Theo and Stiles in “Unfinished Business”

Theo

Your dad was looking for you, Stiles. He found me instead.

Stiles

Where is he?

Theo

I covered for you. This was taken care of. If Melissa didn't find it at the hospital... Guess even the son of a cop can make mistakes.

Stiles

[angrily] Did you hurt him?

Theo

I never lied about why I came to Beacon Hills. I'm here for a pack. I came for the werecoyote, the one whose first instinct is to kill. I came for the banshee, the girl surrounded by death. I came for the dark kitsune, the Beta with anger issues... I came for Void Stiles! That's the pack I want. Unfortunately, it doesn't include Scott.
