This 'PLL' Fan Theory About The Identity Of 'A.D.' Is So Insane, It Could Actually Be True

Pretty Little Liars fans, don't freak, but a new fan theory just changed everything about uncovering the identity of "A.D."

With only a few episodes left, we're getting closer and closer to the reveal of "Uber A" – the baddest of them all. But who could it possibly be? 

US Weekly reports that Tyler Blackburn dished a small secret regarding the identity of A.D.: 

"You've never met them ... You kind of have," he said. "When you see it, you'll understand what I'm saying."

Totally confused, at first, his response got us thinking ... A.D. is someone we haven't met, but will recognize?  

One crazy popular fan theory might be able to explain – and it's tied to one of the Liars. A twin theory has taken over Tumblr. The idea? Spencer Hastings has a twin. And that twin ... is A.D. 

After it was revealed that Jessica DiLaurentis and Mary Drake were twins, the twinning idea became a total possibility. Not to mention, Teen Vogue points out that there's some pretty hard evidence to back the theory. 

Remember the first episode of season 7, when Hanna was being held captive? She was "visited" by Spencer. Of course, Hanna believed it was a dream, but was it? We've learned by now that things are never what they seem, leading the Internet to think that Hanna was actually visited by Spencer's twin. Not to mention, this Spencer 2.0 sings the same lullaby to Hanna that Mary Drake sang to Spencer after she got shot. Creepy.

Plus, the Teen Vogue team also points out that Spencer wasn't sportin' her signature bangs in the clip. What do you think? Was Hanna dreaming? Either way, we won't have to wait much longer to find out!
