'Wayward Pines' Fox: An Entirely Different Cast Needed For Season 2? Fox Eyes Renewal

Dr. Piltcher (Toby Jones) has officially gone around the bend, and his apparent insanity will lead to an all out war with the Abbies as season 1 comes to a close. Luckily, the town's resistance will be locked and loaded as their world spirals out of control.

"It's all out war," Carla Gugino (Kate) said in a preview for "Cylce." "[Kate's] got a machine gun, she's got pistols, and she's got bombs in one bag. I mean, she is ready."

Despite this, Kate won't be able to save everyone. Actor Charlie Tahan (Ben) ominously announced that there will be "a lot of gun fire, a lot of Abbies, not too many survivors."

The Pinesians only have one hope of bringing the electric fence back online, and that lies with Nurse Pam (Melissa Leo). Originally one of the creepiest characters in the mysterious town, Piltcher's sister could be a major boon to Ethan (Matt Dillon) and his family as the walls come tumbling down,

Will Pam be able to make her brother see sense before yet another iteration of Wayward Pines is obliterated, or will the Abbies have their day? Find out when the Wayward Pines season finale airs Thursday at 9 p.m. ET on Fox.
