“You're trying to tell me that everything you've done is for a good cause. You think that all this killing is worth it because of the results. I'm not sure I agree. Lots of people work for charity; lots of people want to change the world. But they don't have to behave like you.”

“I don't know what I'd do without you. There's no one else to look after me. And it's not just that. I sometimes think you're the only person who really knows me. I only feel normal when I'm with you.”
