Some secrets the girls are holding onto should be shared, while others are best kept hidden - no matter what the cost. The truth can sometimes hurt and the girls must take that into account when deciding to reveal secrets. Visiting Mona is driving a wedge between Hanna and Caleb. But would it be so bad if Hanna told Caleb that her visits were because she needed to see Mona to get information about this new A? Aria, on the other hand, is dreading telling her mom, Ella, that her dad, Byron, is back in the dating scene and dating Meredith (recurring guest star AMANDA SCHULL – One Tree Hill, Sorority Wars, Center Stage). But wouldn't it be better if Ella found out from Aria than hearing it someplace else? And Spencer needs to know the truth about Melissa (recurring guest star TORREY DeVITTO – The Vampire Diaries, One Tree Hill), even if the truth hurts. Meanwhile, Emily finds some solace after meeting Maya's cousin, Nathan (recurring guest star STERLING SULIEMAN – The Vampire Diaries).
