Disclaimer: I do not own the Harry Potter world, so I did not make any money writing this short story.
A scrawny, black – haired boy stood up in the midst of the Great Hall. Instantly, all chatter ceased.
"Harry." A bushy haired witch spoke up. "What are you doing?" Confusion was written on her face.
"Silly girl. Are you really so blind that you can't tell who I am? Harry Potter is GONE. Due to his…connection with me, I have, shall we say, complete control over him. Harry isn't dead, though I believe that you will wish he was."
Realization sunk in. The students though quiet before, became dead silent. A scream disrupted the noiseless hall.
"You monster!" Ginny cried. "Why would we ever wish Harry was dead?"
"Because Harry is still here, even if I am possessing his mind and body. He will be able to watch, in horror, as I torture him in the only way possible. I shall kill all of his friends, his mentors, all of the ones who are helpless. Dear Harry cares nothing about himself, he can't care less how he's doing. The only way I can hurt him, the only way anyone can hurt him, is to show the ones he cares about in pain. Nothing could hurt his soul and mind more. Except for one thing. He being the one making his friends feel pain."
The black – haired boy waited a bit before continuing his speech. He enjoyed listening to the quickening breaths, watching the faces drain of color. He was a cat playing with a mouse that had already been caught.
"So… who will be first?" He asked as he pointed his wand at each one he listed. "The know – it – all? The red – haired git? The girl he loves? The loony Ravenclaw? Or… yes! The meddling old coot. The man he thinks of as a grandfather. Dumbledore."
The boy raised his wand, a malicious grin on his face. "Avada kedavra."
The silence ended with those two words. There were screams all around, and teachers were trying to bring order back to the panicked students. It wasn't working. Chaos reigned as everyone tried to shove others to the side as they rushed to the double doors.
A single word was uttered. "No." However, no one heard the scrawny, black – haired boy.
