One of their first ideas involved setting off a whole box of wizard fireworks at once. Their product was far better than Dr. Filibuster's offerings, I must say. It was Guy Fawkes Day in the spring, and, much to my private amusement, none of the teachers would lift a finger to do anything about the fireworks. Only Filch the caretaker was on her side, and he's a Squib. I wonder what she offered him? Even though most of the faculty could have taken care of the fireworks with no problem, they blandly said that they didn't think they had the authority to do so, since the High Inquisitor had forbidden them to speak of subjects other than those they were paid to teach.
