We demAnd Answers!

The Pretty Little Liars finale gave us the identity of “Big A” but left fans with more questions than ever.

PLL boss I. Marlene King holds all the secrets, but she isn’t spilling them … yet. The ever evasive executive producer did tell PEOPLE what we can expect in June’s season 6 and hinted that the person at the center of Tuesday night’s big reveal may not be the last A the Liars have to unmask.

Stop reading now if you haven’t seen “Welcome to the Dollhouse” and want to avoid spoilers from PLL‘s season 5 finale.

Now that we know Charles DiLaurentis is Big A, is this the show’s take on the books’ twin twist? So does that make A the half-brother of both Spencer (Troian Bellisario) and Alison (Sasha Pieterse)? Is Charles the reason Jason (Drew Van Acker) went MIA throughout the series? And what is up with Varjak?!

The finale implied this pretty heavily, but can can you confirm that Charles is Jason’s twin, or at least his brother?
I can not confirm that, but that will be confirmed, one way or another, within the next few episodes.

There’s been a lot of talk about Big A versus Über A: Is he the final A for the next two seasons?
I will say that Mona (Janel Parrish) was Original A, Charles is Big A, and I don’t want to hint to where the show is going after that just yet. Sorry!

What about one of the most prevalent fan theories, that Aria (Lucy Hale) is A?
I read that a lot. That is a good theory. That’s all I can say! [Laughs.]

Last night answered a lot of questions, but I’m still curious if Varjak factors into this, or was that a red herring?
We haven’t heard the last of Varjak.

Is it possible we’ve seen Charles before, thinking he was Jason or another character?
Yes, that is very possible.

Did Mona know Charles in Radley? She seemed to know his name, at least, when she left the girls that anagram a few episodes ago.
Well, we’re going to get into that next season because last night, as you watched, it seemed like that was new information to Mona. So she might not have been aware of those anagrams left at her house.

When you "killed" Mona, did you know you d bring her back? Was that always the plan?
Yes, always. And it was so hard to keep that secret from Janel Parrish, but yes, we always knew that she wasn’t dead. We have serious spoiler attempts on this show, so to make sure we could pull that off we sort of lied. [Laughs.]

How do you explain her looking so dead in the trunk of A’s car?
It’s interesting, you’ll get a sense of that when we come back. That’s kind of not the last time you will have seen a character seem to be dead.

Should we be thinking that Charles is both A and the person who murdered his mom and Bethany, or could there be another killer out there?
There could be another killer out there, and I’m happy to tell you the answer to those questions – I think all of the remaining unsolved murders – will be addressed in the next few episodes.

You Tweeted that the Ravenswood mime Charlemagne was a clue about Charles. Are there any other breadcrumbs you could point to that would help us trace it back to the beginning of the series?
There are some hints in the Christmas episodes, there are a lot of hints in season 4 and a few hints in season 3. This story really started when A stole the game from Mona, so this story really started with episode 301, and it will be ending with episode 610. By the end of our summer finale, we will have finished this story for our Pretty Little Liars.

Let’s talk about Andrew (Brandon W. Jones). He started off as this cute guy Spencer knew, but this season he’s been doing some very sketchy things, and the hijacked fan was found on Campbell Farm! Is he connected to Charles or is he operating on his own?
The connections aren’t random. He’s definitely involved in this, and we will find out in the next couple episodes to what extent and what’s going on with Andrew.

Are there characters on the show – I’m thinking of Melissa (Torrey DeVitto), the Hastings parents, Jason – who may have known about Charles before the Liars did?
Well, there may be. I mean, somebody has to know about Charles because he was born, he has parents. [Laughs.] I know, it’s so hard! I hope that was a little bit helpful.

You just started filming, but what are you most excited about for season 6?
We’re starting our 121st episode right now, and it’s been a long journey and a really fun journey of going over hills and around mountains to get to the finish line. But we are running straight for the finish line now, and it’s just so exciting because we have so much momentum with us. Last night was the beginning of the end, and the next 10 episodes are all about layers and uncovering the deeper understanding of who is Charles and why. It’s not just a surface-level story. It’s very deep and complex, but we’re about to simplify it for everyone, and hopefully our fans will make sense of it before we even tell them the answers. Some of them already have figured it out!
