With “Pretty Little Liars” winding down to its final episodes it’s time to start revealing the answers to some highly anticipated questions, and while the latest spoiler doesn’t give fans of the Freeform series a direct answer, it points them in a specific direction.

In new photos of Season 7, episode 19, obtained by E! News, the Liars seemed to have discovered a new suspect who could be A.D. and have some questions for her.

In the previous episode, Liar’s Lament went missing and Caleb (Tyler Blackburn) was working on tracking it down. When he finally received a signal from the game, he began to track it and asked Ezra (Ian Harding) to accompany him on his mission.

The signal led the men to Mona’s (Janel Parrish) apartment where she has a whole set up based on the Liars and the Archer Dunhill (Huw Elliott) murder case.

In one of the exclusive photos from “Farewell My Lovely,” Caleb, Ezra, Emily (Shay Mitchell), Spencer (Troian Bellisario), Alison (Sasha Pieterse), Aria (Lucy Hale) and Hanna (Ashley Benson) can all be seen glaring at a female sitting on the couch.

Although the female’s full face is not shown, it looks like it is Mona who is seated on the furniture with her hair in pigtails and wearing glasses.

In another photo, Spencer can be seen kneeling down attempting to get at eye level and speak with the woman. Meanwhile, the others characters look uneasy and concerned about what is going on. Why did Mona steal Liar’s Lament?

Could she be working for A.D. or is she the villain? In the promo for “Pretty Little Liars” Season 7, episode 19, Mona can be heard complaining that someone is always stealing the game away from her. Could Mona have taken matters into her own hands and decided to become the ultimate villain? Or maybe stealing Liar’s Lament was her way of being in control of the game again?

The new photos from the Freeform series also hint that Mona could have murdered Charlotte (Vanessa Ray). In the beginning of Season 7, Charlotte was thrown from the bell tower at the church and it was never revealed who killed her.

In one of the photos, Mona can be seen standing in the bell tower holding a small bouquet of purple roses. In the promo for the episode 19, “Farewell My Lovely,” Charlotte can be seen in the bell tower asking someone one if she is supposed to be afraid of them. Later on, she is seen laying in the grass surrounded by purple roses.

Did Mona reach her breaking point with Charlotte? What could Spencer be asking her as the group stands back and watches?

The narrator in the promo stated that Charlotte’s killer will be revealed in the next episode. With tensions flying high and a murderer on the loose, there are only two more episodes left before viewers will learn how it all ends.

“Pretty Little Liars” Season 7, episode 19, airs Tuesday at 8 p.m. EDT on Freeform.
