Death Eaters
Fenrir on the other hand, is angry and hurt and probably had to be sedated XD He had a nice chunk of his chest blown away, ty Dorcas, and loads of burns and some broken ribs and there's a hole in his thigh that probably shattered a bone that needed to be regrown.
Um. if it's okay with modlings, I think he might have bitten one of the Healers trying to fix him when he woke up. :P
