Mysterious Walker at Hogwarts

"Walking around in the castle at this time is a serious violation of school rules. You won't deduct points from me for this, right?" Dean said half-jokingly, somewhat resolving the awkward atmosphere.

Dean knew that it was impossible to extract the key name from Phineas today. He was determined not to tell him. It seemed that he had to find a way from the Black family's genealogy.

"Of course not." Dumbledore smiled and led Dean out of the principal's office.

"Shall we go to the Room of Requirement?" Dean felt that Dumbledore must have something very important to say to him, so the Room of Requirement is the safest.

"I'm afraid not, Severus occupies the place now; but we have another choice, don't we?" Dumbledore gestured to Dean.

"You mean...the room in the Mirror of Erised?" Dean asked in a low voice.

Dumbledore nodded imperceptibly and took Dean directly to the end of the corridor where the principal's office was, where a decorative curtain hung.

"Think of going to that room as if you were entering the Room of Requirement." Dumbledore whispered to Dean the secret to entry.

After Dean complied, he easily passed through the curtain and directly entered a small room with a huge floor-to-ceiling glass.

Dean could see beyond the glass to the room where the Mirror of Erised was.

"Very convenient, isn't it?" Dumbledore winked at Dean, "If someone breaks in here, I can directly intercept him instead of chasing after him - this is very effective in saving time."

Dumbledore led Dean directly towards the glass - it felt like walking through platform nine and three-quarters. In the blink of an eye, Dean found himself standing in front of the Mirror of Erised.

Dean took a sneak peek and found that Knightley was not there this time, but he was looking at something in his hand attentively.

Dean didn't see clearly what he was looking at in the mirror, but his attention was attracted by Dumbledore's words: "Thomas, I know you are very curious about your life experience, but I beg you not to bother Fei with this question anymore." Nias.”

Dean moved his eyes away from the Mirror of Erised and looked at Dumbledore: "Professor, I don't understand. Why did he refuse when you just need to tell me a name?"

"Phineas regards that as a lifelong disgrace, and he will never reveal it to you."

"Then do you know that name? Can you tell me?" Dean asked hopefully.

"Sorry, I'm afraid I can't say that. It's a family matter of the Black family. I don't want to and can't interfere." Dumbledore was silent for a moment before saying apologetically.

"I understand you." Dean muttered, "It seems that we can only place our hope on Lupine."

Dumbledore's ears twitched: "Did you just mention Lupin, Remus Lupin?"

"If you're talking about the werewolf nicknamed 'Moon Face,' I think we're talking about the same person." Dean hinted that he knew many of Lupin's secrets.

"When did you meet him?" Dumbledore asked.

"Sorry, I thought you knew it a long time ago, on the night when I dueled with that man for the first time." Dean was surprised that there was something that Dumbledore didn't know.

Dumbledore clearly helped him out in front of Snape that night.

"Dean, I once promised you that I would try not to interfere in your affairs, so I didn't delve into what happened after you and that person left Hogwarts. It seems that I made a small mistake. Me." Dumbledore said.

"After that man left, Mr. Lupine, who happened to turn into a werewolf on a full-moon night, was attracted by the smell of Wolfberry that he secretly placed on me, and then...I got to know him." Dean briefly explained their acquaintance. Lupine's passing.

"Did you ask Lupine to do something for you?" Dumbledore asked implicitly.

"I...I asked him to help me find the Black family's genealogy." After some hesitation, Dean decided to tell the truth.

"I see." Dumbledore nodded, "I think I understand."

"Understand what?"

"Thomas, do you know why I suddenly left Hogwarts just now?"

"Phineas said you received an urgent letter from the Ministry of Magic, so you left." Dean asked doubtfully, "Did something happen?"

"Someone from the Ministry of Magic wrote to tell me that a person tried to enter the old house of an ancient family." Dumbledore looked into Dean's eyes and said, "Unfortunately, that person is Remus Lupin."

"This is impossible! Lupine is by no means a reckless person, he will not do this, this must be a frame-up!" Dean shouted immediately.

"I and many people share the same view as you." Dumbledore said, "So as soon as the incident happened, my acquaintances at the Ministry of Magic sent me the letter, so I broke the appointment. I'm sorry. "

"What about the result? Is Lupine okay?" Dean asked eagerly.

"I rushed there in time and found Lupin before the Aurors." Dumbledore said, "Now I just need to find evidence to prove that Lupine just wanted to observe outside and did not enter the old house. The plan can successfully help him get out of trouble."

"Now that you have returned to Hogwarts, does that prove that this matter has been resolved?" Dean breathed a sigh of relief.

"Although it may be a bit inappropriate to say this - I still have some friendship with the Minister of Magic Fudge, and he sold me this face." Dumbledore said lightly, "I think you should have guessed what Lupine was trying to enter. Which old house is it?"

"Could it be the old mansion of the Black family?" Dean asked with a smile.

"No. 12 Grimmauld Place." Dumbledore's answer almost made Dean unsteady and fall to the ground.

If the Order of the Phoenix hadn't set up its headquarters there later because of this incident... it seems that history would have changed a bit.

Although Dean no longer cares about changing history, he feels that No. 12 Grimmauld Place still has extraordinary significance to the Order of the Phoenix, and such changes are not what he wants to see.

"There... won't be any problems there, right?" Dean didn't know how to express his worry.

"I said I got there early, so I used some necessary means." Dumbledore said implicitly, "At least for now, it's safe there."

"Then I'm relieved." Dean patted his chest. Since Dumbledore said this, his worries just now were unnecessary.

"I'm not as optimistic as you are, Thomas." Dumbledore said worriedly.

"What are you worried about?" Dean looked at Dumbledore with a question mark on his face.

"I had a brief chat with Lupine. I saw a very bad sign from him." Dumbledore said helplessly, "His adventure was largely due to your ask."
