"I don't know" he replied quietly "But do I know you? Because you look familiar to me" Harry was telling the truth. He had no memory. Of anything, really, not where he came from or how old he was or even his name. He vaguely thought he remembered the guy shouting, but like an old friend. Harry blinked and shook his head. He needed answers, even if he didn't know what questions to ask. At the moment, he only needed to know one thing.
"Where am I?" yelled Harry back to the guy.
The guy stood up and walked around the entire crater towards Harry.
"Where did you come from?" asked the guy. Obviously this guy was going to be the one asking the questions.
"I don't know" answered Harry
"What's your name?"
"I don't know"
"Why do you look like me?"
"What? Um… I don't know" Harry didn't understand that question. He tried to think really hard. "AAAAARGH!" Harry got a splitting headache.
"I better get you to Chiron" the guy pulled Harry by the arm and half-carried him off the lot. Harry wasn't sure of his surroundings, who Chiron is, this guy or anything. But the one thing he was sure of was that this was going to be a long day.
