Harry looks from Pansy to Draco, to Blaise, and back at Draco again, and realises then that they all know something he doesn't. Draco just laughs and flips Pansy off as she and Blaise disappear back inside. And then suddenly they're alone on the deck and Harry wonders when he stopped being in control of the situation. Draco hops down from the railing, but even on equal ground she's  so tall  that Harry still has to look up to meet her eyes. It makes him feel—well. Hunted. Which, he now supposes, is the intended effect. Draco cocks her hip against the bannister and does that thing again, that quick smile with her tongue between her teeth. Harry feels himself flush, the heat crawling up from his chest, over his neck and up to his ears.
