"Diffindo!" he cried and Hermione reacted on instinct, shoving Draco to the side, bringing her wand up and sending a silent repulso at the wizard, sending him flying across the room to smash into another enemy wizard. She bit her tongue as the wizard's diffindo sliced into her arm, straight through her Auror leathers. She scrambled to her feet shaking and frantic, checking her arm – it wasn't deep, although the blood was running freely. If she hadn't been wearing her leathers the wizard's curse would have cut straight through the bone though, and she shuddered at the thought. She flicked her wand at another witch who was duelling Fred and George, and took the woman down with a stupefy, and then everything fell silent.
