The ladies head to the Berkshires to celebrate Dorinda’s 50th birthday and are impressed with Dorinda’s luxurious estate. In the evening, Kristen mentions to Ramona and Dorinda that John was too touchy with her at World Bar, setting Dorinda off. During dinner at a local inn, the women discuss Bethenny’s very rough childhood and the walls she has up, but Heather isn't feeling very sympathetic. On the night of Dorinda’s big 50th birthday dinner, all of the boyfriends and husbands descend upon the house and one surprise guest arrives just in time--Bethenny. When Bethenny reveals she doesn’t eat fish, Heather takes it upon herself to fix the situation, which doesn’t end well for either woman.
