There are only a few more episodes before Charles' true identity is revealed in ABC Family's "Pretty Little Liars."
But as the Liars gather more evidence to prove Charles has been their tormentor all along, Alison is expected to have a change of heart regarding her elder brother. The next episode entitled "FrAmed" will see Alison having trouble believing the Charles she remembers from her childhood could be a murderer as well.
"The more Alison learns about her brother the harder she finds it to connect a deranged murderer to the young blond haired boy she sees in the photos and in her memories," the synopsis read.
In the meantime, their recent run-in with Charles will result in the Liars being banned from attending their prom due to security reasons. But their moms will decide to throw a party for the girls in Spencer's barn, and this could result in another set of problems.
"After their latest run-in with Charles, tensions are at an all-time high with the PLLs and the town of Rosewood. Aria's big moment of seeing her work displayed in an art gallery is in jeopardy as Ella is determined to keep her safe at home. Hanna is still uncomfortable with the unexpected scholarship money and is determined to give it back, even if that means ruining her chances at going to her school of choice," the synopsis added.
As for Charles' identity, there are a number of fan theories out there that points to Wren being the main suspect. According to a "Pretty Little Liars" insider, Wren is the villain and fans can expect him to reveal himself to Alison during their prom night.
However, the final reveal will take place only in the midseason finale entitled "Game Over, Charles."
"Pretty Little Liars" airs Tuesdays on ABC Family.
