Harry doesn't recall Draco's hands leaving him at any point during the rest of the night, except once. She hovers around him like a clingy ghost; her hand tracing aimless shapes on his hip when they stand at the bar, nosing behind his ear when Luna drags both of them down to dance because Bronski Beat is playing, and Harry behaves. He's unsure if Draco's constant presence is making it easier or harder to obey her rule, but it doesn't matter, because he's floating on air. His mind feels giddy, yet quiet and singular, and again, it's easy. Maybe he would feel a bit more self-conscious with Ginny around, but there's no room for those types of worries. In any case, she is just as attached to Pansy as he is to Draco, so Harry supposes they're all right.
