When "Married at First Sight" season 4 returns to the small screen, Nick and Sonia will start to seriously think about their future together and determine what's best for them.
In episode 11 titled "To Love and to Cherish," the pair will ask themselves what they want as individuals and as a married couple.
In a clip teasing the upcoming "Married at First Sight" season 4 installment, Sonia admits that she has no idea if there will be a future with her husband.
Nick seems to feel the same way, explaining to a friend that the relationship has gone "from one end of extreme to the other" over the course of the experiment.
At some point in the "Married at First Sight" season 4 episode 11 clip, Sonia confronted Nick about the time he lied about sleeping with her multiple times.
"I don't think you fully understood how much you hurt me," she tells him. Nick apologized, although he was not looking at Sonia at all while he did.
It is unclear if he is still willing to go through the marriage as he expressed several times now that he is not into Sonia at all.
He even denied sharing nights of passion with his wife when he was asked about it by Pastor Calvin Robertson in the previous episode of "Married at First Sight" season 4. That being said, things are not looking good for them.
As for Lillian and Tom, they appear to be having issues with the former being too consumed with work that she no longer has time for her husband.
Tom admits in a "Married at First Sight" season 4 episode 11 clip that while he thinks it is "great," he wants to make it a point that they still spend time together.
Upon arriving late, Lillian told Tom that "I wanted my vows to be ready for you today ... I didn't have time," to which Tom replied to remind his wife that "This is not just an experiment anymore, this is marriage."
It looks like things are getting serious between the two as the problems they have just prove that they are already a full-on married couple rather than two strangers working to be one.
"Married at First Sight" season 4 episode 11, "To Love and to Cherish," airs on Tuesday, Oct. 4, on FYI.
