In Pretty Little Liars season 7 episode 18, when Ashley Marin asked Caleb if Hanna was covering for someone in Dunhill's murder case she said, "Is it Alison? She's always at the bottom of everything." Do you think Alison is A.D.? We have a theory... and it involves her teaming up with her aunt, Mary Drake, making A.D. two people rather than one. Intrigued? Read our theory below then, if you agree, vote for Alison using the PLL Suspect Tracker, brought to you by SIMPLE Mobile.
Mary Drake was A.D. while Alison was at Welby in season 7A.
Mary may have become A.D. to get vengeance for Charlotte's death, which would make her responsible for kidnapping Hanna. She initially teamed up with Archer Dunhill, who became convinced that Alison was Charlotte's killer. But when Mary worked out that she wasn't, she tried to get Archer to back off.
Once Dunhill was out of the picture, Mary got Alison out of Welby.
This would have been an ideal way for Mary to gain Alison's trust. And once they were at home together, they could have connected over Charlotte's death.
Realizing that they had both been screwed over by Dunhill would have only made them closer.
He took all of Alison's money, including the money he had promised Mary as part of their arrangement.
And after this, Alison always seemed to be quick to jump to Mary's defense.
Remember how desperate she was for Jason to give her a chance? Jason rebuffed her saying, "She's not Mom!" Perhaps Alison was further drawn in by Mary because she missed her mom? At the time, she said she felt like she had no one.
Alison would’ve had motive to join Mary after she found out her friends believed she was Charlotte's killer.
This was a huge shock for Alison, and it wasn't the first time that she had been betrayed by her friends. Remember when they turned her into the police for the "death" of Mona? She might have created the board game to get revenge, while Mary used it to find Charlotte's killer.
In season 7B, Alison has been away twice while the others were dealing with A.D.
This seemed pretty suspicious... Could she have been going to see Mary to make arrangements for the game?
She's also showed that she's still capable of being the mean Ali we once knew.
Her confrontation with Paige in the staff room showed a side of Ali that we haven't seen in a while. If she is one half of A.D., perhaps it's bringing out that meaner part of her again.
And she's proved she's still a great liar.
She's been questioned by Marco on multiple occasions but she's always kept her cool. Her incredible lying skills could make it possible for her to cover up being one half of the A.D. partnership.
But what about her pregnancy?
She may indeed be pregnant after Archer paid someone to carry out the procedure, but she could be lying about it being Emily's -- remember, it was Alison that got the results of the test which apparently confirmed it. This version of her pregnancy would be a good way to earn the Liars' sympathy and keep them from being suspicious of her. As for that scene in the baby shop, well it wouldn't be the first time an A has set themselves up so it looks like they're the victim -- Mona did exactly the same thing.
