All things are three at Hogwarts

"It's too much. Everyone is talking, and he has to punish Ravenclaw!" Edward complained.

After Percy turned around and left, Allen secretly stretched out his wand, and a circle of light attached to Percy's back, "hb"!

"Everyone knows that headboy is the president of the male student council."

The Ravenclaw further away said in confusion.

Michael on the side sneered, "humungous bighead, a huge head. It's really yours, Allen!"

Apparently, it wasn't just Michael who understood this. Where Percy walked past, uncontrollable laughter could be heard from the sleeping bags around him.

"Quiet, quiet!" Percy scolded with an air of air.

The candles have all been extinguished.

Only those silver ghosts gave off a little light, floating around and talking seriously to the prefects.

The enchanted ceiling looked like the sky outside, dotted with stars.

Under such a ceiling, listening to the whispers still ringing in the auditorium, Allen felt as if he was sleeping in the breeze outdoors.

After a while, Professor Flitwick came to the Great Hall to check if everyone was okay.

Professor Flitwick visibly breathed a sigh of relief when he saw Allen and Penello.

He left without questioning Allen or Penello, and left after dutifully patrolling the auditorium for a week.

Every hour, a teacher appeared in the auditorium to check that everything was okay.

At about three o'clock in the morning, when many students finally fell asleep, Professor Dumbledore walked in.

Allen, who was both hearing and sighted, immediately woke up from his half-dream.

Alan looked at Professor Dumbledore. He found Percy and asked about the situation in the auditorium.

The door to the auditorium creaked open again, and there were more footsteps.

"Headmaster?" It was Professor Snape. "The entire fourth floor has been searched. He is not there. Filch has also looked in the underground classroom, and he is not there either."

"Where's the Astronomy Tower? Where's Professor Trelawney's room? Where's the Owlery?"

"I've searched them all..."

"Very well, Severus. I also expected Black not to linger here."

"Have you ever wondered how he got in, Professor?" Snape asked.

"There are many ideas, Severus, but they are all equally untenable."

Next, Professor Snape's voice was almost inaudible, and even Alan couldn't hear it clearly.

But from the trembling on his face, Allen could guess the anger in his heart at this time.

Alan knew that he must be suspicious of Professor Lupine, thinking that it was Professor Lupine who brought Sirius Black to Hogwarts.

"I don't believe there is anyone in this castle who can help Black break in." Dumbledore increased his voice, his tone clearly indicating that the topic was over, and Snape said nothing more.

"I must go down and find those Dementors," said Dumbledore. "I said I would notify them when we were done."

"Aren't they here to help, sir?" said Percy.

"Oh, yes," Dumbledore said coldly, "but as long as I am Headmaster, I am afraid that not a single Dementor will be able to cross the threshold of this castle."

Percy looked a little embarrassed.

Dumbledore left the Great Hall, walking quickly and quietly.

Snape stood for a moment, staring at the headmaster's back with deep resentment on his face. Then, he left too.

In the next few days, there was only one topic in the school, and that was Sirius Black.

The accounts of how he broke into the castle became increasingly bizarre.

Apparating, flying in, coming in disguise... Hufflepuff's Hannah Abbott had the most bizarre idea that Black would turn into a flowering bush.

But no one guessed that Sirius was an illegal Animagus.

Maybe Lupine can guess it.

But the person who appeared in the Defense Against the Dark Arts class again shocked all the Ravenclaws.

Not Professor Lupin but the terrifying Snape.

"Professor Lupine did not leave any records about what you have learned, so who can tell me what you have learned?" Professor Snape scanned the audience with a dangerous gaze.

All the little wizards' eyes turned to Allen.

Alan raised his hand bravely, knowing that no matter what he said, Professor Snape would definitely criticize Professor Lupin to the bone.

Professor Snape narrowed his eyes, "Very well, Alan, please tell me what is in your empty heads."

"Sir, we have learned Boggart, Red Hat, Cabba and Grindylow. Now we are preparing to challenge magical creatures with higher ratings from the Ministry of Magic."

Since Allen opened his mouth, he would not be easily interrupted. He ignored Professor Snape's dangerous eyes and loudly spoke the content of the course taught by Professor Lupine.

To be fair, Professor Lupine is a really good teacher.

"It seems that Professor Lupin has not put any burden on you. I think first-year students should be able to deal with red hats and Grindylow. We are going to discuss today."

All the Ravenclaws watched curiously as he flipped through the textbook until he reached the last chapter.

"Werewolves," said Professor Snape.

"Now, everyone, turn the books to page 394." He glanced at the shocked classmates again, "Everyone! Hurry!"

Although everyone did not understand why Professor Snape did this, smart Ravenclaws realized that this must be due to the personal grudge between Professor Snape and Professor Lupin.

In front of the menacing Professor Snape, all the Ravenclaws opened their books to the chapter on werewolves and wisely remained silent.

Obviously, such a Ravenclaw made Professor Snape unable to burn his anger. He arranged for everyone to copy notes about werewolves from books, and then patrolled back and forth between the desks.

Such coursework is not difficult for Allen, but Allen's mind is not on these boring excerpts.

What he was thinking about was whether to tell Professor Lupin everything about Sirius Black.

But if the reckless Black really has help,

Allen felt that he must not be so straightforward. Lupine had no control over Sirius Black's actions.

Telling him would not help the matter, but might make the matter worse and make Allen lose the opportunity.

In the end, Allen gave up the idea.

The bell finally rang, but Professor Snape didn't let them leave.

"Each person writes a paper and gives it to me. The content is how to identify and kill werewolves. I ask you to fill two volumes of parchment on this topic and hand it in on Monday morning."

The Ravenclaws nodded reluctantly.

"I heard that Ravenclaw's new bulletin board is amazing, so Alan Harris, it's up to you to post the outstanding papers I selected on the bulletin board." Professor Snape continued.

What else could Allen say, he nodded in agreement.
