Tune in for the next episode of "Pretty Little Liars" to see how the girls are healing from their devastating captivity in Charles' Lair.

"The girls may have gotten out of the Dollhouse but what happened to them during their time of captivity has lasting effects," the show's synopsis reads on a YouTube promo. "With worried loved ones watching over them, the PLLs are home and trying to heal, with not much success. Even with suspected tormentor Andrew in custody, Aria, Emily, Hanna and Spencer fear they are far from safe. Meanwhile, Alison must deal with her past indiscretions and her notoriety around Rosewood."

In the season premiere, the girls finally escaped the dollhouse and are trying to figure out how Charles is related to Alison's family. They figured that Charles is A in Season 5, and now the big mystery is to figure out who Charles is.

"PLL" star Sasha Pieterse talked to Zap2It ahead of the Season 6 premiere regarding Charles.

"She has no clue who this person is," Pieterse said. "And so, that also brings up if Charles is somehow related to the DiLaurentis family, how come no one knew about him?

"That unravels a whole other different but cool storyline actually because as much as everyone knows what's happened and the girls are trying to figure it out, they're also following their own storyline and their own demons."

Charles is especially obsessed with Alison in the series. Will this season reveal why he is so obsessed with her?

"Charles is obsessed with the girls and obsessed with everything that he has created in his mind. So, to have the real Alison is his obsession and his dream. ... [This summer] we'll find out how this has all come about as well as the history of Charles and the reason he is so obsessed," Pieterse said.
