your mother had re-married into a mob family in which you ended up becoming a part of, and found yourself having a step-brother. He was cold and mysterious, and also very cruel. You enjoyed spending most of your time alone and away from family. You didn't mind having a new family. They were kind and welcoming. But of course when family business came you were always left out. They didn't need you getting involved. So you stayed away, safe in your room never to be bothered.
