Harry, Ron and Hermione looked confused, they didn't know what Snape was talking about.
Lupine seemed to be the same, but Ivan still noticed a slight change in the corner of his eyes.
"Severus, do you mean that Harry got it from Mr. Wormtail or one of these people?" Lupine turned and said softly, "Harry, you know these person?"
"I don't know!" Harry said quickly.
"See, Severus, it looks to me like a product of Zonko's Magic Joke Shop," Lupine said, turning to Snape.
"It's us!" Fred and George rushed in from the crowd, and they explained to Lupine and Snape, "We bought this parchment from Zonko's Magic Joke Shop a few years ago, and we just Give it to Harry."
"Very well, everything is clear!" Professor Lupine said happily, "Harry and the others did not violate the school rules, he was just showing this prank parchment to his friends! In my opinion, he simply I don't want to be known by the professors... "
"Lupine!" Snape said in a low voice, taking a step forward, "Don't be stupid, you and I both know what this parchment is."
"Obviously, as I said just now, this is a prank product, and it will insult anyone who wants to read it." Professor Lupine blinked.
"Not this one, I've seen it before..."
Snape stopped suddenly, looking angrily at the innocent Lupine.
Although he saw this piece of parchment more than once from his old enemy James Potter when he was a student at Hogwarts, he really didn't know what this piece of parchment was, nor did he know how to use it , The four of them were very defensive against themselves.
Since Lupine didn't want to say anything, there was no point in continuing the stalemate, and Snape didn't want to discuss his student days in front of the whole school.
"Very well, Lupine!" Snape returned to his usual very unpleasant tone, and he sneered, "It suddenly occurred to me that the beginning of tonight happens to be a full moon, I hope you will Stay alone in the house, don’t forget to lock the door! By the way, I will send your potion later, and we can talk about pleasant topics related to this parchment.”
Snape looked at Lupine with malicious eyes. He deliberately added the accent to the words night, full moon, and locked door, as if to give everyone some kind of hint.
"No problem, my door is always open for you, Severus!" Professor Lupine said briskly, "And, thank you for the potion."
"You're welcome." Snape didn't have a smile on his face, he looked at Lupine, Harry, and Irving viciously, and continued with his eyes narrowed, "I made a whole pot, if you want If so, just tell me."
"I started drinking it a week ago, and a little more this afternoon should be enough!" Professor Lupine turned his head to look at Ivan and the others, "Harry, Ivan, Ron, Hermione, you and I Come on, I have something to tell you about the homework you gave me... "
Professor Lupine took two steps forward, seeming to remember something, "Severus, you don't mind if I take this away?!"
Snape didn't speak, but judging from his gloomy face, he obviously minded.
Lupine pretended not to see Snape's expression, he quickly stepped forward, picked up the Marauder's Map from the dining table, and stuffed it into his robe.
Ivan and the four of them left the auditorium closely behind Professor Lupine, and no one dared to look back at Snape.
It was not until the hall that they dared to speak.
"Professor, we..." said Harry quickly, as though he wanted to get the Marauder's Map back from Lupine.
"I don't want to hear an explanation, Harry!" Lupine looked around the empty foyer, the other students were still in the auditorium, and there was no one else around except them, he said in a low voice, "Actually, I I just learned that this map was confiscated by Mr. Filch many years ago, and I recognize it."
Harry and Hermione looked at him with interest, Ron lowered his head in deep thought, wondering what he was thinking, and Ivan covered his forehead weakly.
Professor Lupine not only knew this map, he was also one of the makers of the Marauder's Map.
Harry was so unlucky that Professor Lupine found out that it was useless the first time he got it, and he would definitely not give the map to Harry again.
"I don't want to know how you guys got it, I'm surprised you didn't intend to turn it in, especially since Sirius is still lurking around the castle!" Lupine turned his head and looked at Hermione, "This You've done something very wrong, Hermione, and I thought you'd be more sensible than the three of them. "
"Don't blame Hermione, she just persuaded me to hand in this thing." Harry asked curiously, "Professor, why do you know this map?"
"It's not something you're supposed to know, Harry." From the way Lupine looked, he didn't seem to want to say much on the subject.
"Okay, so why would Snape think I got it from the maker?" Harry continued asking not to be outdone.
"That's because..." Lupine hesitated. "Because the people who made the map were probably trying to lure you out of school. They thought it would be fun."
"Moon face, Padfoot, prongs and Wormtail?" Ivan interjected at the right time.
It turned out that after the four of them graduated, the reason why this map would fall into Filch's hands was because they kept it in the school on purpose.
From this point of view, James Potter, Sirius Black, Peter Pettigrew, and Professor Lupine in their school days must have been as mischievous and troublesome to Filch as Fred and George are now.
"Yes, that's them." Lupine nodded.
"Professor, do you know them?" Harry asked, eagerly.
"We've met before," Lupine replied curtly, looking at Harry more seriously than usual.
"Wait a minute, professor, about this map." Ivan asked in a hasty tone, "Since you know it, you must know how it was made, right?"
"Well, this requires a very advanced knowledge of magic, not your age..."
"Professor, I don't want to know the specific method of making this map." Ivan continued, "You just need to tell me how the four people, Moon Face, Padfoot, Prongs, and Wormtail got the magic power of making this map source, which, in my opinion, requires very powerful magic."
Professor Lupine looked at Ivan in astonishment, Harry, Ron, and Hermione also looked at him in surprise, wondering why Ivan would suddenly ask such a question.
