[@Sisyphus] Sure.  They've probably been introduced at some-point, and at the very least know of each-other. Arthur could even know what she's doing in Galinas, maybe have a correspondence with her to get information about the science happening over there. Doesn't seem the type to care about national rivalries.

I don't know - I'm planning for a big part of Arthur's character arc to be 'learning how to have interpersonal relationships', so I think a long-term pen pal situation is a little out of his depth at the moment. :P Maybe they just know each other in a 'social function' kind of way?
