Person of Interest, Season 3

Alonzo Quinn:
Loyalty. That's why Simmons came after you and Carter. Loyalty. That's how we built this whole damn thing. I'll be damned if I repay that loyalty by breaking it now. Even if you threaten to kill me.

John Reese:
You see? That's why you and I understand each other. Now, everything you do is an abomination. But your word...your word is your bond. To your godson. To Carter. You do what you say. So do I. I'm not gonna threaten to kill you. I'm going to kill you whether you tell me or not. No bargaining. In three minutes you're dead. I've killed many people. Never bothered me much. That's why I was good at it. I didn't like them suffering, though. Took me years to figure out how to do it quickly, painlessly. But if you don't tell me, I'm gonna forget all of that. Understand? And I'll make the last three minutes of your life last forever.
