시즌 1, 에피소드 21: Rosewood's Founders Festival sets the stage for more secrets. Everyone has something to hide - whether it is a secret romance, or revealing a true identity and true intentions. For Aria, Emily, Hanna and Spencer, keeping things hidden is second nature, but having to live with those secrets can become a big burden. How long can Aria be with someone when they can't go out in public? Is it a true friendship when Spencer and Toby aren't able to be seen together? How truthful can Emily be when she can't be honest about whom she wants to be with? And how can Hanna move on when secretly she wants to be with the one who broke her heart? With someone like "A" out there to watch their every move, the four girls may not have to worry about keeping things hidden for too much longer.
