He laid the broken wand upon the headmaster

He laid the broken wand upon the headmaster’s desk, touched it with the very tip of the Elder Wand, and said, “Reparo.”

As his wand resealed, red sparks flew out of its end. Harry knew that he had succeeded. He picked up the holly and phoenix wand and felt a sudden warmth in his fingers, as though wand and hand were rejoicing at their reunion.

“I’m putting the Elder Wand,” he told Dumbledore, who was watching him with enormous affection and admiration, “back where it came from. It can stay there. If I die a natural death like Ignotus, its power will be broken, won’t it? The previous master will never have been defeated. That’ll be the end of it.”

Dumbledore nodded. They smiled at each other.

“Are you sure?” said Ron. There was the faintest trace of longing in his voice as he looked at the Elder Wand.

“I think Harry’s right,” said Hermione quietly.

“That wand’s more trouble than it’s worth.” said Harry. “And quite honestly,” he turned away from the painted portraits, thinking now only of the four-poster bed lying waiting for him in Gryffindor Tower, and wondering whether Kreacher might bring him a sandwich there, “I’ve had enough trouble for a lifetime.”
