Pretty Little Liars

Pretty Little Liars Season 4, Episode 15: Four Liars and [SPOILER]! (PHOTOS)

Production on Pretty Little Liars Season 4 is going full steam ahead, with the cast and crew currently hard at work on Season 4, Episode 15. Recently, the cast filmed a scene featuring all four Liars, plus a certain "handsome teacher fellow."

We're very curious to know what brings all four Liars and Ezra together at the same time. Of course, it appears the cast was filming the Brew set, so it's possible Aria and Ezra run into each other there while the other girls are off in the different part of the store, but we're hoping these on-set pics will translate to an on-screen scene where Ezra interacts with all of the Liars at once. That would be an interesting dynamic!
