The third generation of Dark Lord came from Hogwarts

Lupin's face was obviously nervous.

Then he remembered that he was no longer a student, but a professor, and his expression was obviously relaxed.

Patted Argus's shoulder.

"It's okay, I'm here, Filch won't catch you."

"When the time comes, just say I asked you to help me organize my homework."

When Argus was hesitating about how to explain to Lupin, Mrs. Norris and Filch were already walking quickly.

Mrs. Norris was in front, and Filch was holding a lamp.

The swaying lights, coupled with Filch's heavy footsteps and gloomy face, looked particularly terrifying in the corridor.

Lupin stood in front of Argus and took the initiative to speak to Filch.

"Mr. Filch, are you still patrolling so late?"

"Is it you?" Filch was deeply impressed by this former mischievous student of Hogwarts.

However, it was not a good impression.

"Why are you not sleeping here at night?"

If it were a normal professor, Filch might have just said hello and left.

Unfortunately, it was Lupin!

Lupin's temper is not bad. If it were him in school, he might have turned around and left.

After ten years of social beatings, his mentality has obviously improved a lot.

"Send a student off."

"I asked a Slytherin student to help me sort out my homework tonight. I saw that it was too late and I was worried about being misunderstood, so I came to send him back."

"Sort out homework?"

"Do you think I will believe you?"

Filch sneered twice, and his already gloomy face looked even more frightening.

In his opinion, Lupin used to be a famous "bad student" in Hogwarts, and he must be protecting him now!

Maybe he ran into a little wizard who was wandering at night and wanted to take him away with an excuse!

Humph! Such a person can actually become a professor at Hogwarts!

It's far worse than Mr. Grindelwald who taught in the past!

Lupin rubbed his eyebrows with a headache.

He finally became a professor at Hogwarts, why is he still the same as when he was in school.

He will be checked even if he takes a student to eat supper!

"Mr. Filch, I'm really taking students to eat... sorting homework."

"Hmph!" Filch snorted coldly, and was about to see who it was.

Even if he couldn't catch him, he had to look at the target.

When he caught him next time, we'll settle the old and new accounts together!

"Meow!"

Mrs. Norris hummed comfortably.

Filch thought something had happened to it, and hurriedly reached out to pull Lupin away.

"Mrs. Norris, my Norris... Mr. Grindelwald?"

Argus, who was behind him, walked out holding Mrs. Norris.

Greeted Filch with a smile.

"Mr. Filch, good evening!"

"Mr. Grindelwald, good evening! I just... I just was..."

Filch hurriedly greeted Argus.

Fearing that his words and actions just now would leave a bad impression on Argus.

Argus put Mrs. Norris on the ground.

Mrs. Norris meowed a few times in dissatisfaction, and climbed onto the railing.

"It's my fault, Mr. Filch."

"I need a plant material for an experiment. This plant only appears in the Forbidden Forest at night."

"So I asked Professor Lupin to accompany me."

"I also hope Mr. Filch can keep it a secret for me."

"Of course!"

Filch looked like he had received some important task, and his expression became serious.

But there was more surprise in his eyes because he was trusted.

"Mr. Grindelwald, please go back quickly."

"I just saw Dean Snape upstairs. If he sees you, he might deduct points from you."

"Go this way, you won't run into him here!"

Filch said, and pointed the direction for Argus with his hand.

For fear that he would bump into Snape strolling.

Argus smiled and thanked him, and hurriedly walked along the road Filch said.

He knew very well that a squib like Filch, even if he entered Hogwarts as a patrolman, would be the lowest level of Hogwarts.

Even the young wizards who had just entered school looked down on him.

For Filch, the most important thing was never gold galleons.

But trust! Respect!

Let Filch keep a secret together, so that he can fully experience the feeling of being trusted.

Keeping secrets from each other can also make Filch feel valued, and he is no different from other members of Hogwarts.

And all it takes is a small lie.

Lupin next to him was stunned by Filch's dog-licking behavior.

He couldn't imagine that Filch, who was avoided by generations of young wizards, would respect Argus so much!

In order to prevent Argus from being caught, he even pointed out the way for him closely!

Is this still Filch?

Thinking of the days when they were chased by Filch, he couldn't help but sigh in his heart.

After sending Argus back to the Slytherin lounge, he returned to his office.

...

Lying on the bed in the dormitory, Argus remembered what Filch had just said.

Saw Snape upstairs!

Why did he come out to wander around at this late night?

Could it be that what he just said had such a big impact on him?

He couldn't wait even for a night, and couldn't wait to investigate?

With all sorts of random thoughts in his mind, Argus fell into a deep sleep.

The next morning, Argus went to class as usual.

Two days later, Lupin asked for leave again and disappeared.

It was still on a full moon night.

What is puzzling is that Snape, who has never been absent, also chose to take a leave!

At the same time, two classes were missing, one of which was the most annoying potion study.

This made the young wizards of Hogwarts fall into an unprecedented carnival.

Under the teaching of Argus, the number of young wizards learning the Patronus Charm on campus is increasing.

Even the auditorium approved by Dumbledore to Argus began to become crowded.

They can only barely provide them with magic practice.

In order to maintain good order and to test Hermione's recent learning results.

Argus deliberately let Hermione be responsible for the management and notification of the entire school.

It turns out that Hermione's talent in this area is indeed extraordinary.

Soon the courses were arranged in an orderly manner.

"Argus, I have an important thing to ask you!"

After the weekend class, Hermione waited for everyone to leave, and suddenly nervously grabbed Argus.

"What's wrong? What's the matter?"

"Do you feel something... strange about Professor Lupin?"

"Strange?" Argus looked at Hermione's hesitant expression and guessed her thoughts.

With Hermione's intelligence and having been in contact with him for so long, she has learned a lot of knowledge and events that she had never been exposed to before.

It is not incredible that she can detect Lupin's identity.

"Yes, Professor Lupin's disappearance every month, isn't it... too coincidental?"

"It's always a full moon, and every time he comes back from leave, he looks very weak."

"This is what we have learned..."

"It's very similar to a werewolf, isn't it?" Agus finished the rest of her words for her.

"Hermione, have you ever thought about it."

"What have you thought about?"

"Maybe Professor Lupin is a werewolf?"
