Mr. & Mrs. Schwartz, Take Two

S8 E15: The group travels to Las Vegas to celebrate Schwartz and Katie's second wedding, but leave a heartbroken Kristen behind. Lisa shows off the Vanderpump Cocktail Garden, Beau calls Stassi's father to ask permission to propose, Schwartz finds a bra in his bag that doesn't belong to Katie, and Max sets his sights on a cocktail waitress who looks eerily similar to Scheana. Meanwhile, back in Los Angeles, Dayna and Brett grow closer during a double date with James and Raquel.
