Troian Bellisario and Ashley Benson keep their own little secrets in this new still from Pretty Little Liars.

In tonight’s episode “Single Fright Female,” Emily’s (Shay Mitchell) relationship with Paige (Lindsey Shaw) has been anything but easy, but she finally feels like their relationship is going in the right direction. So when Spencer comes to her with a sordid tale about Paige’s history with Alison (Sasha Pieterse), Emily is not ready to heed her friend’s warnings.

With Spencer (Bellisario) knowing Paige’s violent past and this new information about a blood feud between Alison and Paige right before Alison disappeared, she can’t stand by to let one of her best friends get close to a potential enemy. But will Spencer cross a line that Emily can’t forgive in her attempt to prove to Emily who Paige really is?

Meanwhile, Aria (Lucy Hale) feels she has to help Ezra (Ian Harding) move on from his past if their relationship is to move forward, but what she finds may be more than she expected.

“Single Fright Female” airs TONIGHT @ 8PM ET/PT on ABC Family. 10+ pics inside…
