Ted Mercer (Emma's new dad while she's pretending to be Sutton) invites Emma to the annual father-daughter dance at the Country Club, and Emma is terrified because she possesses no ballroom dancing skills whatsoever - unlike Sutton. Ethan works at the club and gives Emma dance lessons in order to help prepare her for the big night. Meanwhile they attempt to figure out where Sutton disappeared to in LA and also who broke into her bedroom and stole her laptop.
Alex Rybak, Mads' father and Sutton's god father, grills Emma to see if she's had any contact with his son, Thayer (Mads' older brother), who recently moved to LA. Speaking of brothers, Ethan's older brother (the cop) catches Ethan using his work computer at the police station to see if anyone matching Sutton's description has been arrested or admitted to a hospital in LA. Dan warns Ethan to stay away from Sutton, that she is nothing but trouble.
After several days of dance lessons, dress shopping, and learning how to impersonate Sutton, the big day is finally upon Emma, who is extremely nervous that everyone will figure out she is a fraud when they realize she can't dance. But Emma is able to pull it off without too many missteps.
Later, Sutton finally contacts Emma and Ethan. She tells them that the trail in LA has run a little cold, but that she'll call them shortly once she has new info regarding the whereabouts of their biological mother.
