Moments before they had been losing a duel with a masked Death Eater when a stunning spell from behind dropped the man, but the girls fled without a second thought. They were trying to find Harry, sprinting towards the astronomy tower when Hermione felt her wand fly out of her grip. Panic settled in her stomach as Fenrir Greyback stalked in their direction, only meters away, but Bill put himself in front of his path, shielding his sister. There was something innately terrifying about Greyback. He was the only werewolf Hermione had heard of who was capable of permanently staying half-transformed, and he was a deadly presence, with or without a wand. Remus had arrived, shouting for her and Ginny to run, and Hermione didn’t waste any time, grabbing her friend's hand to find a place to hide. They fled down the corridor, but not before Bill screamed in pain.
