You know, actually, with Gojyo missing for a few days it's a good excuse for Hakkai to drop by and hot spring it up. He's going to need to unblight himself a bit, and possibly also attempt to relax. (Maybe vent a bit, too, if appropriately prodded....)

He should definitely talk to Yuri, too! I'm not sure yet how the chess game's going to turn out but he can teach her a bit regardless.
