I'm thinking Axel might get Roxas the Snowstar Scarf from the reward shop. Mostly as a thank you for sitting out with him on a chilly boat during Ghoul's Moon night and possibly to mollify any worrying he might have caused by jumping into the Farplane so haphazardly

Just. It's a scarf that's seasalt ice blue and magically keeps the wearer warm, it seems too thematically fitting not to!
