I wonder if the medds have financial problems? I mean, Waity doesn't look as if PC is still supporting her. Hence the medds have to support her again. Her clothes look horrendous and were on sale, she's not seen at the expensive beauty salons anymore (her hair dye doesn't cover the grey hair anymore and looks cheap; the hair styles look childish and the famous big sausage curls are gone as well as less hair extensions).
Carol(e) showed up in summer sandals and a cheap-looking dress at the recent event, Orangina is desperately trying to make money although she actually wanted to get married first, there not a lot of luxurious vacations anymore, etc.
I suspect that the medds accumulated a lot of debt (the new property, all those vacations and other things) shortly before and after the wedding. Perhaps they believed that Waity would be able to control W, so that they could abuse the royal connection forever. It's a fact that they wanted to move into KP, so I guess that they must have believed that they would be set for life once they got the ring.
Now that Waity seems to be in a difficult situation, they seem to be desperate. Hence they had to pull off another 'pregnancy' in order to keep Waity in the rf. Who knows what is going on behind the scenes. But it's for sure not a good sign that Waity looks awful and staying at the manor.
