What is EzrA hiding?

Regular viewers of the hit teen-drama series Pretty Little Liars will remember that Mr. Fitz, or Ezra, was revealed as 'A', the show's villain, in the mid-way Season 4 finale.

Since then, the once adorable Mr. Fitz, has taken on the persona of some sort of creepy stalker, prompting viewers to question the motive behind his strange behaviour.

Now, in the most recent episode, the ever-inquisitive Spencer Hastings discovers that Ezra is in fact 'board shorts', an attractive guy whom Alison apparently had a fling with before she went missing.

So, what is Erza hiding? Why is he eavesdropping on the girls' conversations and documenting their every move?

More importantly, what does he want with Alison?

I've gathered together a list of explanations that may explain the motivation behind Ezra's sketchy demeanor.

1. Ezra is evil. Quite simply, Ezra is an evil psychopath who enjoys torturing others, and who also has a fetish for teenage girls.

2. Private Investigator/Cop. Ezra was hired as a private investigator by someone in Rosewood to investigate Alison's disappearance. Ezra may also be working on the case alone as an undercover cop.

3. Undercover Reporter. In the vein of the Drew Barrymore film 'You've never been kissed', Ezra was sent to Rosewood as an undercover journalist to report on Alison's disappearance. Like many a typical reporter, Ezra has become obsessed with the case, and will stop at nothing until he finds out what happened to Alison.

4. Ezra is on the A-Team. Just like every other resident of Rosewood, Alison knew Ezra before she disappeared. Given that Alison has often been portrayed as a manipulate attention-seeker, there is a good possibility that she may have upset Ezra, providing him with a motive for wanting her dead.

5. Personality disorder. Ezra suffers from some sort of split-personality disorder. This would explain why Ezra often appears as two different people depending on who he's with and how he's feeling at a certain time.

6. Ezra has a twin.  There are two Ezra's, a bad one, and a good one. The good one is the one that is dating Aria, while the bad one is the one that is stalking the girls.

My favourite theories are numbers two and three. Let's hope the big reveal won't leave us disappointed!
