Dexter Morgan: I've lived in darkness a long time. Over the years my eyes adjusted, until the dark became my world and I could see.

[repeated line]
Dexter Morgan: [thinking] Tonight's the night.

Vince Masuka: The fucking Bay Harbor Butcher is butchering up my online social life!
[Masuka leaves the room]
Dexter Morgan: Sorry.

Dexter Morgan: We have an elephant in the room, and its name is Sex.
Rita Bennett: [laughs weakly] Tell me about it.
Dexter Morgan: Hey, as far as I'm concerned, it can just stay in the corner and mind its own damn business.
Rita Bennett: [softly] Easier said than done.
Dexter Morgan:
Yeah,
[gently brushes her hair back]
Dexter Morgan: but it needs to be right, for both of us, or it won't be right for either of us. I don't want that. Do you?
Rita Bennett: No. You know, I can't believe I found the one good truly decent man left on the planet.

Sergeant James Doakes: [Dexter is about to hit Doakes with a flashlight] Go ahead. Try it. I've been waiting.
Dexter Morgan: This neighborhood?
[shines the flashlight on himself]
Dexter Morgan: It's full of crazies. I'd lock my doors.

Special Agent Frank Lundy: Suit up if you're gonna touch it.
Dexter Morgan: Oh! No, I'm just dropping off some x-rays. I'm Dexter Morgan...
Special Agent Frank Lundy: I know who you are.

Dexter Morgan: So what's up, hot shot?
Debra Morgan: Alright, get this. Lieutenant's looking for that refrigerated truck in every swamp, glade and chop shop from here to the Keys. The way I see it, that whack-job truck driver threw a severed head at your car. It's not as if he's shy.
Dexter Morgan: You think he's hiding the truck in
plain sight, wanting it to be found?
