Roy Harper: Is this the part where you kill me 'cause I know your secret?
Oliver Queen: Do you actually think that I'd kill my sister's boyfriend?
Roy Harper: Well, you did shoot me in the leg. Forgiven, by the way.
Oliver Queen: Thea. She can never know.
Roy Harper: I get the feeling that if I did tell her, that would be when you kill me.
Oliver Queen: Trust that instinct.
