It's weird for him! He doesn't feel like he's been in Aather all that long (except when he feels like he's been there forever), so it really feels like a fast turnover to him. And he also has issues about being the only one who remembers anything. So he ends up feeling much lonelier about it than there's really any call for. But it isn't something he spends a lot of time thinking about. There's so much other stuff to worry about! But definitely when Hakkai comes back you'll get to see how it affects him, if only because you'll get to see him break down out of relief and happiness.

How are Shion and Roxas doing with the move and so on?
