View this post on Instagram Instagram PostTonight on Married at First Sight, the couples met their friends and also threw housewarming parties for their loved ones. Miguel told his friend Steve that Lindy was a great wife but was unsure if she would fit into his friend's group. However, he stated he liked that Lindy was kind, agreeable, open-minded, and liked to travel. Steve noticed Miguel's puppy eyes while talking about his wife. Krysten also discussed her wedding issues with her friend Joanna. She said there was a difference between their domestic life choices. She was afraid that they might fight about the same in the future.Krysten then revealed that the couple had their first big fight over the housewarming party theme. While Krysten wanted a French-themed party with wine, Mitch wanted themes like communist regimes, alien invasions, etc. The couple ultimately decided on the theme of retro-futurism.The episode description reads,"Five newlywed couples settle into their lives in San Diego and prep to be reunited with friends and family for the first time since their weddings; they plan their first housewarming parties together; grievances are aired and advice is shared."Alexis and Justin fought again over the dogs. Justin hid the fact that Newton had not eaten for the past two days, and Alexis only came to know the truth after Newton started bleeding. She fought him over being secretive and walked out of the room. She later made up with him and threw a housewarming party. It will be interesting to see how the couple sorts out their pet-related issues. Married at First Sight airs on Lifetime every Wednesday at 8 pm ET.
