pretty Little Liars season 6
Hanna, Emily, Aria and Spencer are still clueless about their kidnapperABC Family

Pretty Little Liars season 6 is unravelling one truth after another about Charles DiLaurentis since its summer premiere.

However, Alison's father's suspicious attitude has triggered many more questions than answers. In the previous episode, Mr DiLaurentis revealed that Charles was his son, older than Jason by 15 months.

But he and Ali's mother kept his identity a secret as he was mentally unstable and dangerous. He was eventually institutionalized at Radley because he became a threat to his younger siblings.

To Ali's shock, her father Kenneth reveals that Charles killed himself by when he was 16 years old by consuming some pills and Mrs D cremated him.

In the promo of the upcoming episode titled She's No Angel, Ali remains suspicious of her father and believes that more secrets are buried under the DiLaurentis backyard than what her father revealed to her.

The official synopsis of episode 5 reads:

Mona returns to Rosewood in a very fragile state as she must answer to the police for faking her death. Matters only get worse when she is confronted by Lesli's sister about Lesli's inadvertent involvement in Mona's plot. Hanna is determined to help Mona out, not only to reassure her she is safe from Alison but also to try and repair Mona's friendship with Lesli. Emily tries to help Sara with her troubled home life by encouraging her to explore the possibility of emancipation. Spencer, on the other hand, finds help from someone from her past. Meanwhile, Alison grows closer to Lorenzo as she looks for support outside of her family.

Mona has returned to Rosewood after being rescued from the dollhouse but she will have to face police and her taxpayers for faking her death.

The liars, Aria, Spencer, Emily and Hanna, meanwhile, are searching for answers about A and his/her connection with Charles.

After episode 5, the popular teen thriller by ABC Family will go on a hiatus for two weeks and will return with a five-year time jump.

Pretty Little Liars season 6 airs every Tuesday at 8pm ET on ABC Family.
