Married at First Sight’s Lillian Vilchez in Finale Sneak Peek: ‘I’m So Worried’ That Husband Tom Wilson Wants a Divorce

The end of the road? Married at First Sight's two remaining couples face the final verdicts on their marriages in the Tuesday, October 25, season 4 finale, as seen in Us Weekly's exclusive sneak peek.

The FYI relationship series' preview clip shows Lillian Vilchez and Tom Wilson leaving their house in the morning ahead of Decision Day, where they'll both be forced to choose whether to stay in the marriage. The newlyweds shared sparks right out of the gate but struggled a bit with compatibility issues as the season wore on.

"Obviously this is a really big decision — it's not something to take lightly," Vilchez tells the camera. "We're promising each other to be there for everything — good and bad, thick and thin. I am so nervous. I don't even know what I am going to say. No idea."

"I don't know what he's thinking," the realtor continues. "And I'm nervous — I'm scared. I'm scared of hearing his answer. I don't even know if I want to hear his answer. I'm a wreck right now, and I'm so worried that Tom will choose divorce."

For his part, Wilson says to the camera, "I'm a little bit nervous about my decision today. I know I don't want to break Lily's heart, and I don't want to set such a high expectation either. Things could go either way."

Watch the tense clip above, which also shows Nick Pendergrast and Sonia Granados psyching themselves up for the moment of truth. 

Married at First Sight airs on FYI Tuesdays at 8:30 p.m. ET.
