Professor McGonagall

William's gaze was drawn to the ring, and his heart pounded.

The design of this ring is very similar to the Eagle-shaped bronze knocker in the Ravenclaw Common Room.

If you magnify the ring tenfold, it becomes that door knocker!

William's thoughts began to drift.

If this thing is a lounge door knocker, then how did it end up in Fluffy ' mouth?

The only person who came here today was Professor Tywin!

William walked over to Fluffy, stepped on the pile of trash, and smacked its mouth.

"Good boy, Fluffy, I was rude just now. Here, have some dried fish. Open your mouth, come on, do as I say, ah--"

Fluffy opened his mouth wide as a foul, fishy smell wafted over, and William quickly held his breath, otherwise he would probably suffocate.

William shoved his head inside, examining Fluffy's teeth like a veterinarian.

There was a lot of blood on the sharp teeth, probably Professor Tywin's, and a wand was stuck between them.

--Ebony magic wand.

This is Professor Tywin's wand.

In other words, the door knocker was indeed brought by Professor Tywin.

William pulled out his wand and stood still, his thoughts churning in that instant.

He understood everything.

The one who stole the door knocker was Professor Tywin, who was also the one who left the writing and called himself Death Eaters!

Why did he steal the door knocker?

Is this really Ravenclaw's Bronze Ring?

William looked at the ring and, as if possessed, put it on the index finger of his right hand.

He closed his eyes and waited for a while, but nothing happened!

Where's the promised Yao Lao? If not, then surely Ravenclaw's soul must be residing there?

Does it require a secret code, like Marauder's Map?

William cleared his throat and, as if chanting, said, "Ring that conceals the power of knowledge! Show me your true power! Stark, who made the pact with you, commands you: release the seal!"

Nothing changed; the only sound was Fluffy wolfing down his snacks.

William was somewhat disappointed.

He squinted and thought for a moment. Could it be that he was wearing it incorrectly?

He remembered that Ravenclaw had a daughter, so he must be married, and the ring shouldn't be on his index finger, it should be on his ring finger!

William held the ring in his left hand, trying to take it off.

But a strange thing happened: the ring that had been so easily put on suddenly wouldn't come off.

Looking at the ring, William sighed. He thought it best to go find Dumbledore first.

Dumbledore knowledgeable and experienced; given Anne's influence, he will surely help him.

Similarly, William discovered Professor Tywin's secret and, feeling there was still a chance to salvage the situation, told Dumbledore about it.

If it is verified that Professor Tywin is indeed Death Eaters, then Fluffy not only did nothing wrong, but also deserves credit.

William might also receive a school award for outstanding contributions.

In any case, you have to tell Dumbledore, given his abilities, he wouldn't stand by and watch Hagrid die.

What else could it be? Did William, a mere wizard, really intend to single-handedly break Hagrid out of Azkaban, or believe he could solve the whole problem on his own?

Then he's become too arrogant and too Gryffindor!

After leaving the Room of Requirement, William returned to the Defense Against the Dark Arts Office, but it was empty; even Tywin's body was gone.

It seems everyone has left.

William went to several offices but didn't find the professor. He came to the lobby on the first floor and found McGonagall standing alone at the door.

The wind blew her long robe, and she remained silent, tears streaming down her face.

William was truly discovering for the first time that Professor McGonagall was such a sensitive person.

"Professor McGonagall, here you go." William approached and handed her a piece of paper.

After expressing her gratitude, Professor McGonagall wiped her face and scolded, "William, you shouldn't be here. Go back to the Ravenclaw Common Room."

William nodded, but didn't leave. Instead, he asked, "Where is Professor Dumbledore in his office?"

"No, he went to the Ministry of Magic with Minister Fudge."

"Ministry of Magic... Why did the headmaster go to the Ministry of Magic?"

William panicked. Had Hagrid already been captured?

"Professor Snape has been taken away, Dumbledore went with him," Professor McGonagall replied.

Upon hearing that it wasn't Hagrid who had been arrested, William breathed a sigh of relief, but the next second, he suddenly looked up.

"What?! Professor Snape has been arrested again?!"

It's no wonder he was so surprised; Professor Snape had indeed been having a run of bad luck lately, and even seemed to be a scapegoat.

He's been to the palace twice in one year; I doubt anyone else does that.

McGonagall looked at William, her tone growing increasingly stern. "William, these are not things you should be asking. Now, get back to the Ravenclaw Common Room."

William remained motionless. Since Dumbledore was not there, the only professor he could find was McGonagall.

He trusted Professor McGonagall, just as he trusted Dumbledore.

After a moment's thought, just as Professor McGonagall was about to erupt in anger, William decisively said, "Professor, I have something to discuss with Professor Dumbledore, but he's not here right now. I can only tell you this now; it concerns the murderer of Professor Tywin."

As he spoke, William took out the ebony wand and handed it over.

Professor McGonagall's pupils contracted sharply. She stared at William and said seriously, "We've been looking for Professor Tywin's wand for a long time. How did it end up with you?"

William quickly recounted what he knew.

Of course, he cleverly covered up all the things he had done that violated school rules, as if he had suddenly discovered Fluffy or suddenly realized that Tywin had a problem.

Professor McGonagall, after hearing this, naturally couldn't believe it so quickly.

William then took her to the Room of Requirement to show her Fluffy, to prove what he had said.

Professor McGonagall led William into her office, where she sat down, arms crossed, deep in thought.

Professor McGonagall frowned seriously; there were many things that couldn't be explained at the moment.

William's words were indeed logically consistent, which left her no room for carelessness.

William sat in the chair, listlessly looking around the room.

This was his first time entering Professor McGonagall's office, and what greeted his eyes was a vast collection of books.

Professor McGonagall once said that the Sorting Hat considered whether to sort her into Ravenclaw, and it seems that what she said was true.
