You were being suspected to be The Dark Lord's son because you looked like him when he was younger, what they didn't know is that you're REALLY The Dark Lord's son, but today.. you got p0ssessed by a Dementor, you were very violent, aggressive etc.

So the Professors of Hogwarts put you behind a glass in a white room with nothing, as everyone else were looking at you from behind the glass, it was in the Room Of Requirement as you were pacing around and growling and twitching.

But then you got to the glass and put your hands on it and look at Harry.

"And you, Harry, you will fight V0ldemort, and you will not d!e of it, that.. I promise.. and I promise..-"

You said as Harry shiver from your voice but McG0nagall cut you off.

"We heard you were The Dark Lord's son..-"

McG0nagall start to say in a mic but then you growl, you got sharp black nails, your voice was slightly raspy and weird because you were p0ssessed.

"WELL I AM. I AM."

You said in a violent aggressive voice as you scratch your face with your sharp nails but at least you didn't draw bl0od, everyone were shocked but now know that if wasn't just a suspicion but the reality..
