William's Animagus form is an Arctic wolf. He paced around the house, jumped gently to the coffee table, and then jumped down. His cool and heroic posture shocked Black.

"Congratulations, Scorpion" Black said "You learned Animagus"

William changed back to human form and stretched out his hand

"Thank you all, Professor Black," said William, who held William's hand hard.

"Since you've learned Animagus, I think we should be separated," said Black.

"Indeed, our partnership is over," William said as if nothing had happened.

"But our friendship has just begun," William continued. When talking about friendship, Black shook nervously again.

"Sirius, your life will be better," William said

"Thank you, I have something to do that I have to do," Sirius said

"I think this matter can be waited until next year," William said

"No, I've been waiting for 12 years, in Azkaban!" Sirius was a little excited. He has recovered a lot now, both physically and psychologically, but this matter is more important in his heart than his life.

"I only think of one person, Petr," William sat down.

"How did you know?" Black looked at William in surprise. William induced Black to tell the facts himself. After all, although William knew some things, he could never say them.

"Twelve years ago, you were arrested because of Peter, who had only one finger left, and the rest of his body disappeared." William said

"That coward cut off one of his fingers and ran away!" Black was excited when he mentioned Peter again when he mentioned that he was excited.

"So you escaped from Azkaban because you found Peter?" William asked "temporarily".

"Scorpion, you are the smartest wizard I've ever seen you." William smiled and Black continued:

"There is a mouse in the Weasleys's house. I saw the mouse in the Prophet Daily. It was Peter's Animagus, and the mouse had a finger missing!" Black said hatefully.

"What are you going to do with Petr" William took a sip of chocolate tea

"For this beast who betrays his friend, he must let him disappear in this world." Black seemed to see Peter's death, with a ferocious expression.

"I think Harry should be the one who decides all this," William put down his teacup and said to Sirius.

"After all, the Porters are his parents"

Speaking of the Porters, Sirius had sadness on his face, and he stood up and paced around the house.

"You're right, Harry has the right to know all this and to decide how Peter should be dealt with," Black sighed.

"So, we have to find a way to let Harry know the facts, and then capture Peter, the Petrite, and give it to the Ministry of Magic, to lift the accusation against you, and that will make you free." William paused.

"We? I can't get you in," Sirius said

"First point, you and Harry are both my friends, and second point, Hogwarts will definitely have dementors guarding the next semester." William brought the dementor out, and Black was very afraid of the dementors.

Sure enough, when Black shivered when he heard the dementor, William continued to say

"If you go to Hogwarts rashly, not only will Dumbledore not believe you, but Dementors will not let you go. Then you will be very dangerous and will undoubtedly be lifeless. And if you can endure it for a while, and wait until Harry discovers what happened twelve years ago, and when Dumbledore's cooperative relationship with the Ministry of Magic has cracks, Dumbledore is unwilling to cooperate with the Ministry of Magic again, and wait until the Little Dwarf is caught and will not escape. At that time, you will appear again in Hogwarts and explain it to Harry in person. Isn't this better?" William said.

William did not want Black to go to Hogwarts rashly, so that he would be executed if he didn't even have the chance to see Harry, so Harry could not know how much Black had paid for him. And William could not tell Harry this fact, so Harry could only discover that in front of Harry's family affairs, William was not the one who should tell him the truth, but Black was the one. So Black needed to be patient.

"What did I do during this period? I can't stay in this place all the time." Black was very depressed. William was right. Impulsiveness could only backfire. Happy that it was Peter.

"My advice is that you go to the Muggle world abroad for a while, and everyone thinks you will go to Hogwarts to hurt Harry. There is no wanted business about you in the Muggle world abroad. You should thank you for not being an international wanted criminal." William continued to see Black hesitant and said

"I will pretend you to be at Hogwarts around the school, which will make Dumbledore and the Ministry of Magic nervous. The more they are, the more conflicts they are, and the more complicated the relationship will be. When Harry knows about you, I will grab Ron's pet, Peter, and then bring you into the school. In this way, you will have the opportunity to make it clear to Harry in person. Of course, the decision afterwards will depend on Harry. Peter is alive, even if he can see his body, I believe that the Ministry of Magic will give you freedom."

"Scorpion, I don't understand why you did so much for me" Black said

"Because you are a trustworthy friend," William said with a smile, "I believe you will understand my choice in the future."

"And, in the future, you can call me William." As William turned back to his original appearance, chestnut hair and dark blue eyes.

"You" Black was surprised to see the changes in Scorpion and couldn't speak.

"Friend, you are the only person who knows my identity as a scorpion. I hope you can keep it a secret for me," said William. Black wanted to speak but stopped. William had gained his trust.

William's approach attracted Black and allowed him to enter his own camp. As for Scorpion's identity, William would definitely be there when Black and Harry talked about the facts, and that identity would definitely be exposed. It would be better to say it now to win trust.

Then, William took Black's phantom and moved to a countryside in Germany. William left Black enough money for him to spend a year. Knowing Black's address, William said that he would often post and write letters to Black, asking Black to endure. Black sometimes felt that he was a failure. William was really a little brother with a lot of big ideas.
