The look on Justin Finchrie's face was very, very painful.

He clutched his head as hard as he could, as if it was about to explode.

"If you can't think of it, don't think about it anymore. Matthew calmly reassured.

At the same time, he bent down and picked up all the gadgets that Justin had dropped on the ground, and then gave them back to him.

"Thank you!" Justin's face softened slightly, and he took them back into his arms.

Then, with a bit of a slump, he said, "I'll go back to the Hufflepuff common room first, I'm very sleepy now......"

"Okay, goodbye!" Matthew waved his hand at him.

Looking at Justin Finchrie's distant back, Matthew fell into deep thought.

The reaction of this Hufflepuff boy is undoubtedly a manifestation of the "Oblivion Curse".

The effect of the Forgetting Charm can cause a person to lose certain certain memories.

Moreover, he should belong to the kind of Oblivion Charm that is not very clever (or the wizard who uses this spell is of average level)...... Most of the impressions in his mind of the witch with the thick black scarf had been removed, but there was still a small afterimage.

So when someone mentions that image in front of him, he reacts differently.

So now here's the problem!

Why did the witch with the thick black scarf go to Justin Finchrie?

And the time she was looking for Justin Finchrie should have been after she had thrown her away through Duke Honey's tunnels.

Do you want to get some information about yourself through him?

If that's the case, then there's no doubt that she miscalculated...... Matthew and Justin Finchrie didn't know each other until today, and he knew very little about himself until then.

Or is his previous inference completely wrong...... The purpose of the witch with a thick black scarf was not to find herself at all!

She just wanted to grab a random little Hogwarts wizard and get some information out of her mouth.

The first target she found was herself, but she got rid of her through the tunnels of Duke Honey...... So, she turned her attention to Justin Finchrie, who was also in Hogsmeade.

Matthew's expression became a little solemn.

If this is the case, then the true purpose of the witch with a thick black scarf is debatable!

And, most likely, it has something to do with the previous series of attacks at Hogwarts.

......

"What are you doing here?" a cold voice sounded from behind him.

It was Agnes Lestrange, who was holding a rear admiral's hat in one hand and a cluster of flashing balloons in the other...... It looks like it's all small gifts fried out of colored packets and firecrackers.

"I'm sorry, I'm thinking about something. Matthew came to his senses and said softly.

"Let's go back to the common room?" Lestrange suggested, "Or do you have other travel plans now?"

"Nope. Matthew nodded, "Let's go back to the common room together." ”

The two of them walked side by side with strange Christmas presents in their hands and walked deep into the basement.

The cold, damp, and even somewhat eerie corridor fell into an awkward silence except for the footsteps of the two.

Matthew suddenly realized that he had known Agnes Lestrange for almost four months, and had a lot of contact, and even played Gobstone and Wizard chess together every day some time ago...... But verbal communication between each other is minimal.

In other words, they rarely speak.

"The previous assault ......" Miss Lestrange also realized that the atmosphere was a little strange, and as she approached the Potions classroom, she took the initiative to speak, "Do you think it's over?"

"Of course not. Matthew replied without thinking.

"So sure?" Lestrange gave him a strange look.

"It's just a reasonable guess. Matthew also realized that he had lost his words, and quickly explained.

"And you're so sure?" Lestrange snorted, "It's like you know something!"

Matthew didn't answer, and an awkward silence fell between the two again.

A few steps further into the Potions classroom, an abandoned washroom appeared.

Matthew turned his head and looked at it carefully, and the door sign in front of the bathroom door had the word "malfunction" written on it.

"This is the girls' bathroom!" Lestrange reminded.

"Of course I know, just looking. Matthew said blandly, "This shouldn't be a violation of school rules." ”

"In this bathroom, there have been people who have died!" Lestrange's voice suddenly became a little muffled:

"Almost fifty years ago, a Ravenclaw girl died mysteriously in it...... The then headmaster, Armando Duppet, closed the lavatory, and it was abandoned to this state. ”

Of course, Matthew is aware of this.

He also knew that the dead girl was called Myrtle, that she had become a ghost called "Weeping Myrtle" when she died, and that her killer was a basilisk that Tom Riddle had released from the secret room!

Wait a minute......

Matthew stopped abruptly.

"What's wrong with you?" Lestrange looked at him with some confusion.

"Nothing. Matthew spread his hands and continued towards the Slytherin common room.

......

After a few minutes, they stood in front of the serpent statue at the stone gate.

"Victory reigns!"

Matthew uttered the password for the past two weeks, and the stone door was opened.

Agnes Lestrange walked to her bedroom without looking back.

Matthew, however, stopped, as he saw a ghost around the corner of the common room.

Matthew hurriedly walked over and asked very respectfully, "Sir?"

Bloody Barrow raised his head and looked Matthew up and down, "What's the matter?"

"Is there a ghost in Hogwarts Castle called 'Weeping Myrtle'?" Matthew asked quickly.

"That's right. Bloody Barrow agreed.

"Have you seen her during this time?" Matthew continued.

"Myrtle rarely leaves her territory. The Bloody Barrot replied coldly, "Of course, I haven't seen her once since the beginning of this semester!"

"Okay, thank you!" Matthew bowed politely.

Then, too, he went back to his dormitory.
