After leaving the underground classroom, Kyle did not stop and walked all the way to the entrance hall.

Quite a few people have returned from Hogsmeade, and they are gathered here exchanging candies and joke props. It is much more lively than when they came here.

Kyle also saw two people standing next to the stairs.

Professor Lupin held a map in his hand and looked at it carefully.

"Very creative design..." He smiled and said, "When I was in school, I also saw an interesting map like this one, which can show the secret passages in the castle."

"Professor, you had this kind of map when you were in school?" Harry asked in surprise.

"Better than this..." Professor Lupin whispered, with a look of reminiscence on his face.

But soon, this reminiscence turned serious...

He looked at Harry and asked seriously, "Are there many maps like this in the castle?"

"There should be only this one." Harry said after thinking for a moment.

He remembered that Fred and George said that they made this map just for fun and had no intention of selling it as a commodity, and there was only this one.

After hearing what Harry said, Professor Lupin's expression eased a little.

"Professor, this is something I... picked up..." Harry didn't want to betray Fred and George, so he could only rack his brains to find an excuse that sounded reasonable to explain the origin of the map.

"I don't want to find out how you got hold of something like this, but I'm shocked you didn't turn it in, especially after the last time a student left the castle information lying around."

"I..." Harry wanted to explain, but didn't know how to start.

Fred and George had clearly told him before that he should destroy the map as soon as he wrote down the location of the secret passage, but he forgot about it.

So far, he only remembered the secret passage of the hunchback witch statue.

"I can't give it back to you, Harry." Professor Lupin put the map away. "I have to ..."

"Um?"

Suddenly, he moved his nose and seemed to smell a very familiar smell.

Professor Lupin searched for a while and happened to see Kyle who had just walked into the hall.

"Nice to meet you, Professor Lupin." Kyle smiled and waved.

"Hello... Kyle." Professor Lupin asked in confusion, "Why are you here? Why didn't you go to Hogsmeade?"

"I'm in detention, Professor." Kyle shrugged. "No time to go to Hogsmeade?"

"Confinement?!"

Professor Lupin was stunned for a moment. He had never expected that Kyle, who had been top of the grade for four consecutive years, would be put in detention.

But Harry acted very calm. He already knew about this when he met Kyle and Snape on the fourth floor in the morning.

As for Snape, there's nothing strange about it.

"He must have given you detention because it's Visiting Day at Hogsmeade," said Harry firmly.

"What did he ask you to do, deal with all that caterpillar slime?"

"No." Kyle shook his head, "It's not that bad. I just helped him make the potion for a few hours."

"Oh, that's okay." Harry said with lingering fear, "Last time I was put in detention by Snape, I didn't eat for several days in a row... By the way, what did you guys endure that took so long?"

"A rare potion..." Kyle said, "Wolfsbane Potion."

A trace of panic flashed across Professor Lupin's eyes, but it quickly disappeared. Although he tried to look normal, his hands were clenched tightly, fearing that Kyle would call out his name the next second.

This semester, he would take leave every full moon, and with the wolfsbane potion...it was difficult for him to guarantee that Kyle didn't discover anything.

Those were the people who had been visiting Hogsmeade, and now they were all back.

Fred and George came over and surrounded Kyle on the left and right.

"You don't know what you've been missing..."

"The Shrieking Shack wasn't as bad as we thought..." George said with a smile, "I don't know what Malfoy saw in there. He was so scared that he ran all the way back to the castle."

"We all heard his screams in Zuko..." Fred said regretfully, "But why didn't we see anything the last time we went there..."

Harry lowered his head and said nothing.

In fact, Malfoy was scared away by him. He was wearing an invisibility cloak and threw a ball of mud into the other person's face.

But because he used too much force, part of the invisibility cloak accidentally slipped off, revealing his head outside. It looked like he was floating in mid-air, which scared Malfoy away.

It was also for this reason that he was called to Snape's office.

Later, Connor, Cho and Cedric also came back.

Kyle ended the topic of confinement and followed them to the outside venue.

He estimated that if he stayed any longer, Professor Lupin would probably crush the map to pieces.

To be honest, he looked so nervous that it was almost as if the words "I am a werewolf" were written on his face.

Fortunately, Harry and Ron were there, because if it was Hermione, they would definitely notice something wrong.

But speaking of Hermione, it seems that we rarely see her recently, especially after the Christmas holidays, the trio has become a duo.

Only at mealtimes could one see Hermione carrying a bulging bag and hurriedly eating a few mouthfuls of food in the great hall.

Thinking of this, Kyle followed Kanna to the outside venue.

Qiu next to him handed over a bottle of butterbeer, and Kyle took it without thinking.

The next second, Butterbeer turned into an aggressive haddock and bit his arm.

The haddock was rubbery, not painful, but very firm, and no matter how hard Kyle shook it, he couldn't get it off, and pulling hard only made it longer.

Fred and George held their stomachs and laughed. It was obvious that it was their idea.

…

Watching several people walking out of the castle gate laughing and joking, Professor Lupin loosened his tightly clenched hands and a little color returned to his face.

Kyle didn't seem to notice anything, perhaps he was too nervous.

He thought so in his heart...

Yes, who would have thought that the great Professor Dumbledore would actually hire a werewolf as a professor, as if he would have agreed to let me go to school here before.

This kind of thing is impossible anywhere... Only Dumbledore...

Professor Lupin took a deep breath, gave Harry a few simple instructions, and then left in a hurry.

Now is not the time to think about these things, there is something more important to do.

He needed to go to Filch's place and find something.
