This thread has inspired me to go back to the beginning. I've watched from the start but it's been awhile. I'm completely blown away by how different the family is from season 1 to now. They honestly seemed like a huge, loving family. All the wives seemed happy and to genuinely care for and like one another. Kody and Meri had chemistry and seemed pretty happy. I did think it was interesting that Meri is the one who started things with bringing Robin into the family, but then she experienced a lot of jealousy. Christine even said she wanted nothing more than for them all to live together, when Robin was being courted. Now she says that's the last thing she wants. Now they just seem like neighbors who hang out from time to time.
On another note, Meri seemed to gain quite a bit of weight between season 1 and season 2. Perhaps the stress of a 4th wife and coming out as polygamists. I had forgotten that.
Personally, I'm super bummed the show is ending. I've been a pretty loyal follower, and I watch very little reality tv. I find the whole concept so interesting.
