Harry did stop to consider that, for a second. It was true that Voldemort had pulled something like this before, except-- "I don't know where," he said. "If he'd been trying to lure me into a trap, he would have showed me where, right? And--" he really didn't want to dash all of Hermione's hopes, but the more he thought about it, the more he knew she was wrong. "I don't think he'd know what they looked like."
He raised his hands to his eyes, rubbing at them. "He must want me to- I don't know- come out of hiding and challenge him directly." Which was precisely what Harry wanted to do. He hated that if he did it, it would probably be playing right into Voldemort's hands - but what else could he do?
