Person of Interest Season 1 Episode 3

Reese: Hey, Finch, I just got the call. Gang's picking me up. I get told the target en route.
Finch: You're not going in with them?
Reese: I got to watch Joey's back. I don't trust his friend Straub one bit.
Finch: I did not understand "infiltrate the gang" to mean "join them in their robbery."

Jessica: I waited for you.
Reese: I didn't ask you to.
Jessica: No. No, you didn't. You just left because you thought you'd get killed over there and that would hurt me. But I think the truth is that it was easier for you to be alone.
Reese: That's one of the things you learn over there. In the end we're all alone and no one's coming to save you.

Finch: (revealing the criteria used to identify persons of interest) I built the Machine to look for lethal intent... armed robbery wouldn't normally make the cut.

Reese: Good morning, Finch.
Finch: Don't you knock?
Reese: Not if I can help it.

Finch: Do we even know why he's such a mess? He's got a job, pretty girlfriend, good service record--he's throwing it all away. He's going to end up in prison. Or dead.
Reese: You're right, but... not every ex-soldier meets a reclusive billionaire.

Carter: I keep looking for you. I keep finding myself in some bad situations.
Reese: You could always stop looking for me.
Carter: Not an option. Now I've got two more bodies. I don't think you killed those guys. But I think you know who did.
Reese: I'll take care of it.
Carter: Playing a dangerous game. And I'm not sure I understand why.
Reese: I've got my reasons.
Carter: Maybe you do. But every killer I locked up thought they had a good reason. And that is how this ends. Sooner or later, I lock you up. Or find you bleeding out somewhere.
Reese: I will take my chances.
