Bones, Season 5

Booth:
I'm a gambler. [Brennan gives him a quizzical look] I believe in giving this a chance. Look, I wanna give this a shot.

Brennan:
You mean us? [Booth nods] No, the FBI won't let us work together --

Booth:
Don't do that, that is no reason -- [he kisses her, but after a moment she pushes him away]

Brennan:
[close to tears] No! No!

Booth:
[desperately] Why? Why?

Brennan:
You -- you thought you were protecting me, but you're the one who needs protecting.

Booth:
Protecting? From what?

Brennan:
From me. I -- I don't have your kind of open heart.

Booth:
Just -- just give it a chance, that's all I'm asking!

Brennan:
No, you said it yourself: the definition of insanity is doing the same thing over and over again and expecting a different outcome.

Booth:
Well, then let's go for a different outcome, here! All right, let's just hear me out, right? You know when you talk to older couples who, you know, have been in love for thirty or forty or fifty years, all right? It's always the guy who says, "I knew." I knew, right from the beginning.

Brennan:
Your evidence is anecdotal.

Booth:
I'm that guy. Bones, I'm that guy! I know.

Brennan:
[crying] I -- I am not a gambler. I'm a scientist. I can't change! I don't know how. I don't know how. [Booth looks crushed] Please don't look so sad.

Booth:
All right, okay. [sighs, then hangs his head.] You're right. You're right.

Brennan:
Can we still work together?

Booth:
[Booth hesitates, Brennan gives him a pleading look] Yeah. [wipes away a tear]

Brennan:
Thank you.

Booth:
But I gotta move on. You know, I gotta find someone who's -- who's gonna love me in -- in thirty years, or forty or fifty.

Brennan:
I know.
