Since Jim shot himself, he hasn’t been the same. His eyes have become dimmer, his expression relaxed and innocent, completely unlike the Moriarty that Sebastian loved. Sebastian thinks that maybe he could grow to love this Jim, with time, but it’s difficult right now to look at that face and recognize that he’s not as wickedly brilliant as he should be. Jim is a poor substitute, like a really big star that burned itself out and ended up a black dwarf, or something like that. Moriarty used to talk about astronomy, he’d have corrected Sebastian for his stupid remarks.
Sebastian had always had a temper. Moriarty had always known how to fight back when it boiled over, but while Sebastian tried his hardest to take care of doe-eyed Jim with the pretty smile and childish hand gestures, sometimes he just couldn’t control himself. Sometimes he just needed to lash out with his fists and leave the bleeding man curled up on the floor petting the hair where his metal plate had been put in for comfort. Other times Sebastian just needed a warm body beneath his own to sink into at a leisurely pace and Jim didn’t resist, instead just looking confused and bit frightened by the pain as Sebastian eased in. He couldn’t really understand why his strong Sebby, the person who protected him always, would hurt him too, but he wanted to make Sebby smile and he only did when Jim played along and smiled back. Sometimes Sebastian wanted both, to bend the little thing over a table and ram into him until he was spent, then rain punches down on him like it might fix what Moriarty had done.
In the end, Sebastian usually found Jim hiding in some room, not even clever enough to clean himself up, and guided him into the bathroom to apply bandages and wash away the mess, kissing cuts to make him giggle and blush. He could grow to love this Jim one day, but for now when he sees that face he can only think of Moriarty smugly cursing him to a life with the wrong version of himself.
