Stiles tells Scott that he doesn't think he's grasping the concept of a car chase. "If I go faster, I'll kill us!" "Well, if you don't go faster, they're gonna kill us!" But then suddenly Kate diverts. Stiles turns on the police scanner to hear that Derek is heading further into the ironworks.
The next day at school, Scott and Stiles discuss how Scott is going to get Allison's necklace away from her. Stiles suggests talking to her and trying to ease back into a friendly relationship. "Get the necklace, get the alpha, get cured, get Allison back, in that order, got it?"
Jackson blinks out of the hallucination to the doctor telling him he can put his shirt back on. His scabs are nothing to worry about. The doctor wants to give him antibiotics and tells him he has aconite poisoning. Aconite is another name for wolfsbane. On his way out of the hospital, Jackson stops by Melissa McCall's nurse station and asks her if he can use her computer. She replies that a handsome face like his probably doesn't hear no very often. He takes it as a compliment and smiles to himself. When she asks if he's one of Scott's friends, he tells her yes, and she lets him use her computer. Jackson hops on Inquiry-It and looks up wolfsbane, but we don't see what he finds.
At school, Jackson walks straight up to Scott and tells him he knows what he is. Scott tries to play dumb, but Jackson isn't buying it. He tells Scott that he wants to be a Werewolf, too. Scott will get him the Bite, or he's going to tell Allison.
Scott immediately tells Stiles that Jackson found out. Stiles asks if Jackson actually used the word, but Scott tells him the implication was pretty clear. Stiles suggests that maybe it isn't as bad as it seems because no one would believe him. Except, Scott points out, Allison's father. Stiles starts putting together a plan and asks where Derek is. Scott reminds him that it's their quarter finals game tonight and the first game Stiles will actually play in. Stiles tells Scott to just be sure he gets the necklace.
In the lunchroom, Stiles asks Scott about the necklace. Scott tells him what happened and admits that he knows nothing about girls. Stiles announces that he has a Plan B: just steal the stupid thing. Scott asks if they can try talking to Mr. Adrian Harris instead, but Stiles tells him he's under 24-hour protective detail. Just then Scott notices that Jackson is staring at them from across the room. Jackson then bites into an apple and watches curiously as Scott reacts to the sound. Then he tries talking to him without raising his voice. Scott tries to pretend that he can't hear him, but Stiles can tell something is wrong. Scott urges Stiles to talk to him like everything is normal so he won't have to listen to Jackson, but Stiles flails because his mind is a complete blank.
Jackson has disappeared from the lunchroom, but he keeps asking Scott what else he can do. Jackson taunts Scott about being a cheater at lacrosse, and Scott starts to get angry. Jackson again threatens to ruin any chance Scott has with Allison if he doesn't get the Bite. Then he tells him he's going to have sex with her. Scott gets so angry he breaks his lunch tray in half trying to hold it in. Jackson smirks at him from the corner of the lunchroom and crunches into his apple.
Lydia approaches Jackson in the hallway and tells him that his text isn't funny. He agrees. He's breaking up with her. He asks for his spare house key back and tells her that he's decided to drop some of the dead weight in his life. She can't believe that she's been dumped.
Danny is incredulous at Stiles's request that he trace a text. "I came here to do lab work." Danny wants to know why Stiles thinks he can do such a thing, and Stiles admits to looking up Danny's arrest report. "I was 13, they dropped the charges." He refuses to help, much to Stiles's annoyance. As Danny pulls up a chair to do lab work, he looks back at Derek, who is sitting in a chair next to Stiles's bed, reading. "Who is he again?" "My cousin. Miguel." This rather obvious lie likely gives Danny the impression that "Miguel" is actually Stiles' secret older boyfriend, especially given what happens next (something we see again later in 4x02 - 117),. Derek glances up at them but doesn't say anything. Danny asks if Miguel has blood on his shirt, and Stiles tells him that he gets horrible nose bleeds. "Hey, Miguel. I thought I told you you could borrow one of my shirts." Stiles gives Derek a look and motions him toward the dresser.
Danny gives in.
Stiles is quite proud of himself.
Scott's just come down from the roof when Chris finds him. Chris welcomes him in and tells him that sometimes Allison goes for a run after school. Chris offers Scott a beer, and Scott tells him that he doesn't have to test him because Allison already dumped him. Scott still refuses the drink. Then Chris asks him how he knows Derek. Scott plays dumb.
Allison is out running in the Beacon Hills Preserve. She passes by the Hale House and decides to stop to take a closer look. She wanders through the house and finds claw marks on the floor. As she's looking at them, a figure approaches. Allison screams, but it turns out the figure is Kate. Kate followed her and asks her what she's looking for. Allison wants to know why Derek would want to kill her. Kate tells her to imagine how she'd feel if her family were trapped in a fire like this. "It wouldn't turn me into some psyschotic killer," Allison says. "You don't have to be psychotic to be a killer," Kate counters. "You just need a reason."
Chris has Scott sitting on the couch by the fire and he asks him again about Derek. Scott defends himself, asking why Chris is treating him like he's done something wrong. Chris sits down next to him and tells him that he doesn't have to be afraid of him, he's just thinking of Allison's safety. Scott replies that he thinks about that, too. Allison comes in and overhears them talking. Scott tells Chris that every choice he made in the school that night was to try to keep Allison safe. Chris tells him to go so he isn't late for his game.
Scott calls Stiles, who is in his Jeep with Derek. He tells him he got the necklace. Derek grabs Stiles's hand holding the phone and shouts into it asking if there's something on the back of the pendant. Scott insists that there's nothing in, on, or around it. Scott demands to know where Stiles is since he's first line. Coach Bobby Finstock comes over to Scott and asks the same thing. Scott says that he won't play if he's not there to start. Stiles smacks his hand on the steering wheel in frustration and asks Scott to just tell his dad he'll be a little late.
Jackson sits down next to Scott and asks him if it's the Bite that does it. Scott confirms but tells Jackson that he can't do it. He tries to explain that being a Werewolf is a whole lot more trouble than Jackson thinks it is. Scott tells him about the hunters and looks at the Argents in the stand. Jackson makes the connection between "argent" and silver, which explains the myths about Werewolf being killed by silver.
Stiles turns to run, but Nurse Jenny gets in his way. Stiles puts all the pieces together. "Oh my God, I'm gonna die," he says.
Then Derek arrives and elbows Jenny in the face, knocking her out. "That's not nice," Peter drawls. Derek tells Stiles to get out of the way, and Stiles just drops to the floor. Peter asks Derek if he thinks he killed Laura on purpose. Derek replies by attacking him. They throw each other against the walls while Stiles scrambles on the floor. Peter grabs Derek by the throat and drags him. "My mind, my personality, were literally burned out of me." He claims he killed Laura purely on instinct. Peter tells him that it was excrutiating healing so slowly and slowly coming back to consciousness. Killing Laura and becoming an alpha boosted his healing.
Peter tells Derek that he tried to warn him what was happening. He throws Derek through a glass wall, and Derek crawls along the ground to get away from him.
Peter paces after Derek as he crawls into a surgical room. Derek props himself against a wall, panting. Peter looks at himself in a mirror and then heals the still-burned half of his face. He tells Derek that he needs to give him a chance to explain himself.
Coach Finstock claps Jackson and Scott on the shoulder and gives them a pep talk. "No A in Econ if no win on field!" After he leaves, Jackson tells Scott that he's got 72 hours to get him turned into a Werewolf.
Sheriff Stilinski arrives at the stands and looks around for Stiles.
When the lacrosse team breaks their huddle to start the game, Scott stands for a moment alone.
