Anthony gets an invite to the poly potluck through one of the poly groups he's a member of and convinces Lindsey and Vanessa to check it out, so the Triad heads down to San Diego.
Anthony's parents are selling their childhood home so the Triad takes a trip up north to visit the home one last time and take this opportunity for Lindsey to come out to her mom about being polyamorous.
Jen's monogamous sister drops by to check out Jen's new digs while Kamala has her hot date with Roxanne and hesitantly inquires about the true level of attraction between Roxanne and Michael.
Anthony encourages his wife Lindsey to find a local boyfriend so Lindsey thinks about reconnecting with an ex-lover Jacob, but is he polyamorous? Vanessa plans to propose to Lindsey and Anthony and ask for a life commitment and see what her true place is in the triad.
Lindsey and Anthony are legally married to each other and are both in a relationship with Vanessa.
These three are a primary relationship and refer to themselves as "the Triad". The pod of Kamala, Michael, Jen and Tahl is back with another new family.
