FYI's "Married at First Sight" Season 4 is almost coming to an end. Out of the three couples in this season, one pair had given up with each other and had not made it to the final stage of the show. Two couples made it to the final, however, their fate has not yet been known.

On Tuesday, the final episode for the reality television series will air and it will reveal the couples' decision on their marriage.

Sonia Granados and Nick Pendergrast, together with Lillian Vilchez and Tom Wilson, made it to the final stage and will face the relationship experts to discuss whether or not they want to pursue their marriage.

One couple had already parted ways, Heather Seidel and Derek Schwartz, but rumor has it that another remaining couple will follow their footsteps.

According to Us Weekly, Lillian and Tom are now in doubts on going further with their marriage. The 24-year-old realtor is reportedly worried that Tom would choose to divorce her as they had been having arguments about compatibility issues at the earlier parts of the show.

Movie News Guide has also reported that the 29-year-old boat interior designer stated that it would not be his intention to hurt Lillian, but he does not want her to have high expectations from him, as things could go either way on the show.

A source also revealed that Sonia and Nick have a better chance of staying married than Lillian and Tom. It has been reported that the couple realized that they have the same plans for the future, as Nick saying that they can do whatever they want, wherever they want, as a couple.

It can be recalled that the couple lacked chemistry when they first saw each other on the reality series, but surprisingly, they could end up as a strong couple for the final episode of the series, entitled 'Till Death Do Us Part.'

Fans are excited to know the revelations in the finale of the fourth season of the reality television series. 

"Married at First Sight" Season 4 final episode airs on Tuesday, Oct. 25 on FYI.
