More drama is expected from this week's episode of "Married at First Sight" as three couples, who recently got married without knowing anything about each other first, continue to work out their differences and make their marriage work.

This Tuesday, Tom Wilson will muster the courage to reveal to his wife, Lillian Vilchez that he actually lives in a bus, according to the synopsis from TVGuide. Although Wilson and Vilchez started off pretty great after their wedding, being the couple who consummated their marriage during honeymoon, things turned sour following an argument about being materialistic.

Wilson was also supposed to tell Vilchez his big secret last week but this has been put on hold for the next episode. In an exclusive interview with The Knot News, Vilchez gave her opinion about Wilson living in a tour bus.

"I am going to say I would have never imagined my husband lived on a bus," the 24-year-old realtor said in the interview. "I always assumed he lived in an apartment like myself, and then we go visit each other's places and we drive into a trailer park and pull up to an RV!" she continued.

Despite the revelation, Vilchez will remain optimistic about being paired with the 28-year-old yacht interior specialist. "Tom and I do have different lifestyles but are still very alike," she said.

As for Sonia Granados and Nick Pendergrast, who admitted that they like each other, a real challenge will be up this week as the former needs to face her fear of dogs, because the latter, apparently, owns two.

Heather Seidel and Derek Schwartz, on the other hand, are the ones who need saving this week. Seidel is concerned about her husband's vices and while Schwartz seems to be happy with his wife, he's upset that she's not willing to consummate the marriage yet. The two seem to constantly argue about each other's personality and things start to get sour despite a smooth wedding ceremony. However, they will work their issues out by seeking help from a pastor.

"Married at First Sight" season 4 airs Tuesdays at 8:30 p.m. EDT on FYI.
