Pretty Little Liars Boss Previews 'Juicy' Season 4, a Major Mon'A' Twist, Ezria's Sad Fate and More!

Pretty Little Liars Season 4 SpoilersIf Pretty Little LiarsSeason 3 finale left you with a slew of burning questions, you’re in luck: TVLine tracked down the ABC Family drama’s exec producer Oliver Goldstick and got to the bottom of all things “Red Coat,” “Spoby,” “Ezria,” “Mon’A'” and much more!

Read on to learn what fates await your favorite Rosewoodians in Season 4, which bows June 11 at 8/7c:

TVLINE | I’ve got a bit of a bone to pick with you about this Toby revelation: Over the past year, you’d convinced me that he had good reasons for hating all of the girls — and that those reasons were very real.
I’ve got a job to do here, Meg! [Laughs] I’m supposed to be titillating and playing with you as well, to some degree. Now, you will see a flashback early on in Season 4 between Toby and Alison, and you will know that he had strong feelings about her — and he assumed the girls were the same way. Things have changed because he got to know Emily and then Spencer very well, but I don’t regret saying that because he had a lot of residual anger and animosity toward these girls for what happened to him.

TVLINE | Will his working with Spencer in the finale impact his covert role within the “A” team moving forward?
The thing that really is cool in Season 4 is that Toby has a storyline where “A” — the “A” team and “Red Coat” — lures him back in. It’s a very emotional and interesting storyline for him. I won’t give away too much, but he deals with some very personal stuff that “A” knows about him.

TVLINE | The tables have been turned on Mona. Is she now part of the group and also on “A”‘s hit list?
Yes, Mona is. She’s still a vicious little dumpling, we know that, and she will remain that. But it is very cool to come into Season 4 with five PLLs, and that’s what we’re doing — which is what it was when Allison was still “alive.” We come into Season 4 exploring what it means when you get an adjunct PLL, which is now Mona, their former tormentor. You want to keep her close, because God knows she has more insight than anybody into who’s been doing this to them.

TVLINE | But does anybody actually trust her?
As far as trusting her, I always think of it as a spectrum; Hanna may trust her most, only because they shared a year of close friendship, but Spencer sees her as an attention whore who she’d never trust.

TVLINE | We’ve seen many sides of Mona over the seasons. Will this development create another new version?
Because of some other events and what happens with [Wilden’s car’s] trunk, and how game-changing what they find in there is, it shifts the relationship to where Mona might be needed. She becomes more necessary to them, and they can’t necessarily ostracize or antagonize her. Mona may have a three-hour time limit on being good, but you’ve got to take advantage of those three hours! [Laughs] Because of what happens in the trunk, they might need to have her around.

TVLINE | Speaking of that trunk, what can you say about its contents?
You’ll know what’s in there in the Season 4 premiere. And we pick up the season really moments after where we left off in the finale… I don’t know if you realize this, Meg, but we’re in senior year now and it’s going to move very slowly. [Laughs] It’s like, will high school ever end?!

TVLINE | We may have seen the face of Red Coat, though we can’t really trust it because they girls were so out of it…
We’ve also introduced masks, as you know. There was an Alison mask that we saw last week.

TVLINE | Why reveal it in that way?
For us, we felt like the girls had to catch up with an audience that strongly suspects that Alison is pulling the strings and is alive. We felt that it was time our girls were on the same page as viewers.

TVLINE | Where does the start of Season 4 find the newly split Aria and Ezra?
She’s got to move on. It’s gonna be tough, as he’s going to be her teacher, standing in front of that classroom. But she’s got to move on.

TVLINE | But the show’s EPs have said over the years that “Ezria” is endgame. So, is this just something they’re going through for the time being?
Yes. There’s some shocking developments with Ezra Fitz in Season 4. I cannot tease them, but your eyebrows are going to fall off! Hold onto them! [Laughs]

TVLINE | You raved earlier this year about Troian Bellisario’s arc in Season 3 — and rightfully so. Does anyone new have a standout storyline like that in Season 4?
Several, actually. Hanna’s got something that’s very juicy — juicy, juicy, juicy, juicy, juicy. [Laughs] And Emily and Aria have personal arcs that are really interesting, as well.

TVLINE | And lastly, just because you’re always so good at this, sum up Season 4 in a few words.
Is she or isn’t she? Only air traffic control knows for sure… [Laughs]
