Hermione is finally getting over the fact that he's being civil to her, so they should totally be friends and hang out. It was freaking her out for a bit, but she's just like, whatever this world is weird, and is over it.
I have a lot of pups that will be joining the magic collective that he can be friends with. Gaius and Twilight are closest to his age and will get along with him just fine. Whenever we finally get everything together we should start a big log so everyone can meet and chat and all that.
