Ducky's wisdom for Bishop.
Ducky: I think I hear my pillow calling. Unless, of course, you'd like to talk about the real reason you're down here?
Bishop: A suspect got away because of me. I completely screwed up, Ducky. And I went to Gibbs to explain but he said it was fine. Which, I know it's not. And...
Ducky: Eleanor, when the world overwhelms I find the best thing to do is to start by accomplishing just one little thing.
Bishop: I really don't think I can do that anymore.
Ducky: If you actually believe that - why are you sitting on the frigid floor, in the middle of the night?
