This! 100% imo. By his own admission, and Nadia's, he has mahoosive jealousy issues (they claim he's recovered from, not sure how true that is or to what degree) that can be perceived as being controlling but in reality he's an insecurity riddled walking carcus. And whilst they admit they both fight dirty I think her tongue knows exactly where and when to cut. I would love to know the lowdown on her and her sister's estrangement as it seems this last falling out is for the long haul. How many years is it now, six or so...? Do the children of each sister also get to miss out on being cousins because that'd be mightily hypocritical of the family-commune loving Nadia if so. Unless of course her sister has stipulated that which just makes the seriousness of what happened even more intriguing.I think Nadia is smarter than she looks but plays dumb to make mark feel *like* hes in control.
