"When we finally found out where they had taken Hermione, we launched a large-scale rescue operation. In fact, I doubt Tom was ever informed they had her, otherwise he would surely have killed her. Both Greyback and Scabior had cast an eye on her long before the battle, so it's safe to assume they've made it their little, shared secret. After we freed her, however, she wasn't the same. She can't stand the touch of hands anymore and there's this constant anger inside her. In the first few weeks after her rescue, she needed intensive medical care because she was injured and severely underweight. She endured each and every treatment without objection, but never spoke about what had happened to her. So I don't know the details either. All I can tell you is that she never fully recovered. I suppose Scabior deserved what she did to him today."
