Paige's past with Ali: As we see in this sneak peek, Paige (Lindsey Shaw) has a history with  Alison (Sasha Pieterse). According to the press release about the episode, Spencer (Troian Bellisario) will learn that Paige has a "violent past," and will uncover "new information about a blood feud between Alison and Paige right before Alison disappeared.”

Emily won't listen: The press release warns that Emily (Shay Mitchell) "is not ready to heed her friend’s warnings" when Spencer tells her about Paige's past. We see that in this sneak peek.

Spencer crosses a line: Worse, Spencer may "cross a line that Emily can’t forgive in her attempt to prove to Emily who Paige really is.”

NAT video unearthed: Meanwhile, this sneak peek reveals that Pastor Ted finds the thumb drive full of NAT videos that Spencer threw at Ian (Ryan Merriman) back in Season 1.

Ezria update. The good news is that Ezra (Ian Harding) will be in the episode, and it's his birthday! That bad news is that he and Aria (Lucy Hale) are still having problems after the Maggie reveal.
