Open NPCy thing might be the perfect place to do this. I'm just coming up with excuses for why Kyonko would talk to him and I figure since, hey, she's the gofer as the newest person at the Mudcap she'd be the one being sent off one errands and such.

Kyonko's having a hard time forgetting considering Disappearance. It might be touchy but if he asks her why she got him a present the specific reason is to thank him for staying with her in the hospital.
