Brennan and Booth in “The End in the End”

Brennan

If the thing that made me me is gone who am I?

Booth

You're the woman I love. You're the one who kissed me outside of a pool house when it was pouring rain. You took me to shoot Tommy guns on Valentine's Day. That's who you are. You're the one who proposed to me with a stick of beef jerky in her hand, even though you're a vegetarian. You're the Roxie to my Tony, and the Wanda to my Buck. Who else is gonna sing "Hot Blooded" with me? Hmm? And besides we're way better than Mulder and Scully.

Brennan

I don't know what that means.

Booth

I don't care if you know about the bones or if we know how to solve crimes. All I know is that I want to spend the rest of my life with you. This is you. Temperance Brennan. You. You're my partner. Don't forget that.
