Spencer is rattled when she sees Ali in a dream, but it leads her to discover Alison and "A" were sending each other messages in the classified ads of the old newspapers they found. So the Little Liars track down the address from the ad where "A" agreed to meet Alison. It's an old doll hospital, and the girls question the owner. She doesn't remember much, but a young boy seems to know a lot. He tells them about a couple that came to the shop, and they believe it was Melissa and Ian. Now convinced that Melissa is "A," Spencer tells her friends that Jason is her half-brother. Spencer shows Melissa the video from "A's" cell phone and asks her why she was in Alison's bedroom the night of her murder. Melissa denies being involved, and she threatens Spencer with her own knowledge.
Meanwhile, Aria discovers a filled-out application to a boarding school on her mom's desk. Aria confronts Ella and threatens to tell the dean about Byron's affair with his student if they continue to mettle in her life. Then Aria visits Ezra, who tells her he was fired.
To prove that Melissa is "A," the girls come up with a plan to have Mona kiss Caleb in front of Melissa. Immediately after, Hanna gets a text from "A," telling her about the kiss. The Little Liars return to the doll hospital to confirm their suspicion, but they are ambushed and quickly run away.
Also, Jenna takes off the bandage from her eye surgery and it appears she's still blind. Toby takes her to the Liars, and she apologizes, telling them she's not the one they need to fear. Jenna gives Toby page five of Ali's autopsy report, pretending not to know what it is. Later, Garrett is arrested. And Jenna, who everyone believes still can't see, manages to kill a fly with perfect aim. Hmmm...
