“Wayward Pines” brought its second season to an end Wednesday (July 27) with a finale that was both a cliffhanger and kind of a downer. Executive producer and author of the book series Blake Crouch tells Zap2it that the cliffhanger is in place for a possible third season, but it won’t be some happily ever after for the citizens of Wayward Pines.

Here are six things for fans to know about the finale…

The Kerry/Jason reveal was planned far in advance

“We actually came up with that earlier this year, in January,” says Crouch. “We had the writers’ room and I went out to see [executive producer M. Night Shyamalan] and we had a few days just talking about the season … and that’s one of the things that came out of that brainstorming session —  we have this character who’s running Wayward Pines now who is basically partnered with his mom and what’s cool about it is only ‘Wayward Pines’ could do that, with the way that we play with time and the idea of suspended animation.”

He also agrees that while it’s definitely icky, it makes a lot of sense that Jason (Tom Stevens) would pluck his own mother (Kacey Rohl) out of a pile of medical files.

“It’s kind of creepy, right? But we all end up marrying our mothers and our fathers, basically, or so psychologists would lead us to believe, so it makes total sense he would be attracted to his mom not knowing that she’s his mom.”

CJ did not terminate the town … but he gave it some serious thought

“That was another idea we had floating around, because CJ (Djimon Hounsou) is our extinctionist. He has seen more of mankind’s downfall than David Pilcher. He was there watching the world fall apart, so CJ has this epic knowledge of watching the downfall of mankind and we were leading up to this moment where he’s waiting after everyone’s gone into the suspension pods, he has this moment of, ‘Is it our time? Should I do it?’ and we really debated whether he was going to push that button. But it didn’t feel like that was keeping with his character. He was an inherently decent man and he’s not going to murder the rest of the town.”

The Kerry/Abbie cliffhanger does not have anything to do with Adam Hassler

“I don’t think the intention was for Adam Hassler (Tim Griffin) to have anything to do with it.”

But it is left open-ended for a reason

“Two things – Kerry going out beyond the fence is a little open-ended. Did she do what she set out to do? That remains to be seen,” says Crouch. “And 2, the baby — the idea is that humans evolved into abberations, but evolution doesn’t stop, even for the Abbies, so the idea is what are the Abbies going to become? Are they going to become something more human? Are they going to get worse? And now the town’s back in suspended animation, so we wanted to drop that breadcrumb of what world might be waiting for them when they emerge from the suspension pods.”

There is an idea for Season 3 in place

“We came up with a three-season arc, so in a perfect world, if we have the chance, we would conclude ‘Wayward Pines’ in a third season. And that would be it, we would be done,” says Crouch.

He adds, “I think we’ve set up a pretty big premise with the idea of half of Wayward Pines going back into suspension and what awaits them when they step out? What happens to those who were left behind? And what is the state of the Abbies when we find them?

“‘Wayward Pines’ has always been about mankind and the idea that our time here on the Earth is not infinite. We are a blink of the eye in terms of the evolutionary forces that go on in the universe. We’re here for a minute, but we feel like we’ve always been here and we will always be here — and that’s not the case. So the questions that interest us are if mankind is facing extinction, like definitely, absolute extinction, what is that final phase like if a species is aware of its own demise? Humanity knowing that it’s the last of its kind, what does that level of awareness look like? Do we face that bravely? Are we afraid? … We’ll see, if we’re lucky enough to continue the story.”

But don’t expect a happily ever after ending

“I hope [the series finale] would stay true to the theme and the tone we’ve established. I wouldn’t want to sell it out and go for some cheesy, hokey ending just for the sake of letting the audience be happy in the last moment and I don’t think the audience would want that either. I would want a real ending that is honest and would probably have some incredible poignancy and bittersweet moments. The idea of what the last episode looks like is very exciting.”
