Chapter 137 "It's Me"

Two days later, Sherlock felt his emotions returned to normal and finally returned to class. As soon as he came to the classroom before he could speak, a large group of sixth graders complained.

"Professor, he forced us to learn werewolves!"

"Didn't you tell him that I told you everything about werewolves that I could tell you?"

"We talked about it, but he insisted and said we don't understand werewolves at all, and he'll tell us how to identify a werewolf and kill it."

"He won't let us answer the questions. Even if he asks a question, he won't let us say it. He would only talk about the knowledge we have memorized over and over again."

"We told him that this class is a practical class. We have learned the theoretical stuff, but Professor Snape didn't listen to us!"

"He also gave us two rolls of parchment werewolf essay! We have to do exam papers on time, and we don't have time to write this!"

Snape taught all the classes these two days, and the students complained. He completely ignored the normal teaching process. Even in the first-grade class, he insisted on explaining werewolves to the children who had just learned the Levitation Charm.

If there had been nothing wrong with him, Sherlock would have plucked his head off his head. Combined with the weird energy he had when he and Lupin went to Snape to help with the class, he must be hinting at something by taking these classes.

But Sherlock had to finish the mess he had made. If he had known earlier, it would have been better to let the students study by themselves at the beginning so that they could use the time they had to do the exam papers.

He shook his head, "Okay, I originally wanted to teach you the exam papers in this class. Looking at it, let's make up for the combat class that I didn't take last time."

There was a burst of cheers in the classroom, but there were still students who did not forget, "But what about the two parchment-long essays he made us do?"

Sherlock waved his hand, "You don't have to do the homework Snape gave you. I'll tell him about it later."

The students' cheers couldn't help but grow even louder. The sixth grade's combat class was not as good as the seventh grade's. Sherlock's main purpose in this class was to teach them the application of some spells rather than one-on-one duels.

For example, the advanced usage of universal unlocking charm, the advanced usage of Protego Charm, and so on.

On the same day that Sherlock returned to class, Harry also came out of the school infirmary. Madam Pomfrey forced him to lie in the ward for so many days, but after he woke up on the first day, there was nothing wrong with his body.

But what saddened Harry was that when he fell, his broom was blown by the wind and torn to shreds. It hurts him more than losing a Quidditch match.

The Nimbus 2000 was not only the broomstick that accompanied him for years but also a gift from Professor McGonagall after he joined the Gryffindor Quidditch team. 

Back in class, and this time Professor Lupin is finally back, this is the only thing that can make Harry feel a little better. In this class, Lupin dismissed the homework assigned to them by Snape and continued their previous teaching plan, talking about the dark magic creatures living underwater.

When Snape didn't teach the class, it made all the students in the castle very comfortable, and his intentions seemed to be in vain. Except for Sherlock, no other students doubted why he had to teach werewolf in class.

After the Defence Against the Dark Arts class, Lupin met Harry alone. Lupin didn't watch the game, so he didn't know what happened to him. He tells Harry about Dementors' abilities, reassuring him that it's normal to be afraid of Dementors, it's just that Harry has experienced more fear than anyone else.

Harry was saying something weird about it because just before he fainted on the field, the voice of his mother when Voldemort killed him came up in his head.

"You used a spell on the train to make that Dementor retreat." Harry said suddenly.

"There were certain spells that people could use," Lupin said, "But there was only one Dementor on the train. The more of them, the harder it was to defend."

"What kind of spell did you use?" Harry asked immediately. "Can you teach me?"

Lupin looked at him, shook his head, and smiled, "To be honest, Harry. I'm not really an expert on Defense Against the Dark Arts, nor am I good at dealing with Dementors."

"But I will be completely defenseless if I meet them again." Harry said firmly.

Lupin looked at him, hesitated for a moment, and then suggested, "If you really want to learn it, I suggest you go to Sherlock. He is an expert in this field. Before I came to teach at Hogwarts, I also read the book he wrote about dark magic creatures. His knowledge of Dementors is among the best in the wizarding world."

Harry was stunned for a moment, "Professor Forrest?"

"Yes, Sherlock. He is talented. He is at the forefront of the wizarding world in the study of Defense Against the Dark Arts. Plus, I have something to do before Christmas, and it would be a bad time to teach you during that time."

It's not that Harry doesn't want to go to Sherlock because of the experience of traveling together during the vacation; it can be said that Sherlock is Harry's closest teacher in the castle. 

But it is clear that he was afraid that he would never learn it or that bad things might happen to him again because of his jinx. But Harry really wanted to learn the magic that could deal with Dementors this time. After hearing Lupin's recommendation, Harry finally decided to follow his words and go to Sherlock.

Sherlock was marking fifth-grade homework when Harry came into the office. He heard Harry's request and looked up at him suspiciously.

"Now, why would you be asking my help to learn a spell?"

"Professor Lupin told me that you are an expert in Defence Against the Dark Arts. I asked him to teach me, but he said he is not good at dealing with Dementors, and he has other things to do."

Sherlock didn't pay attention to the other things. Instead, he noticed Harry's last sentence. 

"Lupin said he had other things to do?" He asked, rubbing his chin.

Harry didn't know why Sherlock asked this; he nodded, "Yes, Professor Lupin said he was ill and needed to go somewhere else."

Sherlock thought for a while, then stared at Harry and asked, "Did he look pale and frail?"

Harry followed his words, recalling how he saw Lupin, "He seems to be very weak, and his face has always been pale."

Sherlock muttered to himself, "Very similar, but it can't be true..."

"What is it?" Harry asked blankly.

"It's nothing." Sherlock changed the topic, "Since you want to come and learn, I will not refuse. But the Patronus Charm is not a simple defensive spell. It is difficult to learn. You have to be prepared to learn it for a long time."

Harry's eyes were firm, "I will take it seriously, Professor."

"Follow me and study hard. From today, come to my office every Saturday and weekend night, and I will teach you how to use this spell."

Sherlock and Harry made an appointment and sat and thought for a long time in the office. Near lunchtime, Sherlock left the office and found Lupin, who seemed much more sluggish than before.

"Would you like to go to the Hall for something to eat?" Sherlock asked, leaning against the door frame.

Lupin smiled and refused, "You should go by yourself. I have other things to do."

"I have something I just want to ask you."

Hearing Sherlock's words, Lupin was startled, and he seemed to know something. His smile became slightly bitter, and he stood up from the chair with a sigh.

"Okay, let's talk while we eat."

They walked to the Hall, and neither of them spoke on the way. There were not many people in the Hall. It was not yet lunchtime. It would take half an hour for all students to come.

There was no one at the professor's table. Not all professors are used to coming to the Hall for lunch. They would have house elves deliver their food to their office.

Sherlock and Lupin sat together with no one around them.

"Snape taught a lot about werewolves when he was a sub. The students complained and kept saying that he seemed to have a werewolf as an enemy."

While Sherlock was talking, Lupin drank the pumpkin porridge calmly.

"You told me before that you did something wrong to Snape. His enemy is you, isn't it?"

The scene was suddenly silent, and after a long time, Lupin spoke softly, "I didn't expect you to ask so directly."

Sherlock shrugged, "I don't like to beat around the bush. Generally, if there is any question, I will ask it directly if I think it is the correct time. If it is not the correct time, I will ask it when it is."

"Since there are doubts about some things, it is the best way to ask them directly." Lupin took a deep breath and nodded in recognition.

"Snape was right. There is a werewolf at Hogwarts right now, and it's me."
