'Married at First Sight' season 4 spoilers news update: Tom and Lillian talk kids; Derek and Heather divorcing?

In last Tuesday's episode of "Married at First Sight," the newlyweds capped off their honeymoons and went home to settle into their new domestic situations.

Lillian Vilchez and Tom Wilson went back to Miami, where Lillian showed Tom her home. Tom was relieved that his wife is not the materialistic type. Also, while he received a warm welcome from Zeus, Lillian's dog, he initially stayed silent about the fact that he lives in a tour bus. When Lillian was invited into Tom's home, she was shocked but later admitted that the bus is beautiful.

However, the couple quickly realized that the tour bus doesn't have enough space for both of them and they soon began looking for homes. Lillian said that she wants to have children in about five years but Tom said that they could start having them sooner.

In a blog post written for People, Tom talked about sacrificing his tour bus for Lillian. "Moving out of the bus is definitely tough, but it's not like I'm selling it," he wrote. "I'm just giving this time for Lilly and I to get to know each other better."

"I'm excited to start this new stage in my life," he added and said: "I feel comfortable with Lilly at this point. We are going to try our best. The next couple weeks are either going to be awesome or it's gonna be extremely difficult. Only time will tell!"

Sonia Granados and Nick Pendergrast also went house hunting and found one that was a bit over their budget. Nick, who earns double of what Sonia makes as a social worker, insisted that they can make it work.

Apart from their financial differences, the biggest problem in the new couple's marriage is that Nick is very attached to his dogs while Sonia seems to be extremely dog-phobic. Will Nick's attachment to his furry friends lead to the couple's divorce?

Meanwhile, Heather Seidel and Derek Schwartz seem to be heading towards a separation. In the latest episode, the two ended up having to see Pastor Cal Roberson after Derek observed that Heather doesn't really want to stay married.

In "Married at First Sight" season 4 episode 7, titled "For Better or Worse," Heather and Derek decide if they want to split up, Sonia and Nick work on their communication skills, and Lillian and Tom clash over the topic of children.

"Married at First Sight" airs every Tuesday at 8:45 p.m. ET on FYI.
