Tonight is the series finale of Pretty Little Liars and fans will finally find out who the ultimate villain is on the show. Previously, it was revealed that the character Mary Drake, was the biological mother of Spencer Hastings. But, did Drake perhaps have two babies she had to give up? Many fans believe that Spencer has a secret twin, who could be A.D., the major villain of the series. In an interview with Cosmopolitan, show-runner Marlene King said that A.D. is someone “we haven’t revealed yet.” Since we haven’t met Spencer’s twin, this could definitely be a possibility. King also told Entertainment Tonight:
So the A.D. reveal is very important but then the understanding of [why] is equally as important. That’s why [the finale] is two hours, so the fans and the Pretty Little Liars can all process it all at the same time.
Another theory that piggy-backs off the twin theory is that Andrew Campbell is actually Spencer’s twin, since we haven’t heard from him in a while. He did appear to be quite involved in the past and we do know that he is adopted.
Something strange that happened this season was an encounter between “Spencer” and Ezra at the airport. In their brief conversation, Spencer asked Ezra to not tell the other girls that she was there and who she was talking to (Wren). It was an odd moment and felt a bit out of character for Spencer. Could she possibly have an identical twin?
On a PLL theories forum board, a fan called “MrsWren” wrote about the scene, saying:
This scene last night: This Spencer had no watch, was wearing un-Spencerlike clothes and acting in a way that Spencer wouldnt have. Atleast not at that moment: She just found out about The credit card used. No way she would let all of that rest, call Wren out of the blue and yap about Cece. Her focus wasn’t on Cece atm. It was on Mary, Rollins and her cop lover trying to get her in jail. Our Spencer would’ve focused on a way to get that bill if she was to do something.
The fan also wrote:
The intro. The girl in the casket is wearing the same dress as Spencer is wearing.
Do you think Spencer has a mysterious twin, who is A.D.?
