"Don't you worry yourself about that," said Enola, rounding the bed and fluffing the pillows for Hermione to lay back on. "Harry's as tough as treated dragonhide. And Neville and the other members of his Inner Circle will fix him up good as new. He wouldn't be thrilled to think you were bothering yourself about it. He thinks you're worth taking a injury or two, so just put it from your mind. If the lights flicker a bit, don't panic. These rituals require a lot of power. Harry will pull it from all over the palace if he needs it."
