Dexter: What would Jesus have done? Seriously now. How do you reconcile your belief in a higher power, in a God, with what you've done?

Joe: Look - I - I - I mean - everyone makes mistakes. Th-they do things they shouldn't do and - they're only human but God - God forgives us.

Harry Morgan: How's it feel?

Harry Morgan: C'mon, it's great. Most of the people here would love to be popular.
Dexter: Most people don't have two rolls of duct tape, eighty yards of plastic sheeting and a surgical saw in their trunk.

Debra: Why?
Quinn: What's the big deal?
Debra: That's what I'm asking you. You're being weird.
Quinn: You're being weird.
Debra: Okay, now you're being weird and stupid.
