- Travis Marshall: You're gonna burn in hell.
- Dexter Morgan: No. I think I belong right here. Because maybe there is a place for me in this world. Just as I am. Light cannot exist without darkness. Each has it purpose. And if there's a purpose to my darkness, maybe it's to bring some balance to the world. Because let's face it, the world is going to be a better place without you.
- Dexter Morgan: [narrating] One thing I'm sure I have faith in is the staying power of animal tranquilizers.
- Dexter Morgan: [injecting Travis] Is that my shirt?

- Travis Marshall: This is not how it's supposed to be!
- Dexter Morgan: Maybe this is exactly how it's supposed to be. Maybe everything is exactly how it should be.

- Dexter Morgan: [narrating] I guess it's fitting I end up where I've left so many others. I only wonder if the world will be a better place without me. It's wrong what people say about dying. I'm not flashing back over my life - over the lives I've taken. I'm thinking about the life I'll miss. Harrison, I'll miss watching my son grow up.
- Dexter Morgan: I known people who believe in God. They never use as excuse their faith to kill ten people. You used God. It's not the other way around.
