Derek quotes from Teen Wolf

Scott

They're trying to help.

Derek

[incredulously] These two? [He points to Lydia] This one, who used me to resurrect my psychotic uncle, thank you. [He points to Allison] And this one, who shot about thirty arrows into me and my pack.

Stiles

Okay, all right, now. Come on, no one died, alright? Look, there may have been some maiming, okay? A little mangling, but no death! That's what I call an important distinction.

Scott

Derek, I saw Boyd try to rip two little kids apart. Are they going to do that to everyone they find?

Derek

Everyone and anyone.

Scott

We need help.

Derek

We have Isaac now.

Scott

I mean real help.

Derek

Cora's alive.

Peter

So I heard! Let's throw the reunion party when she's not an unstoppable killing machine.

Jennifer

What do you want? You gonna threaten me? Tell me that no one's gonna believe me? Try to scare me? ...Kill me?

Derek

[laughs] I was gonna see if you were okay.

Jennifer

Physically or emotionally? Although, I guess that presupposes I was emotionally okay before any of this, and according to my therapist, I... it's been debatable for a long time.

Cora

I can't believe I got my ass thrown in a vault for three months for you. All those rumors I heard. A powerful new Alpha. One of the Hales, building a pack! Do you know how long I've waited to hear something like that? Do you have any idea how it felt to find out you were alive?

Derek

I'm sorry to disappoint you.

Derek

[spits out blood] What do you want? You want to kill me?

Deucalion

You really think I'm that boring? Don't throw me in with sociopaths like your uncle! I'm a man with far more vision than simple murder. In fact... I'm here to show you just how much vision a blind man can have.

Derek

I know what you are. You're a fanatic.

Deucalion

Know me? You've never seen anything like me! I am the Alpha of Alphas. I am the apex of apex predators! I am Death, Destroyer of Worlds! I am the Demon Wolf! [Thunder rumbles outside, and his voice is so loud his sunglasses crack. Afterward, he sighs] Hate it when that happens.

Cut off the head of the snake, and the body dies.

Peter

Only this isn't a snake, it's a Hydra. And, like Scott said, they're all Alphas.

Derek

Deucalion's still the leader.

Peter

Let's hope so, because, do you remember what happened when Hercules cut off of the the heads of the Hydra?

Scott

[sighs] ...Two more grew back in its place.

Peter

[smirks] Somebody's been doing their summer reading!

Derek

How bad?

To be honest, the "Oh, my God" would be for your wonderful physique, if not for the fact that you're bleeding black blood.

Derek

Go back to school.

Isaac

Well, actually, we can't-- Boyd and I are incredibly sick.

Derek

With what, brain damage?

Isaac

Well, I have a migraine, and, uh, Boyd here has explosive diarrhea.

We're here to protect you.

Derek

You're here to protect me? Well, I'm in trouble, then.

Kali

Gonna be honest, Derek-- when Ennis died, I thought to myself, "I'll just go for it." Find you and kill you, wherever you stood. Then, I remembered how you surround yourself with these teenagers, hiding behind them. And, I thought, "What's a girl gotta do to get you alone?" [She has the twins bring out Jennifer, who they've taken hostage] You and me, Derek, or they tear her apart. What do you say? You think you can beat me one-on-one?

Derek

I'm gonna rip your throat out. With my teeth.

Derek

You killed innocent people.

Jennifer

So have you. I know the real color of your eyes, Derek, and I know what it means. I'm not asking you to save just my life. I'm asking you to save everyone they'll ever hurt again.

Derek

[defeated] You can't beat them.

Jennifer

Are you sure about that? Boyd asked you right before he died, "What happens to a werewolf during a lunar eclipse?" You didn't get the chance to tell him, but you know, don't you? What happens, Derek? During the total lunar eclipse?

Derek

We lose all our power.

Isaac

Want to figure something out? Because while Scott and Stiles were out there trying to help people from being killed, you were in here, rolling around the sheets with the actual killer! Do you get how many people she's killed? Erica and Boyd are dead, Cora is dying, and you're doing nothing! Why did you do this to us Derek? Was it all about the power? Were you bored? Were you lonely?

Derek

Maybe. [Isaac angrily goes to leave] I told Cora I wouldn't leave. I'll help the others when I figure out how to help her.

Isaac

There's no time! The full moon's coming. The sheriff and Melissa are going to be dead, so I'm going to help them. You can sit here and perfect the art of doing nothing.
