I don't care if you know about the bones or if we know how to solve crimes, all I know is...
Brennan: If the thing that made me me is gone, who am I?
Booth: You're the woman I love. You're the woman who kissed me outside a pool house when it was pouring rain, 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 your hand, even though you're a vegetarian. You're the Roxy to my Tony and the Wanda to my Buck. Who else is going to sing Hot Blooded with me? And besides, we are 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.
