Aria, Emily, and Spencer are leaving school. Aria tells them about her mom considering the trip to Austria and how she can't even imagine her mom being a continent away. Spencer tells them she couldn't find any information about the number Tippi gave them, but she's not giving up. Emily says she started going through Ali's notebooks and asks the other girls if they want to come over tonight and search them together. Spencer says she can't because she promised Toby she would help him with something.
Emily's mom come up to them outside of school and tells Emily she's giving her a ride home. She is angry because the doctor called and asked if Emily has been taking her mom's medication. Emily denies it, but Pam says she checked the bottle and can see pills are missing. When Emily tries to walk away, Pam grabs her arm and starts yelling, making a scence, so Emily gets in the car and leaves. Aria then gets a text from "A" saying "Cleaning up Rosewood, one mean mommy at a time. Dig we must. Kisses - A," and wonders what "A" is planning for her mom.
Hanna worries that her mother is keeping a dangerous secret and is determined to protect her at all costs, which leads to an uncomfortable meeting with Detective Holbrook. A clue in Ali's things leads the Liars to a creepy mask maker, who takes a shine to Emily and may have ties to another Rosewood resident. Spencer and Toby continue their search into a painful chapter of Toby's past and Melissa returns to Rosewood. Meanwhile, after "A" targets Emily's mom, Pam, Aria makes a desperate plea of her mom, Ella. #PLL #PrettyLittleLiars
