There's a couple, probably related by the looks of it, who wouldn't be out of place in his galaxy. The game's not one he's familiar with, but he knows even less about the games of non-human species than he does about the species. He doesn't play a lot of games during his downtime for the resistance. He doesn't even have a lot of downtime.

If they're communicating silently, that sounds like it could be possible, with what he knows of the Force. Not that he's seen many personal demonstrations of it.

He's not sure he should interrupt, so he'll just be watching them while keeping an eye out for someone who looks familiar.
