There are too many bodies in the room, and Hermione wants to scream as Malfoy settles on his knees. She clutches at her throat, her breath coming short. It makes her think of a revel. A witch steps between her and Malfoy blocking Hermione's line of sight and looks her in the eye. "Merlin, it is you," the witch says in a familiar voice, and Hermione realises with a shock that snaps down her spine, that it's Cho Chang, staring at her as if Hermione is a ghost.
