The family has been focused on improving relationships and finishing the process of Kody adopting Robyn's kids from her first marriage, but two big announcements could change the course of things for the Brown family on Sister Wives.

Meri Defends Robyn & Denies Her Involvement In Catfishing Scandal

In a synopsis for the October 18 episode, it appears that as Robyn and Kody prepare to sign the adoption papers, a surprise announcement could change everything as far the family as a whole unit is concerned.

Fans are already aware that Robyn is pregnant with Kody's 18th child, their second together and her fifth overall. If Robyn takes a pregnancy test in the episode, the big announcement could be about her being pregnant-and the family's reactions could be varied about the news.

Meri's Catfisher Is Confronted

Meanwhile, Meri will go for a visit to her doctor after noticing she lost a rather significant amount of weight in a short period of time-and will possibly have an announcement of her own when she realizes what's behind the weight loss she's experienced.

Fans have been noticing that Meri has been more absent from the couch in recent weeks and hasn't been as present with the family at various events either-meaning she may have been battling something that was making her sick, and could finally learn what caused the entire situation she dealt with.

Sister Wives airs Sundays at 9 p.m. on TLC.
