Art Booths
Remus keeps a measured difference from Belby and the potions competition. Yes, he'll happily support Lily, but he has all sorts of mixed feeling about the work that Belby is doing. As much as he might want to learn more, he is so very over the false hope and quest for the cure.
He does, however, wander off from his friends and spend a good amount of time talking with a few of the artists displaying their works.
