Tristan: Don't you ever sleep?
Yvaine: Not at night. May have escaped your notice, genius, but that's when the stars have rather better things to do. They're coming out, shining, that sort of thing.
Tristan: Yeah, well, it may have escaped yours, but you're not in the sky anymore. Coming out is off the agenda. Shining has been suspended until further notice. Oh, and sleeping during the day is O-U-T. Unless you have some magical ability to sleep while you're walking.
Yvaine: Have you not got it into your thick head yet? I'm not walking anywhere!
