Booth and Brennan in “The Sense in the Sacrifice”

Booth

[seriously] Look, we gotta make a deal and this deal has got to stick, all right? From now, I will do all the fighting and the shooting and the apprehending of killers, ok? You can do all the smart stuff, right? Stay in the lab, play with your bones...and all that good stuff. You know, I don't come to your lab there and play with your telescopes––

Brennan

I don't have a telescope.... [turns and looks at Booth, concerned] What's wrong?

Booth

[swallows] Look, the main reason I wanted to kill Pelant is because he kept me from marrying you.

Brennan

I thought it was something like that.

Booth

And if I told you why we couldn't get married he was gonna kill innocent people.

Brennan

You made the right choice. It's alright. [He smiles and takes her hands in his]

Booth

Bones, If I ask you to marry me, will you say yes?

Brennan

If I say yes will we get married?

Booth

Yes. [They smile at each other before kissing]
