Pretty Little Liars season 6
Alison and Charles at the Rosewood High promABC Family

Pretty Little Liars season 6's summer finale is upon us and it will finally reveal the real identity of A aka Charles DiLaurentis.

The first two minutes of the summer finale titled Game Over Charles reveals the terrifying faces of Alison, Aria, Emily, Spencer and Hanna as they follow the hooded villain to the terrace on a building.

While he attempts to jump off in order to kill himself, a visibly disturbed Ali requests him not to do so while Aria and Emily try to make him understand that they are eager to forget the past and all the tortures inflicted on them by him because he is Ali's brother and they have sympathy for him.

It remains to be seen whether he comes back to the liars or if he commits suicide.

The official synopsis of the teen mystery thriller's summer finale reads:

"Who killed Toby's mother? Who hit Alison in the head with the rock the night she went missing? Who is Red Coat? Who killed Bethany? Who is the Black Widow? Why has 'A' been targeting the PLLs all this time? After years of torture, Alison, Aria, Emily, Hanna and Spencer finally come face-to-face with their tormentor and learn the story of how and why Charles became "A.""

A Reddit leak already reveals Dr Wren Kingston of the Radley as the hooded tormentor of the girls. According to the anonymous user, Wren is a year older to Jason and has never been to Oxford. In fact, Alison's mother framed Charles' suicide and joined the board of the sanatorium in order to cover the whole thing up and keep him safe with a secret identity.

Meanwhile, Sasha Pieterse (aka Alison) reveals that her character's fate will shock everyone in the finale. This has prompted fans to believe that Alison will die after she comes face to face with A.

A recent picture of the liars released by ABC Family does not feature Ali in it, triggering the fear that the DiLaurentis daughter may finally die.

"It was the opposite of what I thought would happen to her," Pieterse tells TV Line. "It made sense once the writers explained the storyline for Alison. I was able to kind of understood their mindset after that. So the fans are going to be shocked, but at the same time, they'll appreciate it. Alison had such a weird childhood, and you'll see more of that as you get answers in the finale. She wants normality, which she gets, but in a way you wouldn't expect. The location is not where you'd expect her to be."

Pretty Little Liars season 6 summer finale will air on 11 August on ABC Family.
