Idk where this is headed on one hand Leon wants a warm family so you could be trying to repair that on the other hands his sisters are bro cons who don't see their brother as their sibling but as a romantic interest in addition Irina seems like a broken doll obsessed with Leon but at least for now I don't see their relationship taking a romantic turn. But at the same time you've basically destroyed any possibility of another step dad so I guess this may go that route? Well regardless it'll be interesting to see how that develops.
