Kristen's bizarre vacation behavior threatens to spoil the girls' trip to wine country, while Scheana breaks down over the fact that she's no longer close with Stassi and Katie. Back in LA, James is overjoyed when he gets a last-minute invite to the guys' wild "staycation," and Jax fears he may revert to his bad boy ways when Tom Sandoval invites girls back to their hotel room.
