Dexter: [voiceover] Not even a year old and you're already destroying evidence. And having to flee the scene of the crime.

Dexter: [voiceover] Rainbows are an illusion, refracted light to make us think there's something there and there's really not. Is there darkness in Harrison or is it just my own fear being reflected back?

Dexter: [voiceover] That's either a saint or the most boring action figure I've ever seen.

Dexter: [voiceover] The babysitter doesn't trust me because of the lies; Lumen doesn't trust me because of the truth. There must be a name for that. Oh, right, Dexter Morgan.

Dexter: [voiceover] We all have something to hide, some dark place inside us we don't want the world to see. So we pretend that everything's okay, wrapping ourselves in rainbows. That's all for the best, because some of these places are darker than others.

Dexter: Are you okay?
Lumen: [Panting, but certain] Yes.

Dexter: Astor showed up drunk on my doorstep with a friend.
Masuka: How old's the friend? [long pause] Just kidding.

Dexter: Harry? [voiceover] Where are you now?, when I really need you. When it´s my wife in a bodybag everybody is looking and it´s the neighbor crying, not me.

Dexter: I remember your first words: shoes. You were very girly once upon a time.
Debra: That's funny. I always remember my first words as being, 'Hurry the fuck up.'

Dexter: I think his little black book has a few blank pages.

Dexter: I'm going to take this gag out of your mouth; but if you make one sound I don't like I'm gonna cut your eyes out. Blink so I know you understand. [Cole blinks, so Dexter removes the gag]. We know about Boyd, and Dan the Dentist, and now you. Who were the others?
Lumen: The guy who held a watch up to my ear? "Tick, tick, tick, that's the sound of your life running out."
Cole: [smirks, but doesn't say anything]
Dexter: [holds a knife to Cole's throat] What are their names?
Cole: [whispers something]
Lumen: What did he say?
Cole: [defiantly] Huey, Dewey, and Louie.
Dexter: [Regags him, and then turns his head to the pictures of his victims] Look at the women, whose lives you destroyed. [Forces Cole's eyes open] Look. Death was the only kindness you showed them. [Dexter slices Cole's cheek and takes a sample of his blood, as Lumen watches with a mixture of fascination and horror. Picks up his knife] It's a shame that you can only die once. [He then looks at Lumen, who nods in approval. Dexter then stabs Cole in the heart. After a long pause] You said I've done this before, that's true. This is who I am. When I was a child my mother was murdered in front of me. It shattered me. I've done this ever since. Because, for the longest time it was the only way that I could feel ... unbroken. And then, Rita was killed, and none of this made sense any more. [Long pause] Until now. [He picks up the blood slide and holds it out to her]
Dexter: [voiceover] Miguel couldn't, my father couldn't, can anyone live with the truth of what I am? [Lumen takes the blood slide] Is Lumen what will make me whole?
[LaGuerta is blaming Debra, instead of herself, for the shootout at the club]

Dexter: I'm just not used to checking the fridge for notes. [voiceover]... just notes from other serial killers.

Dexter: If I can get the crotchety, judgemental babysitter from Ireland to trust me, why not you?

Dexter: It's like when you get on a plane, they tell you if the oxygen masks come down, to put yours on first before taking care of the kids. I need to take care of my own needs, too. Otherwise, I'll be spinning out of control. That's not good for any one.

Dexter: [to Lumen] Don't be sorry your darkness is gone. I'll carry it for you - always. I'll keep it with mine.
