The senior prom brings out the best and the worst in everyone. When Taylor's prom funds are discovered to be missing, Ryan returns to his old ways, and prom night turns brutal.

On a windy, rainy night, Cappie is visited by a beautiful, mysterious girl named Destiny who turns out to be Patty the Fatty who loved Cappie obsessively since their days at camp. Over at the ZBZ house, Casey plans a slumber party to bond with the pledges but the night takes a drastic turn when Ashleigh reveals that a girl named Virginia hung herself in the house. Evan and Calvin, also braving the storm and lack of electricity, bond through the adventure of trying to kill the house rat.

An anonymous confession to the killing of a 16-year-old girl is found in a modern art exhibit. As a result, Rush and the team are forced to enter the complicated, emotional and vicious world of high school cheerleading in order to solve the murder.

Betty frantically tries to keep Daniel focused on work as he reverts to his old hard-partying ways, including romancing a multitude of stunning models. Things go from bad to worse when a tell-all writer (Emmy winner Leslie Jordan, "Will & Grace," "Boston Legal") in possession of Fey Sommer's diaries starts stalking the Meades. Another Suarez, Ignacio, feels the heat when Immigration caseworker Constance (guest star Octavia Spencer) pressures him to make their relationship a romantic one, and Wilhelmina and Alexis both try to get their hands on Fey’s diaries -- but for different reasons.

Betty, fed up with Daniel, Christina and Henry and how they've all disappointed her, does her best to avoid all three. Meanwhile, love's all around at Mode, as Alexis gets asked out on her first date as a woman; Amanda begins a flirtation with a designer (guest star Mykel Shannon Jenkins) who she assumes is gay; Wilhelmina struggles to deal with the tireless advances of her latest conquest, and Hilda gets a surprise from Santos (guest star Kevin Alejandro). Meanwhile, Daniel goes it alone in dealing with the aftermath of his one-time hook-up with Petra.
