A friendly day at Hogwarts

Seeing that Harry and the trio were all curious, Hagrid did not refuse and told them about the past.

"Speaking of which, when I heard that Sirius betrayed James and Dumbledore, I was absolutely furious. You know, he is the person James trusts most in the world!"

Harry asked in confusion: "You said he is the person my father trusts most? But why has no one mentioned this for so long?"

Due to the changes in the plot, Harry at this time neither received Mr. Weasley's instructions nor heard the chat between Fudge and the professors at the Three Broomsticks Tavern. He also knew nothing about what happened that year.

"This..." Hagrid looked slightly embarrassed, "Everyone behind him thinks he is a betrayer, so they are unwilling to mention him in front of you..."

He organized his language and continued: "When they were still studying at Hogwarts, James and Sirius were inseparable every day, just like brothers like the Weasley twins."

Harry was slightly surprised. It had been nearly two years since he came to Hogwarts. Apart from the previous images in the Mirror of Erised, he had heard almost no news about his parents.

"That's right!" Hagrid slapped his forehead, "When your parents got married, they specially asked him to be the best man. Do you still remember the photo album I gave you before? When you were in the school hospital last year, the one with leather cover Book?"

"Of course." Harry nodded, "I keep it in the drawer of my bedside table!"

"If I remember correctly, there should be photos from the wedding in that album, and there should be photos of Sirius and your parents in it." Hagrid said, "After you were born, James even asked him to be your godfather. !”

"My godfather?" Harry looked very surprised at the fact that he had a godfather for nothing.

"That's right." Hagrid nodded, "That's why I was so angry when I mistakenly thought that Sirius had betrayed James."

Harry was obviously interested in this and couldn't wait to say: "Tell me more about them, Hagrid! About my parents, godfather, and Pettigrew. What happened back then, and what happened to Pettigrew?" How did you betray my parents?"

Hagrid nodded and started talking.

"Your parents are heroes who fought against You-Know-Who. Harry, since they graduated, they have been working under the leadership of Dumbledore to prevent You-Know-Who from destroying the world."

Harry had already heard some of these background stories, and he didn't show any surprise.

"They are very brave. It is very dangerous to go against a mysterious person. Even Dumbledore cannot completely guarantee their safety."

Having said this, Hagrid looked slightly disappointed, as if he was remembering those dark days.

"Later, Dumbledore got the news that the mysterious man seemed to be planning to hunt down James and Lily. He immediately relayed the news to them and suggested that they hide. He mentioned a very effective spell called... ..”

He looked confused mid-sentence, apparently forgetting the name of the curse.

"You mean... the Fidelity Charm?" Miss Hermione, a know-it-all, knew everything and immediately guessed what he wanted to say.

"Yes, yes, that's it!" Hagrid slapped his thigh and gave Hermione a thumbs up.

"The Fidelity Charm? What is that?" Ron spoke at the right moment, asking the question that Harry was thinking about.

"That is an extremely complex spell." Hermione explained, "It can completely hide a secret in the heart of a specific person. This chosen person is also called the secret keeper. Unless the secret keeper takes the initiative to leak it, otherwise No one else will ever know the secret."

Seeing that Harry and Ron still looked confused and didn't understand, Glenn added: "For example, if Harry's father used this spell on his address, let Dumbledore do it. Secret Keeper. Then unless Dumbledore tells Voldemort this secret himself, he will never find your parents in his lifetime, even if he smashes his nose on the wall of your house."

After hearing what he said, Harry and Ron finally understood the magic of the Loyalty Charm.

"But according to what you said, how did Voldemort find us in the end?" Harry tilted his head and thought for a moment before asking again.

Glenn was at a loss for words and didn't know how to answer this question.

If James and Sirius hadn't honestly asked Dumbledore to be the secret keeper, and hadn't engaged in the cunning operation of changing people back and forth, Voldemort would not have been able to find their hiding place so easily.

"This is why we have regarded Sirius as a traitor for so many years..." Hagrid said, "Dumbledore had already noticed that someone around them had secretly contacted the mysterious person, so he specially proposed He wanted to personally serve as their secret keeper, but James did not agree and insisted on using Sirius."

"What happened next?" Harry asked impatiently.

Hagrid sighed and said: "Dumbledore's judgment was very accurate. Less than a week after the spell was cast, they were killed. No one knows what happened that night, but you were the only one who survived. Mysterious People have completely disappeared.”

"So, my godfather betrayed my father?" Harry looked confused, "But didn't you just say..."

"That's the problem," Hagrid said. "We've always thought so. It wasn't until a few days ago that Peter Pettigrew was arrested, and the truth came to light."

"But what does Pettigrew have to do with my father and the others?" Harry continued to ask.

"James, Sirius and Peter Pettigrew were classmates at Hogwarts back then. Together with a young man named Remus Lupin, they organized a small group specializing in pranks. I have already remembered the name. Incredible." Hagrid explained, "They are both Gryffindor students and have a very good relationship with each other. Of course, the closest ones are James and Sirius. They are the core of the group and the core members of Hogwart. He is the best student of Tsz, and of course, the guy who gives the professors and Filch the most headaches. As for Pettigrew, he is always like a follower, following behind the three of them, and he is inconspicuous at all."

Harry frowned, vaguely thinking of a possibility: "According to your statement, could it be..."

"If I'm not wrong," Hagrid said, "when they cast the spell, because the relationship between Sirius and James was too obvious, they temporarily changed the secret keeper to Pettigrew. Who would have thought that, The most inconspicuous little star actually betrayed them."
