According to the map, Harry's location is in the fifth floor bathroom.

William and Hermione soon found him.

Strangely, Harry was the only one, and Ron was not Ron... that is, Peter!

"What's wrong, you two?"

Harry was a little nervous and looked suspicious.

"You won't peep at the girl's bathroom, are you?" William asked with his eyes narrowed.

"No...no..." Harry stuttered, as if he had confirmed the crime even more.

"Where is Ron, Harry?" Hermione asked.

"He, my stomach is uncomfortable, I'm entering the bathroom, I'm waiting for him at the door," Harry said quickly.

William frowned.

Harry said impatiently: "What happened? Did Peter have something wrong?"

"Ron is Peter, he pretended to be with compound decoctions." Hermione replied.

"How is this...is possible..." Harry trembled, and he swallowed, "Impossible...you two must have made a mistake..."

His face was pale and hardly bloody. He seemed to be scared by the news that Ron was Peter.

"Where is Ron really..."

William glanced at Harry, without saying a word, and kicked open the door of the man's bathroom.

He carried a magic wand and searched each compartment, without Ron, and without Peter.

Walking out, William shook his head at Hermione.

Hermione glanced at the female bathroom. William understood and pushed open the wooden door. Hermione walked in with her wand.

"Hey, that's the girl's bathroom, William." Harry couldn't help but remind.

William ignored him and continued to search each compartment carefully.

"It seems that he has turned into a mouse and ran away from the toilet." Hermione sighed disappointed.

The mouse has a strong ability to drill the toilet and can swim out of the sewer and along the toilet.

Peter really fought to escape!

William had already anticipated this result and there was not much fluctuation.

The only strange thing is that Peter will never leave with an empty hand if he wants to leave Hogwarts.

Just take Harry away secretly.

Are you afraid of being discovered?

"What are you doing?" Professor Lupin's voice suddenly came from a distance.

Standing at the entrance of the stairs, looking at William and Hermione coming out of the girl's bathroom, he showed a strange expression.

"Professor, why are you here?" Hermione asked nervously immediately.

"Is something wrong with Professor McGonagall's office?"

"No...I don't think I'm very relieved. I want to send you back to the common room." Lupin said gently.

"There are Sirius and Professor Snape in the office. They will look at Peter and nothing will happen."

As soon as the words were finished, a violent explosion came from the second floor.

Lupin: “…”

William and Hermione looked at each other.

Something happened!

"Professor Lupin, you need to send Harry back to the common room now, and you will be guarding him tonight." William said immediately.

"Peter used compound decoction to turn Ron, and he probably had run away, but he could not rule out the possibility of returning to capture Harry.

I need you to protect him, do you understand?"

Lupin was stunned for a moment, looking at the serious William. At this moment, he seemed to see Dumbledore giving orders.

For some reason, Lupin couldn't afford any objection, even if he was... a professor and an adult wizard

Lupin looked at William, who was only fifteen years old, nodded obediently, and said seriously: "Yes, I understand."

William stopped talking nonsense and turned around and walked quickly towards the second floor. Hermione followed closely behind him.

"Let's go, Harry." Lupin took out his wand.

Harry's face was pale and his hands were shaking.

After William completely left, he suddenly felt difficult:

"Professor, I probably...know... where Ron... Peter... is hiding!"

...

...

When William and Hermione rushed to Professor McGonagall's office, the room was full of people again.

Sirius had fallen to the ground, his nose was bleeding. He himself was knocked unconscious.

The two Aurors held Snape, but the professor was particularly unhappy and pulled out his legs and kicked Sirius a few times.

"Severus, what are you doing?" Dumbledore's blue pupils, half-moon glasses were cast, and he looked at Snape sternly.

The expression on Snape's face was mixed with anger and disgust.

He shouted:

"It was him who begged me to hit him... so arrogant... I have never heard of such a mean request... I can't beat you to death... Haha~ so!"

Snape spitted, but because he was too excited, he spitted on his shoes.

He was furious and rushed over again, trying to kick Sirius' crotch a few times.

Hiss ~ So cruel!

What a grudge this is?

And Sirius, are you too weak... You were actually given a second by Professor Snape?

That's it,

That's it?

Well, it is normal to not be able to beat it. Professor Snape is a fierce man who has been applying for a position in black magic defense and wants to resist Voldemort's curse in his body.

And what about Sirius?

He was locked up in Azkaban in his early twenties. The gap in magic over the years has become like a gap.

"Severus!" Dumbledore's tone was aggravated.

"Hmph!" Snape glared at Dumbledore, not using his son and grandson's feet.

Dumbledore also regretted it a little that he shouldn't have put the two together.

Where is Lupin? He can’t afford to fight!

"Professor Dumbledore, I need to talk to you alone... about Peter and Ron." William suddenly interrupted several people.

Ron was still holding Peter's face and was tied to a chair. Therefore, the effect of the compound decoction has not yet passed.

But Peter was gone again and he was about to send Sirius away first.

"Well, go, go to my office," Dumbledore said.

Hermione suddenly grabbed William's hand and she showed a look of horror.

William followed her gaze and Ron, who was tied to a chair, suddenly began to deform.

His hair is turning red, his nose is slowly getting longer, his skin is smooth, and he has a lot of freckles.

"Weasley!" Snape stood there.

"Merlin." Professor McGonagall opened his mouth wide and made a harsh sound.

Minister Fuji looked at the scene in front of him in shock, and he was completely shocked.

"What's going on..."

He slapped Delis next to him, as if he was sure whether he was sleeping.

"I must be sleeping...it must be like this. When I wake up, I will see Umbridge's face." Fudge said silently.

Dumbledore glanced at William, who was helpless in spreading his hands, saying that this was the case.

The principal walked over seriously.

"Compound Decoction... There is no doubt that Mr. Weasley was poured into the Compound Decoction before he became Peter.
