In the Season 3 premiere, Lisa Vanderpump still rules over everything at SUR, but no longer rules over Stassi, who returns from New York to find everything has changed between her and her former friends. Meanwhile, Jax prepares for plastic surgery, Scheana plans her perfect birthday party, and Tom Sandoval sparks a romance with Ariana, but all happiness is jeopardized when Kristen digs up a secret that will rock everyone.

After going over the budget and past schedule, Lisa struggles to make the grand opening of PUMP a huge success. Stassi confronts Scheana over her mean-spirited tweets, but Scheana maintains she only retweeted what someone else already said. Kristen seeks closure with Tom Sandoval, but watching Ariana take her place triggers her innermost feelings for her ex-boyfriend.
