Kate: You're... you were dead.
Derek: No. I was evolving. Something you'll never do.

Derek: It's a mortal wound and right now I'm feeling pretty mortal.
Braeden: I am not going to let you die.

Scott: Where's your money?
Derek: You're standing on it.
Scott: There's another vault?!
Derek: [laughs] I own the building.

Ya know anabolic steroids are illegal in the United States. You got an awful lot of facial hair for a teenager. Seriously. What are you on?

Stiles

Scott: What are you smiling about?
Derek: You're gonna be good at this.

Stiles: Derek, if this is only just a dream, then why are you so worried?
Derek: Because I don't remember waking up.

Aiden: Does it hurt you as much as it hurts me?
Ethan: Yeah.
Aiden: It's OK. Lydia never believed I was one of the good guys anyway.
Derek: She'll believe me.

Nogitsune: I've heard of an Alpha pack, Derek, but not a pack of former Alphas. It's a little sad, isn't it?
Derek: I might not be an Alpha, but I can still fight like one.

Scott's always been about one thing. Saving his friends. He will do anything and everything to save the people he cares about. When there's no chance of winning, he keeps fighting. When all hope is lost, he finds another way and when he's beaten down he stands up again! You want to find a place in his pack? You want redemption? Find another way to stand and fight!

Argent: So, I don't suppose you have any idea why Stiles would frame us for murder?
Derek: I didn't think Stiles was smart enough to frame us for murder.

Kira: You're going to tell Scott that Barrow might have used foxfire created by me to jump start the Nogitsune's power inside Stiles. Basically that I helped the dark spirit take control his best friend.
Derek: You should probably wait here.

Aiden: I kinda overheard... well I listened in on Stiles talkin' to Scott about how he thinks he was the one that wrote that message to kill Kira.
Derek: You think Stiles, skinny defenseless Stiles, is the Nogitsune, a powerful, dark spirit.

Teen Wolf Quotes

I have a son. His name is Mieczyslaw Stilinski, but we call him Stiles. I remember. When Stiles was a little kid, he couldn't say his first name. I'm not sure why, it pretty much rolls off the tongue, but the closest he could was mischief. His mother called him that until...I remember when Stiles first got his jeep. It belonged to his mother. She wanted him to have it. The first time he took a spin behind the wheel, he went straight into a ditch. I gave him his first roll of duct tape that day. He was always getting into trouble, but he always had a good heart, always. We're here tonight because my goofball son because he decided to drag Scott, his greatest friend in the world, into the woods to see a dead body.

Malia: Alright. I'll ask. Who's Kate Argent?
Kira: [raising hand] Uh, I'd like to know, too.
Stiles: Well, we were at her funeral, so I'd like to know how she got out from a casket buried six feet under ground.
