Isabel slowly awakes to the sound of stumbling feet on the ground, feeling her body shake from the vibrations. She opens her eyes to see Deaton holding up Derek and realises she's lay on the floor of the Hale house still; it wasn't a nightmare.

"You're going to be weak for several hours." Deaton tells Derek, holding him up so he doesn't fall.

Derek breathes heavily as he looks down at his arm. He quickly looks over at Isabel, seeing her slowly sit up, face scrunched in pain.

"It actually happened." Derek says in disbelief as he slowly moves over to help Isabel.

Deaton quickly makes his way over, helping Isabel sit up. He slowly helps her stand as Derek looks at her in realisation.

"He took your wolf side." He whispers, but Isabel and Deaton still heard it.

"Don't worry - you're still an Alpha." Deaton tells the wolf. "He siphoned the majority he needed from Isabel." He explains, watching as Isabel silently stands on her own. "You'll be weak, Isabel. Your wolf side is his now."

"Where is he?" Derek angrily asks.

"I wish I could tell you."

"Then how about you tell me what you're doing here, and why you're even helping us?" Derek motions between himself and Isabel.

"Helping your family actually used to be a pretty important part of my life. Helping you was a promise I made to your mother." Deaton tells Derek. "Alongside of the witches." Deaton motions to Isabel.

"You're the one my sister talked about. She said you're a kind of advisor?"

"She was right. And I have some advice that you need to listen to very closely right now. What Peter managed to do doesn't come without a price. He'll be physically weak, so he'll rely on the strength of his intelligence, his cunning. He's gonna come at you, Derek. He'll try to twist his way inside your head, preying on your insecurities. He'll tell you that he's the only way you can stop Gerard. Do not trust him."

"I don't trust anyone." Derek gruffly speaks, giving a gentle look to Isabel who stands with her arms wrapped around her body, her face looking lost.

"I know - if you did, you might be the Alpha you like to think you are. And, unfortunately, the one person you should trust? Doesn't trust you at all." Deaton tells Derek.

"Scott." Derek whispers.

"He's with Stilinski right now." He tells him. Isabel's head shoots up at the name. "You need to find him - you need to find him as fast as you can. I've known Gerard for a long time. He always has a plan. Something tells me it's going exactly the way he wants it to." Deaton tells him, looking down at the hole in the floor.

"She's on her way here." Scott tells Noah, who's eyes look behind Scott. Scott looks at him confused. "Sheriff...?" He turns, watching as Matt pushes Stiles into the room with a gun at his back.

"Matt? It's Matt, right?" Noah asks, hands raised in a surrender. Matt nods and looks at him amused. "Matt, whatever's going on, I guarantee you there's a solution that doesn't involve a gun."

"You know, it's funny you say that, because I don't think you're aware of just how right you are." Matt tells the Sheriff as Stiles watches cautiously.

"I know you don't wanna hurt people." Noah tries.

"Actually, I wanna hurt a lot of people. You three weren't on my list, but I could be persuaded. And, one way is to try dialing somebody on your cell phone, like McCall is doing." Matt speaks, causing Scott to pull his hand out of his pocket, caught. Stiles turns to him and watches as he shuts his eyes. "That? That could definitely get someone hurt." Matt motions the gun to the desk. "Everyone! Now!"

"Come on." Noah nods, motioning for the two do as they are told. Everyone removes their phones from their pockets and places them on Noah's desk.

Matt uses his gun to move the group where he wanted, pointing it at Stiles as he made him handcuff his dad to the bench in the cell room. Matt laughs pathetically at Stiles.

"Tighter."

"Do what he says, Stiles." Noah nods. Stiles angrily tightens the handcuff.

Matt grabs him and pushes him in front of him, making Scott and Stiles leave Noah behind. Scott freezes as he looks down a hallway, spotting three dead officers covered in blood.

"What, are you gonna kill everyone in here?" Scott asks incredulously as they all look at Jackson's work.

"No, that's what Jackson's for... I just think about killing them, and he does it." Matt chuckles, pushing them further down the hallway and back to the Sheriff's office.

He makes the two shred all of the evidence and delete everything they had on the computer.

"Deleted. And we're done. All right? So, Matt, since all the people you brutally murdered deserved it because they killed you first - whatever that means - I think we're good here, right? So, I'll just get my dad, and we'll go, you know? You continue on the whole vengeance thing. Enjoy the Kanima." Stiles irritably tells the boy sat watching them.

The three turn to the window as headlights shine through the blinds.

"Sounds like your mom's here, McCall." Matt smugly smiles.

"Matt, don't do this. When she comes to the door, I'll just tell her to leave. I'll tell her we didn't find anything. Please, Matt-" Scott pleads as the entrance door opens.

"If you don't move," Matt chuckles, "now, I'm gonna kill Stiles first, and then your mom." Matt escorts the two to the door. "Open it." Matt demands.

"Please." Scott tries again.

"Open. The. Door." Matt demands again.

Scott closes his eyes and reaches for the door, breathing in relief as Derek stands in the doorway.

"Oh, thank God." Scott whispers, but Derek says nothing.

He falls the the ground on his back at Stiles and Scott's feet as Jackson stands behind, paralysing him.

Matt smirks at Jackson as he makes his way into the room; half transformed. Everyone's head turns to face the doorway again as the front door opens again.

Matt frowns as Isabel slowly makes her way into the station, having been left by Derek - who was faster than her. She holds her body up against the wall, using what energy she had to push herself along.

Scott and Stiles gasp as they watch Isabel make her way to the door, freezing in the doorway as she spots Derek on the floor and Matt leaning over him. Matt clenches his jaw as she looks at him, terrified.

Scott and Stiles look over her, still in her tight, no-longer white dress, covered in dirt and blood. Stiles eyes fill with fear as he looks over to see the huge smile on Matt's face.

"Welcome to the party, Izzy." Matt creepily tells the girl, tilting his head and pointing the gun at her as Jackson moves to his side.

Isabel freezes as she looks over to see Scott and Stiles watching her worriedly as they stood in the room. Isabel takes a shaky breath as she realises Matt is the one controlling the Kanima.

She slowly raises her hands in a surrender, cautiously making her way toward Matt and Jackson. Matt smiles as she approaches, taking in her outfit.

"I never got to tell you how beautiful you looked tonight. Even if it is ruined now." Matt shrugs, slowly looking her up and down as she stands in front of him, body shaking.

He reaches a hand out to hold her waist, but is stopped by Derek's voice filling the silence.

"This is the one controlling him? This kid?" Derek patronisingly speaks, attempting to take Matt's attention off of Isabel.

Matt smiles as he turns back to Derek. Scott quickly moves Isabel in between himself and Stiles.

"Well, Derek, not everyone's lucky enough to be a big, bad Werewolf." Matt tells him sarcastically. "Oh, yeah! That's-that's right. I've learned a few things lately. Werewolves, Hunters, Kanimas... It's like a frickin' Halloween party every full moon." Matt turns to face the three teens.

He spots Stiles now holding Isabel close to him protectively. His arm around her waist. He angrily frowns and focuses on the pair.

"Except for you, Stiles. What do you turn into?" Matt patronisingly asks.

"Abominable Snowman. But, uh, it's more of, like, a wintertime thing, you know? Seasonal." Stiles jabs back sarcastically. Isabel watches in fear as Matt motions toward Stiles at Jackson.

"No!" She cries out, blocking the way but Jackson pushes past her and slashes Stiles' neck; paralysing him immediately.

Isabel tries to hold Stiles up but she is too weak, losing grip as he falls to the ground. Scott tries to move forward to the boy but Jackson holds his claws out threateningly at him and Isabel.

"You bitch." Stiles mumbles as he collapses to the ground on-top of Derek.

"Get him off me." Derek growls.

"Oh, I don't know, Derek - I think you two make a pretty good pair!" Matt gleefully smiles as he leans into Stiles' ear. "She's mine." He smirks as Stiles angrily glares at him. Matt stands back up. "It must kind of suck, though, to have all that power taken away from you with just a little cut to the back of the neck. I bet you're not used to feeling this helpless."

"Still got some teeth. Why don't you get down here a little closer, huh? We'll see how helpless I am." Derek threatens back.

"Yeah, bitch!" Stiles wheezes out.

The sound of another car pulling up grabs everyone's attention.

"Is that her?" Matt asks, turning back to Scott and Isabel.

Scott closes his eyes as Isabel realises it's his mother. She holds onto his arm comfortingly. Matt narrows his eyes at the interaction. Scott looks down at her, worry in his eyes.

"Do what I tell you to, and I won't hurt her. I won't even let Jackson near her." Matt tells him.

"Scott, don't trust him!" Stiles shouts.

Matt grabs Stiles' shirt and pulls him onto his back. He places his foot onto his throat, pressing down and suffocating him.

Isabel gasps in horror as she watches Stiles and moves forward instinctively. Jackson attempts to slice her neck, but she just looks at him angrily.

"That doesn't work on me." She seethes.
