S3, E8: Emily is struggling to deal not only with the loss of Maya (guest star BIANCA LAWSON), but the knowledge that someone drugged her "that night" and how it has now affected Paige (recurring guest star LINDSEY SHAW). Going to make amends with Paige and try to explain the drugged flask ends up leading Emily to more insight of what she did "that night." Also, in trying to help Emily out, Spencer turns to Caleb to help crack into a website that might hold answers for them all. Meanwhile, Aria realizes she knows very little about Ezra after meeting his mother and Hanna makes a plea on Mona's behalf.
