'Sister Wives' star Kody Brown's remaining wife Robyn Brown said she's 'scared' Kody won't want to take on more wives in the future

• Robyn Brown said she's "scared" husband Kody Brown won't want to continue being polygamous.
• Kody is now only romantically involved with Robyn, but she wants to practice polygamy.

In a clip of the "Sister Wives: One on One" special People published on Thursday, Robyn Brown told host Sukanya Krishnan that she's "scared" her husband, Kody Brown, won't want to pursue future polygamous partners now that he's no longer romantically involved with three of his former partners.

Robyn also spoke about potentially encouraging Kody to seek other wives in the future, though he had "basically said no" to the idea.

As of late 2022, Kody announced that he was not romantically involved with any of his wives except for Robyn.

He and his third wife, Christine Brown, announced their split in November 2021 and consider themselves "divorced." In the December 2022 finale special, Kody and his second wife, Janelle Brown, announced they were "separated." Around that time, his first wife, Meri Brown, told Krishnan that he "made the decision" to end their spiritual marriage that had lasted more than 30 years.

In the clip of the recent finale special, Krishnan next asked Robyn if she'd ever encourage Kody to seek other wives in the future if he can't reconcile with any of his previous wives.

"I can... but I'm scared of it because of how badly this has gone," Robyn said.

Earlier in the same clip, Christine said that she couldn't see a situation where Kody marries another woman, even though he and Robyn "dream" of living a polygamous lifestyle.

"I don't think that they would go look for another wife after this," she told Krishnan.

Christine described polygamy as "a lot of work."

"And if you already have this much failure behind you, would you really want that again?" Christine asked. She also called Robyn and Kody "soulmates" and wondered whether there was "room for anybody else" in their lives.

The final part of "Sister Wives: One on One" airs on January 8 at 10 p.m.
