It was dark except for their bobbing lumos charms, and all Hermione could make out was figures in the gloom, and the impressions of furniture scattered about. And then the first crack of a spell seared the air. It came from beside her, the flash of orange splitting the air and lighting the room for a second, and Hermione knew it was Draco and turned her head and saw it was Pansy instead, teeth bared and eyes so wide the whites showed all the way around. Hermione shook herself from her shock and turned her face to the battle beginning around her, sparking a cutting hex from her own wand at someone popping up from behind a couch.
