Teen Wolf, Season 5

Mason:
Corey's not texting me back.

Liam:
Because he left with Theo.

Mason:
[shocked] Are you sure?

Liam:
He was here.

Mason:
Well, then we should do something, right? We should tell someone.

[Liam makes an anxious face when he realizes he's talking about Scott]

Mason:
Liam, you have to tell him.

Liam':
You think he'll even talk to me?

Mason:
You're his Beta. Doesn't he have to?

Liam:
Where would I even start? "Sorry for trying to kill you?" "Sorry for leaving you for dead so that Theo could kill you?"

Mason:
If you start off with sorry, the rest probably won't even matter.
