Mysterious Walker at Hogwarts

"What are you doing here?" On his way back to the Gryffindor common room, Dean caught a glimpse of the Weasley twins wandering near the Headmaster's Office.

"Hey, Dean, why are you back so late? Are you lost again?" One of the twins greeted loudly.

The other twin took the opportunity to stuff something into his arms.

"George, don't interrupt; Fred, what are you hiding?" Dean asked.

The twins' eyes widened in shock, not so much that Dean could detect their little movements, but that he could actually tell them apart.

"Why are you looking at me like that?" Dean was a little confused.

"Dean, how did you do that?" George raised his eyebrows.

"Fred's actions are so obvious, and I'm not blind."

"No, I mean how do you tell us apart?" George exclaimed, "even our mothers often admit their mistakes."

"Well, intuition." Dean replied. There is no reason, he just knows who is who. Maybe this is also a talent?

"I understand, it's vision!" Fred said a little depressed, "Professor Trelawney can correctly distinguish the two of us, which is why we haven't given up the divination class yet."

"What he means is that at least from this point of view, Professor Trelawney proves that she is not completely a liar." George explained.

"Tch~ Don't think that I don't know what you are thinking. You just want to cause some mischief in the Divination class - Professor Trelawney is one of the few professors who will not deduct points for causing trouble in class. ." Dean revealed unceremoniously.

By completing "Mission: Naughty Bag's Favor", Dean has found the correct way to get along with the twins, that is, don't treat them as outsiders as much as possible, so that they will feel that you are one of their own.

"Oh, no, you are always so sharp and... ruthless." George clutched his chest as if hurt.

"Stop interrupting, what were you going to do just now? Are you going to tease Filch again?" Dean asked.

Ever since he gave Filch a harsh lesson when he first entered school, the old Squib had behaved extremely well in Dean's eyes and almost never appeared in Dean's sight.

If the potion that turns a squib into a real wizard can be formulated in the future, Dean is even considering giving Filch a try.

Of course, he would never admit that he was actually planning to use Filch as a test drug.

"No, we found something more interesting." George winked at Dean.

"Oh?" Dean's interest was piqued. He had been under a lot of pressure recently and wanted to find a chance to relax.

"We found two Dumbledores in the castle." Fred also came over.

"This is impossible!" Dean retorted subconsciously.

In fact, he knew in his heart that this was not impossible. For example, the Dumbledore he saw tonight was very abnormal. If it was the "other" Dumbledore, it seemed to make sense.

"We have evidence~" Fred said mysteriously.

"What evidence?"

"Here's the evidence~" Fred said and took out something from his arms, which was exactly the same thing that Dean had seen before.

It was a large, square, very old piece of parchment with nothing written on it.

"The Marauder's Map?" Dean couldn't help blurting out. What he was most worried about happened.

Due to the hopelessly long learning progress bar, despite practicing diligently, he has yet to master and activate the Concealment Spell, and the presence of the Marauder's Map may expose him as the Secret Walker at any time.

You must get the Marauder's Map. At least until you have completely mastered the concealment spell, this treasure cannot fall into the hands of others!

Dean made his decision almost immediately.

"How do you know this is the Marauder's Map?" the twins said in surprise.

"First tell me when you got it." Dean prayed that it wouldn't be too long before they got the Marauder's Map, otherwise they might have discovered something.

"It didn't take long. To be precise, it was the second night after you and Ron were hospitalized. That night, all the professors disappeared. As a result, the routine patrols of the prefects became very lax." Fred was the fastest said, earning a disapproving glance from George.

Fortunately, it didn't take long for Dean to breathe a sigh of relief.

After that day, he only pretended to be a Mysterious Walker once when he got the dragon egg from Quirrell, and the chance of being discovered by the twins was low.

"I understand, the castle was not very peaceful that night, so you went to Filch's office to 'get' the Marauder's Map, right?" Dean asked.

A lot happened that night. Quirrell made an appointment with the Mysterious Walker and gave him two Mysterious Shards stolen from Umbridge; Dean took the opportunity to pass the Philosopher's Stone test; and then went to meet Dumbledore on the suggestion Grindelwald

Dean's rash break-in diverted all the professors' attraction, including Filch and Mrs. Norris, giving the twins a chance to sneak in.

But the students didn't know what happened, except that the night patrol was light that night and the professors didn't show up.

Apparently the twins gained a lot that night and got the Marauder's Map.

"You predicted everything." Fred said frustratedly.

"It's not a prophecy, it's a speculation. In fact, I was going to take advantage of the lax patrol that night to retrieve the Marauder's Map from Filch. Unfortunately, my luck was not as good as yours, and I met Snee on the road. Professor Pu." Dean explained.

"I understand, you're a fool~" Fred smiled narrowly.

"Get it back? You mean this map was originally yours?" George noticed Dean's words.

"I got this by chance, but unfortunately it was accidentally confiscated by Filch." Dean weaved a lie carefully.If someone really checked, he could blame Newt, but Newt gave him a map anyway.

However, Dean felt that no one would really go to Newt and Filch for verification. The only possible candidate, Dumbledore, would probably prefer the Marauder's Map to fall into the hands of him rather than the twins.

"How can you prove the map is yours?" Fred asked.

"Sorry, he doesn't mean to doubt, but you have to come up with some evidence." George explained.

"It's easy." Dean took out his wand, touched the parchment lightly and said, "I solemnly swear that I did nothing good."

Thin lines of ink, as thin as a spider's web, immediately began to appear where the wand had just touched.These lines meet and cross each other, extending to every corner of the parchment.

This map shows all the details of Hogwarts Castle and its various grounds.But the really remarkable things are the tiny dots of ink that move along the map, each labeled with a name in tiny letters.

Finally, writing began to appear on the top of the parchment. They were large, curved green characters. They were: Supplier of Auxiliary Materials to Magical Prank Makers. Gentlemen Moony, Wormtail, Padfoot and Prongs proudly presented the Marauder's Map.
