Christine seems unhappy and defeated. It was sad when she expressed how jealous she still gets. You have to wonder what she expected when she became a third wife.
she expected what is the 'norm' for modern day polygamists-to be the last wife (the robyn in the situation-the youngest and newest who got to spend the most time w/kody, had the youngest kids with kody...). robyn wrote in one of the books that most plural marriages this family knows of consist of only two or three wives. four wives is a rare occurrence. christine said early on in the series that she always only wanted to be a wife #3 because that way all the hard adjustments and jealousy issues going from one wife to two have been worked out so it's easier for the third to come in who doesn't have to deal as much with it. i'm sure when the idea of a 4th coming in was brought up it came as a shock to her.
christine has changed allot over the years-she used to be the one who was always agreeable, went along with everyone else, did what kody wanted.......she's finding herself.
