Ezra Fitz (Ian Harding) is the character we're most looking forward to seeing more of during Pretty Little Liars Season 4B. Now that we know he might be "A", we need to know more about why he's potentially evil, and what he's up to. Fortunately, it sounds like we have plenty of EzrA to looking forward to when the show returns on January 7, 2013.

While the writers have remained mum about the details of Ezra's deviance, they have dropped some hints about what to expect from the sneaky teach this winter season, and we've gathered the juiciest Ezra related spoilers right here for your reading pleasure.

So, that "A" thing... As soon as the Ezra-is-"A" twist happened, the writers jumped online to assure (or terrify, depending on your point of view) fans that this isn't going to be a Toby 2.0 situation. While they won't say if Ezra really is the Big "A" behind it all, they do make it clear that he really is wicked, not just a good guy in the wrong place or another double agent trying to protect the girls. In fact, he's been following Ali for a long time now.

But...why? Obviously the writers also haven't spilled why Ezra is secretly evil, but we can expect answers about that over the course of Season 4B, including some Ezra-centric flashbacks. There have been hints that Ezra is leading a double life of some sort, and Ian Harding has insisted that Ezra is not a sociopath (and Janel Parrish agrees!), so whatever his reasons, they must be compelling.

Ezra and Mona. If you're interested in what, if any, relationship Ezra has to the original "A", you're in luck: He and Mona will share what looks like a very interesting scene in the winter premiere, and that relationship will continue to be explored over the season.

Ezria?! Of course, many fans are worried about what this reveal means for one of the show's central couples. You can get a full roundup of Ezria related spoilers here, but the short answer is that while Aria is going to flip out when she finds out the truth, all hope is not lost.
