He slowly starts to walk back into the hangar, away from the viewport, apparently Yuna doesn't like the sight any more than he does. "Well, I spent most of my time traveling space, with the crew of Serenity. Originally, I was supposed to be going on a mission, like a pilgrimage, but," Book smiles fondly at the ship again, "life has a way of taking you where you need to be, rather than where you think you should be."

Hmm. Pulled out of space and time, but Inara is here, and sick. Maybe...that's what has just happened again?
