So Gladdy might talk to him, might not. I actually have no idea how she'd react to finding out about him, because...she surprises me all the time.
Pearl will hate him for being a dirty half-breed.
Donnie won't care.
Severus will be disdainfully distant, but not really judge...only he will totally judge because that's what he does.
Jane will probably hate him for being a man and a half-breed.
Rose doesn't judge anyone or anything, and she might talk to him.
AND FINALLY BELLA. She thinks he's a dirty half-breed and will probably condescending like she is to everyone. I will figure out shortly who is the DE in charge of Fenrir's pack, so you have someone to interact with on a regular basis. And by that, I of course mean the groups the DEs are divided into to keep security among the upper ranks, and since Voldie doesn't fully trust Fenny yet, there is a DE who meets with him separately and then with the pack. I'll let you know when I get that.
