Pretty Little Liars is known for its constant twists and turns, which means fans trying to keep up with the show are always thinking outside the box to try to stay ahead of the writers. The result is a fandom overflowing with cool ideas about what's going on in Rosewood, so each week we like to delve into the wilds of Tumblr to highlight an interesting theory.

This week, we want to talk about a theory that we think makes a lot of sense: That "A" really is targeting the N.A.T. club, and it's because their videos hold evidence about who "A" is.

The idea that "A" has been going after former N.A.T. club members is nothing new; in fact, it seems fairly likely at this point. After all, both Ian and Garrett are dead, and it definitely seemed like someone wanted to add Jason to that list when they messed with the elevator and landed him in the hospital.

The question has always been "why?" Many fans have assumed that it has to do with the N.A.T. club's involvement in the night Ali died. After all, they were all around that night and knew bits and pieces, so it made sense.

However, the idea that N.A.T.'s cameras caught evidence of "A"'s wrongdoings also make sense. Maybe even more sense. After all, if "A" was trying to find Ali, why would they off people who might have evidence about what happened to her? On the other hand, if "A" caught wind of potentially incriminating evidence on the N.A.T. tapes, we could certainly see them stopping at nothing to make sure they weren't found out.

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