The Party Favor

With Senior Prom in full swing, the good side, as well as the bad, comes out in everyone. Taylor hits an all-time high in her life, while Summer hits bottom with her prom date. Seth, with the help of Anna, devises a plan to win Summer back. Meanwhile, Volchok escorts Marissa to prom, and Ryan brings an unexpected girl from the past. Later, one of the girls is crowned Prom Queen, but the event is overshadowed when Ryan lapses back into his own ways when the Prom funds go missing.
