Five years later, and the Pretty Little Liars are dancing to the same old tune.

'Pretty Little Liars' Season 6: Bottoms Up! The Liars Will Have A New Way To Unwind In 6B

Rosewood is Pennsylvania's murder hot spot once more, and this time, Uber A is pulling the strings. Someone killed Charlotte (Vanessa Ray), and Big A's death will send the Liars tumbling back down the rabbit hole. Series creator Marlene King isn't ready reveal the new baddie's identity to the world just yet, but she did dish out a few teasers in the wake of the season 6B premiere.

"Along with the new mystery in 6B is the birth of what I call our 'Uber Bad' in the show," King told TV Line. "Who is this 'Uber Bad'? We find out fairly soon what this 'Uber Bad' wants, but we won't know who it is for a while."

Could one of the Liars have killed Ali's sister? Hanna (Ashley Benson), Aria (Lucy Hale), Emily (Shay Mitchell), and Spencer (Troian Bellisario) weren't too keen about Charlotte's release back into society, but would they really choose to solve the problem with homicide? According to King, no one should be ruled out.

"Everyone is a suspect," King explained.

While it is clear the Rosewood PD is labeling the Liars as prime suspects, the real killer could be someone from their post-A lives.

"Given the girls' history with newcomers, it's fair to say that they should be cautious," King warned.
