- Scott McCall: How do we know it's not her?
- Stiles: Because I looked into the eyes of that thing, OK? And what I saw was pure evil. When I look into Lydia's eyes, I only see 50 percent evil. Alright, maybe 60. But no more than 40 on a good day!
- Sheriff Stilinski: Not exactly? Or no? Because when it comes to law, there's a fairly large divide between 'not exactly' and 'no.' Like if 'not exactly' were sitting in this chair, then 'no' would be somewhere in the middle of the Pacific Ocean drowning next to my career!
- Coach Finstock: Tomorrow's midterm is so profoundly difficult, I'm not even too sure I could pass it.
- Scott McCall: Lydia's different!
- Derek Hale: I know. At night, she turns into a homicidal, walking snake.
- Stiles: [When Lydia gives him a weird look for double-locking the door] Ah... There's been a few break-ins around the neighborhood... And a murder!
- Coach Finstock: Why don't you tell your buddy, Danny, to take care of his equipment. Or I'm gonna make you take care of his equipment for him! And do you really want to be taking care of Danny's equipment all the time?
- Scott McCall: That depends. Are we still talking about lacrosse pads?
- Coach Finstock: You know there are certain responsibilities to being the captain of the lacrosse team...
- Scott McCall: Co-captain.
- Coach Finstock: OK, partial responsibilities.
- Erica: This may make me sound like a bitch, but I've always wondered what it would feel like to steal someone else's boyfriend. I bet it's a pretty sick rush of power.
- Stiles Stilinski: If you harm one perfect strawberry-blonde hair on her head, I'm gonna turn your little Werewolf ass into a fur coat and give it to her as a birthday present.
- Adrian Harris: Einstein once said, "Two things are infinite: the universe and human stupidity and I'm not sure about the universe." I myself have encountered infinite stupidity. So to combat the plague of ignorance in my class, you're going to combine efforts through a round of group experiments! Let's see if two heads are indeed better than one. Or in Stilinski's case, less than one.
