Dexter: He lost two brothers, he doesn't know who to blame.
Rita: Certainly not you.
Dexter: (voice over) No, certainly not me.

Lately the thing that surprises me most about Rita is how much I like being with her. But whenever that happens with a woman, when I feel comfortable with her, it all goes wrong. That's why I think it's best to take it one step at a time.

Nothing like some Little Debbies and a worthy new adversary to clear my head.

Dexter Morgan

[talking to young Dexter] Remember this forever, you are my son, you are not alone, and you are loved.

Harry Morgan

(voice over) We're supposed to see hope in children, but right now all I see are little bundles of uncertainty. And germs, but that's another matter. I love kids; I can play with them, enjoy them, and leave. I don't have to worry about what they'll become. A Nobel Prize laureate, a drunk, president of the United States, or someone like me. Why do parents take the chance? I've never felt compelled. But why would I; I'm not in the business of giving life.

Lt. Maria Laguerta: So then he must have already had the head with him in the front seat. Huh, that's weird. Why would he keep it there?
Dexter Morgan: I don't know. So he could use a carpool lane

The FBI estimates that there are less than 50 serial killers active in the United States today. We don't get together at conventions, share trade secrets, or exchange Christmas cards...But sometimes I wonder what it's like for the others. The only sound I hear, the only sound in the entire world....is my heart beating.

Deb: What's going on in there?
LaGuerta: You tell us.
Deb: Why would I know?
Angel: Come on. You're Lundy's pet.
Deb: Fuck you.
Chico: Seriously, what's Lundy got, or is he just blowing smoke?
Deb: Seriously, I don't know. But if he's got something, it ain't smoke. Lundy's too good to blow smoke.
Angel: Man, no wonder you're his pet.
Deb: Fuck you twice.

(voice over, at Cody's presentation) I'm a little confused. Lila is the one showing me how to take control, stop killing, get my life clean. (waves at Cody) But this is the first time since I went into recovery that I actually feel clean.

Sergeant Doakes: You give me the fucking creeps, you know that Dexter?
Dexter Morgan: Yeah, I know, sorry about that.

Doakes: Unlike you, I do everything out in the open.
Dexter: Well in that case, Sergeant, let me put this in the open for you. No matter what you try, no matter when, no matter how hard you work, I'll always be a step ahead of you for one simple reason.
Doakes: And what's that?
Dexter: I own you.

Maria: I don't want you getting into any trouble over this. Use my authorization codes, and make it happen. Procedure above board, results under the table. You good with that?
Dexter: Absolutely. You need something under the table, I'm your guy. (Pause) That didn't come out right.

Dexter Quotes

The only real question I have is why in a building full of cops, all supposedly with a keen insight to the human soul, is Doakes the only one who gets the creep from me.

I think this is a friendly message like, "Hey! wanna play?" and yes I wanna play. I really really do.
