She hadn't even taken a step when a spell exploded the floor between her and Draco and she was flung back, choking and flailing, slamming into the ground hard with her shoulder. She crawled to her feet spitting blood and grit and trying to hold her cries behind her teeth, taking a wobbling step and putting weight on her broken ankle and stifling a scream at the pain. She couldn't see anything but the flashing lights of spells through a haze of dust, and shapes within the dust. She couldn't see Draco, couldn't see Ron, Harry, Neville...anyone. She was all alone and she couldn't walk.
