Scott and Stiles in “Unfinished Business”

Scott

[about Theo] I don't know why I believed him. I don't know why we didn't just keep talking that night. Five more minutes, and we would've figured out that there were two different stories. We would've filled a lot of blanks. We should've kept talking.

Stiles

He knew we wouldn't.

Scott

I didn't want it to happen like this.

Stiles

Like what?

Scott

I knew, sooner or later, one of us was going to get a little too much blood on our hands. [He laughs nervously] I half-thought it was gonna be Malia.

Stiles

[shrugs] Well, she definitely seems like she's working on it...

Scott

I just always thought that if it were to happen, then it should be me. I'm the one who's constantly putting you guys in danger, risking your lives for people you don't even know. It should've been me.
