'Pretty Little Liars,' Season 2, Episode 15, A Hot Piece of A: TV Recap. There is real movement, at last! The girls get Caleb to hack A’s phone—against Hanna’s wishes—but he only retrieves a picture of spooky dolls before A shuts it down. Hanna plans a surprise birthday party for Caleb at Spencer’s lake house. Emily’s added community service is at a crisis center, where she takes a call from the person who was in the greenhouse—Lucas! Lucas tries to kill Hanna on the lake as they row to the pier to set fireworks, but she knocks him overboard. In the end, we see A (probably) fishing out his sneaker. Is Lucas dead? Meanwhile it looks bad for Ezria: Byron threatens to call the police; Aria’s grounded.
