Booth: Do you remember the last time we were here? Standing right around in this spot? It was right in the beginning , before we really knew each other. I was trying to get away from you because, um, you were irritating me. And, uh, you chased me down an you caught up to me. I just have to get all my ducks in a row and then you said to me... Brennan: I can be a duck! Booth: Yeah. We have been chasing each other for a long time. We've been chasing each other though wars, and serial killers, ghosts, and snakes. Chasing you has been the smartest thing I've ever done in my life. An being chased by you has been my greatest joy. But now we don't have to chase each other because we caught each other.
