Bones: I've spent so much time trying to control my life. I thought it meant that I was strong, but I was just afraid.
Booth: Afraid of what?
Bones: I dug out remains from the rubble at the towers. For two weeks, I was methodical. A scientist. I did what was asked of me. I did my job. I never shed a tear. I was proud of that. All these years, I've never let myself deal with it.
Booth: Bones, we all deal with things in our own way.
Bones: I could avoid it all before. I had no one in my life. But now I think of those people, and I think of you. Any one of them, it could've been you.
