Yes, that was asinine. No matter what story she's been told, she has NO idea what kind of information might not have been shared yet. Toxic relationships can have zillions of layers of toxicity, and telling any patient straight off the bat that they need to initiate contact with the estranged parent for their own mental health is pretty astonishing. A patient could be repressing sexual abuse (or simply not trusting enough to share it yet). First order of psychiatric business for somebody with this level of eating disorder may be talking about childhood, but approaching that kind of delicate negotiation of boundaries with an absent/possibly hostile parent isn't something they are remotely equipped to deal with until they've dealt with their immediate households.
It also doesn't allow for the possibility (in my opinion possible here) that Dad stopped playing her games at some point and she cut ties with HIM at some point, and retroactively called it abandonment on his part. In my experience, people with this kind of narcissistic disorder can't tolerate being called on it, and will demonize anyone who refuses to accept their version of reality. I think her mother has done this as well (distancing herself from the antics and merely throwing money at the problem. Which, to be fair, is still generous of her.)
Not terribly keen on Christian, but I'm just as willing to believe that he was been telling her all along that he would go with her to get her started, and that it was contingent on her really truly committing to it, and that she insisted of course she would, this time would be different, everything would be amazing etc etc. The abuse/honeymoon/abuse pattern holds for male victims, too. If he chose the path of least resistance and agreed to go to Texas, but then instead of being grateful and optimistic in the preparations she was hostile, and then they got to Texas and the straw that broke the camel's back was her behavior in front of other people (on national television!) he may have simply concluded "oh, this truly IS never going to change. That makes it easy. Consider me gone."
While she wasn't too hard to read and he's obviously been doing this for years and will have a sense of what games people play, remember that the camera crew has been with them for quite a while (weeks?) and witnessed a lot of domestic interaction. Not sure how much advanced information he gets from them, but he certainly could have gotten a heads up about her domineering/his detachment, and it helps move the storyline along if he highlights the main issues between patient and support people.
Oh, yeah. First time ever in Dallas they "upgraded" me to a Cadillac. Like the kind of classic grandpa-smoking-cigars-level Cadillac I haven't seen in New England since the Nixon administration. Smooth ride, but had to do a 3 point turn in it and it took about 30 points.
To say something nice -- Maja certainly may be the best dressed poundticipant we've seen. Not sure where she sources her clothing, but others could take a page from her book. That said, she appears to have been much better off financially than the majority of people featured.
