Doakes: What does that girlfriend of yours see in a freak show like you anyway?
Dexter: You'll have to ask her.
Doakes: Maybe I will.

Doakes: You finally decided to fight back. I've been waiting.
Dexter: I hope you don't expect me to comment on that so you can record it on your hidden tape recorder. I wasn't born yesterday.
Doakes: You might have been, for hell I know. Your past is a bigger mystery than fucking Jimmy Hoffa. I tried every avenue, legal and otherwise, but there ain't no paper trail on the early years of Dexter Morgan.
Dexter: I guess there's no recorder running after all.
Doakes: No, man. 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 always be a step ahead of you for one simple reason.
Doakes: And what's that?
Dexter: I own you.

Doakes: You got it wrong, man. I left her.
Curtis: And why was that?
Doakes: Because I was afraid that if I didn't, I'd kill her.

Doakes: You just found out that somebody who's supposed to be your friend is going to live. Does that make you feel anything? Anything at all? [grabbing Dexter's shoulder]
Dexter: Take your fucking hand off me.
[Cold silence]
Doakes: Just what I always thought.

Doakes: You're not gonna do what I think you are.
Dexter: There's no point in hiding it now, Sergeant. Your life is going to rest in the hands of the criminal justice system you put all your faith in. I wish you the best of luck.

Ellen Wolf: We all know how easy it is to plant evidence, and let's be honest, you look the type.
Dexter: [voiceover] Do I see sheets of plastic in your future?

Fowler: Who are you?
Dexter: Just a fellow traveler who also likes to pick up dead animals.

Frank Lundy: What exactly is Sergeant Doakes' problem with you, Morgan?
Dexter: [voiceover] I kill people, for one.

Gail: And I see a young man who is not eating.
Cody: I'm not hungry.
Astor: He's scared the Butcher's gonna get him.
Dexter: Remember, he only gets bad people.
Cody: I was bad today. I threw a ball at Tommy Albertez.
Dexter: Well, that's not too bad. And even if it was, the Bay Harbor Butcher doesn't hurt kids.
Cody: He doesn't?
Dexter: Nah. You're safe.
Rita: When are they gonna hurry up and catch this guy?
Dexter: They're working as hard as they can.
Gail: Well, if what I've heard is true, that he only goes after criminals, I say leave him alone. He's got my seal of approval.
Dexter: [thoughts] Perhaps I have misjudged you, oh wise one.

Harry Morgan: Keeping the truth from the people closest to you is how you'll survive, and how you'll protect them if anything goes wrong.

Harry Morgan: Never underestimate the capacity of other people to let you down.

Harry Morgan: No matter how close two people are, an infinite distance separates them.

Harry Morgan: We only see two things in people: what we want to see and what they want to show us.

Harry Morgan: When you take a man's life, you're not just killing him. You're snuffing out all the things that he might become. As a cop, I only fire my weapon to save a life � that's a code I live by. Killing must serve a purpose. Otherwise, it's just plain murder.

Harry Morgan: You're here. Rita's back home. You're cheating on her and you don't even realize it.
Dexter: I'll make time for my Dark Passenger and for Rita.
Harry Morgan: It's about priorities, Dexter. You're going to have to choose which one is your mistress and which one is your wife, and more importantly, which one comes first.
