- Debra Morgan: If dad taught us one thing, it's the value of human life.
- Dexter Morgan: [voiceover] Yeah, but I think we had different homework assignments.
- Debra Morgan: [sipping her latte] Oh, sweet Mary, mother of fuck, that's good!
- Dexter Morgan: I think you might have broken a commandment somewhere in there.
- Dexter Morgan: [voiceover] Am I the twisted Bay Harbor Butcher, or am I the valiant Dark Defender?
- [thinks about it for a second]
- Dexter Morgan: Nah. Miami's too hot for all that leather.
- Dexter Morgan: See you tonight?
- Debra Morgan: I think I'm staying at Gabriel's.
- Dexter Morgan: I thought you were taking it slow.
- Debra Morgan: We are. No sex, just cuddling.
- Dexter Morgan: My little sister, the cuddler.
- Debra Morgan: I got a scalding-hot beverage here, Dex. Don't make me use it.
- Dexter Morgan: Love you, too.
- Gail Brandon: You think you're charming, don't you? I'm sure that probably works for you most of the time. It did for Paul. I know what you are.
- [begins moving away]
- Dexter Morgan: Confused?
- Special Agent Frank Lundy: You're very fidgety. Anyone ever tell you that?
- Debra Morgan: Yes, my father. You applying for the job?
- Special Agent Frank Lundy: Just an observation.
- [last lines]
- Dexter Morgan: [narrating] Harry taught me to lie, and keep my darkest secrets from those around me. Which why I need to make sure there's not a trace of blood left on my boat. He also taught me not to rush to judgement. Things aren't always what they appear to be - including Harry. And what about me? Am I the twisted Bay Harbor Butcher, or the valiant Dark Defender? Only time will tell.
- Dexter Morgan: Funny thing is, I've met someone who doesn't care what I am. I suppose every hero needs a side-kick. Every villain, a partner in crime? All my relationships have been built on not knowing. But that may be changing. Imagine that, a life with no more secrets.
- Dexter Morgan: [voiceover] Want a real glimpse of the human nature? Stand in the way of someone's mocha latte.
- Dexter Morgan: [voiceover] I never really got the whole superhero thing. But lately, it does seem we have a lot in common: tragic beginnings; secret identities,; part human, part mutant; archenemies.
- Dexter Morgan: [voiceover] The rocks I used to submerge my victims may eventually sink me too, but if I'm learning anything in recovery, it's "one day at a time."
- Debra Morgan: You ran a background check on my boyfriend? What's it say?
- Special Agent Frank Lundy: Gabriel is clean - well, except for those parking tickets.
- Debra Morgan: Just because he's not a criminal, doesn't mean he's not an asshole.
