After leaving the school hospital, Felix stood in front of the window of the castle corridor and saw the little wizards who came back from the holiday appearing from under the long ramp. Even if he couldn't hear the sound, he could imagine their excited conversation from his body movements.

"School will start tomorrow. I'd better ask Percy Weasley at the dinner party, eleven or two years. It's hard not to make people think about it..." Felix said to himself: "There is also the conversation between Dumbledore and Lupin. Although there is no way to know the specific details, you can judge one or two by looking at the principal's subsequent behavior."

"I seem to be stepping on a key node of a drama. Next, is it an ordinary ending or a shocking reversal?"

"Felix"

Professor McGonagall's voice came from the other side of the corridor, her steps were rushing, and the hem of her robe floated behind her.

"My patron saint didn't find you..." She walked to Felix, her chest fluttered violently, and she said quickly: "Dumbledore arranged a series of tasks. Hager and Snape went to the station to pick up students, Frieve went to modify the magic of the school wall, and several secret passages that needed to be temporarily sealed... He himself was going to meet the leader of the horse."

Felix's heart moved, and he asked tentatively: "Did Principal Dumbledore mention the orders about rats?"

"Oh," Professor McGonagall looked at him weirdly: "Dumbledore said you might know that I don't have to hide it from you. But it's better not to spread it."

"I'm going to the school hospital and the common room to see if Weasley's rat is still there. Oh my God, when Dumbledore told me I couldn't believe it, it could be Animagus, who might be a dark wizard."

"What can I do, Minerva?"

"There are two secret passages directly connecting Hogsmeade in the castle, and you need your help to block it..."

Later, in the staff lounge next to the auditorium, Felix met Dumbledore again, and he was talking closely with Professor McGonagall, with their faces very serious.

"Percy Weasley told me that it was twelve years..."

In addition to McGonagall, he also saw Lupin, who had not seen for a long time. He looked tired and looked even more tired.

Professor McGonagall was also reporting on the tasks assigned by Dumbledore, "...Hagher and Snape completed the task well, and there was no accident in between, and Flivie would take some time. As for the seven secret passages, four of them were sealed very early, and the other three secret passages, let me ignore the beating Liu, and the remaining two." She looked at Felix.

Felix said: "The one-eyed witch statue on the fourth floor of the castle has been closed by casting, and the one behind the mirror on the fifth floor collapsed."

After a brief pause, he couldn't help asking: "Dumbledore, I don't understand. Are you worried that Black will come in through the secret passage? Why don't we use this to set up a trap?"

Dumbledore shook his head gently, "The risk is too great. They are directly connected to the inside of the castle. I left the secret passage of the beaten man on the edge of the Forbidden Forest. Maybe the trace of Black can be found."

He looked at the three people present and said in a low voice: "I don't want too many people to know until the truth comes to light. One of you, one is too entangled with the past, the other is my trusted deputy, and the other may have found clues..."

"I want to tell you: Sirius Black betrayed the Porter couple in doubt because the Petr, who was suspected to have been killed by him, may have been alive all the time, and even lived in the Weasley's house as Ron Weasley's pet, the mouse-spotted man.

McGonagall exclaimed, "Oh my God! Is it true? Albus, you told me that it was a black wizard..."

Lupin looked at Felix with a calm and calm look on his face, without any surprise. As Dumbledore said, Felix Hepp is a very keen person. Is this Slytherin's most outstanding student in recent decades?

Half a semester has passed, and he has a certain understanding of this scary young professor. When he first learned about Felix's performance in school, he almost fell off his chin.

This is much exaggerated than what they did back then, including the duel that caused a sensation in the wizarding world. He also heard a more complete version. Since then, he has stayed away from Felix. He feels that if he contacts a few more times, his identity may be discovered...

Dumbledore replied softly: "I'm not sure, Minerva. The two most critical people, Black is still on the run, the rats are gone, and he may even never return..."

Lupin interrupted: "The possibility is very low. I know him. If the mouse is really Peter, he would wait and see in a place that he thinks is safe and will not show up until things develop in line with his expectations."

Dumbledore nodded and said, "This is also the reason why I don't want to make the secret public. In addition to the lack of evidence, I actually look forward to Ron Weasley's pet jumping out by itself, which will save us a lot of time."

Professor McGonagall asked uneasily: "Abus, do we want to tell Potter and the others?"

"It's better not." Dumbledore rejected her proposal. "Minerva, every time there are more people who know the secret, the risk of leaking news will increase tenfold. Moreover, as long as Potter and his team expose their feet slightly, we may never see the mouse again."

He paused, "And the worst possible is that mice will hurt them."

Felix suggested: "Perhaps some of the news can be revealed to Miss Granger. We can't always stare at them, and based on my knowledge of these three students, they are likely to investigate on their own."

Dumbledore showed a distressed expression: "This is indeed a problem, Felix, you are familiar enough with Miss Granger. Do you think she can do this task?"

"I don't think there is anything wrong," Felix glanced at Lupin, "she was good at discovering the truth and keeping secrets."

At the end of this brief conversation, Lupin couldn't help but ask Dumbledore, "Can we inform the Ministry of Magic to show mercy when facing Sirius..."

"For what reason?" Dumbledore asked, his azure blue eyes shining in the dim room.

"All of the above is based on assumptions, our guess about existing questions, but Black is always the secret agent of the Porter couple, and you agree with this, Remus? I provided this key testimony to the Ministry of Magic that year. According to the information I received, he did not make any excuses in the private interrogation, so I was completely disappointed with him..."

"We have no evidence, and it's hard for the Ministry of Magic to adopt your testimony with just a picture of an ordinary mouse, and once they know you," Dumbledore said, "Your words will be greatly reduced."

Lupin's expression dimmed. If he wanted to testify, he would have to tell what happened back then. His werewolf identity was no exception. The entire magic world knew what the Ministry of Magic was about werewolf attitudes.

"Remus, we have done our best we can."

At the end of the briefing, Professor McGonagall and Lupin both left, "Felix" Dumbledore called him from behind, and Felix looked at the principal in confusion.

"If you catch Black I have no doubt about this, I hope you can control him and not let others know, especially Severus and the Ministry of Magic."

"I understand the Ministry of Magic, but Professor Snape"

"The misunderstanding between them is too deep, and I'm worried that Severus will do something irrational." Dumbledore showed exhaustion for the first time. "I have to think more, Felix."

"...I promise you, principal."

Felix turned and left the staff lounge. The lively noise in the auditorium formed waves of sound. Everyone chatted loudly with excitement. He saw Fred and George knocking on the goblet and empty plates with knife and fork, making a crisp sound.

...

The banquet ended with laughter and joy. Felix returned to his office and reviewed what happened today in his mind. He found that the key to the whole thing was Sirius Black and the mouse. As long as he grasped one, the dusty truth would be revealed to the world.

He shook his head, and it would be better to consider teaching in the new semester. The magic of the Thinking House has undergone earth-shaking changes, which gave him a good idea.
