You do not seek to kill me, Dumbledore?” called Voldemort, his scarlet eyes narrowed over the top of the shield. “Above such brutality, are you?”

“We both know that there are other ways of destroying a man, Tom,” Dumbledore said calmly, continuing to walk towards Voldemort as though he had not a fear in the world, as though nothing had happened to interrupt his stroll up the hall. “Merely taking your life would not satisfy me, I admit.”

“There is nothing worse than death, Dumbledore!” snarled Voldemort.

“You are quite wrong,” said Dumbledore, still closing in upon Voldemort and speaking as lightly as though they were discussing the matter over drinks. Harry felt scared to see him walking along, undefended, shieldless; he wanted to cry out a warning, but his headless guard kept shunting him backwards towards the wall, blocking his every attempt to get out from behind it. “Indeed, your failure to understand that there are things much worse than death has always been your greatest weakness”

Another jet of green light flew from behind the silver shield. This time it was the one armed centaur, galloping in front of Dumbledore, that took the blast and shattered into a hundred pieces, but before the fragments had even hit the floor, Dumbledore had drawn back his wand and waved it as though brandishing a whip. A long thin flame flew from the tip; it wrapped itself around Voldemort, shield and all. For a moment, it seemed Dumbledore had won, but then the fiery rope became a serpent, which relinquished its hold on Voldemort at once and turned, hissing furiously, to face Dumbledore.
