If you’re hoping that the gut-punch of a reveal that took place in Tuesday’s Pretty Little Liars summer finale was yet another of the series’ misleading twists, you’re out of luck.

Turns out, the addictive ABC Family drama plans to stick with (to some degree) the shocking notion that — SPOILER ALERT — Ezra is ‘A’!

“I assure you that there is something going on here with Ezra,” Liars executive producer Oliver Goldstick tells TVLine exclusively.

But that’s only just the tip of the iceberg. Here, Goldstick discusses surprising details about the Rosewood fave’s “double life,” how this twist will put Aria (among others) in danger and much, much more.

TVLINE | I’ve got to be honest with you, I feel like this is the same situation I was in a year ago with you right after the big “Toby is ‘A'” reveal…

You’re not. I promise you you’re not. I assure you that there is something going on here with Ezra. There is something very real going on here. I can’t give you too much information, but I can tell you it plays out quite beautifully in Season 4B. And Aria’s in danger — well, they all are, but Aria in particular.

TVLINE | So, are you confirming that this is not a red herring?

Yes, there is something that is about to be exposed and revealed in 4B. I guess what I’m saying is that this is going to escalate and be more explosive and mind-blowing.

TVLINE | And this all begins in Season 4B or before that in the Halloween special?

Because of the nature of the Halloween episode, the mystery of [Ezra] doesn’t move forward that much; it’s a standalone episode… As far as the explosive revelation of last night, it builds on that without giving you explanations. It builds on Ezra’s culpability of being ‘A,’ but it doesn’t explain a lot of questions you’ll have as an audience. You have to wait for 4B for that.

TVLINE | Should we have come away from the finale with the idea that Ezra is ‘A’ or is on Team ‘A’?

I can’t give that away, I will just say you’re really in hot territory and very close.

TVLINE | For me, this all could make sense because ‘A’ began his or her torment once Ezra came to Rosewood. What doesn’t make sense though is how decent he’s been and how much he’s loved Aria.

I hear you and we can answer that in an emotionally satisfying way. Everybody here is very aware of that, too, because this is a relationship that’s deeply romantic. They’re soulmates, and we’ve invested so much into them. We’re going to be able to explain some things to you.

TVLINE | ‘Ezria’ has been touted as “endgame” since Day 1, so what can you say about that now? It seems this will definitely impact that–

Oh, it impacts it — in a big way! [Laughs] Not right away, but you’ll stand by and say, “Gee golly, gee whiz, what is going on?! How can this person be living a double life?” What you’re really going to find out is this whole Jekyll-and-Hyde factor about Ezra — it’s going to blow your mind.

TVLINE | Talk about the evolution of the idea to go in this direction with Ezra.

We knew from the beginning of this season. When Ezra and Aria weren’t together, we sort of tracked and mapped them as a couple — he’s basically microchipped like a dog! He’s had it since we started the show. So, we know where he’s been, and it’s not always a good place. Sometimes he’s eaten out of a dumpster! [Laughs] We really have tracked this.

TVLINE | Are the fans who have gone back and tracked why Ezra is ‘A’ onto something?

That I can emphatically answer: Yes! That is not bull; those things have been planted. We were subtly putting things in and you can track them, and hopefully in 4B you’ll be able to help us solve this puzzle.

TVLINE | Since Aria won’t be in on Ezra’s secret immediately, what does this mean for them as a couple in 4B? Also, what does this mean for Jake?

Jake is returning, and it’ll be very complicated. We know he cares for her and she cares for him, and more than anything, he’s concerned for her welfare because when they met, she was under duress… So her duress escalates in 4B, and he wants desperately to protect her, but she won’t let him — because she’s got Ezra, right?! [Laughs]

TVLINE | According to Mrs. Grunwald, Alison is alive. Was that meant to be a definitive reveal to the audience?

Not definitive, just a suggestion from someone who had dealings with her on that night…

TVLINE | Will the girls be on a mission to find Ali moving forward?

Yes…

TVLINE | What can you say about the identity of a second Red Coat?

That is indeed still an issue. People have come to the conclusion that there has to be more than one person; there has to be an ‘A’ team, ultimately. But we’re not saying that’s necessarily true either, it’s just a very valid theory.

TVLINE | Talk a little about what happens, once Caleb is in Ravenswood, to keep him there permanently.

At the end of the Halloween episode, there’s a twist that provides a compelling reason for Caleb to at least stay there temporarily to explore what the hell something is. It pertains to him; it’s not about Alison or Hanna.

TVLINE | What else can you tease about the Halloween special?

It’s really fun and it’s juicy. you’ll get more episodes regarding Mrs. Grunwald and Alison — some great answers. You’ll get some escalation of whether you suspect Ezra of being The Devious One! [Laughs] There’s a really good pursuit of Alison because the Liars have every reason to believe now that she’s still with us. If she’s going to be in this town on this holiday, they’re not leaving here until we find her.
