If the latest spoilers for 'Pretty Little Liars' Season 6 episode 9 titled 'Last Dance' are any indication, Charles will ensure that he does not miss the girls' home prom in the upcoming episode of the teen drama mystery-thriller television series on ABC Family.

Quoting CaterMatt, Christian Today reports that in 'Last Dance,' viewers will see the crazy DiLaurentis plans to make the occasion a night that the Liars will never forget. Meanwhile, Spencer (Troian Bellisario), Emily (Shay Mitchell), Hanna (Ashley Benson), and Aria (Lucy Hale) have been prohibited from attending the prom at Rosewood High owing to security reasons. As their mothers do not want the Liars to miss that important event in their high school life, they decide to organize a temporary mini prom in Spencer's barn.

Initially the girls are somewhat skeptical about their mothers' plan, but they concede gracefully, with a view to take advantage of the situation. Ella (Holly Marie Combs), Pam (Nia Peeples), Veronica (Lesley Fera), and Ashley (Laura Leighton) will also be seen using the home prom to compensate for everything that has happened between their daughters and whoever "A" is.

In the meantime, a report in Realty Today claims that the girls will eventually come face to face with Charles in the 'Pretty Little Liars' Seson 6 mid-season finale. Following several years of suffering, the Liars will finally come to know the entire story regarding how and why he became 'A.' Later, Season 6 of the show will return with a five-year time jump, the report added.

In the previous episode titled 'FrAmed,' viewers saw Aria's exhibit turning out to be the center of the police's investigation. Instead of Aria's own collection of photographs, the visitors were greeted by photographs of the girls taken in the dollhouse. In the portraits, they were arranged in such a way that they looked like they were already dead. The photos were accompanied by a disturbing message, which Lt. Tanner (Roma Maffia) translated as "Stolen Dolls: They are not pretty." While the tumult occurred, viewers could see Charles and Red Coat watching them through the surveillance cameras. 

After the Liars recorded their statements with the police, they decided to follow Rhys, the person who offered Hanna a scholarship, and who appeared ominously like Charles. It was seen that this mysterious employee of Carissimi Group ended up going to a deserted doll factory and meeting Aria's new photography friend Clark (Titus Makin Jr.).

'FrAmed' ended with Charles and Red Coat preparing to abduct the girls. Charles was seen placing a tuxedo and syringes in the trunk of the limo, while his accomplice handed him two prom invitations.

'Pretty Little Liars' Season 6 episode 9 titled 'Last Dance' airs at 8 p.m. on Aug. 4, Tuesday, on ABC Family.
