Dexter: Are you hoping they'll talk to you?
Lundy: The one's with heads anyway. They always speak, eventually. Just gotta ask the right question.
Dexter: Which is?
Lundy: Why were they chosen?
Dexter: You looking for a pattern?
Lundy: One doesn't kill this many people in this careful, methodical way without a reason. Some ... twisted set of principles.
Dexter: They would have to be twisted, wouldn't they?
Lundy: The worst killers in history are usually the one's who think the murders were somehow ... just. Even deserved. Leaders have slaughtered whole populations for the same warped reason.
Dexter: But there's never any justification for killing.
Lundy: No. Well, one, of course. To save an innocent life.
Dexter: To save an innocent life.

Dexter: Come on, don't get the shakes now. This is no time for performance anxiety.

Dexter: Deb, Doakes is a lot of things, but he's not an idiot. He won't come out of the shadows because of a grudge.
Debra: Right. 'Cause serial killers are so practical.
Dexter: Actually, they are.

Dexter: DNA, DNA, come out and play.

Dexter: Doakes thinks he knows my secrets. But he only needs to look at this � my body of work � to know the real me.

Dexter: Don't test me, Sergeant. I could have killed you. I didn't.
Doakes: You didn't because you can't. I've had time to think about this, Morgan. I don't fit that code you were talking about, do I? At first I thought the Butcher only went after criminals because nobody gives a God damn what happens to them. But now ... now I think you got a conscience.
Dexter: Of course I have a conscience. I left you a place to shit, didn't I? It's a small conscience.

Dexter: For the first time, I feel that the future might hold something different for me. It's possible I'm just fooling myself, but I'm willing to take the risk.

Dexter: Hey, Sergeant. Thanks for supporting the bowling team.
Doakes: Fuck you.

Dexter: Hold the elevator!
[Dexter gets his arm into the elevator doors as they close. The elevator opens and he enters. Doakes is in there]
Dexter: Thanks.
Doakes: Nice dodge last night, flooring it through that yellow light.
Dexter: Oh. Were you behind me?
Doakes: See you tonight.

Dexter: How many more bodies would there have been had I not got to those killers? I didn't want to save lives, but save lives I did. Motivation aside, I think Harry and Lundy would agree on this one.

Dexter: I can't afford to lose it. Not with Special Agent Rock Star on my case.

Dexter: I come here to dump bodies, not beer bottles. Now I'm just a litter bug.

Dexter: I feel like a jigsaw puzzle missing a piece. And I'm not even sure what the picture should be.

Dexter: I go to stalk a killer, and I end up with a new car. How'd that happen?

Dexter: I have to focus. Tune everything out. If I don't, being linked to my beautiful bodies of work will be the least of my worries.
