Yes, and I suppose working with something she doesn't like (werewolves) is a way to make it clear that she'll lower herself for him. It's just the Crouch made it sound as if Voldemort kept her waiting before he gave his approval, so maybe he's cross with her for something. Or he could just be putting her through one of those loyalty games he like so much.

I wonder when I'll have to face one of those.
