Pretty Little Liars isn't a show that shys away from extreme twists and crazy solutions to its many mysteries, so sometimes we have to think outside of the box when trying to speculate about what the answers are. With that in mind, we want to present one of our favorite totally bizarre but still plausible theories about the show: That Alison DiLaurentis (Sasha Pieterse) has multiple personalities, and one of them may even be "A".

What's this theory all about? Let's break it down.


Ali has always seemed like two different people. Ali is a complicated character. In fact, sometimes she seems like two totally different people — the scared teen who really does want to make amends, and the stone cold manipulator who always gets what she wants. Is that more than just a layered personality? Could Ali really be two different people in the same body?

It's a twist on the twin theory. In the Pretty Little Liars books, it turns out Ali has a crazy twin sister. Many fans think the show is going to go down a similar road, but the writers have insisted they won't make Ali have a twin like she does in the books. What if on the show it's not Ali's twin that causes problems, but a sinister second personality that lives inside her? Same kind of idea, totally new take.

Mental health is a big part of the story... Radley has been at the center of the story for seasons, and Mona's "A" exploits were explained by her living in some sort of "hyper-reality," so this twist, though extreme, wouldn't be totally out of left field.

What do you think: Is this theory possible, or just crazy? Let us know in the comments below!
