Mysterious Walker at Hogwarts

After returning to Hogwarts, Dean immediately went to the principal's office.

This time Dumbledore didn't shy away.

"Dean, if you are so anxious to see me, you must have gained something, right?" Dumbledore sat behind the table and stared at him expectantly.

"I'm not sure, so I hope you can help me." Dean said matter-of-factly.

"Tell me, maybe I can really help." Dumbledore said cheerfully.

"That's right, Professor, I hope you can let me borrow the Pensieve. I'm going to ask you to take a look at one of my memories." Dean said nervously.

Dumbledore looked at Dean quietly for several seconds before readily agreeing: "Well, I do think that being there will make it easier to discover some details that we usually don't notice."

After he finished speaking, he pointed to a cabinet next to him: "Dean, please weigh the old man and help me take out the pensieve from there."

"It's a great honor." Dean suppressed his inner excitement, walked slowly to the cabinet, and opened the cabinet door.

There was a shallow stone basin in the cabinet, with some strange letters and symbols carved on the mouth of the basin - Dean recognized them as some modified Saxon runes.

The pensieve was like a handicraft with a strong retro style, and it shone with silver light that made Dean's heart beat.

The silver light was emitted by the things in the basin. Dean had never seen anything like this.He couldn't figure out whether it was a liquid or a gas.It is like a piece of bright silver, but it is constantly flowing, like water ripples in the breeze, and like clouds, it spreads out and rotates softly.It was like light turning into liquid, or like wind turning into solid form - Dean knew that this was memory, the substance contained in the small bottle Lupine gave him.

After watching Dean place the pensieve on the table, Dumbledore suddenly asked: "Dean, do you know how to extract memories?"

"Can you teach me? Or help me extract it?" Dean asked.

"Dean, remember never let others touch your memory." After Dumbledore finished speaking seriously, he told Dean the method of extracting memory.

Dean tried to pull out the memory of using the past retrieval spell at the door of Lupin's house, and gently placed it in the pensieve.

"Let's go together." Dumbledore was not surprised at all that Dean succeeded in the first attempt, and took Dean into the pensieve with him.

"It seems that I care too little about Lupine. I didn't expect him to live in a place like this." After entering Dean's memory, Dumbledore looked around at the terrible environment around him and frowned.

"I thought you knew everything." Dean complained softly.

"Lupine is very cautious. Unless I keep an eye on him, it will be difficult to find where he is hiding." Dumbledore said softly.

"Professor, please pay attention there." Dean did not continue to dwell on this issue, but pointed to a trash can in the corner and said.

"You...are you talking about that mouse?" After reading the past retrieval spell, Dumbledore raised his eyebrows.

"I think it was the rat who betrayed Lupin," Dean said.

"Why do you think so?"

"Professor, that mouse should be Ron's long-lost pet Scabbers."

"I'm curious, why are you so sure?"

"If you look carefully, this mouse is exactly the same as Spot, except that its front paw is missing a toe." Dean reminded.

"This doesn't mean anything." Dumbledore looked at Dean meaningfully and said, "There may be many such rats in nature."

"You can ask Ron to identify it, he will definitely recognize it." Dean reminded.

"I don't think it would be wise to involve Weasley in this." Dumbledore had a good reason.

"...Okay." Dean was about to tell Dumbledore that Scabbers was Peter Pettigrew, but when he saw the look in Dumbledore's eyes, he suddenly understood. Dumbledore probably already knew what was going on. One thing, Peter Pettigrew should also be a part of his "Savior Training Plan".

"Have you warned Lupine to be careful of these little animals that are everywhere?" Dumbledore asked.

"I've warned him. I think he will be careful in the future."

"That's enough." Dumbledore took Dean out of the pensieve.

"I'm a little worried." After returning to the principal's office, Dean's mood seemed very low.

"What are you worried about?" Dumbledore seemed to have understood everything, "Worried about your friends being threatened?"

"Wouldn't it be possible?" Dean asked.

"Scabbers has lived in the Weasley family for many years and has never done anything out of the ordinary, so you should rest assured. Besides, aren't you right next to him? With you watching, what can he do?"

"Why don't you expose him now?" Dean asked.

"Evidence. Dean." Dumbledore reminded again, "No one will believe the testimony of a young wizard, let alone the self-defense of an Azkaban prisoner."

"As long as he shows his true colors..."

"I'm afraid it's difficult." Dumbledore shook his head. "As far as I know, Ron's pet returned to him not long ago. I'm afraid we don't have the chance to do this."

"You are the principal!"

"Even the principal cannot force a student's pet to be taken away." Dumbledore emphasized, "Otherwise, what difference is there between us and those evil people?"

"Do we have to wait until he does evil again before taking action?" Dean was very dissatisfied with Dumbledore's attitude.

"I think we should give him a chance to turn over a new leaf."

"But Sirius is still in Azkaban!" Dean said emotionally.

The reason why he wanted to find out Scabbers was because he wanted to take the opportunity to clear Sirius's grievances.

"Even if you expose Scabbers, I'm afraid it will be difficult to change Sirius's situation." Dumbledore suddenly became serious, "If this works, I swear that I will be the first to bring Scabbers to justice."

Dean opened his mouth and had nothing to say. It seemed that in the original book, Sirius never washed away his grievances until his death.

Because of the cowardice and incompetence of the Ministry of Magic, even if Peter Pettigrew is found out, it will not help. Instead, it may stimulate the Ministry of Magic to take drastic actions to cover up the scandal, such as giving Sirius a dementor's kiss to completely silence him, or killing him. Tighter guarding - which would make it doubly difficult for Sirius to escape from prison in the future.

Dumbledore must be thinking this way!Dean felt that he had grasped Dumbledore's train of thought.

"Okay, maybe I was wrong. After all, that was just the picture shown to us by the past retrieval spell. I did not catch the suspicious mouse." Dean changed the topic and compromised.

"Dean, I'm glad you realize this, but I still suggest you think carefully here and leave when you have thought it through." Dumbledore stood up and said, "I'm going to find Minerva. Some things have to be arranged.”
