The Mistake

"I attacked Malfoy first, because he was the one who insulted Hermione."

"Why would you resort to physical violence? Wouldn't using magic have been more efficient?"

A sly smile formed upon Arth's lips.

"I was considering using magic however, I knew that using magic against another student to solve conflicts would've gotten me a free ticket out of Hogwarts. While fist fighting isn't ok, it will bring about less consequences that casting a stunning spell on seven people."

"Interesting way of thinking."

"Plus, if the Slytherins complained about how I beat them seven versus one, then they would've been ridiculed on how they lost a fight when they had an overwhelming advantage."

"How did you exactly win against seven people? It is not that I am doubting your abilities but please understand that it is hard for me to believe that a second year beat a group of kids when most of his victims were at least twice the weight of the perpetrator."

"I wouldn't say they were victims sir."

Dumbledore raised an eyebrow.

"I just received a letter from madam Pomfrey stating the extent of the damage done to the Slytherin team. While they can indeed be healed, it would have caused no small amount to them."

"I guess I did go a little overboard..."

"A little? I do say it was a tad bit more than a little, but no matter. People often times do need a moment to vent their anger and frustration. But I must ask, why did you cast a memory charm on all of them?"

"I decided that it was better to eliminate any chances of getting in trouble. Plus, I didn't want them to become wary of me."

"And why do you wish that?"

"First of all, I found it troublesome. Rumors would start to spread and it would be a pain to deal with the consequences. Plus, they won't come back to pick a fight if they are wary of my strength. How will I relieve my anger?"

"However, did you not use magic on other students? Isn't that punishable by expulsion?"

"That is indeed true, however, they can't prove it without it benefiting me."

"What do you mean by that?"

"You see, during the scuffle, one of the boys broke my wand-"

"That means that you casted the memory charm without the aid of a wand! You managed to achieve something that most adult wizards can't do!"

"So even if they do prove that I had altered their memory, when I get expelled, I can use the fact that I can cast spells without a wand to get a job."

"The Ministry of Magic's Department of Magical Law Enforcement will be delighted to have you join their ranks."

There was a twinkle in Dumbledore's eye as he stared at Arth from across his table.

"Fascinating, absolutely brilliant. I haven't seen a mind like yours in a century!"

"Why thank you headmaster."

Dumbledore took a quick glance at his clock.

"Well, after hearing your exciting mind process, I believe it about time you go back to your friends, they must be worried sick."

Arth got up and did a fancy little bow.

"Then I shall excuse myself."

When Arth had reached the door, Dumbledore called out.

"Mr. Kingscrown, I shall make sure that you will not be expelled for your recent fiasco, however, whether you get detention or not is up to your house teacher. And one more thing, you made a mistake."

Arth winced before going down the stairs.

Professor McGonagall would never let him off without at least serving detention. However, what exactly did Dumbledore mean by I made a mistake?

When he reached the common room, he was swarmed by a crowd of Gryffindors.

"Arth! I heard that you beat the Slytherins seven to one!"

"Arth! You are a bloody legend! Can't believe you beat the Slytherins by yourself."

"Is it true that you broke sixteen bones?"

Arthur then realized the crucial mistake he had made. He had erased the minds of Slytherins, but forgot to erase the minds of the Gryffindor Quidditch team. With the Weasley twins gossiping like middle age women, the whole school probably knew what Ahmad happened. It entirely wasted Arth's effort to wipe the minds of the Slytherins.

Arth groaned before staring at the crowd in front of him with a tired gaze.

"Hey Fred!"

Fred glanced over from the corner where he was once more singing a ballad of his achievements.

"What is it Arth? Do you also want to hear the song I made?"

"Did you tell the whole school about my fight?"

"Nah, we only got to our house. Was thinking about telling the whole school during lunch."

Arth sighed in relief.

It seems that he only had to wipe the memories of the Gryffindors.

With a dangerous glimmer in his eyes, Arth stared at the crowd with his hands raised up. The air teemed with power and everyone started to unconsciously back away from Arth.

"What are you trying to do mate?"

"...Is this some kind of joke? It's not funny."

Arth ignored the scared gazes of the Gryffindors as he attempted to create an area of effect memory charm.

However, he failed.

Arth gave up and sighed.

The air slowly went back to its normal state.

"That was a joke right Arth? Cause that was really scary."

Still ignoring Fred, Arth rolled his eyes before mumbling to himself.

"Guess I have to do it the hard way... one by one."

Arth turned towards Fred and muttered in a clear voice.

"Obliviate."
