Re: WHO.
JC came early to get some tips from George and practice flying on a broom instead of a sword. He's highly competitive but not practiced in team sports. He'll do his best to not embarrass himself.
Shiro came just to watch. (I'd love to have him play but with two teams, there's only a few slots? If there's another round, I'd loved to throw him in! He's an excellent flyer and more athletic than JC by a mile tbf.)
