Dexter, Season 6

Walter:
I took teeth. You take blood. You're the same kind of sick f***, aren't you?

Dexter:
At least I'm never gonna end up like you.

Walter:
Yeah? When you can't do this any more, what do you have then?

Dexter:
More.

Walter:
You're kidding yourself, asshole. All I ever cared about was killing, and I can't even do that right any more. That's what you've got to look forward to. This is your future, and it includes adult f***ing diapers!

Dexter:
You are not my future. I will not spend my final days getting drunk and staring at a box of trophies.

Walter:
Keep telling yourself that. Make sure they know who I am. I wish I could see the look on my son's face when he finds out. He won't be able to ignore that!

Dexter:
I'd never want my son to find out who I was.

Walter:
You said you didn't have a kid.

Dexter:
I also said my name was Dan.
