At odds with her friends over Paige (recurring guest star LINDSEY SHAW), Emily doesn't know where to turn when the media attention becomes too much for her. "A" sees this as a perfect opportunity and takes advantage of the situation and sends Aria, Emily, Hanna and Spencer on a path to a possible truce.

Emily's relationship with Paige (recurring guest star LINDSEY SHAW) has been anything but easy, but she finally feels like things are now going in the right direction. So when Spencer comes to her with a sordid tale about Paige's history with Alison, Emily is not ready to heed her friend's warnings. Now that Spencer knows Paige's violent past, however, and this new information she's learned about a blood feud between Alison and Paige right before Alison disappeared, Spencer can't stand by to let one of her best friends get close to a potential enemy. Will Spencer cross a line in her attempt to prove to Emily what kind of a person Paige really is? Meanwhile, Aria feels she has to help Ezra move on from his past if their relationship is to move forward, but what she finds may be more than she expected.
