12. Now You See Me, Now You Don't

The Liars receive a package containing four Magic 8-balls bearing their names, with a message that if Ashley goes free, "A" will come after them. Ashley goes free from jail after Travis convinced the police she didn't do it. Meanwhile, Aria gets closer with Ezra after a meeting. The Liars receive another package containing a child-sized coffin which contains a doll resembling Mona, followed by a text that "A" will hurt Mona and set the Liars up. The Liars later receive one last package, containing a saw with a threatening message written on it, saying a girl will disappear.

After some quick research, the girls decide that A is leading them to a magic show in nearby Ravenswood. When they arrive, Aria is chosen to be a volunteer for a magic trick. When Hanna and Spencer are distracted by this trick, A kidnaps Emily. The Liars follow Red Coat and discover that Emily is trapped in a coffin that is heading straight for a giant saw. While the Liars seem to be unable to open the coffin in time, Red Coat stops the saw and saves Emily. The girls then notice that there are two Red Coats.

Spencer chases the one that saved Emily outside, while Aria gets into fisticuffs with the other who is wearing an Alison mask. Aria hits Red Coat in the face, knocking off her mask and revealing CeCe Drake. CeCe gets knocked off from the platform, where CeCe and Aria have been fighting on. She lies motionless, presumably dead, but when the Liars reach the spot where she fell, she has disappeared. Spencer leads the girls to a lair she believes is "A's", where she had been led by the second Red Coat.

She believes it was Alison, because she is helping the girls. Toby finds out Melissa brought Wren with her to London. He follows Shana, while she meets Mona at a hotel and delivers some information. The girls do some digging, and find evidence that suggest that the owner of the lair is a man. When the girls find out that the lair owner, whom they still believe is "A", has also been following Ali, and thinks she will be at a Ravenswood Celebration taking place that night, the Liars decide that they should go find her before "A" does.

On their way, the Liars are stopped by Mrs. Grunwald who reveals that Ali is alive, and Mrs. Grunwald saved her life. Someone was after Ali, and Ali was phoning Mrs. Grunwald, asking her to help her find out who it was. On the night Ali 'died', Mrs. Grunwald had sensed Ali was in trouble and rescued her by pulling her up out of the soil where she had been buried alive. Ali was injured and in shock, so Mrs. Grunwald brought her to the hospital, where Ali disappeared when Grunwald went inside.

Grunwald tells the Liars to get out of Ravenswood as soon as possible because "he" is watching them and he hopes that the Liars will bring him to Alison. Caleb gets on the bus for Ravenswood to hack into the computers in A's lair, and the Liars decide that they should go to the memorial party no matter what. A man is shown watching the girls, and he walks into the lair exposing his identity: Ezra Fitz. ' A' ending: "A" dresses up as a World War I era soldier as creepy music plays.
