Deaton quotes from Teen Wolf

[to Scott on the phone] I honestly thought I would never have to burden you like this, but you're my only hope. I'm going to be taken. I need you to find me.

There's a fox hiding inside a teenage boy... and I'm going to poison it.

Isaac

What are you, some kind of witch?

[sarcastic] No, I'm a veterinarian.

Stiles

I'm just telling you everything you already know, aren't I? Then why aren't you telling us?

Maybe because when you've spent every moment of the last ten years trying to push something away-- denying it, lying about it-- it becomes a pretty powerful habit.

Scott

I don't know what else to do. Do I keep trying to get them to listen to me? Do I tell Derek that he's gonna get them all killed? How do you save someone who doesn't wanna be saved? How do I stop them?

Don't stop them. Lead them.

Your eyes, they were red! Bright red!

Scott

How is that possible?

It's rare, something that doesn't happen within a hundred years. But, every once in a while, a beta can become an alpha without having to steal or take their power. They call it a True Alpha. It's one that rises purely on the strength of character, virtue, by sheer force of will.

Scott

You knew this would happen.

I believed. From the moment I knew you were bitten. I believed

Scott

You weren't the only one

No (Pause as Scott looks on) Deaucalion isn't here for Derek. He's after you.

Essentially, you, Allison, and Stiles need to be surrogate sacrifices for your parents.

Scott

We die for them?

Stiles

But, he can bring us back. [to Deaton] You can... you can bring us back, right?

You remember the part where I said it was dangerous? If it goes right, the three of you will be dead for a few seconds. But, there's something else you need to think about. This is a dangerous thing for more reasons than one. You'll be giving power back to the Nemeton, a place that hasn't had power for a long time. This kind of power is like a magnet-- it attracts the supernatural, the kind of things that a family like the Argents can fill the pages with a bestiary with. It will draw them here, like a beacon. [...] It'll also have an effect on the three of you. You won't be able to see it, but you'll feel it. Every day, for the rest of your lives. It'll be a kind of darkness around your heart. And permanent, like a scar.

You really have to learn, Scott. You really have to learn not to trust a fox. Hmm-mmm. Know why? 'Cause they're tricksters. They'll fool you. They'll fool everyone.

Not everyone.

Scott

Does it say anything?

My Japanese isn't great... but, it appears to say that one method of expelling a nogitsune is to change the body of the host.

Scott

[confused] Change the body?

Which begs the question... how do we change Stiles' body?

Scott

...By turning him into a werewolf.

Peter

[about Nogitsune/Stiles] He doesn't look like he would survive a slap across the face, much less the bite of a werewolf.

Scott

You don't think it would work?

Peter

[shakes head] This is more a war of the mind than the body. There are better methods to winning this battle.

[unsure] What kind of methods?

Peter

We're going to get into his head.

So, do we have a plan?

Peter

Scott is going to try to dig through pale-and-sickly Evil-Stiles' mind to unearth pale-and-sickly Real-Stiles, then guide him back from the depths of his own subconscious. But, he's not going to do it alone.

Scott

What do you mean?

Aiden

[talking about the nogitsune and Lydia] So, no one notices him just kidnapping her right out of the house?

[annoyed] Most of us were concentrated on the bizarre sight of a creature materializing from out of the floor!

[shocked] Wow.

Stiles

Wow? Wow, as in, "I've seen this before, and I know exactly what to do" kind of wow? 'Cause that's the kind of wow we were hoping for.

Scott

I don't want to keep watching people die.

Argent

I'm not sure you have much choice about that.

Scott

Maybe I do.

That's a lot of burden to carry, Scott.

Scott

I don't care. No one else dies. Everyone on that list, everyone on that deadpool... It doesn't matter if they're wendigos, or werewolves, or whatever. I'm gonna save everyone.

How does it begin?

Satomi

With fever. Then, shifting becomes uncontrollable. Fangs, claws, even full, unwarranted transformations. We moved into the woods when that began. Then, it progressed faster and faster. They couldn't stand. But worse than that was this sudden blindness.

[concerned] Total?

Satomi

They couldn't see a thing. From there, they had only a few minutes left.
