It happened to be 8am on a Wednesday (thankfully) and Tori was heading upstairs to owl her daddy. She turned into the Charms corridor and started down it, munching on a piece of toast.

Suddenly, she got a distinct feeling that she was walking upstairs, even though she knew full well that she had just gotten off the stairs. Oooohohohohh what was this? Whatever it was, Tori didn't like it. She scrambled for the wall and sort of clung to it, eying the entire corridor and all the objects floating on the ceiling with suspicion.

"You there," she called out, throwing her toast's crusts at the girl ahead of her, "What did you DO to the FLOOR?"

Because obviously, she could tell from the girl's uniform that she was a Puffer, and all Puffers were Duffers who were responsible for everything bad that went wrong in the world.
