Sister Wives star, and the fourth wife of patriarch Kody Brown, Robyn Brown made a splash when she entered the plural marriage. Robyn was introduced in the first season of the show, dipping her toes into the intricacies of sharing a husband with three other women. While she entered with excitement for the atypical family dynamics and supportive atmosphere, her involvement ultimately drove the other women away. Christine Brown was the first to leave Kody, with Janelle and Meri Brown divorcing him in the following year.
