Dexter Morgan: I love Halloween. The one time of year when everyone wears a mask... not just me. People think it's fun to pretend you're a monster. Me, I spend my life pretending I'm not. Brother, friend, boyfriend - All part of my costume collection. Some people might call me a fraud. Let's see if it will fit. I prefer to think of myself as a master of disguise.
Dexter Morgan: [voiceover] Everyone hides who they are at least some of the time. Sometimes you bury that part of yourself so deeply you have to be reminded it's even there at all. And sometimes you just want to forget who you are altogether... I'm not the monster he wants me to be so I'm neither man nor beast. I'm something new entirely, with my own set of rules. I'm Dexter. Boo.
Harry Morgan: Being part of a family means smiling for photos.
Young Dexter: Why should I pretend to be happy?
Dexter Morgan: You could take him inside!
Rita's Neighbor: Walther is an outside dog.
Dexter Morgan: You take him inside, he is an inside dog.
Rita's Neighbor: He doesn't like being inside.
Dexter Morgan: He tell you that?
Dexter Morgan: Human bonds always lead to messy complications. Commitment. Sharing. Driving people to the airport.
Angel Batista: I need your expertise, bro.
Dexter Morgan: I live to serve.
Angel Batista: Excuse us, fellas.
[He shows Dexter a severed hand, leaned upright in a beach chair, with a puddle of red blood beneath it]
Dexter Morgan: Interesting hand job.
Angel Batista: [chuckles] That's funny.
Dexter Morgan: [looking confused] It is?
Harry Morgan: It's great to see you're having such a good time, Dex.
Teenage Dexter: You kidding me? This hay is giving me a total allergy attack. We're just going in circles around a pumpkin patch. I don't get it.
Dexter Morgan: "Ox?"
Angel Batista: No. Fuck! What's the matter with you? It's X's and O's.
Dexter Morgan: Like tic-tac-toe?
Angel Batista: Like hugs and kisses! Diamond-filled hugs and kisses in a white gold setting
Dexter Morgan: Well, that's good, because you wouldn't want it to look like someone's playing tic-tac-toe on her head.
Lt. Maria LaGuerta: Do you think Tucci's still alive?
Dexter Morgan: If he is, he won't be for long.
