Not that I'm trying to convince you because the sight of blood excites me or anything, but I just want to let you know that if you choose to kill him and he chooses not to kill you, you will assuredly win. We'll make sure of that.

But if you trust him, and he trusts you, you both survive the night.

Saaaadly, I think I know what you're going to say, but one more time for posterity - would you like to kill your partner?
