Angel: Did you take Harrison for his preschool interview?
Dexter: Yeah, I did.
Angel: Good, because Audi really liked it there.
Dexter: She didn't find it scary? The statues, and the, you know.
Angel: The crucifix. That's a very powerful image of the sacrifice that was made for us. All kids have to learn those kinds of things.
Dexter: [voiceover] Those kinds of things. [aloud] Sorry, but why?

Brian Moser: Hey, little brother. Miss me?

Deb: You were right. I told him. I fucking told my brother that I love him and he said I love you back. Not me too, or something like that. He actually said I love you.
Dr. Ross: Wow. It's big, isn't it?
Deb: Yeah, I don't think he understood that I'm actually in love with him, but he still said the actual words for the first time.
Dr. Ross: So what do you think it means?
Deb: I don't know what the fuck it means. That's why I'm here. Is this is just horribly wrong?
Dr. Ross: Does it feel wrong?
Deb: It makes my whole life -- every man I've ever loved makes sense. It's like I've always been looking for someone like Dexter, or someone who's the opposite of Dexter, as a way to avoid the fact that I'm in love with him. It's just clear to me. I want it to be clear to him. I want him to understand.

Debra: What you said in there, do you really believe that? Do you really believe in nothing?
Dexter: Well, I suppose I believe in a certain set of principles.
Debra: What kind of principles?
Dexter: Well, a set of rules on how to conduct myself in the world so I don't get into trouble.

Debra: You can believe whatever you want to believe - or not believe whatever you want to believe but it's not just about you anymore. You're a father. What about Harrison? you have to think about what you want him to believe.

Dexter: [voiceover] Fast reflexes. I hate jocks.
[Joe is on Dexter's table]

Dexter: [voiceover] Life is good. I'm not at all unhappy - I'm quite content to go about my life believing in nothing, with no fear that there might be something more out there.... But I also have a son, and I also have to think about what he wants, and what's best for him, because who knows? Maybe he'll grow up to be someone who wants to think about...those kinds of things.

Dexter: [voiceover] There are times in our lives when everything seems to go wrong. When despite our best efforts, and for no apparent rhyme or reason, tragedy strikes.... And there are other times when everything goes just perfectly. That's how the last year has been for me.

Dexter: [voiceover] We all want life to have some kind of meaning. Seems the older we get, the harder we look for it. And the harder it is to find. And some of us just look in the wrong place. But if our lives don't have meaning, what can we leave behind for those we care about?

Dexter: A father, a son, a serial killer.
(Debra see Dexter kill Travis)

Dexter: High school. A small world onto itself, combining all the warmest elements of a federal work camp with those of a third world poultry farm. It's a miracle I graduated without killing anyone.

Dexter: I have no idea what Hammer time is. Or how it differs from regular time.

Dexter: I was drawn to science out of curiosity. Any questions I had, the answers were already there, but even science is never certain, even the soundest of theories is subject to new data. And there are some things even science can't explain. Brother Sam would say it's not an accident that I've stumbled onto a killer that seems to have his own kind of faith. And while I don't believe in an unseen hand creating his own tableau, I do believe I don't have all the answers.

Dexter: I've learned that periods of darkness can overcome us at any time. But I've also found that I'm able to endure, overcome, and in the process grown stronger. Smarter. Better. All is well in my little corner of the world.

Dexter: Rituals are important. Not only for a serial killer, but also for a two-year-old if you want him to go to bed on time. Not that I mind. This ritual has become my favorite. Bedtime, alone with my son. Being myself.
