Like a knife, the words seemed to be able to cut through the heart.

Sirius's eyes immediately became sharp, staring at Harry fiercely: "Are you Snape? Have you drunk the Polyjuice Potion?"

"You bastard, you disgusting slug, you dirty dog... you rat."

"You've turned into James' child. Oh, you can't have Lily, and your heart has become twisted. Are you going to do something to Harry?"

"Disgusting, vile, despicable..."

He cursed fluently and struggled hard, his eyes were fierce, and he wished he could kill the "Snape" in front of him with his eyes.

"My dear godfather, calm down." Harry shook his head. "Given your relationship with Professor Snape, I'm afraid he can't call you 'godfather'."

Sirius was stunned.

That seems to be the case...

"I know what you're trying to do," Harry went on. "Is it about Peter Pettigrew?"

Sirius nodded dumbly.

He was very surprised.

This news...

How did Harry know that?

"The secret keeper of Potter's old house was not you, but him?" Harry asked.

Sirius nodded numbly again.

He also knew the news.

Animagus could still be explained by Lupin, but no one else alive knew about this news except himself and Peter.

"Peter has been caught by me." Harry said in a gentle tone, throwing out a piece of news.

Sirius nodded numbly out of habit and said "Oh". After a while, he realized the meaning of this sentence. He suddenly raised his head and stared at Harry with disbelief in his eyes.

"Peter? Peter Pettigrew?" His voice was hoarse, like a sharp wind sweeping through dead wood.

Harry nodded, "Yes, Wormtail, Peter Pettigrew, the man who betrayed my father. He used the Animagus to become the Weasley family's pet and hid for thirteen years."

Sirius felt his mouth dislocate.

The man in front of him looked a lot like James.

Except for the tone of voice, except for those eyes.

But it was precisely these two differences that made him feel that this child was so strange.

"Are you really Harry?" Sirius hesitated and asked the question again.

This shouldn’t be the case…

How could James' child have this kind of personality?

Calm, mature and wise.

And he was only thirteen.

He was only one year old when the accident happened. How could he know everything so clearly?

Harry rolled his eyes, waved his hand, and continued: "I'll ask Hermione to inform Uncle Lupin, and he will bring..."

He looked back and paused, "No need to wait, I'm here now."

The wind and snow were everywhere.

Sirius looked and saw nothing, but he didn't know what to say, so he just waited quietly with Harry.

Harry waved his wand and a branch turned into a blanket, covering him and shielding him from the wind and snow.

"Oh, thank you," Sirius muttered, whispering his thanks.

He was now beginning to be convinced that this person was not "Snape", that person would not be so considerate.

Harry waved his hand.

After a while, Lupin, Hermione and Ron came over, with a huge bag floating behind them.

"This...what's going on?" Lupin looked at the hung Sirius in surprise. He had imagined the warm scene of godfather and godson recognizing each other all the way, but it didn't happen at all.

He even deliberately slowed down his pace to give them time to express their feelings.

"He won't listen. There's nothing I can do. I can only force him to listen." Harry answered concisely.

Sirius looked at Remus and buried his head in the blanket. "Harry, put me down, thank you. I won't run away. I really won't."

Harry waved his wand.

The man in the tree fell heavily into the snow.

"Sirius, long time no see." Lupin greeted him.

Sirius stared at the bag behind Lupin: "Is Peter in it?"

Lupin nodded and waved his wand, causing the bag to open, revealing a sleeping Peter.

"Let me kill him!" Sirius raised his wand and pointed it at him, his eyes fierce, "This despicable traitor..."

He hadn't been able to cast the spell yet.

A snowball hit him in the face.

The branches stretched out again and bound his hands.

"Calm down, my dear godfather." Harry said softly, "Revenge is also mine. Unless I die, you will be qualified to take over my place."

Sirius was terrified: "Don't say such unlucky words."

Harry looked at him with complicated eyes and said softly, "Now that you see Peter, you should feel relieved?"

"You won't suspect me of being Professor Snape after drinking Polyjuice Potion anymore, will you?"

Lupin's eyes widened.

Hermione also looked incredulous.

"The way you curse is so much like that slug." Sirius turned his head away, looking unconfident.

Harry shook his head: "I want to ask you a question."

Sirius raised his head and looked him in the eye: "I will tell you anything you ask, Harry. I won't hide anything from you."

"Why have you been refusing to tell anyone the truth for thirteen years?" Harry inquired.

Sirius sighed and lowered his head: "Harry, I'm sorry for you, sorry for James, sorry for Lily."

"Their deaths were caused by me..."

Harry interrupted him: "Your name."

Sirius was stunned.

Harry waved his hand and asked again: "Your name."

"Sirius Black," he answered blankly.

Harry nodded. "I thought you were so stupid that you forgot your name and thought your name was Peter Pettigrew, or Tom Riddle."

"Who is Tom Riddle?" Sirius asked curiously.

"Voldemort," Harry answered.

Except for Ron, they all couldn't help but shiver even though Hermione was trying to control herself.

"It was Voldemort who killed my parents, and it was Peter who betrayed my parents." Harry poked his chest with his wand, "Don't take the blame for my parents' death on yourself."

"Perhaps Voldemort and Peter will feel that you are stealing their credit."

Sirius couldn't hold back his tears, "But, but I suggested that James change the secret keeper to Peter. If it wasn't for my suggestion and my insistence, this would never have happened."

"Really?" Harry shook his head and looked at Peter floating in the air. "But if Peter could insist on not betraying his friends, wouldn't this happen?"

“Don’t dismiss the only idea you ever came up with.”

Peter's eyelids twitched.

"Don't pretend to be asleep, Peter, I know you're awake." Harry waved his wand and a snowball hit the mouse in the face.

Peter woke up shivering and was just about to speak.

Harry cast a spell: "Now is the time for our family to reunite. Unlucky people should stay silent."

Peter opened his mouth, but no word came out.

"Family reunion".

These few words touched the most vulnerable part of Sirius' heart, making him cry even louder. After a while, he sobbed and said, "Harry, can you let go of my hand?"

"At least let me wipe my tears. They are frozen."

Harry waved his wand.

Sirius brushed the ice off his face.

"Have you ever thought that if you had told Dumbledore about this earlier, Peter would have died thirteen years ago." Harry walked up to Sirius and looked up at him.

Sirius was stunned.

That makes sense, but...what was my thought thirteen years ago?

Harry covered his face helplessly: "Very good, my dear godfather, really, I really didn't expect that I am beginning to agree with what Professor Snape said."

"No, Harry how could you, that evil guy..." Sirius roared angrily.

But no one paid any attention to him.

Lupin patted Harry on the shoulder and comforted him: "Sirius is just a special case. Think about Hermione and Ron. They are both very smart and intelligent Gryffindors."

Sirius gritted his teeth and let out a low growl like a barking dog.

There are clearly six Gryffindors here - oh, that scum Peter doesn't count, there are clearly five Gryffindors, why is he excluded?

"What are you going to do next?" Lupin asked the key question.

Sirius responded immediately, in a fierce tone: "Just kill Peter!"

"Such a despicable thing should be torn into pieces!"

Lupin changed his words and asked again: "I mean, how do you want to clear Sirius' name?"

"It's simple, just a memory." Harry said softly, walked to Peter, put his wand to his temple, and chanted a spell.

He slowly pulled out the silver thread.

"What is this?" Ron swallowed.

"Memory Charm, Harry, how do you know this?" Sirius tilted his head back, a little surprised.

Harry replied calmly: "Professor Snape taught me."

Sirius was stunned.

He suddenly felt very unhappy. He turned his head, rolled out a snowball, and threw it at Crookshanks, who was staring at the memory thread and ready to make a move.

It reacted quickly, shrinking its body and almost being hit. The sudden attack made it scream in anger, and it pounced on Sirius, slapping him hard in the face, leaving a claw mark.

It knew that this person was not a good dog.

Putting the memory into the bottle, Harry threw it into the Sorting Hat: "That's enough."

"Is this okay?" Lupin asked a little worriedly.

Harry chuckled, smiling widely. "Of course. A memory, a corpse of a 'hero' who should have been blown to pieces but survived for thirteen years, and a stupid godfather who could be fed truth serum at any time."

Sirius was stunned: "Harry, you can remove that word."

"And idiots who can be fed Veritaserum at any time," Harry agreed.

Sirius clenched his fists and lowered his head: "Then it's still the stupid godfather."

Lupin said softly: "You really look like your mother when you smile."

"Godfather, give me the wand." Harry held out his hand to him.

Sirius didn't hesitate.

Harry untied all the restraints on Peter.

As soon as he landed, he threw himself at Harry's feet: "Harry, I am your father's best friend. You can't kill me. Even if you want to clear Sirius's name, you should hand me over to the Ministry of Magic."

Harry handed the wand to Peter and said calmly, "It's been thirteen years. Do you still remember how to cast spells?"
