|“|| Scott: "What do you want from us?"|
Kate: "I want a little bit of insight, Scott."
Scott: "To what?"
Kate: "My family. The Argent family has been around for over four hundred years-- A powerful, wealthy, aristocratic family of Werewolf Hunters. But yet, somehow, in less than a year, this great family is decimated by a teenage boy. So, my question is simple... What the hell is so special about Scott McCall?"
Scott: "You want me? Take me. Just me."
Kate and Scott initially met in Season 1, when Kate came to Beacon Hills to visit her brother Chris, her sister-in-law Victoria, and her niece Allison (the latter of whom was Scott's girlfriend) while also helping them hunt the Alpha Werewolf who was terrorizing the town. Though Kate didn't know it at the time, Scott saw her for the first time out late one night where she was pursuing the Alpha and had shot Derek Hale with a Nordic Blue Wolfsbane-laced bullet. Despite this, they weren't formally introduced until the following evening, when Chris and Kate walked in on Scott and Allison making out in the garage, an act that Kate found amusing and adorable. She encouraged Allison's romance with Scott and constantly complemented him on his sweet brown eyes.
However, when Kate finally realized that Scott had recently been turned into a Werewolf by the Alpha and was a reluctant ally to her former paramour, Derek Hale, Kate attempted to kill him, though she was stopped by Chris, who reminded her of their Hunter Code, at the last moment. Kate was then seemingly killed by the Alpha when he ripped her throat out with his claws, but in reality, Kate had actually been scratched so deeply that she was turned into a Werejaguar. Following Kate's escape from the Calavera Family of Hunters in Mexico, Kate set her sights on learning control over her transformations, rejoining her family in hunting the supernatural, and taking her revenge on Scott, whom she blamed for the decimation of the Argent line, despite the fact that it was her role in the Hale House Fire that kick-started the events that led to the harm and death caused to her family.
Once the Deadpool had ended, Kate used her Werejaguar powers to turn Scott into a Berserker with the intention of setting him loose on his pack, which would then leave them no choice but to kill him to save themselves and would keep her hands metaphorically clean in the process. Unfortunately for her, Scott's bond with his newly-turned Beta Liam Dunbar allowed him to turn back into his True Alpha self. Kate has since gone on the run from the Calaveras and her brother Chris, leaving Kate and Scott's feud unresolved.
Throughout Teen Wolf Edit
In Magic Bullet, Kate invited Scott for dinner after caughting him with Allison in the garage. Scot, that was looking for a cure for Derek's wound by the Hunter, asked where was the bathroom and Kate respond it was in her bedroom. Scott finds the bullet but after dinner, Kate asked if Scott tooked something from her bag and Allison takes the fault.
In Code Breaker, Scott and Derek were nearly The Hale House to stop Peter when they're attacked by Allison and Kate. As Allison didn't believe in anything Scott was saying. Kate decided to kill both werewolves, Allison realizing she cometted a mistake for trusting her psychothic aunt tries to stop her but is useless, Chris appears and stops her and blames his sister for breaking the code by killing a lot of innocent people of the Hale Family. As Peter still wanted a revenge for his family's death, kills Kate, ripping her throat out.
In The Dark Moon, Scott and his friends go to Mexico to rescue Derek from the Calaveras but after knowing that the Calaveras didn't know where Derek was as well. Araya prepares a test: Araya'll ask Scott where is Derek if he doesn't answer he'll be eletrocuted and if Kira refuses to turn the dial on him, Araya'll turn the dial on Lydia. Scott says it's okay as he can heal but he insists that he doens't know who kidnapped Derek. Araya angry insists Kira to put the dial on ten but Araya does that herself. Scott screams in pain and then remembers a flashback in Wolf's Bane that Kate was with Chris assisting the game asking him if she can turn by a scratch and Chris affirms if they go deep enough. He roars, breaks his chains and tells Araya Kate has Derek.
In A Promise to the Dead, As Scott and Kira were having a date in Derek's loft, Kate and a Berserker invade the loft. As Kira fights the Berserker, Scott fights Kate but she overpowers him, she says that her family has been around 400 years and says Scott is the teenage boy who decimated her family. She takes the two of them to La Inglesia where puts Kira in some kind of Dungeon and ties Scott up to a stone table and she turns him into a Berserker.
In Smoke and Mirrors, Kira tried to escape from her Dungeon, Scott now turned into a Berserker by Kate, stops her until Kate roars at him to demand him stop. Kira asks to Kate what she did to Scott and tells the history of after being resurrected. The Berserkers suddenly realized when she arrived to this church, they had to respect Kate as she was turned into a werejaguar. As she's called La Loba, she also means she's called The Bone Woman and Scott stabs Kira. As Kate is defeated by her ex-boyfriend Derek who has now the ability to shift into a full wolf. she tells Chris that Scott and her friends are the responsibles for Allison' death, her brother firmely tells Kate that Allison died saving her friends' lives and Kate runs away leaving Chris and the Calaveras follow her.
- Both Kate and Scott were turned by Peter Hale. While Kate was turned by a scratch, Scott was turned by a bite.
- Kate doesn't think of Scott as the hero most people see him as. This is both due to him being a Werewolf and Allison's death.
- Scott and Kate are both were-creatures.
- Why Kate turned into a Werejaguar, instead of a werewolf like Scott is currently unknown, but some speculate that this could go back to the subject of the shape you take reflecting the kind of person you are.
