"Apparently I drugged Derek Hale with a dart and kidnapped him, so he could ressurect his uncle while unconscious. They're having a family reunion in which Derek panics and cries a lot. Peter sent me away."

...

"And this is the same Peter that I've heard such wonderful things about," says Yvette, eerily calm. "Right then. Where is this family reunion occurring?"

"At their house! I'm not sure I can help there. Thinking about him is making everything fuzzy and I don't want to dissociate again so I think I'll stay here."

"Oh, agreed." She still sounds so calm, where is this even coming from. "We're going to keep you far, far away from him." She considers. "Scott, could you please call the Argents?"

"...Stiles, can you call the Argents. I need to sit in the car for a minute." 

Stiles calls the Argents. 

"Am I just explaining the situation and asking for backup?" 

"Yep. Also how best to kill the fucker so that he stays properly dead this time, where he can't mind control anyone else ever again."

"Sounds like a plan. Hey, Mr. Argent? Yeah, Stiles. Friend of werewolves. Peter Hale didn't stay dead and he's kind of awful. Thoughts, suggestions?"

"Is there anything else you can tell us about him?" Yvette asks Lydia. Stiles probably has this covered. The Argents usually have to be convinced to not jump to murder.

"I don't know. He's not good at hiding how little he cares about people, but he still can be charming. He's interested in you after all, and aren't you special? Unless you're warned, or smarter than that." 

"It's not your fault."

"Thanks. I think I might have to blame myself for not saying anything when I started hallucinating, though."

"He said they'll meet us there, but not to bring any other werewolves. Just me, Yvette, and you, Lydia." 

Scott returns, looking a bit like he's been crying.

"We should keep Lydia away from him, he has some kind of control of her. We're not giving him any more power than he already has, especially since we don't know what Lydia is. So you and me."

She looks at Scott, and her face softens.

"Scott, I'm going to make this go away, okay? It will be okay. Promise. He's a bastard, but he hasn't had to deal with me."

"Yeah. I trust you." 

"Okay, let's go meet the people with guns and knives who think they can kill Peter Hale. Scott, keep Lydia company."

"It will be okay," repeats Yvette, and then she gets into the passenger seat to go meet the people with guns and knives.

And they drive.

"Hey, thanks for helping us. These really aren't your problems."

"What would I do, just say, 'Not my problem, have fun with that'?" snorts Yvette. "Not really my style. If I can fix it, I'm going to try." She looks out the window, at the scenery passing by.

He lets her enjoy the view.

Beacon Hills, if nothing else, is teeming with life.

The trees are green again, with the cold creeping away. She can see them starting to blossom.

"I'm not being psychotic with the, the - jumping straight to 'let's put him back where he was' thing with Peter, right. I haven't even met the guy, but from the way everyone talks about him, and the way he mind controls people, and how everyone when mentioning his death thought it was an improvement..."

"Werewolves and hunters tend to think about murder pretty casually. Born werewolves, anyway. Scott thinks about it like a human does, and if you asked him, he would say we find something to contain Peter. Maybe something involving wolfsbane and mountain ash, those are things that weaken werewolves, but. He'll never change. And he's hurt a lot of people. If I thought we could just hold him, maybe."

"I'm not convinced that with the mind control we could," mutters Yvette. "It's - why I jumped aboard the murder train so quickly. There isn't a way to contain someone that will just make other people let him out."
