Tensions run high at Mauricio's party in Mexico, as Kyle demands to know exactly what Lisa Rinna said about her sister, Kim; Erika advises Lisa Rinna to come clean with Kyle; the Mexico trip wraps up with a wild boat ride and a dance to remember.

Erika flexes her acting muscles as she rehearses for her upcoming soap role with Eileen. Lisa Vanderpump and Ken visit their new dog rescue center. Later, Kyle throws a cake tasting for Wilson Phillips singer Carnie Wilson, where Lisa Rinna makes a startling — and very public — confession to Kim.
