Simmons: Then why the hell are you here?
Elias: Well, there remains a debt. Civilization rests on the principle that we treat our criminals better than they treated their victims. That we not stoop to their level. But you and I are outliers. We're not really a part of civilization. We're something... older. Which means, of course, that we can do the things that civilized people can't. I offered to kill you for Detective Carter many times, and she always said no. She was civilized to the very end. I don't think she liked me. But I liked her very much. And you killed her. So now I consider it my responsibility to fix the particular problem that is you, Officer Simmons.
Simmons: You really think you're gonna be the one to kill me?
Elias: No. No, my friend is going to kill you. I'm just gonna watch.
