Now You See Me, Now You Don't
In the shocking summer finale, an intriguing riddle from "A" has the Liars hitting the road and heading to Ravenswood, where they are surrounded by some familiar faces. During a very special magic show, one Liar pulls a disappearing act, leaving the other three scrambling to make sure she hasn't succumbed to the tricks of "A." But before they can hightail it out of Ravenswood, they make a shocking discovery that proves everything they thought they knew about "A" and the "A" team might be wrong. With this discovery, the Liars may just have started "World War A." Meanwhile, a joyous reunion between Hanna and her mother is cut short when "A" sets sights on a new target. And Toby (recurring guest star Keegan Allen) uncovers some surprising information about Wren (recurring guest star Julian Morris).
