After gradually adapting to the chaos at Hogwarts, everyone was surprised to discover that school life had undergone earth-shaking changes.
The professors turned a complete blind eye to all the troublesome things happening in the castle. Even when students openly played Wizard Cards in class, they made no comment. Awarding and deducting points became even more arbitrary.
Ever since the Inquisitorial Squad appeared at Hogwarts, no one had truly cared about points anymore.
During one Charms Class, Professor Flitwick had even gone over to watch Fred and Lee Jordan play Wizard Cards. He chatted with Albert about Charm Innovation magazine, leaving many students dumbfounded.
No one had expected even Professor Flitwick to start slacking off.
Although classes had become very casual, Professor Flitwick's lessons remained popular. Sometimes, on a whim, he would discuss all sorts of interesting topics with everyone, such as his experiences travelling through various countries in his youth. Once, he had even invited Albert to speak to the class about the International Wizard Duelling Competition, broadening everyone's general knowledge along the way.
In fact, after Headmaster Dumbledore had been forced to leave the school, none of Hogwarts' professors took the new headmistress seriously. They were all quite happy to watch her make a fool of herself.
Whenever even a minor issue arose, the professors would have someone go and "invite" Umbridge to handle it, as though no one could settle anything without the new headmistress.
As a result, Umbridge's life as headmistress suddenly became very busy.
Every day, the roaring of Fanged Frisbees could be heard from one classroom or another. Then Umbridge and Filch would have to rush over with large insect nets to help the professors resolve the problem.
Since spells could not be used against Fanged Frisbees, they could only think of another solution.
