'A' will be revealed in the Season 6 finale of "Pretty Little Liars" and all questions will be answered.

"Who killed Toby's (Keegan Allen) mother? Who hit Alison (Sasha Pieterse) 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?" reads a description of "Game Over, Charles" on SpoilersGuide. All of these questions and more will apparently be answered as season 6 comes to a close.

"After years of torture, Alison, Aria (Lucy Hale), Emily (Shay Mitchell), Hanna (Ashley Benson) and Spencer (Troian Bellisario) finally come face-to-face with their tormentor and learn the story of how and why Charles became 'A,'" the episode's description continues.

Will the Liars find out that Charles was just crying out for attention? Or is he really a bad person looking to hurt people for no reason?

Kenneth DiLaurentis (Jim Abele) recently came clean about Charles during Season 6. Meanwhile, Alison has started to think that Charles is not such a bad person after seeing him in an old family video.

Even as the girls try to unravel all this mystery, they are still recovering from being locked away in Charles' lair. This experience clearly left them with emotional scars, and recently their social lives have been affected.

In the last episode, Charles invited Jason (Drew Van Acker) to his birthday party. When his sister Alison found out, she thought Charles was out to get her and called the police. Of course, her plan fell through.

Charles also sabotaged Aria's work in the art show by replacing her picture with his own twisted photo of the Liars lying drugged on exam tables in his dollhouse, according to the Washington Post's recap of "frAmed."

Yet, Ali finds her old baby rattle when she goes hunting for more clues about Charles, which led her to believe that he still longs to be closer to his family.

What is Charles really after? Find out in the Season 6 finale on ABC Family Tuesday Aug. 11 at 8 p.m. to find out.
