Person of Interest Season 2 Episode 4

George: He was a degenerate gambler, and it got him killed. You had better learn to accept that, Annie.
Annie: I do. But I also remember that Sean was the sweetest guy in the world until the day he started working for you. So degenerate or not, I'll always miss him. I wonder who's gonna miss you when you're gone, George?

Reese: Are you saying we should protect Annie but not Riley?
Finch: I'm just saying you might not want to put yourself and her at risk for a man like that. He's a killer, Mr. Reese.
Reese: So was I, Finch.
Finch: I think there's a distinction to be made.
Reese: Not as much as you think.

Carter: Detective Szymanski. It's good to see you back on active duty.
Szymanski: You know, I thought about dying but realized I couldn't afford it on a detective's salary.

Riley: You've got a detective in your pocket?
Reese: More like on my back.

Reese: Earlier, what did you mean when you said "bad code"?
Finch: It means a flawed design. The term applies to machines, not people. We have the ability to change, evolve.
Reese: Even killers.
