Foster doesn't really seem fazed by Reira's thousand-yard, empty stare. Possibly because he doesn't spend much time looking at people. Not the way most people look at other people, with an eye for what fits and what does not.

Nothing fits, or doesn't fit, the way Foster sees things. It's a much more complex equation than that, one with constantly shifting parametres and levels of attention paid--one that, unfortunately, he struggles to articulate even within himself, and so will probably never manage to make sense to anyone else.

Either way, he seems to accept Reira's response as fairly inoffensive.

"It's fine! It's fine as long as it's still bleeding," he assures her, as though that makes any sense at all.
