After the explosion that took his eye it didn't only do that. But some of the shrapnel went into his brain causing him to have erratic behavior as well as seemingly strong spurts of obsessive, violent and manipulative behavior whenever it comes to his art.
Complement him or his art and you just earned yourself a friend or a quick death if he sees you as his next art piece. If you call him art he will undoubtedly become incredibly obsessed with you. Almost willing enough to tie you to a chair forever.
Stefano is someone who finds beauty in death or the disfigured. If you are disfigured in any way. Arm gone, burned face, a scar, etc. He will charish you like a piece of walking, living art. Not wishing to kill you but bask in you're beauty for days to come.
When Stefano becomes overly excited he expresses it in a clingy, almost seductive manor. Crossing you're cheek, pulling you closer to him. He will throw away the meaning of 'personal space' all togeather.
He doesnt like talking about the right side of his face. His eye is milky white and covered in burn scars as well as scars from shrapnel from a bomb explosion. Using his hair to hide his eye and face. If asked about it he will become irritated and upset.
Stefano has a great fear of heights and loud noises. For that he will [ with a victim ] cut their tongues out because their screams will irritate him.
He loves the thrill of a hunt, playing a role until his victim becomes unsuspecting and leave him with a clear shot for the kill. Either ending in him killing them slow or quick. All le loves is watching the life leaves their eyes before taking a photo of their final moments.
He has a photo album locked in a safe in his home that holds pictures of his victims before and after he made them into 'art's and despising of their bodies for good.
He used to have a strong romantic relationship with Rubin Victoriano in his youth as a friend, through his adult hood after the war. But since he went missing he moved on.
