nest, Annie is surprised to learn that Celia forgives her even though her actions led to the deaths of Cody and Dale. Alex explains that she couldn't deal with the guilt of her actions anymore and agrees to be turned into a vampire when asked. Celia feeds Annie her blood and when Jody arrives to rescue her, she finds Annie adjusting to being a vampire. Celia knocks out Jody and tries to get Annie to feed on her, but Annie tries to spare Jody as she was so nice to her. Jody realizes that Celia lost a daughter of her own named Alex which is why she renamed Annie, to replace her daughter. Jody admits she was trying to do the same with her own dead family and Annie and Celia go to kill her. However, Annie injects Celia with Jody's dead man's blood, saving Jody to the shock and anger of Celia. Jody has Annie turn away and then decapitates Celia. As Annie hadn't drunk any blood, Sam and Dean, who had killed her "brothers", are able to cure her.
Later, at Jody's cabin, Annie recovers from the vampire cure which leaves her sick for a few days. Jody offers Annie her support, telling her she will be there for her and that no one can understand what Annie has been through, having lost her entire family. Annie accepts Jody's support and points out that Jody can understand, as she is in a similar position.
While Jody is at a mandatory sheriff's retreat in Hibbing, Minnesota, she checks up on Alex, telling her she has faith that she won't be throwing a "kegger" in her absence. Jody later calls Alex again, where it would appear that Alex is in the middle of raucous party. She hangs up on Jody after Jody asks why she is hearing fireworks.
As Alex leaves school with her boyfriend Henry, one of her friends approaches her, having heard that she and Henry are in the lead for Prom Queen and King. Alex and Henry joke about it before Mr. Phelps walks by and reminds Alex about a test she has the next day. Alex is then picked up by Jody, who tells her she is proud of her for fitting into a normal life. As they leave, Jody notices birth control pills in Alex's bag.
Returning home, Jody and Alex are surprised to find the Winchesters there, having been called in by Claire, to Jody and Alex's annoyance, as neither of them believes there's a monster around. At dinner, Alex tells the Winchesters that the weird things Claire has been hunting have been based off of a crime blog, prompting the annoyed Claire to reveal that Alex and Henry plan to sneak off to Jody's cabin to have sex, prompting Jody to give Alex a highly awkward sex talk. While talking to Dean, Jody tells him that things were rough with Alex for awhile, but she'd started to turn things around, even dating the most popular guy in school.
The next day, Alex and Henry arrive at school to find Mr. Phelps' body hanging upside down from the flagpole. School gets cancelled as a result and Alex leaves with Henry and they walk along a stream. Alex is distraught by Mr. Phelps' death as he'd believed in her and because of the way he died. She tells Henry there's awful things out there. Alex admits she wasn't always the good person she is now and has done awful things in the past, remembering the terrible things she did while with Celia and her family of vampires. Henry reassures her that he doesn't care about her past and they kiss.
That night, Dean calls Alex asking where she is and tells her he's coming to pick her up, as the custodian is a vampire. Alex tries to leave, telling Henry he needs to go but he attacks her, revealing himself to be a vampire.
Alex is dragged to the vampire nest where she is horrified to discover Claire and Jody tied up. The custodian, Richard Beesome, explains that three years before, in O'Neill, Nebraska, he had rescued her from a "sleezebag" outside a bar and given her a ride home, where her vampire family attacked him and turned him. Afterwards he went home and into a bloodlust that led to him slaughtering his own family. Alex tearfully apologizes, telling Richard she had no choice, but Richard points out she could've left him outside of the bar where he found her. Henry and Richard explain that Richard wanted revenge and wanted to do it by making her suffer. To this end, he turned Henry into a vampire and sent him after her. The plan was that once Henry built her up, Richard would tear her down by taking her teacher, boyfriend, and family before they fed on her. Henry tells her that his affection for her was completely fake and makes fun of her, causing Alex to spit on him. Richard drags Claire over to feed on her and Alex confirms Jody's story that the Winchesters are hunters who killed Alex's entire nest. Alex is unable to convince Henry to help and offers herself up to help Richard and Henry feed like she did her old nest if they let Claire and Jody go. Richard says he'll take her up on her offer before starting to feed on Claire. However, sensing Sam nearby, the vampires leave to fight him. As Henry fights Sam, Richard grabs Sam's machete and prepares to kill Alex with it. Before he can, Claire stabs him in the back with a crowbar, distracting Richard long enough for Dean to decapitate him. Freed by Dean, Alex confronts the subdued Henry who tells her he should've "tapped that." Alex punches him before Claire cuts his head off.
The next morning, Alex and Claire attempt to cook breakfast for Jody and Alex blames herself for Richard nearly killing Jody. Claire tells Alex that Richard wanted to kill her for what the vampires did, not Alex, who had no choice. Jody reminds Alex that she was willing to give her life to save them which is goodness and is what's scary about family: it gives you a lot to lose. Later, Alex tells Sam she plans to go back to school and if other vampires come for her, she will be ready. Alex tells them that when she gets her life together, she may move on as she can't be around monsters. She then watches with Claire and Jody as Sam and Dean leave.
A brainwashed Mary comes to Jody's house, attacks her, and is about to kill her when Alex comes home and attacks Mary to save Jody. She buys Jody time to knock Mary out and restrain her. Alex tends to Dean's wounded knee while she and Jody explain what happened. She leaves to get Dean some painkillers and scotch when Sam brings Toni Bevell into the house to undo Mary's brainwashing. Toni is forced to admit that the brainwashing is permanent and that she can't be saved and they will all die. Sam decides to recruit an army of hunters to attack the British Men of Letters before they target the American Hunters. Alex answers the door for Walt and Roy before their meeting starts and Sam explains their situation and how they can resolve it by taking the fight to them. As they start to take off, Jody sends Alex to meet with Donna at a safehouse in the meantime. Before she leaves, Alex tells Jody to "kick it in the ass."
- The missing poster marks her date of disappearance as February 29, 2006, but the leap year only occurs every four years and did not occur since 2004 in that time until 2008 when it was used in 3.13 Ghostfacers.
