Fans of 'Pretty Little Liars' had hoped that the Season 6 premiere would provide answers to their questions regarding the show, but none of these were fulfilled. On the contrary, the sixth season of the teen drama television series began with another bagful of questions.

According to IB Times, Season 6 of the 'Pretty Little Liars' picked up soon after the events of the Season 5 finale that showed the Liars shut in outside Charles' property. However, after enduring the troubles inflicted by Charles for about three weeks, the Liars were successful in their plan to torch the dollhouse and escape.

However, fans had another surprise in store for the in the final moments, as the police discovered a sixth girl in Charles' dollhouse. The sixth girl named Sara Harvey had gone missing the same time when Alison did. This suggests that Sara might have been in Charles' custody for almost two years.

In fact, the viewers as well as the Liars were first introduced to Sara in 'Pretty Little Liars' Season 4 episode titled 'Who's In The Box?' when the Liars went see a friend of Sara, believing that Sara could be the girl who was buried in Alison's grave.

However, they later discovered that the girl was Bethany Young.

As of now, it has not been revealed as to how Sara is related to Charles, and why did the latter keep her in captivity. Meanwhile, some fans are of the view that Sara and Charles may possibly be the same person.

In 'Pretty Little Liars' Season 6 episode 2 titled 'Songs of Innocence,' fans will see the Liars suffering from post traumatic stress disorder after coming out of Charles' prison. Still the girls are not convinced that Andrew is Charles, and even though he is behind bars, the girls fear that they are not yet safe.

The official synopsis of 'Songs of Innocence' released by the network reads, "The girls may have gotten out of the Dollhouse but what happened to them during their time of captivity has lasting effects. 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."

The synopsis further states that Alison will be forced to cope with her past imprudence as well as her "notoriety around Rosewood."

'Pretty Little Liars' Season 6 episode 2 titled 'Songs of Innocence' will air on Tuesday, June 9, on ABC Family.
