Ron & Charlie
Ron turned when someone spoke to him, calling him magic kid. "Uh, yeah, that's me," he said. He glanced at the girl, confused. "Uh... who are you again?"
If he was being rude, he wasn't meaning to. He really did forgot if he'd spoken to this girl before. Sometimes he forgot things, especially if he wasn't in a great mindset at the time. If they spoke when he first arrived, then there was a good chance he couldn't remember at the moment.
