The girls are at the Brew, discussing the Black Widow and where Spencer's sister was the night the Lodge burned down. Emily and Hanna agree that Melissa could be the mystery woman while Spencer is using french fries and carrot sticks to map out the geography of the area to see if it is even possible for the person who arrived in the plane could have gotten to the lodge in time to save Aria, Hanna and Emily from the fire. Hanna and Aria argue about Ali possibly being alive and rescuing them from the fire. Hanna states that they never saw a body at the funeral. Aria thinks it is crazy to believe their dead friend could be alive. Spencer is undecided if it could have been Ali that she saw coming out of the plane. Mona comes into the Brew and says that she has been thinking a lot about the Ali thing. Hanna accuses Mona of putting her mom’s phone in Wilden’s coffin. Mona says she didn't do it and will do anything to prove that they are all in this together, so Spencer says to take them to the lair. Mona readily agrees. The presence of Mrs. DiLaurentis in Rosewood continues to unnerve all those around her, especially when she gives Hanna a family parrot, whose gift for mimicry provides startling insight into Alison's last days. Tired of feeling defenseless against "A," Aria decides to learn self-defense and is intrigued by her sexy instructor. Meanwhile, Toby shares a heartbreaking secret with Spencer, and Hanna makes an alarming discovery regarding her mom. To complicate matters even further, "A" nearly kills the newest Liar, Mona, and makes a drastic move which leads to potentially devastating circumstances for Emily. #PLL #PrettyLittleLiars
