The reveal that Ezra is “A” came as an abrupt plot twist to us, but how long have the Pretty Little Liars Powers That Be been sitting on this secret? Showrunner Marlene King talked to Entertainment Weekly about when the decision to make Ezra “A” happened.

How long have the writers known?

“We started talking about this when we were making the decision to reveal Mona as Original ‘A,’” Marlene told EW. Since the Mona as “A” reveal happened in the Season 2 finale, this means those sneaky PLLers have been thinking about Ezra as “A” since Season 2!

Need your mind blown a little bit more? Though the PLL writers started seriously discussing Ezra as “A” in Season 2, they’ve been considering it since Day 1: “It’s always been in the back of our minds, even going back to the pilot, because he was such a ripe character,” continued Marlene. “He has always been, interestingly enough, he shows up when the text messages start showing up. Aria was looking at that Ali poster in that bar when he introduced himself to her, and he’s been in interesting places at the right times very often. So lots of fans had the theory early on that Ezra was on the “A” team, so we’ve always been writing with it in the back of our minds.”

Interesting… we’ve been operating under the assumption (and Marlene has confirmed it) that Mona was the Original “A” in the first two seasons, then Uber “A” swooped in and stole the crown — er, black hoodie — from her. Could Ezra have been involved in the “A” game even when it belonged to Mona?

How long has Ian known?

“I’ve known about it for a while,” Ian told EW, regarding the info that his on-screen counterpart is masquerading as “A,” though some of the intel was new. “To what extent I was unclear of only up until a couple months ago,” he added.

According to Ian, the PLL Powers That Be spilled on the plot twist way back in February. Ian became interested in another project and went to ABC Family to discuss his future on PLL when Marlene spilled the beans: “Marlene King actually said, ‘Hey, we can’t let you go because of what’s going to happen with Ezra,’” Ian relayed. “I’m like, ‘Oh, what’s going to happen with Ezra?’ She alluded to the sudden shift in his character arc that would happen toward the tail end of 4A and then would continue in some way, shape, or form into 4B.” Bring it on, PLL!
