I killed someone, how-- that's not not wrong, either. And I- I can't tell anyone. My dad's the sheriff, he's forced to uphold the law, he'd have to arrest me and I can't- I can't do that to him. And Scott wouldn't understand, he's always against anyone being killed, even if it's the bad guys who're, like, mass murderers, he always wants to save them, too.
[He pauses, drawing breath before he continues, quieter this time.] And I can't... Snow can't know, either. Or David, or Emma.
