(voice over) "Darling Rita, once you were a dream and a prayer. Now our future is as bright as the sun glinting off the morning dew. And I vow that I will..." Sounds like I'm marrying a unicorn.

Dexter: Dexter: (voice over) What do I have to offer a child? Just... me. Demented daddy Dexter.

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

(voice over) If home is where the heart is, where do you go when you don't have a heart?

Dexter: What did you say in your bachelor party speech? Friends are always honest.
Miguel: Friends forgive.
Dexter: But, I don't forgive you. And I don't get to have friends.

Miguel: Dex, this is the nature of a real friendship. We're gonna disagree, and when we do, we just go our own ways.
Dexter: No, no more individual projects.
Miguel: Individuality is what makes America great, man.
Dexter: I don't think that's what our forefathers had in mind.

Deb: (About King) Looks harmless, doesn't he?
Dexter: They usually do.
