Pretty Little Liars has proven that it's willing to go for just about any twist, including making the leading man in the show's central romance a possible baddie. If it can go that far, what won't it do? At this point, we're not convinced there's any line it won't cross, which is why we like to dive into the world of awesome, crazy fan theories every week. After all, with this show, it's possible one of these seemingly out-there ideas might be right.

One theory we've discussed before is that Aria herself is "A", or at least involved with the "A" team. Today, we want to delve into a specific subset of that general theory — that our beloved artsy Liar is actually suffering from a split personality; one half the kind, quirky character we know and love, and the other the evil mastermind behind it all.

Where does this idea come from? Well, first you should go read about why people suspect Aria of being "A" at all, because this idea springs from that. There are all these reasons to think she could be up to no good, but that just doesn't jive with what we've seen of her character on screen. Aria having multiple personalities is one way to resolve the question of why this seemingly loyal friend would turn on her besties.

Still, it's not just a convenient explanation. There are a few reasons to think it could be true.

The Mirror Imagery. As this Tumblr user points out, Aria has been associated with a lot of mirror imagery, and mirrors are often used to symbolize someone looking at their "true" self. Could Aria's link to mirrors be a suggestion that there is much more to her than meets the eye?

The Psycho connection. The writers have talked endlessly about how much inspiration they draw from the master of horror himself, Alfred Hitchcock. Every finale is linked to a specific Hitchcock movie, and he's clearly had a big influence on the PLL writing staff. As this Tumblr user points out, the most famous Hitchcock film of them all, Psycho, revolves around a killer with a split personality. It wouldn't be surprising to find out the writers decided to follow in Hitchcock's footsteps.

What do you think of this theory — is it possible, or totally crazy? Sound off in the comments below.
