Guess Who's Arguing at Dinner?

As the ladies head out for a day of shopping in Cartegena, Bethenny continues to unravel, and the women's patience with her begins to run out. Carole approaches Sonja for insight on Bethenny, and later over dinner, Tinsley, Ramona, and Sonja try to not eavesdrop on a heated conversation between the two distant friends. Meanwhile, at the other end of the table, a comment Luann makes to Dorinda sends Dorinda off the deep end and puts their friendship on the rocks.
