J. K. Rowling: I said to Arthur, my American editor - we had an interesting conversation during the editing of seven - the moment when Harry takes Draco's wand, Arthur said, God, that's the moment when the ownership of the Elder wand is actually transferred? And I said, that's right. He said, shouldn't that be a bit more dramatic? And I said, no, not at all, the reverse. I said to Arthur, I think it really puts the elaborate, grandiose plans of Dumbledore and Voldemort in their place. That actually the history of the wizarding world hinged on two teenage boys wrestling with each other. They weren't even using magic. It became an ugly little corner tussle for the possession of wands. And I really liked that - that very human moment, as opposed to these two wizards who were twitching strings and manipulating and implanting information and husbanding information and guarding information, you know? Ultimately it just came down to that, a little scuffle and fistfight in the corner and pulling a wand away.
