Dexter: My life has always felt like an unanswered question... a string of days and nights waiting for something to happen, but I didn't know what. Rita, we're connected. Wherever I am, I feel you, and the kids... with me. You're what makes me real. I want us to always go out for banana splits and replant the lemon tree that keeps dying, and I never ever want to miss a pizza night. And that's how I know I want to marry you. If something as simple as pizza night is the highlight of my week. But not without the kids. Cody, Astor, you guys are my family and I'm gonna hang onto you for dear life. Please, say yes?

Dexter: (voice-over) Role playing; such an important part of growing up. When we were kids whatever role Deb assigned me, evil monster, treacherous Nazi, horrible alien, I played them to perfection.
