James Wake did not usually enter the unused corridors of the fourth floor. But the moment he heard an explosion, he knew something was up. He was merely walking past, when, at about ten o'clock, he heard the explosion. Naturally, James could stand for such abrupt explosions during the day, but not in Hogwarts. Oh no, he needed to keep a real presence at Hogwarts. It was his job as Imperium Squad member, after all. Keep the peace. James was not usually gung-ho about the prospect of finding troublemakers, but today, he was in a foul mood. Cracking his real knuckles, James whipped out his wand, and began to search each room for the offensive pyrotechnic.
It did not take long to find Keith Nicholas. Internally, James groaned as he found his on-again-off-again little foe messing with a cauldron. On the outside, however, James remained stoic. He had only crashed down the door. In addition to Keith, there was an older student. That was most troublesome for James. If Keith had found co-conspirators, then James' job would be a lot harder. And James was in no mood for extra trouble. James held his wand, pointing it at Keith as he entered the empty classroom, careful to avoid any strang(er) ingredients. "Keith, what are you doing THIS time?" he asked.
