Teen Wolf, Season 5

Theo:
If Scott really gave up on you for some piece of crap like Donovan, then he wouldn't be a True Alpha, would he?

Stiles:
Or maybe that's the definition of one-- someone who doesn't put up with murder.

Theo:
[rolls his eyes] It sounds like you guys need to look up "justifiable homicide."

Stiles:
[side-eyes him] Did you seriously just say that to the son of a cop?

Theo:
A werewolf's eyes are supposed to change color when you take an innocent life. [He flashes his gold eyes to Stiles] Do these look blue to you? It was self-defense-- for me and you.

Stiles:
Or maybe you just don't feel all that bad about it. You can't say that one life is objectively less innocent than another one. What if they turn blue 'cause you feel guilty?

Theo:
So it's up for interpretation?

Stiles:
Yeah, maybe.

Theo:
Then here's my interpretation of what happened with you and Donovan: Not guilty.
