Lt. Debra Morgan: Appealing to Dexter over the phone: "Where in Fucktopia are you?"
Dexter Morgan: [voiceover] I've been lost before; after Rita died, after Lumen left. But now I've been... found. Brian Moser, my dead brother. It's been a long time since I've seen him.
Rudy Cooper: Too long.
[tossing a body bag to Dexter]
Rudy Cooper: Here, catch. You used to love to play, why the long face?
Dexter Morgan: Brother Sam had hoped I'd be able to forgive Nick for shooting him.
Rudy Cooper: Because you don't turn the other cheek, you slice it. Brother Sam doesn't know you like brother Brian does.
Prof. James Gellar: God is the one with choice, Travis. He chose you and me. We, however, have no say.
Travis Marshall: What about free will?
Prof. James Gellar: Oh, please.
Brian Moser: Look at your life. Sippy cups, poopy diapers, baby monitors. You've been domesticated!
Dexter Morgan: I couldn't believe it.
Jonah Mitchell: Couldn't believe what, that I turned into a killer like my father?
Dexter Morgan: Yes, I thought I set you free; set your whole family free.
Jonah Mitchell: I wanted to kill him myself.
Dexter Morgan: But you'll settle for killing your mom and your sister?
Jonah Mitchell: Yeah, and you...
Dexter Morgan: [narrating] Brother Sam believed light can keep darkness at bay. But I wonder if darkness is defined by light. If so, darkness can't exist on its own. There must, by definition, be light somewhere, waiting to be found.
Harry Morgan: [appearing on the side of the road hitchhiking] Welcome home, son.
