Teen Wolf, Season 4

Scott:
[about Malia] We need to tell her the truth about Peter. She's going to see the rest of the deadpool eventually.

Stiles:
Try to remember that Peter is the one name missing on that list. Which either makes him incredibly lucky or the Benefactor. If she finds out about him, she's going to go to him. You know she is. And then, he's going to twist his way into her head like he does with everyone, including us. We let him walk around like nothing ever happened, like he's one of the good guys, but Scott, he's not one of the good guys. If she finds out about him, she's gone. That's probably what he's waiting for. And then he wins, we lose.

Scott:
We're already losing.
