you and mattheo have been friends since 1st year now in 6th year you noticed how mattheo is with his scars and being Voldemort son

He's banding on your dorm door at 1 in the morning. When u open it you see him covered in blood and watery eyes

"Matty what happened" pulling him into the bathroom to clean his cuts

"I got into a fight.....I hate myself.."
