Dexter, Season 1

Rudy/Brian:
Your victims. Are they all killers?

Dexter:
Yes.

Rudy/Brian:
Harry teach you that?

Dexter:
He taught me a code. To survive.

Rudy/Brian:
Like an … absurd avenger?

Dexter:
That's not why I kill.

Rudy/Brian:
You can be yourself around me. Who. Am. I?

Dexter:
A killer. Without reason or regret. Free.

Rudy/Brian:
You can be that way too.

Dexter:
But the code …

Rudy/Brian:
[laughs] Dex! You don't have a code. Harry did. Now he's been dead ten years. You can't keep - keep him sitting on your shoulder like Jiminy F***ing Cricket! You need to embrace who you are now.

Dexter:
I don't know who I am.

Rudy/Brian:
'Course you don't. You've been away from your family since you were three. But I'm here now. I can help you. We can take this journey together.

Dexter:
I can't. Not Deb …

Rudy/Brian:
No - no, don't say that.

Dexter:
I'm very … fond of her.

Rudy/Brian:
You can't be a killer and a hero. It doesn't work that way!
