Dunbulido took the Gryffindor students to the hall, and not long after, the students of the other three houses also arrived, and Dunbulido conjured a bunch of purple sleeping bags and left the hall.

"How did Blake break in?" Fred asked in a low voice, and the three of them dragged their sleeping bags into the corner,

"Maybe he really knows some secret passages?" Lawrence replied,

"I don't think he'll be able to hide from the Dementors." George guessed, "You know, he can escape from Azkaban, and there's no reason why he can't break through the Dementor-guarded entrance to the campus."

"It's going to be lights out—" Percy shouted, "go to sleep, don't talk—"

The candles all around were extinguished, leaving only the starry sky that the ceiling had turned into, and the ghosts that emitted a faint silvery-white light.

"I think Percy loves this job to death." Fred slipped into his sleeping bag and muttered, "It's a sign of his superiority, ha, student council president."

"The moon is so big today—" George rolled over in his sleeping bag and closed his eyes,

"Full moon—" Lawrence looked at the full moon that was just a few days away from the ceiling, and he wondered with some anxiety if he would be able to find Professor Lupin tomorrow. (Note 1)

───────

He guessed correctly, the next day, when he walked outside the office of Lupin's classroom, he saw a simple notice posted on the door, which stated that from the beginning of the week, Professor Lupin would be on leave for a week, and Defence Against the Dark Arts would be substituted by Professor Snape, Lawrence carefully recalled that the full moon nights in September and October happened to be weekends, and Professor Lupin was always very tired on the next Monday

And the portrait of the fat lady has also been replaced, the portrait of Sir Cadogan on the seventh floor has taken her place, and to the great headache of the prefects - they have received a lot of complaints from the students, Sir Cadogan is very fond of changing the secret language, and there is a tendency to be more and more exaggerated, for this Percy is very troubled, and the prefects can only take the trouble to tell the complaining students - because of Blake, so no other portrait is willing to take this position,

And before a Quidditch training, Harry came to Lawrence,

"Both Mr. Weasley and Professor McGonagall said Black was coming for me." Harry looked confused, "They all sound scared I'm going to find Black."

"Well, that's what I thought, Harry," Lawrence replied, "The point is, they don't know if they should tell you more or not."

"What else could there be?" Harry said with some displeasure, "Blake came looking for me, but no one told me why?"

"That's why I said it's up to you." Lawrence said seriously, "My proposal is still valid, are you going to listen to it now?"

"Hey, Harry, you're here—" Oliver. Wood interrupted their conversation by shouting, "It's time for us to go to training, there's big bad news."

"What's wrong?" Harry asked, distraught,

"I was going to talk about it together in training, and I'll tell you first if you asked," Oliver said, clenching his fists, "Slytherin made an excuse that Malfoy's hand hadn't healed yet, so our opponent on Saturday was Hufflepuff—"

"He's got his arm fine," Harry said angrily, "he's just pretending—"

"But we can't prove it," Oliver said sadly, "Let's go, I'm going to the stadium first, and you should hurry up, don't be late for training."

"I'd like to tell me after the game." Harry said irritably, "I don't want to hear any more bad news just yet."

───────

"It's crazy—" Lawrence muttered as he sat in the stands, the wind and rain making his vision gray, "How can this weather be better than Quidditch?"

"It's just this kind of weather, how can the game be suspended?" Jon asked Lawrence incredulously, "This is Quidditch—"

"Harry's glasses don't know if you can see it?" Hermione said worriedly,

"Gryffindor never thought about waterproofing?" Luna, who was sitting next to Ginny, suddenly asked, "Do you think Quidditch is just a sport on a broom?" (Note 3)

"Hey—" Ron said dissatisfied, "Listen, we're the team that practices the most, and we have a lot of tactics—"

"But it obviously doesn't work that way on a rainy day." Luna said, Ron looking at the crimson figure swaying in the wind and rain, his face flushed but he didn't know how to retort, "Or is your strategy for rainy days to fly in the wind and rain for a few hours every night?"

"Oh! I see—" Hermione jumped to her feet, her head down through the narrow passageway, and disappeared into the rainstorm,

"Hey—how?" Ron asked dissatisfied,

"How did Ravenclaw prepare for Quidditch?" Lawrence asked with interest, Luna tilted her head as if she didn't understand what he was asking, and Ginny giggled.

"Luna won't tell us how Ravenclaw prepares." Ginny replied with a smile,

"Ravenclaw will win the championship—" Luna said solemnly, Ron flailing his fist in indignation, and Ginny began to giggle again, "Since I didn't play against Ravenclaw, I'm rooting for Gryffindor now."

"Ha-oh, the game is suspended, I don't know which team called the timeout?" Lawrence laughed, Mrs. Hodge blew the whistle, and the players from both sides of the game flew back under their big umbrellas, "What's the score now?"

"Fifty to zero, we're ahead." Ginny replied, looking worriedly at the Gryffindor's umbrella, Lawrence knew she was probably worried about Harry,

"Where's Hermione?" Ron asked incomprehensibly, and Luna looked at him, as if studying some strange creature,

At this time, Mrs. Hooch blew the whistle again, and the game continued, and after a short while, Hermione squeezed back to them through the aisle with her cloak on,

"Where have you been?" Ron asked in a gruff voice,

"I'm going to cast a waterproof spell on Harry's glasses." Hermione said with some embarrassment, the cloak obviously didn't have that good waterproofing in the face of this kind of rainstorm, "I hope the game is over soon, I don't know how long the spell will last."

"Boom—" There was a thunderclap, lightning streaked across the sky, and a gray cloud drifted over at a very fast speed, Lawrence heard a warning bark from the stands behind him, he turned his head, it was a big black dog, Lawrence was stunned, from its gray eyes, Lawrence recognized it as the one in the screaming shack, it looked much better,

But to Lawrence's horror, he found that he had seen the dog before, but that time it was silvery white, and when he screamed at the shack, he was so thin that he didn't recognize it for a while, and it was exactly the same as the patronus of the big silver dog that Lawrence showed him in the third grade, Dunburydo, (Note 4)

"Blake?" Lawrence whispered, and he stood up,

"What's black?" Ron asked incomprehensibly, and then the cold air came towards everyone, and the happy mood of the Quidditch match disappeared, and the breath of despair seemed to stain the world with a layer of gray, and the crowd in the stands let out a few screams,

"Harry—" Hermione and Ginny screamed at the same time, Lawrence turned his head, and a crimson figure fell from the sky, it was Harry, and Lawrence recognized that the gray cloud was actually made up of a large group of Dementors' cloaks,

"Dementors—" Lawrence raised his wand, but someone was several steps faster than him, and Deng Bulido in the teacher's seat exuded an amazing sense of presence, making everyone look at him unconsciously, although some people may be far away from the teacher's seat, but everyone clearly felt that Dunburlido was angry, he was very angry,

Dunburidos raised his wand and waved, Harry, who fell from the air, slowed down and fell gently like a feather, and Dunburido's wand burst out with a dazzling white light, forming a huge light curtain, Lawrence stared closely at Dunburidos's spellcasting skills, Dunburlido was naturally able to cast a tangible Patronus, but obviously in this case, in order to protect everyone present, he deliberately displayed the Patronus in the form of a light curtain, but it took into account the power, so that the Dementors did not dare to continue to move, They could only slowly exit the court,

"Harry—is he alright?" Hermione tried her best to comfort Ginny, who was already crying, but she was crying herself, and her hat had fallen off to look up at the sky, and the rain mixed with tears.

"Oh, it's alright, it's alright—" Luna was the calmest of the kind, trying to comfort Hermione and Ginny, but the rain had made their long hair soaking wet and looking very embarrassed,

Mrs. Hodge blew the whistle again, but this time not a timeout, but the whistle at the end of the game, and it was Cedric, the new captain of Hufflepuff and a Seeker, who caught the Golden Snitch. Diggory, Hufflepuff won one hundred and fifty to fifty, but not many people cheered, the influence of the Dementors was still there, and Gryffindor's Harry. Potter's life and death are unknown,

"Ron, Ron, umbrella—" Lawrence shouted to the stunned Ron, which woke him up from a dream, and Lawrence and Ron scrambled to hold up the umbrella, and then they pulled Hermione and Ginny up and walked out of the court with the crowd,

"Luna, what are you doing there? Let's go—" Lawrence called out to Luna, who was still sitting there, and Luna stood up in some surprise,

"I've always been used to walking alone." Walking on the dirt road, Luna suddenly said, "Are all friends like this?"

"Ginny? Oh, yes," Lawrence said of Ginny before remembering that in last few Quidditch matches, Luna wasn't defeated by Tom. Riddle was in control, and Ginny was in the hospital room, and he replied with some uncertainty, "I guess most of that is, right?"

"Did you just say Blake?" Luna asked again, "I mean, it's Black, not Black, you know what I mean." (Note 5)

It was a difficult question to answer, and before Lawrence could figure out how to answer it, Luna continued,

"You don't have to say what you don't want to say," Luna looked left and right to see if anyone was paying attention to them, "Friends can leave the court together, but I think we still need some**?"

"Huh." Lawrence laughed from Sirius. Blake was able to break into the campus, and he was probably sure that Professor Lupin hadn't told Dunbulido all the secret passages, and he planned to talk to Professor Lupin tomorrow. (Note 6)

───────

Note 1: In the original book, on Halloween, Lupin says to Snape, 'I'm going to need some more tomorrow.'" , the wolf poison potion needs to be taken the previous week.

Note 2: I specifically looked through the calendar of 1993, and then I was more sure that the full moon time in "Harry Potter" was different from reality, because the first day of September of that year was the full moon, so I thought I didn't need to follow the real full moon time and just match the content in the book.

Note 3: Luna is very good at asking embarrassing questions or telling embarrassing facts.

Note 4: Just like Professor McGonagall, her Patronus is a cat with a tabby pattern.

Note 5: Black (Black), Black (black).

Note 6: Lawrence was still destined to find no one because there were no classes on Saturdays and Sundays.

Note 7: Change Error: From Sybil. Trelawney's first time in class knew that October 16 was Friday, so October 31 was Saturday and November 1 the next day, so I had to ask Lupin to take a week off.
