Bones, Season 1

Booth:
You know, I'm sorry for wrecking your weekend for nothing.

Brennan:
No, not for nothing.

Booth:
Ah, you know what I mean. You know all that running around it didn't change anything. Epps was guilty, he was always guilty.

Brennan:
There was doubt. We had an obligation to respect that doubt. We all share in the death of every human being.

Booth:
Very poetic.

Brennan:
No, very literal. We all share DNA. When I look at a bone it's not some artifact that I can separate from myself. It’s a part of a person who got here the same way I did. It should never be easy to take someone's life. I don’t care who it is. [Booth stares at her intently for a long while] What? What? What?

Booth:
You know you've been practicing your Nobel prize speech just a little too much.
