John (referring to Riley): Were you gonna kill her?
Cameron: I don't know what I was going to do.
John: What do you mean you didn't know what you were gonna do? Since when do you not know what you're gonna do?
Cameron: I don't know. I should've killed her. She's a threat to you.
John: That is not your decision to make.
Cameron: It's usually not a decision.
John: Well, obviously it is this time. And it's not yours. What's happening with you?
Cameron: I don't know.
