On Friday’s ‘Sister Wives Talk Back’ episode, Robyn apologized to Kody for a joke about their marriage that didn’t land, and Meri reflected on her friendship with the Brown family patriarch’s last wife standing

Robyn Brown has managed to irk not only her husband, Kody Brown, but also her former sister wife Meri Brown.

Friday’s final part of the Sister Wives Talk Back special played back some of the highs and lows of season 18. In one clip from the finale, Robyn joked to Meri that “you never know if Kody and I are going to stay together,” resulting in both women erupting in laughter over the possibility.

And even though Robyn, 45, apologized at the time for her comments, her 54-year-old husband remained unamused.

As Kody sat seemingly emotionless while slumped onto the couch, Robyn made a nervous face as she tried to peep her spouse’s reaction from the corner of her eye. Placing her hand on Kody’s thigh, Robyn acknowledged how “that was really rotten” of her to do. But Kody looked at her and turned away.

“We have no idea what the future holds,” said Robyn, who also noted in the flashback that she had grown “tired” of “constantly” being lumped in with Kody during family disagreements.

Responding to that clip, Janelle Brown — who ended her own marriage with Kody last year — noted that Robyn “will get half or more of what Kody has if they divorce” because they are legally married. Kody had only been spiritually married to his three former wives, though Meri legally divorced Kody in 2014 so he could officially marry Robyn and adopt her children. (Third wife Christine Brown left her spiritual marriage to Kody in November 2021, triggering a 14-month “domino effect” that left Robyn as Kody’s sole remaining wife.)

Elsewhere in the episode, Meri and her best friend Jenn Sullivan spoke about their frustrations with Robyn, who was shown crying during the moment Meri chose to not renew her Arizona lease and end her marriage to Kody.

Not understanding “why it matters” and why Robyn was “so upset” by Meri’s decision, Jenn said, “You’ve been trying to build the relationship [with Robyn] and every time you try, you’re constantly disappointed.”

Meri — who has previously spoken about her friendship issues with Robyn — appeared to be upset as she looked downward. But she agreed with her friend, who also added that Robyn’s hope for the plural family to come back together again was “kind of selfish.”

“Even though she wanted it, there was nothing for you,” Jenn said. “So, I’m really struggling with that. She’s entitled to her feelings but I just struggle with she’s upset that you’re doing something good for you.”

To that, Meri said, “I would assume that she has a lot of mixed emotions surrounding it. Honestly, I think that she wants me to be happy and also wants that to include her and the family. I have no doubt that she’s got a lot of mixed feelings about it.”
