With one wedding down and four to go, our soon-to-be spouses anxiously prepare to say "I do" to a stranger. However, when one groom gets terrible news, a wedding has to be postponed for the first time in Married at First Sight history. And one father of the bride could ruin his daughter's special day.

In the morning, each is bombarded with personal questions from their spouse's friends and family. Then it's time for sun in the fun as they jet off to a honeymoon in Mexico.
