Re: question
Big fluffy baby. Well, he likes pretty things and, as I noted in his stuff, he does enjoy making friends despite his actually-worse-than-doumeki quietness. So I think he could easily pick up on things like gardening or helping with food, basically the sort of things people like Sakura or Freya or Snow could show him or enjoy. The logic there being that plants and flowers are pretty, of course, and food helps bring people together (nevermind he likes it a lot).
He's also a good swordsman so he could actually practice with the others who are, like Arthur or Porthos.
Do you see Elsa breaking free of her fears towards her own magic without the intervention of Anna in some way?
