“Protego!” roared Harry, and the Shield Charm expanded in the middle of the Hall, and Voldemort stared around for the source as Harry pulled off the Invisibility Cloak at last.
The yell of shock, the cheers, the screams on every side of “Harry!” “HE’S ALIVE!” were stifled at once. The crowd was afraid, and silence fell abruptly and completely as Voldemort and Harry looked at each other, and began, at the same moment, to circle each other.
“I don’t want anyone else to try to help,” Harry said loudly, and in the total silence his voice carried like a trumpet call. “It’s got to be like this. It’s got to be me.”
“Potter doesn’t mean that,” he said, his red eyes wide. “That isn’t how he works, is it? Who are you going to use as a shield today, Potter?”
“Nobody,” said Harry simply. “There are no more Horcruxes. It’s just you and me. Neither can live while the other survives, and one of us is about to leave for good. . . .”
