Robyn Brown is the only sister wife left standing. But for Sister Wivespatriarch Kody Brown, she was always a prize to be won. When Robyn entered the family in 2010, she became Kody’s fourth wife, joining Meri, Janelle, and Christine. But fast-forward to the present, all three of them have left their spiritual marriages with Kody, expressing frustration with how the family dynamic shifted over time. For viewers (like myself), it was more of a relief than a shock. From the beginning of their TLC show, Kody made it clear who his favorite wife was. It seemed like he only ever cared about his marriage to Robyn, so their unintentional monogamous relationship now seems like a good fit, even though Robyn claims she’s unhappy.
