Love Is Blind typically brings the couple's families into play around the middle of the season, and there are times they cause even more drama to an already unstable situation. Since Love Is Blind season 1, the families of the participants come into play once the couples are already engaged and living together. The pod phase of the experiment and the honeymoon vacation is meant to be isolated and away from family and friends. However, once the couples return to their normal lives and try living together, their families are introduced if they agree to be part of the production.
