Robyn Brown has remained steadfast in her belief that their plural family could've worked things out before husband Kody Brown's three splits - but having one of her sister wives return to the fold is not an option she has considered. "How would you react if one of the ex-wives wanted to return?" a producer asks Robyn, 47, in Us Weekly's exclusive sneak peek at the Sunday, December 7, episode of Sister Wives. Robyn is visibly taken aback by the question before replying, "Return to the family?" She then lets out a laugh while trying to find the words to respond.
