In the video for “Chose or Lose,” Emily and Alison can be seen looking very much in love as they head to the bedroom for some quality time with each other. However, Alison’s smiling face quickly turns to one of worry upon entering the room.

Rather than a spacious and empty bed, Liar’s Lament is lying on top of Alison’s covers. Seeing the unhappy look on her face, Emily turns around and quickly begins to share Alison’s sentiments.

Caught off guard with the game’s placement, Emily asks Alison when she moved the game into the bedroom, but she reveals she’s not the one who has moved it. After taking a closer look at the gameboard, Emily discovers that a new puzzle piece has been added.

She then begins to worry because the relocation of the board means someone was in the house and could still be in there. However, before the two can plan the next move, a police siren can be heard coming from outside, which sends Emily racing out of the room to see what’s going on, marking the end of the sneak peek.

Although the Liars are unaware about how the new puzzle piece has arrived, the audience knows that Aria (Lucy Hale) is the one who added it to the gameboard. Although Aria has not had a turn with Liar’s Lament, A.D. gave her the task of betraying her friends once again in order to get back a police report she filled out against Ezra (Ian Harding) but never filed.

In the last episode, A.D. forced Aria to drop a phone at Spencer’s (Troian Bellisario), where its Bluetooth was used by the villain to play Peter (Nolan North) and Mary Drake’s (Andrea Parker) conversation about Jessica DiLaurentes’ (Andrea Parker) murder. As a reward for completing her task, Aria received a puzzle piece and the copy of the police report she never filed.

This is not the first time Aria has messed with Emily and Alison’s happiness. After Alison decided to follow through with the pregnancy because she was carrying Emily fertilized eggs which A.D. placed inside of her, Emily called up Spencer to help her set up the nursery.

After putting together an adorable room, Aria waited until everyone was gone and destroyed the nursery, while also splashing fake blood across the room. Did A.D. force Aria to relocate Liar’s Lament to Alison’s room or is she playing a new game?
