I’ve been to restaurants that required bathroom visits like this before. I’m sure most people have, which is why Tetsu Kochou (you’ll learn what the name means next week if you haven’t already plugged it into an online translator) doesn’t immediately realize Silence teleported away.
The “aw, dang” is a reference to the superhero movie Mystery Men. In it, Captain Amazing (played dashingly by Greg Kinnear) inhales a blast of chloroform while examining a gizmo belonging to Casanova Frankenstein (Geoffrey Rush). He looks up in confusion, then realizes he’s been doped, and yells out “aw, dang!” right before passing out. It struck me as one of the funnier scenes in the movie which was already pretty good to begin with.
