Unfortunately, it was the girl's attractive features that were her downfall. Snatchers were vile creatures. As much as she might have had a fondness for Fenrir Greyback, the cretins he presided over were the very dregs of society. Despite ordering them to leave the girl unharmed, at least one of them was incapable of keeping it within his trousers. She'd arrived bruised, battered, incoherent, and completely useless. Even if she was nursed back to health before Hermione tortured her again, it would be for nothing. She put the girl out of her misery with a simple Avada and tortured the Snatchers instead for their incompetence. After all, she already had everything prepared. No sense in wasting the opportunity.
