Slytherin's Defense Against Dark Magic class representative, Cassius Warrington, and Gryffindor's class representatives, the Weasley twins.
Although they had no idea what Douglas intended to do, they saw him draw his wand.
Clearly, it was nothing pleasant.
And so, the leaders of both sides put on very unnatural smiles.
They began greeting each other.
Fred spoke in the friendliest tone he had ever used in his life:
"Hi, Mr. Warrington, are you heading to class?
What a coincidence! We just finished ours!"
Cassius Warrington forced a slight smile.
"Yes, what a coincidence.
I hear you have Professor Flitwick's class next. You'd better hurry along.
The professor was just praising you Weasley brothers in class!"
George said in surprise:
"Oh, really? What did Professor Flitwick say about us?"
The moment he finished speaking, several snickers came from the Slytherin crowd.
The Weasley brothers' faces darkened.
They were certain that the invariably kind and fair Professor Flitwick had not said anything nice about them this time.
Warrington, standing opposite them, saw their expressions.
He raised his eyebrows provocatively.
In the end, out of respect for Professor Holmes.
Of course, the Slytherins were perhaps showing more respect for the wand in Professor Holmes's hand.
Gryffindor and Slytherin, for once, did not clash.
Both groups snorted coldly, then moved past each other.
For Slytherin's practical examination, the class representative went in first as well.
Perhaps because the Slytherin Common Room offered a view of the bottom of the Black Lake.
As soon as he entered the classroom and stood beside the pool.
Warrington quickly spotted the Grindylow underwater.
To Douglas's surprise, Warrington first cast a Bubble-Head Charm on himself before cautiously entering the water.
Under the normal curriculum, the Bubble-Head Charm was only taught in sixth-year Charms.
Although, in Douglas's eyes, Warrington's Bubble-Head Charm was very fragile and looked as though it might burst at any moment.
It was already quite an achievement for a student who had only just entered his fourth year.
Perhaps because of the confidence the Bubble-Head Charm gave Warrington, along with his having spotted the Grindylow beforehand.
He passed the first stage very quickly.
But in the second stage, when he faced the troll.
Perhaps it was the confidence he gained from secretly teaching himself upper-year spells.
Petrificus Totalus, Stunning Spells, Reductor Curses, and more flew at the troll's little head as though they cost nothing.
Unfortunately, his aim was terrible.
The troll either dodged most of his spells or took them with its body.
Just as the troll let its guard down, Warrington seemed to be preparing a powerful move, ready to land a decisive hit.
At that very moment, the Bubble-Head Charm that had remained around Warrington's head suddenly burst.
A foul stench hit him head-on, and Warrington instantly felt as though the top of his skull was about to blow off.
Then, caught completely off guard, he clutched his stomach and vomited off to the side.
Douglas genuinely had not expected this scene either.
What a bizarre way to fail.
The creatures in the fourth-year practical classroom were destined to have a very busy day.
Of course, the worst off was still the Grindylow in the first stage.
By the first afternoon lesson, during the fourth-year Hufflepuff class.
The seventh-year student responsible for looking after this classroom had no choice but to bring in the reserve Grindylow.
And let the other one have a proper rest.
After noon.
Word of the fourth-years' practical lesson had already spread like wildfire throughout the school.
It left the Lower Years thoroughly envious.
Especially when they discovered that many of the Dark Magic Creatures in the fourth-year practical lesson were covered in their own textbooks.
They grew even more excited, discussing whether, once they had memorized their textbooks.
They could challenge those Dark Magic Creatures too.
Compared with the Lower Years, the older years were even more abuzz.
If the fourth-year practical lessons were already so exciting, wouldn't the fifth-year practical lessons have even more in store?
The sixth-years who had chosen Defense Against Dark Magic, meanwhile, trembled.
Since Professor Holmes could bring so many textbook creatures into the classroom.
Didn't that mean the contents of their textbooks would also be brought into their textbooks?
After all, their very first lesson had covered Inferi.
At that moment, although they had already finished the previous lesson's homework.
They still felt their understanding of Inferi was very shallow.
They all rushed to the library and began looking for books about Inferi.
Those who had not been accepted into Defense Against Dark Magic were utterly envious.
They all felt that, if Professor Holmes had been teaching them Defense Against Dark Magic all along.
Their Defense Against Dark Magic grades certainly would not have been so poor.
Regardless of how Douglas had once again thrown Hogwarts into utter chaos.
His lessons continued in an orderly fashion.
After finishing the fourth-year lessons.
He still had a second-year Gryffindor lesson and a sixth-year lesson that afternoon.
Douglas looked at the two sets of homework that had been collected.
He could not help rubbing his head. Was I assigning homework to them, or to myself?
Upon hearing Hermione report that everyone had memorized the contents of the previous lesson.
Douglas first glanced at Neville, whose face was full of excitement.
He had heard from Hermione that, to avoid holding everyone back, Neville.
Got up at six every morning and began memorizing the text in the common room.
So Douglas first gave Neville an encouraging look, then generously awarded Gryffindor twenty points.
Then, as all the students looked at him hopefully, expecting Douglas to lead them in challenging the Dark Magic Creatures too.
He simply instructed Hermione to lead the students in reading the second passage aloud twice.
Then, once again, required them to memorize the entire text.
A chorus of groans rose from the students at first, but under the urging of their class representative, Miss Granger, they were soon filled with enthusiasm again.
"Everyone, don't forget what the professor promised us.
Once we've all memorized the entire text, he'll take us for practical lessons..."
Douglas was very satisfied with Hermione's response.
He felt that, besides having the brains of a top student, this little girl even had the potential to become a politician.
If his memory served, Douglas felt sure he had heard in his previous life that Hermione would enter the Ministry of Magic after graduating.
Sure enough, a person's future showed from childhood.
While the students memorized the text below, Douglas quietly cast a See No Evil, Hear No Evil Charm on himself.
Douglas had invented this charm himself.
Its purpose was to place the person under the spell in a soundless environment.
An effect similar to earplugs.
He had always remembered there being a Muffliato charm, but he had searched through many records concerning spells.
And had never found that charm.
It was not as though he had never considered whether the charm might have been invented by Snape, the Half-Blood Prince.
Unfortunately, he had once searched the cupboard of old textbooks in the classroom.
Only to discover that there was no copy of Advanced Potion-Making inside.
Later, he asked an older student, a sixth-year Hufflepuff who took Snape's class, and only then learned.
The sixth- and seventh-years used a different classroom from the Lower Years.
Since advanced potions usually required more time, those two years had a separate classroom.
Douglas had originally planned to wait until his sixth year.
Then quietly get hold of that textbook.
After all, besides the few spells of Snape's own invention recorded in it.
It also contained many of his insights into Potions.
But who could have imagined that Snape would not even give him the chance to choose Advanced Potions?
Hmph! Pride and prejudice!
Douglas deeply despised Snape.
