However, in reality, Harry did not have a chance to speak to Mr. Weasley after arriving at the Burrow, and he worked at the Ministry of Magic for long hours every day until Christmas Eve.

The Weasleys and their guests sit in the living room, and Ginny decorates the room in such an exaggerated way that it resembles a sea of latte paper.

Fred, George, Harry, and Ron are the only ones who know that the angel at the top of the Christmas tree is actually a goblin who is bitten by Fred while plucking turnips for the Christmas dinner. So they cast a stun spell on it, painted it gold, dressed it in a miniature tutu and glued a pair of wings to its back, and were now glaring down at all of them in anger.

It had a large bald head like a potato and shaggy feet, the most ugly angel Harry had ever seen.

They were all listening to Mrs. Weasley's favorite singer, Selistina Warbeck, on Christmas radio, her melodious singing voice coming out of a huge wooden radio.

Fleur seemed to find Celestina's singing voice boring, and she spoke in the corner with a loud voice, while the sullen Mrs. Weasley kept pointing her wand at the volume controller, so Celestina's voice became louder and louder. In a jazz-style rhyme, 'The Crucible of Intense Love', Fred and George begin to play with Ginny and explode. Ron kept sneaking a peek at Bill and Fleur, as if to learn some tricks.

Lupin, meanwhile, sat by the fire and stared into the deepest part of the fire, as if he couldn't hear Celestina's voice.

"Oh, come and stir my crucible, and if you do nothing wrong, I will kindle a strong fire of love so that you can spend the night warmly. ”

"We danced to this song when we were 8 years old!" Mrs. Weasley wiped tears from her eyes with her sweater. "Do you remember, Arthur?"

"Huh?" Mr. Weasley, who was peeling tangerine, nodded and said, "Oh, yes...... Incredible tune...... "He struggled to sit up straight, and turned his head to look at Harry, who was sitting next to him.

"I'm sorry," he said, glancing over the radio, where Celestina had already sung the chorus, "and it's almost over." ”

"It's okay," Harry grinned. "Has the Ministry of Magic been busy lately?"

"Very busy," said Mr. Weasley, "I wouldn't care if there was progress, but I suspect that none of the three arrests in recent months have been a real Death Eater - just don't tell anyone else, Harry." ”

Suddenly, he seemed much more alert. "They didn't detain Stan, did they?" asked Harry.

"I'm afraid not," Mr. Weasley said. "I know Dumbledore tried to ask Scrimgeour directly to release Stan...... I mean, everyone who interrogated him agreed that Stan couldn't be a Death Eater...... But the top brass wants people to see their progress, and 'three arrests' is better than 'three wrongful arrests and releases'...... Again, it's all top secret......"

"I'm not going to say anything," Harry said. He hesitated for a moment, not knowing how to speak, and as he gathered his thoughts, he listened to Celestina Warbeck start a new song, "You have enchanted my heart."

"Mr. Weasley, do you remember what I told you before I left for school at the station?"

"I've checked, Harry," Mr. Weasley said immediately. "I went and searched Malfoy's house. Nothing was found that shouldn't have been there, broken or intact. ”

"yes, I know, I read in the Daily Prophet that you've looked it up...... But that's a different story...... Well, further ......" He told Mr. Weasley all the conversation he had overheard between Malfoy and Snape and the subsequent argument between Harry and Van Lin, and as Harry spoke, he saw Lupin's head turn slightly to his side, hearing every word. When he had finished, no one in the room spoke except for Selistina's soulful humming.

"Oh, where did my poor heart go, and it abandoned me for a spell......"

"As Van Lin said, have you ever thought, Harry," Mr. Weasley asked, "Snape is just pretending—"

"But there must be something between them. I know the unbreakable oath and Snape has no reason to ......"

"No, I think he would. Lupin said blandly, "I trust him." ”

"You trust him?" Harry thought incredulous, looking straight at Lupin.

"—do you really like or trust Snape?"

"I neither like nor hate Severus," Lupin said.

"No, Harry, I'm telling the truth," he added, seeing Harry's skeptical expression. "We may never be close friends, and after all that happened between Jaime and Sirius and Severus, there was so much bitterness. But I haven't forgotten my year at Hogwarts, where Severus made the perfect potion of wolf poison for me every month, so that I didn't have to suffer so much during the full moon. ”

"But he 'accidentally' leaked the fact that you were a werewolf, causing you to have to leave!" Harry said angrily.

Lupin shrugged. "Sooner or later, this will leak out. You and I both know he wants my job, but if he wants to do me more harm, he can do it in the potion. But he kept me healthy. I should be grateful to him. ”

"Maybe he wouldn't dare do anything in the potion under Dumbledore's nose!" Harry said.

"You've made up your mind to hate him, Harry," Lupin smiled feebly. "I understand, Jaime is your father, Sirius is your godfather, and you have inherited your prejudices. You can tell Dumbledore everything you said to Arthur and me, but don't expect him to agree with you, or even expect him to be surprised by what you say. Maybe Dumbledore ordered Severus to question Draco. ”

“...... Now that you've torn my heart apart, I thank you for giving it back to me!" Celestina ended her song with a long high note, and the radio erupted in loud applause, and Mrs. Weasley enthusiastically joined in.

"Is it over?" exclaimed Fleur. "Thank goodness, how terrible-"

"Shall we, then, have a nightcap?" asked Mrs. Weasley, leaping to her feet. "Who wants eggnog?"

"What have you been up to lately?" Harry asked Lupin as Mrs. Weasley hurried to get the eggnog and the others stretched out and started talking.

"Oh, I've been working in secret," Lupin said. "No exaggeration. That's why I can't write to you, Harry; ”

"What do you mean?"

"I've always lived with my companions, my kind," Lupin said.

"Werewolf," Lupin added, seeing Harry looking at him puzzled. "They're almost all on Voldemort's side. Dumbledore wanted a spy, and I was...... Ready-made, and we've done that a long time ago, to get that vampire out, and then Van Lin destroyed the entrance to the underground street. ”

"Underground mall?" Harry asked, "is that ......?"

"Werewolf territory. "In fact, almost all of the werewolves are on Voldemort's side, and they have made some moves......

"How could they like Voldemort?" asked Harry, puzzled.

"They think they can get better under his rule," Mr. Lupin said. "And it's very difficult to fight against Greyback......"

"Greyback?" exclaimed Harry, "that's not ......"

"Oh yes, Fenrir Greyback is probably the most brutal werewolf in existence. His goal is to bite and infect as many people as possible, and he wants to create enough werewolves to conquer wizards. Voldemort promised to give him some sacrifices in return for his service. Greyback specializes in biting small children...... He said that he would bite them as children, so that they would grow up away from their parents and grow up with hatred for normal wizards, and that Voldemort had threatened others by letting him out to bite their children, and that threats often worked. Lupin paused, then said, "It was Greyback who bit me." ”

Even though Harry knew something, Harry couldn't help it......

Lupin is fighting with the werewolf who ruined his life.

It seemed to see Harry's shock, or some other emotion, but Lupin didn't seem to care that much, as if he was telling someone else's story.

"Yes. My father offended him. For a long time I didn't know the identity of the werewolf who attacked me, and I even sympathized with him, thinking that he couldn't control himself, and understood what it was like to be shapeshifted. But that's not the case with Greyback. During the full moon, he approaches his victim to make sure he is close enough to attack.

Everything was planned by him. Voldemort used him to organize and lead the werewolves.

I can't say how much progress has been made in Greyback with his own unique and reasonable views, but he still insists that blood is deserved by us werewolves, and that we should take revenge on normal people. ”

"Revenge?"

"It probably has something to do with Greyback's character, but ......," Lupin paused, "I have to change their minds, and Rutherford has helped me a lot in that." ”

"Help?" Harry remembered the vampire who had spoken out at the ball, "I don't think it'......"

"That's just their opinion, Harry. "It cannot be denied that werewolves should use werewolf practices." ”

"What do werewolves do?"

"Domination!" said Lupin, "a good way to take everything from Greyback, purify your bloodline, and then control all the werewolves...... There is always a need for a wolf in a pack. ”

"Domination, head wolf?" Harry felt a little unreliable, glancing at Lupin's emaciated body......

"I'm sorry, but I think ......"

"How do you think of me, not looking like a leader?" Lupin said nonchalantly, "Jaime said the same, but he thinks I'm still strong after the transformation. ”

At the mention of his friend, Lupin's mood seemed to be a little relaxed.

He took a glass of eggnog from Mrs. Weasley and said thank you. Looks a little happier. At the same time, Harry felt a surge of excitement: Lupin had just mentioned his father, which reminded Harry that he had something else to ask Lupin.

"Have you ever heard of someone called the Half-Blood Prince?"

"Half-breed what?"

"Prince," Harry watched him closely, hoping to see the signs he remembered.

"No prince is a wizard," Lupin said with a smile. "Is this a title you're going to adopt? I thought 'True Son' would be enough. ”

"It has nothing to do with me!" said Harry, dissatisfied. "The Half-Blood Prince is a man who studied at Hogwarts, and I got his old Potions textbook. The book was full of spells written by him, spells he invented. One of them is the upside-down Admiralty—"

"Oh, that spell was very popular when I was at Hogwarts," Lupin said nostalgically. "It was a few months when I was in fifth grade, and you were caught under this spell and you would be lifted to the air by your ankle. ”

"My dad used it," Harry said. "I've seen it in the meditation basin, he used it for Snape. He tried to say it casually, as if it were an inconsequential comment, but he wasn't sure if it had the desired effect, and Lupin's smile seemed a little too understanding.

"Yes," he said, "but he's not the only one using it." As I said, it's very popular...... You know how these spells come and go......"

"But it sounds like it was invented during the time you were in school," Harry insisted.

"Not necessarily," Lupin said. "The popularity and obsolescence of spells are like everything else. He looked into Harry's face and said calmly, "Jaime is a pureblood, Harry, and I assure you that he never made us call him 'Prince'. ”

Harry suddenly threw away his disguise and said, "Isn't it Sirius or you?"

"Absolutely not. ”

Harry stared at the fire. "I just think- well, he helped me a lot in Potions class, that prince. ”

"How old is that book, Harry?"

"I don't know, I haven't checked. ”

"Well, maybe this will help you find some clues as to when the prince went to Hogwarts. Lupin said.

As soon as she said this, Fleur decided to imitate Celestina and sang "The Crucible of Intense Love", and everyone knew it was time to go to bed after catching a glimpse of Mrs. Weasley's face.

Harry, in fact, was not reluctant, but challenged Mrs. Weasley's rant?

It was certain that Mrs. Weasley wouldn't treat her like that, but in fact, it made Harry feel very uncomfortable.

After saying goodbye to Lupin, Harry and Ron climbed all the way to Ron's attic bedroom, where a camping bed had been added for Harry. Ron immediately fell asleep, but Harry dug through his suitcase for Advanced Potions Preparation before going to bed.

Following Lupin's prompt, Harry flipped through the pages and searched for it, finally finding the publication date at the beginning of the book.

This book was written almost 50 years ago. His father and his father's friends hadn't been to Hogwarts 50 years ago.

Momentarily disappointed, Harry tossed the book back into the box, turned off the light, and turned over to consider Lupin's return to the Werewolf Clan and Snape, Malfoy, Stan Sampak, and the Half-Blood Prince.

Oh, of course, and Van Lin, in fact, Harry was once again abandoned, and only he and Ron returned to the Burrow.

Eventually, Harry fell asleep uncomfortably, dreaming of crawling shadows and the cries of bitten children.
