Because when Kyle and Connor walked down the stone steps of the underground classroom and came to the Potions classroom, they suddenly found Umbridge sitting in a dark corner at the back, holding the familiar writing board in her hand.

Others also saw it, and there was a burst of discussion in the classroom.

"Strange, why is she here again..."

"Does the professor have to be investigated twice?"

"That shouldn't be possible. All other classes are just one time..."

"Maybe Professor Snape is different. You know, he's not that likable."

"Nonsense, Professor Snape is the best!" The last person to speak was obviously a Slytherin.

But no matter what, everyone was very curious and didn't understand why Umbridge had just investigated Professor Snape in the Potions class, but came again in less than two days.

Umbridge herself was equally curious. She listened to the discussions of the people around her and looked at the contents on her clipboard, feeling a little confused.

Why did everyone say she had been here, but there was clearly no investigation result about Snape on the clipboard?

"Quiet!"

At this moment, the door of the classroom was suddenly pushed open.

The whole classroom suddenly became silent.

Snape strode in, glanced at the corner, and his expression suddenly became very ugly.

Kyle also noticed their expressions and couldn't help laughing out loud.

But immediately, Snape, hearing the noise, turned around and glared at him fiercely.

Kyle quickly shut his mouth, but his shoulders were still heaving, and it was obvious that he was enduring it with great difficulty.

Kanna looked at him and asked curiously, "What are you laughing at?"

"How interesting! It seems that Professor Snape has overreached himself." Kyle said in a low voice.

He knew very well that Umbridge's investigation of other professors would be sufficient only once, and there was no need to attend classes twice.

Now that she appeared in the Potions classroom again, it could only mean one thing... She had forgotten she had been here.

In other words, Snape used a forgetfulness spell on her, causing her to forget some things, including the results of her investigation into Snape.

To be honest, the effect of this Forgetfulness Charm is really not very good. Umbridge has forgotten too many things, even the lessons she had attended. And then it happened again today.

This does not have the effect that the spell is supposed to have.

Anyway, Kyle felt that if it were him, he would only make Umbridge forget some necessary things...such as the questions she asked after class.

This is the solution to the problem.

But then again, Kyle was quite curious about what Umbridge had said that made Snape cast the Oblivion Charm on her.

But just when Kyle was about to tell Connor this, he looked up and met Snape's eyes.

His eyes were cold and emotionless, as if he would kill someone to silence them in the next second.

There was no choice but for Kyle to shut up and say nothing.

Snape's expression softened a little.

"Today we are learning about the Joy Potion..." He calmed himself down as if nothing had happened. "This is a potion that requires a lot of patience to brew successfully, because you have to keep an eye on the color changes of the potion in the crucible. Only in this way can you complete the next step at the right time..."

"The instructions..." He waved his wand, "...are on the blackboard. Start now."

Everyone immediately forgot about Umbridge and got busy.

"Albizia Julibrissin... unicorn hair... peppermint..."

Kyle checked his materials and after confirming that there was no problem, he began to grind the roots of the Albizia Julibrissin.

Umbridge had been very quiet for the first half hour, but Kyle knew that she was about to take action.

Because that's how she was the last time she came.

She glanced at the crucible of students on both sides.

"This class seems to be full of excellent students." Umbridge said, "The Joy Potion is a great potion. It can make us feel happy. We usually need a little happiness."

"But this kind of happiness is false." Snape said slowly: "And if you take too much, there will be side effects..."

"I don't think that's a problem," Umbridge said briskly. "Just drink less. If the ecstasy potion was really that dangerous, the Ministry wouldn't allow it to appear in the curriculum, would it?"

Snape sneered twice.

"So, when you were at Hogwarts..."

"I've been teaching here for fourteen years," Snape said before she could finish her sentence.

Umbridge was stunned for a moment, but didn't care and just made a few strokes on the writing board.

Kyle crushed the petals of the albizzia with the back of his knife and tilted his head to observe them.

Seeing Umbridge put down the writing board, he subconsciously whispered:

"Did you apply to teach Defense Against the Dark Arts first?"

The next second, Umbridge asked the same question, without changing a word.

really……

This further confirmed Kyle's guess that Snape was the one who cast the Oblivion Charm on Umbridge.

However, at this time, the preparation of the ecstasy potion had reached the most critical moment, and everyone's attention was on the potion in the crucible. Except for Kyle, no one else noticed this.

The same question was asked again, which made Snape very annoyed, but he had no choice. In order not to attract more attention, he could only cooperate with Umbridge and answer those questions that seemed meaningless to him.

What happened next was also unchanged.

After asking Snape, Umbridge began to walk around the classroom, pretending to check the potions that everyone had brewed.

The reason why it was called pretense was that Umbridge knew nothing about the process of brewing a potion of joy, but she actually praised a student whose cauldron contained pink potion.

The real cheerleader should be a blue color before adding the unicorn hair.

The pink color is because the order of adding the ingredients is wrong. The dried petals of the albizzia tree were added first instead of its juice.

There was a burst of chuckling all around. The student who brewed the potion incorrectly blushed, lowered his head and said nothing. Even Snape, who was at the front, curled the corners of his mouth slightly, as if he was laughing at Umbridge's ignorance.

Only Umbridge stared, not knowing what the others were laughing at.

By the end of the get out of class, everyone had poured the finished stimulants into the bottles.

Almost everyone's potion was a light gold color, except for the person she praised, whose potion was a different color from the others. Umbridge then realized that she had praised the wrong person.

But she pretended nothing had happened and walked towards Snape again.

Kyle's eyes lit up.

The last time Snape cast a forgetfulness spell on her during their private conversation... She would definitely say the same thing this time.

Kyle deliberately fell to the back, loosened his grip, and dropped a few pieces of parchment on the ground, trying to delay leaving the classroom.

He had done just that last time in Transfiguration.

However, this time, before he could pick it up, Snape waved his wand violently.

The parchment on the ground, including Kyle himself, was immediately blown out of the classroom by a gust of wind.

then……

Bang! The classroom door was slammed shut.
