HP in the name of Slytherin

After determining the time of departure, Catherine and the other two became very low-key, trying to minimize their impact on the world.

Catherine was a simple person. Without the threat of Voldemort, she would go to the library to read when she had nothing to do. She would quickly copy down the books that did not exist in her own world but were available in this world, preparing to expand the book reserves of Hogwarts in her own world.

With Dumbledore's permission, she could even come and go freely in the restricted area.

Of course, adhering to the principle of reciprocity, Catherine also left behind some magic books that were not available here but could be used.

It's not difficult for Tom. He can capture the hearts of all the first-year Slytherins within a week. If he wants to keep a low profile, he just needs to be less active.

At first, Draco didn't know why Tom suddenly became "lazy", so he tried hard to take him "out to play" and even wanted to invite him home.

This made Tom feel very sorry, so he could only tell Draco that he would go home with Catherine after Christmas.

In the world of young Draco, there was a place he had never heard of and he would never be able to go there, and Tom didn't want to tell him about the two worlds. If that happened, there would be too much to explain.

He also didn't want to go to the Malfoys' house, didn't want to see the Abraxas of this world who had been turned into a portrait and didn't recognize him at all.

So the two friends had a cold war for the first time. Draco wanted Tom to explain, but Tom didn't want to explain so much.

In the end, of course, the one who was more dedicated surrendered first. As long as Draco thought that Tom was leaving after Christmas and would never come back and there would be no way to contact him, he couldn't continue to be upset with Tom.

His father told him that everyone has secrets and no one will be with him forever. All he can do is cherish what he has.

The 11-year-old Draco seemed to understand, but in the end he only understood that his father told him to stop quarreling with his friends and cherish the last time they spent together.

It was so sad, he thought he could be good friends with Tom for life, study together, grow up together, work together, get married and grow old together. He had never seen a little wizard as smart, polite and funny as Tom, who was so talented and so humble. He was modest and never made people feel humble. He always made people feel comfortable and happy... except for this cold war.

But Draco was not a fool. During the Cold War, he noticed that Catherine and Severus, who were with Tom, had become very low-key and were reducing their contact with other people. He knew that the three "siblings" were really going to leave.

Fortunately, the great Harry Potter shared the same pain as him.

Catherine and Severus had a very good relationship with him before, and they often went out together. Draco didn't know that Catherine and Severus were protecting Harry at the time, he just thought that they were inseparable like him and Tom.

As a result, Catherine now goes to the library alone all day, and rarely even takes Hermione with her. Severus often goes to Professor Snape's office, or goes to the library to accompany Catherine. Harry can only play with Hermione and the not-so-bright Ron.

Alas, it's so pitiful. They share the same suffering and sympathize with each other. After Catherine went to the library with Severus again one time, Draco saw Harry's complicated look of loss and sadness, and suddenly he felt balanced.

At least Tom still accompanies him to do homework and play together. It seems that Tom treats him much better.

The young master then became a little happy again.

In fact, Catherine didn't always go to the library. She just used the name of going to the library to often disappear from everyone's sight, so that she could do more things afterwards.

For example, after Ariana was born, she helped the Dumbledore brothers design a small magic that could allow them to hear Ariana's voice, so that Ariana, who had become a baby, could communicate smoothly with her brothers.

But because she was a girl after all, a tiny baby, Aberforth couldn't do everything by himself, so he hired a nanny to take care of Ariana temporarily until she could move around on her own.

The nanny was recommended by Grindelwald. She was a very elegant and gentle middle-aged woman. It was said that she was originally Grindelwald's subordinate and a very powerful witch in Grindelwald's camp during the First Wizarding War. After the war, she used various means to escape punishment. She has been working secretly for Grindelwald over the years.

Now that Grindelwald has turned over a new leaf and only wants to be a teacher at Hogwarts, the lady still follows him.

After much consideration, Albus agreed to the lady's application. This way, after a year or two when Ariana can take care of herself, this lady can join Hogwarts and fill the professor positions that Hogwarts has been short of for thousands of years. He can also closely monitor the movements of Grindelwald and others.

Even with Catherine's contract, Albus has become accustomed to taking the initiative. He believes more in what he sees and what he can control. Catherine respects Albus's choice.

The relationship between the Dumbledore brothers warmed up because of Ariana's resurrection, but there was still some tension with Grindelwald. Aberforth, for the sake of Ariana's face, had to remain polite to Grindelwald on the surface, while Albus had to frequently contact Grindelwald.

The two of them were once so familiar and close, but now they rarely communicate outside of official business.

Grindelwald would not use Ariana as an opening statement just because she had a friendly feeling towards him. Albus didn't know what else he could talk about with Grindelwald besides work... nor did he really want to talk.

Once he made a mistake, he trapped himself in the high tower of the Hogwarts headmaster's office for decades. The same is true for Grindelwald. The relationship between the two will not be eased so quickly, and it is even unknown whether it can be reconciled. But as time goes by, perhaps they can find a way of getting along that is more comfortable and reassuring for both of them, which is also not bad.

At least when Catherine went to the headmaster's office to find Albus later, she saw Grindelwald reading a book in Albus's office - he would become a senior Defense Against the Dark Arts professor at Hogwarts next year, so it was natural for him to come here early to familiarize himself with the work.

As for why he didn't stay in Snape's office arranged by Dumbledore, or found another place, the latter was unknown, the former was because Snape had been very busy recently.

Grindelwald is a senior professor at Hogwarts. For the lower grades, Dumbledore is preparing to recruit Remus Lupin, who was recommended by Harry, as a professor.

This brings up a new problem: what to do with Lupin's furry troubles.

In the original world, Catherine knew early on that Lupin had some problems because of Herpo, so Herpo would drool over him.

In Hailbo's impression, Catherine only forbade him to eat people and drool at people, but did not say that he was also prohibited from drooling at other things.

Werewolf...well, Catherine never thought that she would encounter a werewolf so soon.

In that world thousands of years ago, there were also werewolves, and they would infect ordinary wizards, but after systematic treatment, these wizards would most likely recover.

Snape has been busy with this matter recently. Severus has also read those books. He is also very interested in potions, so Catherine asked him to help Professor Snape.

This made Professor Snape look very unhappy for a long time.
