Season 20 of Sister Wives kicks off with a seismic twist that leaves fans stunned and the Brown family in utter disarray. After a turbulent few years marked by crumbling relationships and public fallout, Kody Brown drops the biggest bombshell yet: he may have secretly taken on another wife—without telling anyone, not even Robyn.
Rumors begin to swirl early in the season when eagle-eyed viewers notice Kody disappearing for long stretches without explanation. He offers vague excuses about “business trips” and “personal time,” but his evasive behavior raises eyebrows—especially Robyn’s. Her instincts sharpen, and the emotional cracks in their once-solid alliance begin to show.
The truth finally explodes in a late-season confrontation. Robyn, already emotionally worn from being Kody’s last remaining wife in what’s become an unintentional monogamous marriage, breaks down in front of the cameras. Tearfully, she confesses that she suspects Kody has been seeing someone else—and not just dating. “He’s hiding something,” she says. “And I think he already made a commitment without me.”
Tension escalates when Janelle and Christine, watching from the sidelines, begin connecting the dots and suspect Kody’s reversion to plural marriage isn’t a return to family values, but a personal ego trip. “He couldn’t handle the rejection,” Christine says. “So now he’s starting over—with someone who doesn’t know who he really is.”
Eventually, through a combination of insider tips and emotional pressure, the truth is confirmed: Kody has indeed formed a new spiritual union with a woman outside the public eye. He has not legally married her—but by his own spiritual standards, it’s a done deal. The reveal stuns fans, producers, and most of all, Robyn.
In one of the most emotionally charged moments in Sister Wives history, Robyn confronts Kody during a private sit-down. She pleads with him for honesty, visibly shaken by the betrayal. “You promised me we’d walk this path together,” she sobs. “You said I was your last.” But Kody, visibly conflicted, says he felt compelled to return to his spiritual roots, to re-establish the “principle” that was supposed to define his family from the beginning.
Robyn is devastated. For years, she had endured accusations from fans and family members alike that she had dismantled the plural family. Now, she’s forced to reckon with the fact that she wasn’t the final chapter in Kody’s story—just one of many turning points. She retreats from filming for several episodes, leaving producers scrambling to patch together narrative continuity.
