Rita: Are you an addict?
Dexter: Yes. I have an addiction.

Rita: Deb must be a mess. I mean, falling for a serial killer?
Dexter: What are the odds?

Rita: God created pudding, and then he rested.

Rita: Is it over with Lila?
Dexter: Yes, absolutely, completely over. If I never see her again it will be too soon.

Rita: You might even find I can handle the truth.
Dexter: [voiceover] I wish that was the case.

Roger: Where am I?
Dexter: Looks different under plastic, but you spent an evening here with Anne Cowen. You took her last breath from her right over there, you remember?
Roger: No. Y-you're wrong. I wouldn't!
Dexter: No, you would. And you did. And you were about to do it again; that's why we're here.
Roger: No, this is crazy. You got the wrong guy. I-I sell cars, for God's sake! I'd never hurt anyone in my life � definitely not a woman!
Dexter: ... Why can't I do that?
Roger: Do what?
Dexter: Lie like that! I thought I was good, but you? It's ... mwah.
Roger: I don't lie!
Dexter: Okay, that one was weak.
Roger: Kay, look. Pick any car on the lot. It's yours. T-bird, town car, you name it. Y-yours. Free. I'll call it in right now.
Dexter: Lots closed.
Roger: I'll have them open it up. I'm the manager. They do what I say.
Dexter: The manager's name is Rick Buxton!
Roger: Well, yeah, but I've been there longer than he has.
Dexter: You've been there three months!
Roger: At the other lot.
Dexter: Ha, ha! It's like watching someone ski moguls. You just hop from one lie to the next. No shame, no embarassment. You just don't give a shit. That's the key, right? Not to care about anyone or anything.
Roger: I care. I care a lot.
Dexter: No, it was a compliment. I don't care either.
Roger: Yes, you do. Like about your wife.
Dexter: Not married.
Roger: Girlfriend, then. Saw it the minute you walked on the lot.
Dexter: What did you see? Tell me.
Roger: Look, most guys your age, they'd beeline right for the horse power, or something. Flashy, sexy. But you. You're there all alone, no one there to nag you, and you don't even glance at the coups. The only thing you look at is the mini-van. Like you can see her in the passenger's seat, and the kids in the back.
Dexter: Leave the kids out.
Roger: See? You're lying to yourself if you think you don't care.
Dexter: She's just a companion, really. Started that way, anyway. Someone who ... looks good. Normal.
Roger: They worm their way in.
Dexter: Yeah, they do. And they shut you out.
Roger: ... That's what this is about? That she shut you out? Oh! Man, okay, I get it. I've been there. But you can't let her get to you like this, 'cause � 'cause they're all the same! Fucking bitches! You do everything for them, and then they fuck you! She's not worth it, all right? You're better off without that cunt!
Dexter: [enraged] Don't ...
[Dexter slams his knife into Roger's chest]
Dexter: ... talk that way about my girlfriend!

Rudy/Brian: [while gift-wrapping dismembered parts] Deck the halls with parts of bodies, fa la la la la, la la la la.

Rudy/Brian: Debra Morgan, will you marry me?
Debra: I knew it, I fucking knew it!
Rudy/Brian: Is that your version of a yes?

Rudy/Brian: I just wanted to have a beer with you before we got started. Made that kind of difficult.
Dexter: Sorry.
Rudy/Brian: You don't ever have to apologize to me, Dexter. Not for who you are, or anything you do.

Rudy/Brian: Looks just like it used to, doesn't it?
Dexter: Who does it belong to?
Rudy/Brian: Me. I got it for you, actually.
Dexter: I'm really more an apartment person.

Rudy/Brian: You know the one thing I've been dying to ask you? How did you not know who I was? You're a cop.
Debra: This isn't funny.
Rudy/Brian: I think a real cop would at least have a sense she was in the presence of the person she was hunting.

Rudy/Brian: Your victims. Are they all killers?
Dexter: Yes.
Rudy/Brian: Harry teach you that?
Dexter: He taught me a code. To survive.
Rudy/Brian: Like an ... absurd avenger?
Dexter: That's not why I kill.
Rudy/Brian: You can be yourself around me. Who. Am. I?
Dexter: A killer. Without reason or regret. Free.
Rudy/Brian: You can be that way too.
Dexter: But the code ...
Rudy/Brian: [laughs] Dex! You don't have a code. Harry did. Now he's been dead ten years. You can't keep � keep him sitting on your shoulder like Jiminy Fucking Cricket! You need to embrace who you are now.
Dexter: I don't know who I am.
Rudy/Brian: 'Course you don't. You've been away from your family since you were three. But I'm here now. I can help you. We can take this journey together.
Dexter: I can't. Not Deb ...
Rudy/Brian: No � no, don't say that.
Dexter: I'm very ... fond of her.
Rudy/Brian: You can't be a killer and a hero. It doesn't work that way!

Rudy: I mean, Deb's hot and all, but sprinkle in a little conversation once in a while, you know?
Dexter: Well, she's my sister. I don't know.

Scott Solomon: Meridian? Best thing that's ever happened to me ... so far. How about you? You finding him helpful?
Dexter: I'm a sociopath; there's not much he can do for me.
Scott Solomon: Cute and funny. Let me guess, taken?
Dexter: Girlfriend.
Scott Solomon: Lucky girl.

Sonia: [to Harrison] Can you say "Bye-Bye daddy?"
Harrison: Die-Die.
Sonia: Did you hear that?
Dexter: He said "Die-Die".
Sonia: Don´t be silly. he said "Bye-Bye". Harrison´s first words. He´s a good boy.
Dexter: [voiceover] I hope so.
