The next episode of "Married at First Sight" season 3, titled "Celebrations," will prove that Tres and Vanessa's relationship is going stronger and more passionate, but their marriage will be challenged.

The synopsis for the episode teases that Vanessa will feel insecure about learing of Tres's friendship with another woman. It is unclear how she will deal with this but with the positive direction their marriage has been going, fans of the couple will not have anything to worry about.

Out of all three couples, Tres and Vanessa are the ones that are actually making great progress in their marriage. In a family gathering the couple attends in the next "Married at First Sight" season 3 installment, Vanessa will get a piece of advice on how to keep the marriage alive.

In a promo for the episode, Vanessa is asked by a family member for marriage advice, which she found quite tough to answer since she has only been married for less than a month. She, in turn, gets a piece of advice. Another family member recommended that "a lot of sex, a lot of love" should fuel up the marriage. This made Vanessa let out a squeal. Tres, who was hanging out with the guys, overheard this and said that the advice "sounds good."

In the previous "Married at First Sight" season 3 episodes, Tres and Vanessa actually already thought about starting a family. This advice should give them a head start on their plans for their future as a married couple.

Meanwhile, the new "Married at First Sight" season 3 episode will also see Sam hanging out with Neil's friends as a way to get to know more about her husband. A separate promo also sees Neil spending some time with his wife in her favorite spot – the sky gym.

Things between Sam and Neil haven't gone so well lately, but it is exciting to see the pair still making an effort to get the marriage going despite their differences. It remains to be seen if this will help them spark some real romance.

David and Ashley's marriage, meanwhile, is going downhill. In this "Married at First Sight" season 3 episode, Ashley will confront her husband about texting another woman.

"Married at First Sight" season 3 episode 10 "Celebrations" airs Feb. 2 at 9 p.m. ET on FYI.
