'Pretty Little Liars' Season 7 Spoilers & Theories - Uber A Is Out In The Open, They've Been With The Liars All Along

Pretty Little Liars won't be aired until next year, April 2017. However, this long hiatus does not stop fans from trying to figure out who the big bad is.

Throughout the show's six -ear run, there are probably thousands of different theories from the fans. Out of a thousand theories, showrunner I. Marlene King has revealed that she only saw two theories that almost nailed it... almost.

This revelation has caused millions of fans to search the internet far and wide to find out which theory was right. However, with all of the theories, no one could possibly know who got it right until the show returns and finally reveal who Uber A is.

One of the best theories out there is that Uber A was with the liars all along. After all, the big bad himself/herself has revealed he/she are not hiding in the shadows.

In the previous episodes of "Pretty Little Liars" season 7, fans saw a masked person several times. This person has been using disguises, running around Rosewood as a bellboy, a housekeeper, a mailman, etc.

Now, this obviously means that Uber A can get near the liars without any of them suspecting a thing. But what if this was merely Uber A's helper, and the big bad is actually amongst the liars?

Fans are definitely loving the idea that one of the liars could potentially be Uber A. While there is an abundance of clues pointing towards Aria Montgomery (Lucy Hale), one liar is still more mysterious above all: Spencer Hastings (Troian Bellisario).

Pretty Little Liars' mid-season finale revealed that Spencer is actually Mary Drake's daughter. This means she is Charlotte's biological sister. But what if Spencer is not actually Spencer, but instead a twin?

Several theories online point out that Spencer has been different since the show's five-year jump. Her stay in Radley is also no secret.

The creepy child Spencer saw in Radley Sanitarium could also be a foreshadowing of her own twin sister. It is also highly possible that Spencer's twin has been switching places with her all throughout the show.

If this twin really is Uber A, then it will explain how she is always one step ahead of the liars. And how she got access to their personal belongings. She was with them all along, and the liars never suspected a thing.
