ON THE NEXT EPISODE
The Survivors react to Butch's bizarre behavior when he obsessively stacks firewood everywhere throughout the camp.
Returning to their camp, the Survivors find devastation after a fire rages through their shelter and belongings, leaving them with nothing but the clothes on their backs.
Believing they are on the chopping block, Jenna and Heidi refuse to help in rebuilding the camp. Will this seal their fate?
One Survivor is worn out and sick, and begs to be voted out. Will the others comply?
