The third episode for "Sister Wives" season 6 will air this Sunday night and according to reports, the particular episode will focus on Kody Brown's marriage trouble with one of his wives.

So far, the sixth season has given much of its focus on Kody's divorce with first and legal wife Meri, as well as his legal marriage to fourth wife Robyn.

The upcoming third episode will now turn the focus over to another wife — Christine.

There's not a lot of story heard about Christine ever since the sixth season premiered earlier this month. But the third episode, which is entitled "Marriage Counseling Texas Style," should change that and fans will finally see more of her.

In addition, episode 4 will even go deeper into Christine's life as it will be entitled "All About Christine," and will feature her journey for the last five years of her life. This episode will also show the major events that transpired in that time frame.

As for the official synopsis for episode 3 it stated that "an anniversary trip to Texas turns into couple's therapy for Christine and Kody," and viewers can definitely expect that some drama will be brewed up between the spiritually married couple.

It remains unclear what will spark the tension between Kody and Christine, but International Business Times reported that it is highly likely that Kody's plural marriage may have something to do with it.

This speculation may have come from the episodes back in season 3, wherein Christine thought Kody's relationship with Robyn seems suffocating, reports stated.

Christine went on to describe that Kody does not divide his time equally among his wives, since he accommodates Robyn and her kids more. Christine also believes that Kody needs to develop their relationship too.

Show fanatics now think that Christine's thoughts about Robyn and Kody are still there.

Fans will just have to wait and see how Kody and Christine's relationship turns out when "Sister Wives" season 6 returns with a new episode on Sunday, Sept. 27 at 9 p.m. EST on TLC.
