Boy...he doesn't think Derek is a bad person or dislike him...but he wouldn't call him a friend either. He feels a little that the guy is only interested in him for his magic and nothing else, which is disheartening. He also feels a LITTLE concerned that this guy is too reliant on his own magic. He hadn't realized that they were related through marriage, but he's from a big family so he's kinda like "huh about that". Basically, hed help Derek and talk to him sometimes, but I don't think he'd consider Derek a friend.
