A shocking split awaits the "Married at First Sight" season 4. 

While the start of a new marriage is expected to be full of joy, the current situations of the couples in the series are too distressing to handle.

According to reports, a divorce is set to happen between Heather and Derek after the former got offended by the latter. Derek reportedly flirted with another woman during their honeymoon, hurting Heather.

Aside from Heather and Derek, Tom and Lillian are also rumored to go through some challenges in their relationship. The couple does not have any issues with fidelity, but they have some serious issues when it comes to raising a family. While one of them is already excited to start their own family, the other is not ready yet. It remains unknown who is who, but fans already have an idea whose side is which.

Viewers speculate that Tom could be the one who is ready to raise a family of their own, while Lillian is the one who isn't ready yet. This theory is supported by the fact that Tom was willing to sacrifice something big for Lillian--to move out of his beloved bus, his home--when they got married. On the other hand, Lillian is the happy-go-lucky type who seems not to be ready yet for such a huge responsibility as starting a family.

There are speculations that until Tom and Lillian finally arrive at a compromise when it comes to their goals, their relationship will remain on the rocks.
