The Brown family continues having some major struggles playing out on the latest season of Sister Wives.

Kody and Christine Put Aside Their Differences

The tension among Kody and his wives seems to be at the highest level it has ever been this season-with him already having a major conflict with Christine-and things didn't improve when the family headed to Billings, Montana to meet fellow polygamists, the Collier family.

The battle between Christine and Kody finally came to an end-but only after Kody started railing on his wife for her PMS-which received the blame for her reaction to his old friend Ken being invited to join the family on their vacation.

Tensions Remain In The Brown Family

"From now on when you're acting like this, I'm just going to walk away," he told her in the episode. "I'm not going to have you rattle me to my core."

Kody then took the PMS bashing to Billings, working with Nathan Collier to dismiss the monthly deal each of their wives-Kody's four and Nathan's two-go through-which infuriated Janelle to the point that she then walked away.

"It frustrates me beyond belief when we're reduced to our biology," she said in the episode. "There's so much more going on with women than their biology and men are so quick to go, 'three days a month I don't have to do anything because she's on her cycle'-what the hell!"

Kody also went on to shift the blame of any of his wives occasionally feeling jealous of one another onto them directly-saying that it isn't his fault or responsibility to make sure they're always satisfied.

"I'm of the opinion that my wives need to be responsible for their emotional state-I can't own the wole thing-I can't deal with it," he said.

The issue-and Janelle's reaction-were later addressed on Twitter, where both Kody and his second wife justified the way they acted, while Meri addressed the fact that Christine owned up to PMS affecting her mood.
