Wolf Moon
Allison has just moved to Beacon Hills with her family in the middle of sophomore year. Allison is embarrassed that she didn't bring in a pen. She is introduced to her new English class. She meets Scott in her English class. He turns around and offers her a pen. She thanks him. Allison's immediately intrigued by this kind boy who somehow knew that she needed a pen.
After class, Lydia quickly scoops Allison up and adds her to her clique, claiming she has good fashion sense. Lydia and Jackson invite Allison to watch the lacrosse practise and to come to a party on Friday night. She says she'll come to practise but she turns them down for the party saying it's 'family night'. Allison comes to lacrosse practise. She sits next to Lydia. She sees Scott in the goalie's position and notices he's pretty good after catching several balls thrown in his direction.
Allison and Scott get close after she hits a dog with her car and comes to the vet clinic in tears for help. Scott helps calm the dog down. Scott gives Allison a spare shirt so she can change in the next room. They flirt while he cares for the animal. Scott tells Allison she can touch the dog now, and Alison gives the distressed animal a pet. Allison feels ashamed to have been crying like a little girl after hitting the dog. Scott reassures her, he'd react like that. It becomes obvious that the two have instant chemistry. Scott asks her maybe she'd like to go to the party with him. This time Allison agrees to go. Allison sees, and waves at Scott during lacrosse practise the next day.
Scott arrives at Allison's house to pick her up. At the party, Allison and Scott have a great time. Allison is confused at Scott's sudden behaviour, his heavy breathing and he suddenly leaves her at the party. She isn't sure what happened and gets a ride home with Derek Hale. Scott asks her for a second chance, and even though he can't fully explain what happened, she gives it to him. Her father coes to pick her up.
Second Chance at First Line
Unbeknownst to her, Allison becomes the fulcrum that Lydia uses to manipulate Scott into playing in his next lacrosse game. Scott was going to bow out because the game takes place on the full moon, but Lydia won't let her team lose. She introduces Allison to other hot guys on the lacrosse team, trying to force Scott to do what she wants. Allison just thinks that Lydia is being nice to the new girl. When Scott comes by to assert himself, he notices that the jacket Derek had taken from Allison is back in her possession.
She doesn't see Scott again until just before the game. He was lurking on the roof of her house and then raninto the path of Chris's car as he was pulling into the driveway. Allison runs out to check that Scott is okay. At the game, Lydia forces Allison to hold up signs cheering for Jackson, which enrages Scott. Allison is trying to be a good friend, but she feels like she's betraying Scott by doing it.
She doesn't realize that her whispers of encouragement actually help Scott control his bloodlust on the field. After the Cyclones win, Allison goes to find Scott. She follows him into the boys locker room, and despite feeling afraid and watched, she keeps looking. She eventually finds him shifted back to a human. They get to talking and she compliments his playing the game. They become giddy and kiss.
Pack Mentality
A few days after the game, Allison and Scott get roped into a group date with Lydia and Jackson. Jackson didn't want to go bowling without some real competition, and Allison took up his challenge, dragging Scott along with her.
Lydia and Allison spend their time before the date trying to pick out clothes. Lydia disapproves of most of Allison's choices. Once they find something, Chris tells them that they can't go out because of the Sheriff's curfew. Allison isn't taking no for an answer, and she sneaks out by doing a flip off the roof. At the bowling alley, it's clear that Scott can't bowl. Allison feels protective of him and gets upset that Jackson keeps making fun of him. She encourages Scott by suggesting that he think about something else. She quietly tells him to think about her naked. It works, and they are able to shut Jackson up. She also notices that Lydia is a much better bowler than she pretends to be and that she's hiding her real abilities to make Jackson feel like a better man. Allison tells her she should stop, but this is how Lydia knows how to get what she wants.
After the date, Allison tells Scott that she wants to go out with just him next time. They share a sweet kiss on the porch.
Magic Bullet
Allison sees her Aunt Kate as more like a sister than an authority figure, and she's thrilled when Kate comes to town.
Allison makes plans to "study" with Scott which is really an excuse to make out in her room. She takes the lead in their encounter, although Scott is always careful to ask whether or not he's pressuring her. While they are alone, she tells him about all the talents she tried to have but was terrible at, photography, poetry, art, and eventually shows him that she's a champion archer. They are out in the garage kissing when her father comes home. He's less than thrilled, but Kate steps in and invites Scott to stay for dinner. It is an awkward meal. Chris is openly hostile toward Scott, and Allison keeps trying
to make him stop. When Kate accuses Scott of having stolen something from her room, Allison confesses to taking a condom from Kate's bag. It's an awkward moment all around.

The Tell
On her seventeenth birthday, Kate gives Allison a silver medallion with the Argent family crest. Kate tells Allison to look it up and find out what it means.
Allison had hoped that no one would know it's her birthday because she's embarrassed about being a year older than everyone else, but Lydia found out. And because of the balloons she put in Allison's locker, Scott found out, too. Scott figures out she had to repeat a year because she moves around so much. Allison, touched, gives Scott a kiss, because everyone before always assumes she either flunked out on year, or did she "have a baby". Scott and Allison skip school
to spend the day wandering in the woods. Allison thanks Scott for a perfect birthday. They share a sweet moment with Scott telling Allison she has a tell, her eyebrows, so he knows whether she's lying or not. Allison challenges him to ask if she's lying when she says she wishes her parents weren't coming home from the parent-teacher conference so she can spend the night with him. They return to school during conferences and are confronted by their parents for their skipping school. Everyone goes into a panic in the arking lot. Chris shoots a mountain lion which is the cause of the commotion.

Unbeknownst to her, it's her influence over him that helps him maintain control. Stiles calls her Scott's anchor.
Night School

Scott looks at her in pain and regret, but goes anyway. Allison nonetheless kisses him.
After the kids get outside and the cops arrive, Allison calls her dad. Scott runs up to her.

Wolf's Bane

Late at night, Allison notices her necklace is missing. She searches the garage. She hides in a car when her dad and Kate enter. She's confused over the context of their speaking together particularly her dad saying his life was saved more than once by a series of peculiar arrowheads, and Kate remarking that Allison could be learning these skills, to which Chris replies "not yet."
Kate leaves behind a peculiar arrowhead and they both leave. Allison picks it up, suspicious. She is unaware Kate spying on her from behind.
Allison takes Lydia out into the woods the next day. Allison tells Lydia Jackson asked her to the winter formal, but just as friends, asking Lydia if she minded. Lydia replies no. She tells her so-called close friend she knows Lydia kissed Scott in the Coach's office.

Formality
Allison leaves the dungeon shaken, upset. She now knows that her family has been lying to her and that the universe does not run on the rules she thought it did.
She speeds and gets caught by the Sheriff, but he lets her go without giving her a ticket. After thinking it over, Allison remembers her vow to be strong and not show weakness. Allison decides the crying girl isn't her "this isn't me". She turns to archery. She comes up in an empty alleyway and shoots at a wanted poster of Derek.
She agrees to go with Jackson to the winter formal and goes dress shopping with Lydia. Lydia is buying her dress. To make up for having made out with Scott, but Allison also makes Lydia take Stiles to the dance as part of her punishment. While shopping, an unnamed man approaches her and talks to her about which dresses match her perfect skin. She is suitably creeped out but lets him continue to make her uncomfortable rather than say or do anything about the inappropriate behavior of an adult. Allison is lured outside by an announcememnt over the intercom that her car is being towed.
At the dance, Allison turns down Jackson's offer of alcohol. She is not happy with Jackson being her date. and is glad to see that Scott found a way in, despite his academic probation. She watches with amusement as he escapes Finstock and
immediately agrees to dance with him. It's a lot like old times. Now that she knows about werewolves, she tries to downplay the things she was trying to tell him the other night, while Scott is trying to tell her that he believes her. They stop talking.

Allison gets into the car with Kate, with her father pomising they'll talk about everything. Allison keeps mulling over Scott at the formal, him telling her he loves her, but snapping to the fact he is also a werewolf. Kate however, brings Allison to the hospital. Allison checks on Lydia whom is bedridden, while partially hallucinating her as blood soaked due to her emotional stress, which serves to harden her resolve. Kate tells Allison that all werewolves are killers, and they can't help it.
Together, Kate and Allison hunt Scott and Derek as they escape the dungeon where Derek was being held. Allison shoots Derek twice with arrows, once in the chest and once in the leg.
