Re: NOTEWORTHY THINGS.
Sirius is a sane person, mostly, so he doesn't participate in Quidditch. Likes watching it well enough, but he left the enthusiasm for playing the sport to James.
He asked Bonnie and Caroline if they wanted to come along to watch (or if they wanted to play, go for it! He'll watch the kids). He was there to support Ras (did you play??? If you did, you were supported!) and everyone else on, as he provided commentary alongside Emme and kept score.
