It appears like not everything is going good in Kody Brown's family as the polygamist has a huge fight with his third wife Christine in the last episode.

The couple had a showdown after the family patriarch decided to meet an old friend who denounces his lifestyle.

However, the ugly fight is not the only thing the Brown family will have to deal in the upcoming episode.

Kody along with his four wives, Meri, Janelle, Christine and Robyn, will welcome another polygamist family, know as the Colliers.

Nathan Collier, the head of the house, has two wives and eight children out of which five are at home while the eldest three have moved out.

"I dated them at the same time, courted them at the same time," Nathan tells the Brown family.

"We're not going to hide our family," Nathan explains about how the society reacts to their lifestyle.

"The people who accept it, that's great. The people who condemn us, we dismiss it. We don't give them a second thought," he said.

The episode synopsis reads:

"The blow-up between Kody and Christine continues as they approach their final destination. Can Kody get to the root of the problem? Later, the Browns meet another polygamist family, the Colliers and discuss the idea of the Colliers courting another wife."

TLC's family reality show airs every Sunday night.
