Evan wanted to come up with something that hadn't been told, but he really couldn't think of anything. Engorgio, reducio and diffindo were charms he'd have told too could he think faster. He then decided to give a really simple and basic thought go. It wouldn't hurt if he was wrong, right?

He raised his hand hesitantly, as if afraid of being seen. "Could it be saying the incantation more fiercefully to have more? Like you shout the spell 'aguamenti' and you have more water than you'd have normally?.." Yeah, time to lower your hand after rumbling. Maybe the professor wouldn't hear.

Perfect, and now he was late. He knew he never should have answered. He shook his head slightly. He didn't know a duplication spell. Sigh. He sooo should have stayed in common room.
