With Fox still mulling whether to pick up its sci-fi series Wayward Pines for a third season, rumors are rife that the season will feature a thousand-year time jump.

Humans and Abbies will finally coexist if the show returns for the third season after the humans emerge a thousand years later from their cryo pods.

However, author and executive producer Blake Crouch is singing a different tune as he shared in an interview with zap2it, that the humans will not wake up to a happy future.

"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," Crouch said.

He added that if Fox decides to renew the series, it would have to be the last installment as he and producer M. Night Shyamalan have crafted a three series arc for the show's entire run.

Meanwhile, the cliffhanger left at the end of the finale as to what the baby clutching the hand of an Abbie is being speculated to be a new breed that is far more horrifying than the first generation of Abbies.

The new species will look human on the surface but may actually pose a deeper threat to humans than their predecessors.

Aside from the new threat, new characters are expected to step up for the conclusion of the series if it returns to Fox next year.
