“But you’re dead,” said Harry.

“Oh yes,” said Dumbledore matter-of-factly.

“Then . . . I’m dead too?”

“Ah,” said Dumbledore, smiling still more broadly. “That is the question, isn’t it? On the whole, dear boy, I think not.”

They looked at each other, the old man still beaming.

“Not?” repeated Harry.

“Not,” said Dumbledore.

“But . . .” Harry raised his hand instinctively toward the lightning scar. It did not seem to be there. “But I should have died — I didn’t defend myself! I meant to let him kill me!”

“And that,” said Dumbledore, “will, I think, have made all the difference.”
