However, the Liars just found out that Mary Drake actually gave birth to two children - one is Charlotte (Vanessa Ray) and the other one is said to be a guy. Both would've been around the age of Aria (Lucy Hale) and her friends.

According to TV Line, it's possible that Aria is related to Mary and she could also be the real daughter of her adopted dad Byron's brother Scott. The latter also spent some time at Radley after suffering from a mental illness.

Last Tuesday, A.D. stole Aria and Noel Kahn's files from Jessica's cellar that was filled with so many other mysterious items. However, it was only Noel's files that were burnt. Aria's files, on the other hand, were kept seemingly for future use.

Meanwhile, another theory shared by the publication has to do with Jessica's friendship with Aria, Hanna (Ashley Benson), Spencer (Troian Bellisario) and Emily's (Shay Mitchell) moms.

During that time, Jessica and Mary were still residing in Rosewood, but it wasn't long after that the former turned her back on the latter and asked her to skip town. Since she could have been feeling lonely, Jessica decided to reach out to the moms of her daughter Alison's (Sasha Pieterse) friends.

In other news, the publication also noted that there have already been so many speculations suggesting that Aria is the real "A." In fact, there was a time when a Reddit user claimed that Aria was the one who was sent to Radley. While there, she made up stories in her head about having friends. However, none of these happens actually happened in real life.

As of late, none of these theories have been confirmed or denied by executive producer Marlene King. But Hale previously told Access Hollywood that she doesn't have any problem being written as the villain of the hit Freeform TV series.

"Pretty Little Liars" season 7 airs Tuesdays at 8 p.m. ET on Freeform.
