Brennan and Booth in “The Patriot in Purgatory”

Brennan

I dug out remains from the rubble of the towers. [pauses] For two weeks I was methodical, scientist. I did what was asked of me. I did my job. I never shed a tear. I was proud of that. [tears up] All these years I've never let myself feel... [starts crying]

Booth

[sympathetically] Bones, we all deal with things in our own way, ok?

Brennan

I could avoid it all before I met you. I had no one in my life. And now I think of those people and I think of you. Any one of them, it could've been you. [Booth embraces her as she sobs into his chest]
