When "Married at First Sight" season 4 returns to the small screen with the episode "In-Laws," fans will be able to catch up on Sonia and Nick, whose marriage took a turn for the worst in the latest week of the show.

In the previous episode of "Married at First Sight," Sonia decided to move out of the house and leave her husband alone as things started to become more out of control between them.

Nick's infamous "I am not attracted to her" outburst when his wife asked him to "open up" and then lying about sleeping with her just drew the last straw for Sonia.

However, it looks like things will change in "Married at First Sight" season 4 episode 12. A promo for the episode shows Sonia reassuring her commitment to the experiment and to the marriage.

She explains that while she moved out of the house, she is still dedicated to making things work. The next episode suggests that Nick might not be alone at the house anymore.

The episode 12 promo sees the two do their "pillow talk," which Nick believes will help their relationship to mature and grow.

The question was about how they believe will make a house a home. Nick answered, "To have a home that we could call our own and we could start a family."

Sonia kept it short and sweet and answered that it is just about being happy. "I think we're on the same page," Nick can be heard saying in the background.

It looks like things will look up for Nick and Sonia come "Married at First Sight" season 4, episode 12. The tricky part now is to continue this progress.

In addition to that, the two, like their fellow season 4 couple Tom and Lillian, will have to meet their in-laws, which will be a whole new challenge for them.

It was already difficult for Nick and Sonia to keep things in control as a pair. Adding the parents to the equation will certainly change the ball game, especially for the former, who has professed to be an introvert.

"Married at First Sight" season 4 episode 12, "In-Laws," will air on Tuesday, Oct. 11, at 8:30 p.m. ET on FYI.
