The silence swallowed them all again. Every head turned, every eye in the place seemed to have found Harry, to hold him frozen in the glare of thousands of invisible beams. Then a figure rose from the Slytherin table and he recognized Pansy Parkinson as she raised a shaking arm and screamed, “But he’s there! Potter’s there! Someone grab him!”
Before Harry could speak, there was a massive movement. The Gryffindors in front of him had risen and stood facing, not Harry, but the Slytherins. Then the Hufflepuffs stood, and almost at the same moment, the Ravenclaws, all of them with their backs to Harry, all of them looking toward Pansy instead, and Harry, awestruck and overwhelmed, saw wands emerging everywhere, pulled from beneath cloaks and from under sleeves.
