The Season 6 finale of "Pretty Little Liars" is the beginning of the end of yet another mystery involving Charlotte. It has been heavily teased that the new villain will finally be unmasked at the end of the episode titled "Hush, Hush, Sweet Liars."
The midseason premiere saw the Liars coming back to Rosewood to testify whether Charlotte could be released back into society. But things went terribly wrong shortly after their return home. Charlotte was murdered and the Liars found themselves being threatened by a new villain, dubbed Uber A, who wanted the Liars to find Charlotte's murderer, or else face the consequences.
The identity of the villain is still a mystery. Fans of the show have come up with various theories on who Uber A could be, with everyone from Sara Harvey to Dr Rollins finding a place on the suspect list. Executive producer Marlene King recently tweeted that a twin will be introduced in the finale, and this sparked speculation that the twin could be Uber A. King also hinted at the villain being related to someone fans have seen on the show.
The official synopsis does not give any hints about Uber A, but it does say that Aria-Ezra, Hanna-Caleb and Spencer-Toby will work together to sort out the new problem the girls have landed in.
"With the stalker threatening to kill all of them if they don't divulge Charlotte's killer by the election, the PLLs and company, at wit's end, must boldly fight back," the synopsis reads.
Elsewhere, Ezra and Aria will work together on is book and old feelings start to come to the surface as he finishes the last chapter. Another couple who will explore "what could have been" is Caleb and Hanna.
"Meanwhile, Alison experiences strange visions and starts to question her sanity; Emily keeps tabs on her to make sure she's okay," the synopsis reads.
