Wash, on the other hand, has tuned the noise out. When the the soundtrack of your life is the humming of a spaceship or the constant chatter of someone with a low IQ and a lot of feelings, you get used to noise fairly quickly. (Conversely, it's the silences that get eerie, but Wash has never been one for complete quiet to begin with.)

He's caught a blip on his motion tracker, and he's following closely enough to keep them in earshot but far enough away not to attract attention. He can hope he's following a Legionnaire; worst case scenario, it's something out to kill him. Again.

Whatever it is, it's around a corner, and right now Wash is trying to decide whether the potential benefits of turning that corner and revealing himself outweigh the risks.
