Booth: You know, if it weren't for you, those people would have never known what happened to their daughter. It's gotta be worse than the truth.
Brennan: I know exactly how the Ellers felt about Cleo. My parents disappeared when I was 15 and nobody knows what happened to them.
Booth: Being a sniper, I took a lot of lives. What I'd like to do before I'm done is to try and catch at least that many murderers.
Brennan: Please. You don't think there's some kind of cosmic balance sheet. (Booth looks hurt) I'd like to help you with that.
