Dexter, Season 3

Debra:
Have you started thinking about names yet? Not that I wanna push it on you or anything, but if you have a girl, Debra's a really good name!

Dexter:
...Deb I should tell you-

Debra:
Oh my God what happened!?

Dexter:
Nothing happened! It's just I'm not sure I'm gonna be there to raise the baby.

Debra:
...What?

Dexter:
I don't know if I'm gonna be a father to the kid. [Debra punches him in the arm] Ow!

Debra:
Of course you are you moron.

Dexter:
Deb...

Debra:
Shut the fuck up! How can you even say you're not gonna be a father to that kid! I mean where would you be without Harry!? And he wasn't even your biological father!

Dexter:
I just think I'm gonna be a lousy father, I don't wanna screw the kid up. [Debra punches him in the arm again] Would you please stop doing that!

Debra:
Then stop saying stupid things! I mean first of all who are we kidding, you're gonna be a great father. And second, and much more important big dumb brother of mine, this isn't about you.

Dexter:
...Who's it about?

Debra:
...The baby. So it doesn't matter how scared you are. How reluctant or unprepared you might feel, the baby comes first. And that baby needs you.
