Charles will make sure to not miss the girls' little home prom in the upcoming episode of ABC's teen drama/mystery/thriller series "Pretty Little Liars."

In "Last Dance," Cartermatt reports that the deranged DiLaurentis has plans up his sleeve in order to make the occasion a night they will never forget. Spencer (Troian Bellisario), Emily (Shay Mitchell), Hanna (Ashley Benson), and Aria (Lucy Hale) are prohibited from attending the prom at Rosewood High due to security reasons. Not wanting their daughters to miss that momentous event in their high school life, the mothers decide to set up a makeshift mini prom in Spencer's barn.

After expressing their qualms about the plan, the girls give in gracefully, trying to make the best out of the situation. Ella (Holly Marie Combs), Pam (Nia Peeples), Veronica (Lesley Fera), and Ashley (Laura Leighton) will also use the time to catch up on everything that has transpired between their daughters and whoever "A" is.

Meanwhile, Realty Today reveals that at the season finale, the girls will finally meet Charles face to face. After years of torment, they will learn the whole story on how and why he became 'A.' Afterwards, season 6 will return with a five-year time jump.

Last episode, Aria's exhibit became the center of the police's investigation. Instead of her own collection of photographs, the visitors were greeted by images of the girls taken in the dollhouse. In the portraits, they were arranged to look like they were already dead. The photos were accompanied by an unsettling message, which Lt. Tanner (Roma Maffia) translated as "Stolen Dolls: They are not pretty." While the commotion was happening, Charles and Red Coat could be seen watching them through the surveillance cameras.  

After giving their statements to the police, the Liars decided to follow Rhys, the guy who offered Hanna a scholarship, and who looked eerily like Charles. The mysterious Carissimi Group employee ended up going to an abandoned doll factory and met with Aria's new photography friend Clark (Titus Makin Jr.).

At the end of the episode, viewers saw Charles and Red Coat preparing to kidnap the girls. Charles was placing a tuxedo and syringes in the trunk of the limo, while his accomplice handed him two prom invitations.

"Pretty Little Liars" airs Tuesday at 8 p.m. on ABC Family.
