I'd looove for K to get to do more with music. Playing for Jayce and even playing with him if Jayce knows/learns any instruments too. To a lesser extent K's also been practising singing (because how could I resist? dude has a nice singing voice), he's just kinda shy about it, but serenades are a possibility. Lol including cat "serenades". I'm definitely interested in Jayce teaching him how to draw and build things! Teaching him anything, really. Like... maybe even... how to be a person? c: I mean, that's going to be happening anyway as they spend time together.

Ooh yes sparring! I spaced on that so I'm glad you brought it up. When we had a Dr. Strange in game here, he and K had an arrangement: K physically sparred with him to help keep him sharp, and in exchange he taught K about the mystic arts and such. So he could help out Jayce there. I've been playing it as, he can play/spar/wrestle with humans, he just won't be able to intentionally injure them in his humanoid form (yet — once he's developed genuine free will, all bets are off).
