Magic Bullet

Kate arrives in Beacon Hills. She listens to a local news report discussing the recent line of Beacon Hills' 'animal attacks'. She scoffs at the news then switches the radio to a music channel. She doesn't know the Beacon Hills Alpha is tracking her, chasing her with Wolf speed.

 

Kate stops at a stop sign. Suddenly the werewolf lands on the roof of her car, startling her. The Wolf smashes through the car window, reaches its clawed hand through and attempts to snatch her. 

 

Kate reacts quickly, grabbing a hidden shotgun and fires through the car roof. She manages to wound the attacking werewolf. Kate tumbles out of her car and goes on the defensive, scanning her surroundings. Her attacker is nowhere to be seen.

Kate: "Come on!" (Fires off a shot.) "COME ON!"

After the Alpha retreats, Kate takes an assault rifle out of her car's back compartment. She loads the weapon with wolfsbane bullets, takes out a flashlight and calls in her brother for assistance. Scouting the area, she spots a werewolf taking to the rooftops, takes aim and shoots him with a special bullet, giving herself a satisfied smile. Kate then greets her brother who's just arrived. Chris scolds her that one of local werewolves is going to lead them to the Alpha and won't be able do that if he's dead. Kate responds she can't help stop them if one of them kills her first. She estimates the bullet she fired will give her victim 48 hours.

 

The following morning, Kate and Allison greet each other enthusiastically after not seeing each other for a year. Kate remarks that Allison now looks like a runaway model and she'll have boys lining up soon enough. Allison tells her she already has one.

 

After Allison returns from school, Kate and Chris see that Allison and her boyfriend Scott were making out in the garage to Kate's amusement.

 

Chris tries to send Scott home, but Kate instead invites him to a family dinner with the Argents, noting on his adorable brown eyes.

 

Throughout the evening, she teases Scott whilst Chris persistently grilling him.

 

She catches Scott while he's "going to the bathroom" and encourages him to use the one joining her guest bedroom.

 

Once Scott is just leaving, Kate accuses Scott of taking something from her bag. Scott swears he didn'ttake anything. Kate asks if he could prove that by turning out his pockets. But Allison confesses to taking a condom. Everyone is stunned.

 

Kate converses with Chris about the werewolves. She recalls the one she shot was lean and fast, but the one who jumped on top of her car was huge and powerful. Chris identifies the former as Derek Hale. Kate asks are they sure there's only two of them in town. Chris answers they're not yet sure.

 

Chris decdes meet that if Derek is alive, he is to be used to lead them to the Alpha. Kate excitedly looks forward to the action. Chris reminds his sister they carry it out according to the Code.

 

Kate, amused, lights a fire remembering the Hale Fire.

Kate: "Of course. I always play by the rules."

The Tell

Kate comes into Allison's bedroom to wish her a happy birthday. She also apologizes for being "a protective hard bitch" to Scott during the family dinner. She insists that they move past all "sentimental crap" and gives Allison her present early, an old family heirloom, a pendant depicting a wolf hoping that she's forgiven. Happy with her gift, Allison tells her aunt she's forgiven completely.

 

Kate shows her the symbol in the middle of the pendant, and asks does Allison ever want to learn a little something about her family, wanting Allison to start looking into the family's covert activities and join their supernatural business. Allison again thanks Kate for the gift and heads for school.

 

Chris wants the hunters to remain in the shadows and urges restraint whilst they gather more information. Kate however is impatient.

 

She takes two of their family's associates, Ulfrich and Leveque, to the Hale House to interrogate Derek Hale. Both of them remind her Chris wants everyone to wait before they make their move and that means they're not allowed to kill Derek. Kate answers it doesn't mean they can't say "hello."

 

She leads them into the house which appears deserted. She lures Derek out of hiding using the death of his sister.

Kate: "Too bad your sister bit it, before she had her first litter. Too bad she howled like a bitch ... WHEN WE CUT HER IN HALF!"

Derek roars in rage and knocks out the two men. He glowers at Kate, fangs bared, incensed at seeing her again, and Kate sadistically smirks back. She gleefully invites the werewolf to attack, whipping out a taser. Derek impulsively goes on the attack, but she gets the better of him, shocking Derek, incapacitating him.

 

Kate remarks that Derek grew up "in all the right places," admiring his physique. The sadistic huntress then fanatically tortures him with her taser, taking pleasure in watching his agony. 

 

Kate hands a gasping Derek a proposition. She admits his sister was cut in half and used as bait to capture him. Except, their people didn't kill her.

 

Derek, recovering, glares back at her. Kate surmises he thinks that she's lying to him. Derek snarls at her, "Wouldn't be the first time."

 

Kate offers that Derek listen to her say the words again and listen to her heartbeat to see if she's lying and repeats her words that they didn't kill Laura. The Alpha did. Derek absorbs this. Kate offers to kill the Alpha for him and the problem is solved. She realizes Derek doesn't know who the Alpha is. Declaring him useless and with no witnesses, she decides to kill him, but Derek evades her gunfire, running out into the woods.

 

Heart Monitor

Kate comes to see Allison in her room. She asks her niece if anything is up and Allison answers she's just sending some emails. Kate perks up asking is she emailing Scott. Allison is annoyed at Chris for grounding her and even more embarrassed for his shooting the mountain lion in the middle in the school parking lot,.

 

When Allison mentions about needing a subject for her history assignment. Kate recommends something. She directs Allison to the legend of La bete du Gevaudan on her niece's computer, giving Allison another clue to their family legacy, wanting her to join the family's supernatural business. A wolf-like creature was preying upon and terrorizing the French province of Gevaudan, killing scores of people until it was finally killed by someone who's name was Argent.

 

Lunatic

After Allison and her friends were caught up of attack at the high school by the Alpha, the Argents are now taking the hunt personally. Kate and Chris bring an annoyed Allison to school following the premises being reopened, complete with a police escort. Kate helps her get free from Chris' overprotective clutches.

 

Kate is then seen with Chris and two of their own, Ulfrich and Tyhurst, a state detective, as they gear up for a hunt as tonight is a full moon. At first, everyone assumes the Alpha won't have a target because of the new moon and he would lose control under its sway. Kate however, starts thinking and asks what if the werewolf has a reason to stay focused, covering up her assertion that she doesn't like surprises.

 

Kate teaches Allison how to use a tazer. Their practise dummy is Allison's old teddy bear, 'Mr. Bear'. Kate says the name is beyond embarassing. She has Allison swear to secrecy about the lesson ass her father would kill her. Allison has a break down over her break up with Scott. She talks about it with Kate. She comforts Allison that she's going to be breaking hearts left and right.

 

Kate however learns of Scott's connection to Derek after Allison mentions she saw them together at school. Suspicious, Kate urges Allison to tell her everything she knows about Scott regarding Derek.

 

Chris and Kate observe the latest murder by the Alpha and see Stiles, another of Allison's friends at the scene. Kate brings up the possibility with Chris that the second Beta he saw the last full moon could be a student and also informs Chris of Scott knowing Derek Hale.

 

Wolf's Bane

A couple of weeks later, the hunters follow the police chasing after Derek Hale at night. Kate and Chris are involved in the chase and Kate trails Derek's car. Chris reports Derek is running into the ironworks. Kate asks who's driving Derek's car then. Derek manages to evade the police and the hunters.

 

Kate follows Allison when she goes out on her annual morning run through the woods. Allison heads into the deserted Hale House to investigate. Kate comes up on Allison surprising her. Kate explains herself that she can't be blamed for "being concerned about her favourite niece."

 

She asks Allison what's she's doing in the abandoned building. Allison answers she's looking for answers why Derek Hale would want to kill people, herself and her friends. Kate tells her niece to imagine how she'd feel if she and Chris would be caught in a fire like the one that torched the house. Allison remarks it wouldn't turn her into a psychotic killer.

Kate: "You don't have to be psychotic to be a killer. You just ... need a reason. And even then sometimes, you can surprise yourself."

Kate asks Allison what does she want. Allison rants that she wants to not be scared, she wants to feel stronger, to be able to protect herself. Pleased with Allison's answer, Kate tells her to be patient and she might be able to get her what she wants.

 

At the high school lacrosse game, Chris, Kate and Allison are in attendence. After Allison points out Jackson to Kate, Kate responds positively to his looks and teases Allison should be all over him. Kate notices the claw marks on the nape of Jackson's neck. She whispers to Chris could someone be turned into a werewolf by a scratch and converses the possibility with him that Jackson is the second beta.

 

Co-Captain

Late at night, Kate and Chris come back home, after practising the hunter's trade and skills. Kate remarks that setting off their flashbangs so close to civilization is bound to draw them some attention. Her brother answers her he knows when to be conspicuous when he needs to. Kate enquires that they should be teaching Allison their skills, in light of recent events. Chris insists Allison's time isn't yet to come.

 

Kate rearranges some equipment at the desk. In the corner of her eye, she spots Allison hiding in her car, eavesdropping. Kate hides that she ever saw her niece, seeing an opportunity. She leaves a flashbang behind for Allison to find then follows Chris into the house. A few minutes later, Kate doubles back to look in the garage and sees Allison holding the flashbang and an old one Chris threw in the trash. She smiles, pleased that Allison is searching for answers.

 

At the high school, Kate is tracking Jackson Whittemore. She witnesses him following Derek Hale out of the school.

 

Kate follows the two to the Hale House. She gets into position and opens fire upon the house with wolfsbane bullets and eventually captures Derek.

 

Later, Kate sends Allison a text, telling her to meet with her saying they neded to talk. Allison meets up with her. Kate takes Allison to an underground dungeon. Allison is perplexed, asking Kate where are they. Kate resonds with 'the basics'. She tells her niece that every family has secrets, but their own are a little different, showing Allison into a darkened chamber.

 

Allison looks up. Kate, full of herself, turns on a light, illuminating a captured, weakened, shapeshifted Derek Hale, imprisoned by manacles and wired up to an electrical device to subdue and torture the werewolf. Smiling wickedly, Kate turns to a shocked, rattled Allison:

Kate: Isn't he beautiful?  

Formality

Kate turns on the device wired up to Derek to electrocute him, torture him in front of a horrified Allison. Kate shows off Derek's supernatural attributes to Allison to have her niece believe the existence of shapeshifters and share Kate's own monstrous views towards them attempting to pull her niece towards her way of thinking. Allison is appalled at her aunt's obvious sadistic tendencies. Kate responds "Everything's a joke to (herself)."

 

After finishing her showing off Derek, Kate updates Allison on the werewolf situation in Beacon Hills, the Alpha, the second Beta, and the revelation that their family hunts the supernatural all her life and for generations. Kate tells Allison her parents still haven't decided to tell her yet because Kate thinks they just see Allison as some frightened little girl who'd run crying into a corner when she finds out the truth, but Kate herself sees "natural talent", grooming Allison to use her for her own ends.

 

Kate tells Allison to go back to school, be a normal teenage girl and prepare for the formal before the next part. Kate reminds Allison that she said she wanted to be stronger and she's going to get to do that by helping Kate catch the second Beta. 

 

Kate returns to the chamber to personally torture Derek for her own pleasure and for information. She carries out her torture with an associate, Marcus, but Chris is unaware of her actions. She interrogates him for the identities of the second Beta and the Alpha.

 

Derek refuses to cave in, and distracts her with the accusation does Kate want to torture him or talk him to death. Kate answers she just wants to catch up and brings up their sexual affair from when Derek was a teen, but "burning (his) family alive was fun too", easily bringing out the werewolf's anger.

Kate: "I love how much you hate me."

After a day of keeping Derek prisoner and he steadfastedly refuses to give up, and with Chris starting to get suspicious, Kate decides to just kill Derek. She realizes Derek never told anybody about their affair incluing his sister. She takes wicked pleasure in his showing guilt and torment. She amusedly tells the werewolf he got tricked "by a pretty face", a werewolf who falls for a beautiful girl from a family who kills the werewolves. She follows up with the surmisation that maybe history would be repeating itself where he would be inadvertently helping her track down then the rest of the Pack. It'll be history repeating itself, which gets stuck in her head. She realizes the second beta isn't Jackson Whittemore, because Jackson isn't in love with Allison, Scott is the second beta.

 

Code Breaker

Chris and Allison return home at the Argents' residence and it comes out Allison also knows everything about their family. Chris is furious, partially at Kate for revealing everything to Allison against his wishes. Kate snarks, trying to play innocent that Allison found out herslef. Chris yells that he knows about the clues she's been leaving her. Kate fires back that Allison needs to know.

 

Chris follows up with asking Kate why is she here, since she isn't fond of being in Beacon Hills, asking where her priorities lie. Kate, flabbergasted at her brother, responds she's here to help catch the Alpha, which is running around the town randomly killing people. Chris tells her the Alpha isn't killing at random. He learned from their man in the Sheriff's station that the Sheriff can trace every murder back to the Hale House fire. Kate, realizing how close Chris is, hurriedly justifies that that makes all the more reason for Allison to be in the know. Outsiders have always suspected, blamed their family for the fire and guarantees that they're the culprit's last targets.

 

Chris decisively says he's aware, so Kate is taking Allison out of town to the safehouse in Washington. Kate amusedly complains that she's going to be benched, but Chris gets in her face and teels her he wants she and Allison on the road within the hour, leaving no room for arguement.

 

Kate isn't planning on leaving town, however. She and a silent Allison are in the car when Chris comes out to see them off. Kate insists he's not going to find the Alpha without her, but Chris just sends them off.

 

Kate instead takes Allison to the hospital where Lydia has been hospitalized after being Bitten, savaged by the Alpha to ostensibly show her niece what werewolves are capable of. Allison comes back into the car where Kate manipulates her further to get Allison on her side of things.

Kate: "Do you get that now? It's what they do. And they can't help it."

Allison: "All of them?"

Kate: "Yes, Allison. Even Scott."

With a groomed and furious Allison completely at her disposal, Kate has the two of them gear up and head to the Hale House.

 

Lateron, the two easily catch both Scott and Derek in their sights. Kate coaches Allison who then puts arrows in Derek in the chest and leg and blinds Scott with a flashbang. They walk up to the two disabled werewolves.

 

Allison confronts Scott over his lies. Kate, annoyed at their exchange, orders Allison to quickly shoot Scott before she shoots herself. Allison pauses, having thought they were only going to catch the two. Kate says they now kill them, shooting Derek at point-blank range with her firearm, horrifying a hesitant Allison. Completely fanatical and egotistical, Kate realizes that Allison isn't going to go through with killing Scott and moves in to murder the teenager herself, pushing a protesting Allison to the ground and levels her gun at Scott's head with a sadistic smile.

Kate: "I love those brown eyes."

Before she pulls the trigger, Chris' yell comes out of the night, stalling her. Chris has arrived and disgustedly confronts Kate, telling her he knows what she did, that she orchestrated the Hale Fire and orders her to lower her gun. Kate justifies she did what "(she) was told to do", but Chris points out all her crimes, now including threatening a sixteen-year-old, that she has broke the code to her annoyance. She just aims her gun at Scott, but Chris pulls his gun on her, again ordering her to put hers down. He fires a warning shot over her arm. Kate, astounded, finally obeys.

 

Just then the door to the Hale House opens, and the four people go on alert, disregarding all the altercations that just happened. They know Peter Hale has arrived. The alpha werewolf speeds out of the house and corrals them, catching them all off guard and disables Chris, then Allison and Scott.

 

Kate covers all her bases with her gun drawn. She impatiently calls out to the werewolf. Suddenly, she is caught in a painful iron-clad grip by the alpha, Peter Hale.

 

He breaks her arm, causing her to drop her firearm and drags her painfully into the Hale House, about to exact his revenge on her for the Fire, having overheard the previous exchange.

 

The alpha has Kate help captive by the throat with his claws. Allison runs into the house to try and save her aunt. Kate is helpless, about to die and she knows it. Peter taunts Kate that Allison isn't damaged like her, knowing that Kate cares about her, despite her crimes. The vengeful werewolf gives Kate a chance to save her niece.

Peter: "Apologize. Say that you're sorry for decimating my family. For leaving me burned and broken for six years. Say it. And I'll let her live.

Kate stammers and looks at a terrified and devastated Allison.

 

Kate: "I'm sorry."

Kate is apologizing only to Allison, not at all remorseful over the carnage she caused and revels in, not at all sorry for Peter or the people she murdered in the slightest. The werewolf knows this. He tears Kate's throat out, killing her.

 

After Peter is killed, Chris leaves the Argent pendant on Kate's corpse so the police will uncover her part in the fire and pin the murders on her. Sheriff Noah Stilinski finds Kate's corpse and the necklace and the case is closed.
