Professor Lupin told Harry some stories about his school days. They were all trivial matters, but Harry was fascinated by what he heard.

It was not until Professor Lupin mentioned the graduation of the seventh grade that he turned his attention to Sirius Black, because after graduation he had been helping Dumbledore contact other werewolves and had no idea what was happening here.

By the time he got the news, James and Lily were both dead, and Voldemort had fallen. It seemed as if the originally huge and terrifying Death Eater army collapsed overnight.

Including the werewolves he had been in contact with, after losing a large number of members, they hid back in the dark corners and could never be found again.

By the time he finished speaking, Blake had already fallen from mid-air.

"It all started with a prophecy..."

He sat on a tattered stool, and under everyone's gaze, he slowly told the truth of that year.

Professor Trelawney made a prophecy of the savior, saying that the child who could defeat Voldemort had been born. There were two children born that year, and Dumbledore finally chose Harry.

But somehow, the Death Eaters also got the news.

"It must have been Peter who told us the secret..." Black gritted his teeth and said, "Dumbledore told James not to let anyone else know about this, but he still told us..."

"And then what..." Harry asked eagerly.

"James and Lily took you with them, hiding from the Death Eaters." Black fell into memories and murmured, "Then they decided to adopt Dumbledore's suggestion and use an ancient magic to protect you as you grew up.

The curse of loyalty.

It is a kind of magical power that can hide secrets in a person's heart, such as the address of a house.

As long as the Secret Keeper doesn't reveal James and Lily's location, Voldemort won't be able to see them even if he puts his nose to the window."

Hearing this, Harry roughly understood what Black meant.

"So, Peter is the secret keeper, right?"

"It's all my fault!"

Black suddenly hit his head and said hoarsely, "The Secret Keeper was originally mine, but I persuaded Lily and James to use Peter instead at the last minute... I thought it was a good plan... a substitution plan. Voldemort would definitely come to me, and he would never have thought that they would use a weak and incompetent person like Peter...

It was me who killed Lily and James..."

Blake became more and more excited as he spoke, but every time he gritted his teeth in hatred, he would think of Peter's current situation and then burst into hysterical laughter again.

But even in the laughter, Harry couldn't hear a single bit of happiness.

After Blake calmed down again, he told others what happened afterwards in a disjointed manner when asked by others.

Including how he saw Scabbers' photo in the newspaper and recognized it as Peter, and how he used the Animagus to escape from Azkaban and come to Hogwarts.

"So that dog is you!" Harry said, pointing at him.

"Yes, it was me." Black grinned. "I wanted to see you, so I went to Privet Drive. I'm sorry, but I seem to have scared you at the time."

Harry didn't know what to say... Black had scared him more than once, and he had been living in fear for the past few months because of the big black dog.

"Sorry, Sirius." Lupin walked over and hugged him.

"Long time no see Remus." Black hugged him backhand, "You really should beat me up."

"I thought so too." Lupin nodded and punched Black in the face without warning. "You should have told me this earlier."

Blake flew backwards and fell to the ground, but he was smiling again.

Professor Lupin walked over, grabbed his hand, pulled him up, and the two hugged each other again.

"Forgive me, Remus..." Black said.

"Not at all, Padfoot, old fellow," said Lupin. "Then you'll forgive me for ever thinking you were a spy, won't you?"

"Of course." A smile flashed across Blake's haggard face.

"terribly sorry……"

Although he didn't want to disturb their brotherly love, it was already very late and Kyle was not going to stay in such a place all night.

He walked over and handed Blake the cage containing Scabbers.

"Of course, that's the way it should be."

Ron, who had a bitter face, suddenly brightened up his eyes when he heard this.

You should have said it earlier...

If I had known that Banban could be exchanged for an owl, would I have bothered with this?

Blake took the cage with a ferocious expression, as if he was going to eat Banban. Then he looked at Kyle and was about to thank him when he suddenly remembered something...

"I think I've seen you before." Black said, "Remember, in Hogsmeade, you gave me a bag of jerky. It was the most delicious thing I've eaten in the past decade."

"Oh, that time." Kyle pretended to be surprised. "You deserved it. Your performance of jumping through the fire ring was amazing..."

There was silence again.

"Going through a ring of fire?" Professor Lupin looked at Black with a very strange expression. "You can do this?"

"Uh..." Blake's eyes were evasive for a moment, but he quickly returned to normal and looked back with all his strength.

Anyway, he was just a dog at that time. What was wrong with going through the fire ring? Besides, it was just to fill his stomach, so it was not shameful.

"Ha..." Professor Lupin chuckled, which was unusually clear in the small room.

It was like a fuse had been lit.

Ron and Hermione turned their heads away and shrugged their shoulders.

"puff……"

Harry, who was originally immersed in the truth, couldn't help but laugh.

Perhaps he felt that this was not a good idea, so he quickly covered his mouth with his hand and changed the subject: "How are you going to deal with Madara...Peter?"

"Of course I'll kill him!" Blake looked at the unconscious rat in the cage, "But it's not bad now, let it be a rat forever!"

"Is he really unable to change back?" Harry asked softly, "I mean... this kind of person is not worth you becoming a real murderer.

And Peter is the real traitor. If anyone should go to Azkaban, it’s him, not you…”

Blake's eyes were red and he was breathing heavily.

If possible, he certainly wanted to get rid of those Dementors forever. Only in this way could he take care of Harry openly.

But the problem is that Blake doesn't know if Peter can change back...

In unison, everyone looked at Kyle.

"Actually, yes." Kyle said, "After wizards discovered the Animagus that couldn't transform back into human form, they studied related potions.

"Remember those people who were petrified by the basilisk in second grade?"

Everyone nodded. They naturally remembered clearly the time when Hogwarts was almost closed.

"The resurrection potion that finally removed their petrified state was invented at that time. This was also the only way to restore him."

"but……"

He looked at the surprised crowd and continued, "Before making a decision, I think you'd better go see Professor Dumbledore.

After all, everyone now thinks you are a traitor and Peter is a hero. No one will believe a traitor... You don't even have a chance to defend yourself, because the Dementors won't listen to your explanation.

Unless you can convince Professor Dumbledore to help you."

"You're right." Blake calmed down, "I'll go tomorrow."

"No, we can go now," Kyle said. "He has a shallow sleep, so just knock on the door a few more times."
