It seems like the Liars are back where they all began after all the recent revelations.

In the previous episode of "Pretty Little Liars," they all discovered that Lesli (Elizabeth McLaughlin) also went to Radley Sanitarium, and the hooded figure was a woman. Does this mean that Lesli knew Charles? Was the dead older brother of Alison (Sasha Pieterse) and Jason (Drew Van Acker) just a decoy used by the real "A"? 

In the sixth episode of season 6 titled "No Stone Unturned," Aria (Lucy Hale), Spencer (Troian Bellisario), Emily (Shay Mitchell), and Hanna (Ashley Benson) follow Lesli's tracks to find the best proof that she is the one responsible for all their misfortunes. But as always, "A" is still one step ahead of their game. 

The official synopsis for the episode reads:

With all signs pointing to Lesli as the tormentor in the hoodie, the PLLs are on a mission to get concrete proof before bringing their findings to the police. But as the girls ramp up their investigation, 'A's' threats escalate. ​Meanwhile, a friend of Emily's makes her a surprising offer, and Spencer is pressured by her family to make an important decision." 

Meanwhile, in the teaser for the upcoming episode, the Liars discover that "A" implanted a tracking chip on them, which is why he or she knows exactly where they are. But the Liars are not the only ones who are being followed since Sara (Dre Davis) tells Emily that she can feel someone following her. However, Emily assures her new friend that she will not let anything bad happen to her. 

Will the girls finally find out who the root cause of all these is despite all the threats that "A" sends their way? 

PLL fans must have to wait for two more weeks before they find out the answer since the show will take a two-week hiatus before episode 6 airs on July 14 on ABC Family.
