He unconsciously wrote a note about the password to the Gryffindor lounge, and under William's arrangement, he was released at the critical moment so that Sirius Black could get the Gryffindor password, and broke in and forced him to
Peter Pettigrew, also known as Scabbers, escapes from the Gryffindor common room...
As for why not let Crookshanks take Sirius to find Peter?
That's because William doesn't trust Sirius Black, mainly because he doesn't want Sirius to know that William and Hermione's pets can talk at this time.
You know, Sirius is a loyal follower of Dumbledore. He completely trusts Dumbledore and the Order of the Phoenix in everything. He even donated his family's ancestral home to the Order of the Phoenix as a base.
Therefore, once Sirius knows about this matter, he will definitely leak it to Dumbledore in the future.
Dumbledore's paranoia may also deepen his suspicion and vigilance towards William and William.
Moreover, once Crookshanks speaks, Sirius Black may think that Crookshanks is an Animagus, causing unwarranted misunderstandings and troubles, which is not conducive to William's plan.
Sure enough, one day when the full moon was about to come, the big dog transformed by Sirius Black came to the door of the Gryffindor common room and said the password according to the note.
When Sirius Black came to Harry's bedroom, Peter Pettigrew started to run away in horror.
He used his small mouse body to hide from Sirius in the corner of the bedroom, and ran out of Hogwarts Castle in a panic.
At this time, William, Hermione and Neville, who had already brought the Marauder's Map, happened to see a mouse and a big dog heading towards the Whomping Willow on the edge of the Forbidden Forest.
When William saw this, he immediately said to Neville:
"Neville, go find Harry and Ron. They are having dinner in the Great Hall right now and they said we saw a big black dog chasing Scabbers to the Whomping Willow!"
Upon hearing this, Neville immediately ran to the castle's auditorium.
In the Great Hall of Hogwarts, Neville panted and ran to Harry's side and said:
"Harry, Ron, we just saw a big black dog chasing Scabbers to the Whomping Willow!"
Ron shouted immediately after hearing this:
"What? Scabbers is being chased by a big black dog? How could this happen? Where did the big black dog come from in Hogwarts? Was it raised by Hagrid?"
Then the three of them ran towards the outside of the castle.
Ron's scream attracted everyone's attention. Malfoy even laughed at the Slytherin table next to him:
"Weasley's mouse with a broken toe was actually chased by a black dog, hahaha. I really hope your pet Scabbers didn't die in that black dog's mouth..."
The speaker has no intention, the listener has intention.
Lu Ping, who was sitting at the professor's desk, was shocked when he heard this. He put down the potion he was about to drink and ran towards the outside of the castle.
Snape had been wary of Professor Lupin, and when he saw him suddenly running out without even drinking the wolfsbane potion he had prepared, and because he seemed to be chasing Harry, his expression suddenly changed.
, picked up the potion on the table and chased after him.
When Harry and Ron caught up with William and joined them, they happened to see the big black dog carrying Scabbers in its mouth and burrowing into the tree hole of the Whomping Willow.
Ron suddenly shouted in horror:
"Banban! My Banban!"
With that said, he directly activated the "Phantom Scale", preparing to resist the attack of the Whomping Willow and go to the tree hole to find his pet.
Harry caught Ron in time and whispered:
"Ron, calm down!"
Ron angrily threw Harry's hand away and shouted:
"Why? That's my friend who grew up with me!"
Harry was a little helpless when he heard this, and finally scratched his head and said:
"Ron, have you ever seen a mouse that lived for thirteen years? Normal mice can't live that long at all!"
Ron looked at Harry and calmed down, while William took out the Marauder's Map in his hand and said:
"Ron, look, look, who is in the Whomping Willow!"
Ron picked up the Marauder's Map in confusion and saw two names flashing in the secret passage marked with the Whomping Willow: Sirius Black and Peter Pettigrew.
"How is that possible? Sirius is inside, Harry, let's get out of here!"
Ron screamed in horror, and the hand holding the Marauder's Map was trembling slightly.
Seeing his good friend so worried about his safety, Harry felt warm in his heart.
William continued to remind:
"Ron, although it may be difficult for you to accept, I still have to tell you that your pet Scabbers is an Animagus, and Peter Pettigrew inside is Scabbers!"
Ron was shocked when he heard this. He didn't want to believe it, and his expression kept changing.
Harry opened his mouth and said:
"We confirmed after getting the Marauder's Map that besides us, there was Peter Pettigrew in the bedroom at that time. His name was just next to yours."
When Ron heard this, he immediately thought that he always liked to sleep with Banban on his bed, but when he thought that he might be holding a middle-aged man, Ron felt nauseated and confused.
Although this is a rotten country, my sexual orientation is very normal and I like girls. Now I find that I always sleep with a male wizard in my arms, and I can't accept it.
At this moment, Professor Lupine, who was slightly weaker from behind, also chased after him and heard about Sirius Black and Peter Pettigrew.
He said nervously:
"Harry, Sirius is in there too? You come to the castle quickly, and I'll catch Sirius!"
As he said this, he wanted to ask Harry to go back first.
Harry said:
"Professor Lupine, let's go in together. I also want to see my enemy!"
Looking at Harry's firm eyes, Professor Lupine nodded slowly.
Then several people got into the secret passage and walked inside.
On the way, Professor Lupine also introduced this place to Harry and others:
"This was originally our and your father's secret base. Outside is the Shrieking Shed in Hogsmeade..."
Finally, at the last corner, I saw a middle-aged man with disheveled hair holding a wand to the head of a male wizard who was kneeling on the ground with a broken finger.
Harry and others quickly recognized the two people inside. The one holding the wand was his godfather Sirius Black, and the one kneeling on the ground should be his real enemy Peter Pettigrew.
Harry couldn't help but tighten his hands. The thought of whether he should take this opportunity to directly kill Peter Pettigrew to avenge his parents kept echoing in Harry's mind.
In the end, Harry released his right hand that was holding the wand tightly. Harry was not prepared at all for killing people. After all, he was just a thirteen-year-old boy and could not kill decisively.
Professor Lupine came in and raised his wand to warn Sirius:
"Don't move! I didn't expect it to be you, Sirius, why did you betray James!"
Sirius was also very shocked by the arrival of Harry and others, but he couldn't express his pain. It seemed that no matter how he explained, it was difficult to gain their trust.
The chasing little star seemed to have found hope of survival and said:
"Remus, save me quickly..."
