For as long as he'd been working at Hogwarts, Filch had sent Mrs. Norris off to find troublemakers and rule breakers. And for as long as the two had been doing such, Mrs. Norris had found all manner of problem children. Today was no different. Even as he'd been working in the locker room trying to fix a stubborn broken locker door, Mrs. Norris was on the case.

At her meow, he looked down. "Troublemakers, eh? Good work, my love." Then, following the cat, he was led further into the locker room and then into the loo area. His beady eyes looked about and, when they landed on Grant McKinney, he looked a bit puzzled.

"What's all this, then?" he questioned, looking to see what else was amiss. There appeared to be nothing, but he would never concede that Mrs. Norris had been wrong. And, as his eyes came back to the shirtless Mr. McKinney, he realized she hadn't been wrong. His brows rose as he saw the bra being held by the boy. "Where's the girl, then?" he asked, Mrs. Norris already moving slowly about the loo.
