Kate didn't just take him back to being a teenager. She took him back to the age when he still knew her. When he still trusted her.

Peter

Can someone in this town stay dead?!

Peter

Scott: This is Malia.
Peter: Beautiful eyes. Did you get them from your father?
Malia: Mother.
Peter: Interesting. Anyway, I'm sure they told you a lot about me.
Malia: The homicidal killing spree came up.
Peter: Well, we're all works in progress.

Sheriff Stilinski: I want you to be honest with me. Totally and completely honest. Have you been time traveling?
Stiles: Hang on, what?
Sheriff: Because if time traveling is real, I'm done, I'm out. You're going to be driving me to Eichen House.
Scott: We found him like that.
Sheriff: Where? Swimming in the fountain of youth?!
Stiles: No. We found him buried in a tomb of wolfsbane in an Azetec temple in Mexico underneath a church in the middle of a town that was destroyed by an earthquake.

Kira: So Kate's a werewolf now.
Scott: I don't know. But there's a saying that sometimes the shape you take reflects the person you are.
Lydia: What kind of shape is sociopathic bitch?

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.

Stiles: Because we don't leave without people, remember? We talked about this. Rules of the wild kingdom don't apply to friends.
Kira: Is that what you would do as a coyote? Leave her for dead?
Malia: If she was weak and injured, yeah. If hunting had been bad that season, I would eat her. Then I'd leave.
Stiles: Believe it or not, that's progress.

Araya: I have to admit, I don't have much experience with banshees.
Lydia: That makes two of us, since I don't have much experience being one.

Just give us Derek. You don't want him anyway. Haven't you noticed what a downer he is? No sense of humor, poor conversationalist. Just come on, take the money.

Stiles

Araya: You brought a wolf into my home?
Stiles: We brought an alpha.

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

Danny: I just don't think I can do it.
Ethan: Do what?
Danny: Date a werewolf.
Ethan: You knew?
Danny: Dude, it's Beacon Hills.

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.
