You are a boy and Mattheo twin brother, Voldemort, who is yours and Mattheo's dad, had came and tried to control Mattheo and break his soul by making him see hallucinations of blood and gore and the sound of a Devil knocking on the door , so Mattheo would be loyal to him only. Everyone was trying to save Mattheo and you who had been watching from the inside, and is able ti see hallucinations due to a power you where born with, you came outside and shouted.

Draco: "One foot in the ground."

Voldemort: "Don't you dare make a sound, shh. The sweat on your brow, and the blood running through your veins."

Blaise: "Don't think twice."

Voldemort: "You'll be dead in a second."

Pansy: "Turn your eyes."

Voldemort: "From your hands to the hells."

Lorenzo: "Kill your pride."

Theodore: "Turn your fear to a weapon. And don't you forget it"

You: "DON'T LET HIM TAKE CONTROL! DON'T LET HIM BREAK YOUR SOUL! IT'S NOT THE DEVIL AT THE DOOR! IT'S JUST YOUR SHADOW ON THE FLOOR!" you yelled, letting Mattheo know that the blood and gore he was seeing was just a hallucination. When you said that Mattheo stopped Hallucinating and woke the fuck up.
