Dexter, Season 6

Debra:
What you said in there, do you really believe that? You really believe in nothing?

Dexter:
Yeah, I suppose I believe in a certain set of principles.

Debra:
What kind of principles?

Dexter:
A set of rules on how to conduct myself in the world, so that I don't get into trouble.

Debra:
I'm not the most religious person in the world, I mean - Mom practically had to drag me to church, but seriously?

Dexter:
What?

Debra:
A set of rules to follow so you don't get into trouble? Sounds like something I might teach a puppy.

Dexter:
Is that so bad?

Debra:
Just sounds kind of cold and empty.

Dexter:
Does it?

Debra:
Yeah. I don't know - you can believe whatever you wanna believe. Or not believe whatever you wanna believe. But it's not just about you any more. You're a father. What about Harrison? You have to think about what you want him to believe in.

Dexter:
Right.
