Scott and Stiles in “Unfinished Business”

Scott

Stiles...?

Stiles

Yes, okay, we followed him out here. What do you want me to say? That I'm a stalker? Huh? That I'm crazy? Totally paranoid? None of this is new information.

Scott

[gently] Now you're gonna try to at least give him the benefit of the doubt?

Stiles

[frustrated] I give people the benefit of the doubt! I've given a lot of benefit to a lot of people.

Scott

Like Derek? ...Kira? ...Liam?

Stiles

I was right about Peter. You know, I bet you still think there's something about him that can be saved.

Scott

[shrugs] Maybe. [He pauses] Why can't you trust anyone?

Stiles

[loses his temper] Because you trust everyone!
