Harry Potter and the Secret Treasures

After Ron heard what Evan said he jumped up and stared at him.

"You say I purposely cast a curse that I have never heard of," shouted Ron

"That's funny, you've just used a powerful corrosion curse on me and you're telling me you've never heard of it." said Evan as he flicked out his wand and pointed it at Ron, "Unfortunately I've seen this spell in a book about dark magic before and the description is exactly the same as the one you used."

"Evan, calm down!" said the others quickly as the stood to their feet.

"Ha-ha, that's hilarious." said Ron as he drew his wand, "I finally understand, it must have been that book that gave you the illusion that I was attacking you with dark magic."

"I'm calm and I know what I'm doing."

Evan calmly said, "Give it up, Ron, if I go find Dumbledore..."

"Nooo!"

"I don't know what you're talking about, no matter what I'm not going with you. I'm going to bed."

He had just taken two steps when he suddenly stopped in place, his wand lightly quivered. The common room suddenly turned gloomy.

"Ron, are you all right?" asked Harry, worriedly

There wasn't an answer, there was just an eerie silence.

"I don't think Evan meant anything, he just..."

Before Evan words were finished Ron turned and pointed his wand at Evan, it produced an eerie green light. But before the spell was fully cast Evan subconsciously fired a spell, interrupting it.

Ron slowly fell down making everyone else dumbfounded.

After a few seconds Ginny's scream echoed in the common room, she quickly ran towards Ron.

"Evan what did you do?" said Harry while panicking, "You attacked Ron."

"He attacked me first, you should have seen the green light that his wand was producing."

"What was it?" asked Hermione eagerly.

"If I'm not mistaken, it was the killing curse, he was trying to kill me," said Evan as he recalled the green light which made him think of the Avada Kedavra curse.

"An unforgivable curse, that's impossible!"

Hermione gasped while the others were confused.

"Hermione, what do you mean by an unforgivable curse?"

"I have read in books that there are three unforgivable curses, The Killing Curse, The Cruciatus Curse, and The Imperious Curse." explained Hermione, "They are extremely evil, dark magic, once used, you will get a one-way ticket to Azkaban."

"Azkaban?!" said Colin with a trembling voice, "Evan said Ron was about to attack him with the Killing Curse."

"I don't think it was Ron, something must have been controlling him!"

Since being attacked by Ron in the Great Hall with the corrosive spell, Evan knew that this wasn't a spell that a second year could master especially one with a broken wand.

Was it a coincidence?

But even if there was a mutation, there should be a limit.

Think of Ron spells in the past, except for catching a few things on fire, or making him vomit slugs for a week, he can't do much.

When duelling with me, he suddenly produced a powerful dark magic, it's too suspicious. But if Tom Riddle was controlling him, everything can be perfectly explained.

As a student, Voldemort must have read countless dark magic books.

This also explains why Ginny didn't know anything about the diary.

Evan sighed, if all goes well the Chamber of Secrets will be settled soon.

There won't be any more attacks, and Riddle won't control Ron in front of Dumbledore. When he wakes up, he will know where the diary is hidden. The Mandrakes will mature soon, Snape will use them to brew an antidote.

"But I don't understand who would control Ron?" said Harry cautiously, "And what is his relationship with the chamber?"

"That doesn't matter, the question is what do we do now?"

Hermione was looking at the door with anxiety. Evan was holding his wand, Ron was laying on the floor like a corpse, and Ginny was crying beside Ron. If someone else saw this how would they explain it to them?

"Let us go to Professor McGonagall or Dumbledore, they will know what to do."

In the hospital, Dumbledore stood in front of Ron's bed with an unusually serious face.

Beside him was Professor McGonagall and Snape, who was bending over examining Ron carefully.

"Albus, Weasley, this is...…." said Professor McGonagall, Worried.

"A powerful curse is cast on his soul, poor child, he must have not known what he was doing," said Dumbledore as he gazed at the still resting Ron.

"Obviously, this is why Weasley with that empty head of his can suddenly cast such a powerful corrosive curse." said Snape as he looked up in disgust, "But luckily he hasn't been cursed long enough to become an idiot who knows nothing."

Snape took out a bottle of potion from his bosom and poured it down Ron's throat.

At the same time, Ron awoke, he stared at them with a confused expression.

"Where am I?"

Then he noticed the Professors standing beside him and with a surprised tone said, "How are you, Professors...."

"Thank goodness you awoke, Weasley!" said Professor McGonagall, "You were under the Imperious Curse!"

"Imperious Curse?"

"Yes, it is a very wicked dark magic, the people who are put under this curse loss their free will, it allows one to control the minds of others."

"But I don't remember anything, what did I do?" asked Ron as he shook his head.

"You used a corrosive curse on Mason, and afterward you tried to kill him with the Killing Curse." Snape said with a slight sneer, "But you obviously didn't succeed, with your poor magic strength, even if it hit him, I suspect it will only give him a slight nosebleed."

"But I...…"

"Mr. Weasley, it isn't your fault, even some powerful wizards are susceptible to the Imperious Curse."

Dumbledore said with a dignified expression while looking at Ron and gently said, "But I must ask you, do you have anything you wish to tell me?"

"No, no!" said Ron while looking pale, he didn't know what to say, and hesitated for a long time before he softly answered, "I don't remember anything, Professor!"
