Spencer encourages Toby to tell the girls why he gave the lair to "A," but Toby says that if she tells the girls about his mom, "A" won’t give him any more information and he'll never know what really happened to her. He says that he talked to Eddie Lamb at Radley, and he didn’t mention Ali, but is definitely hiding something. He tried talking to his dad too, but it didn’t go well. Spencer can't sit around and do nothing so she picks up the phone and calls Gamma Zeta Chi, the sorority at Cicero College, to ask about the hidden room. Hanna has some explaining to do to her parents and the police after she's found with something she shouldn't have. Mona spills a secret of Spencer's to the other Liars leading to hurt feelings amongst the group. Emily tries to help Hanna, only to have "A" turn the tables. Aria helps out a friend of her brother Mike's, who gets the wrong impression of her. Meanwhile, Shana keeps popping up in the most unusual places, and Spencer's investigation into who was on the other end of Ali's mysterious phone number leads her and Toby to the town of Ravenswood — which is unlike any place they've ever seen. #PLL #PrettyLittleLiars
