Draco stepped up beside her, Pansy clinging to his side as they all formed a ragged, bunched line along the invisible boundary of the Caterwauling Charm. He smiled at Hermione, trying to be reassuring she assumed, but his lips were tight and his grey eyes cold and hard, and she wasn't reassured. She smiled back though, weak and quavering, and shifted her grip on her wand, trying to will her heartbeat to slow, trying to control the rush of adrenaline making her tremble and her muscles sing with unreleased energy. And then Lupin ran forward and a wailing split Hermione's head in two, driving into her ears, surrounding her in a crush of oppressive sound.
