Those who are supposedly "safe" at Camp Jaha will no longer be able to call their new home a sanctuary. With only 48 hours to evacuate, the Sky People will have to face down a Grounder massacre in episode 7.

"Everybody in camp Jaha has twp days to get out before they're all going to be massacred as a result of what Finn did in the massacre of [the Grounder village] and as a result of the 300 people that were burned alive in the finale episode last year," explained executive producer Jason Rothenberg in a preview.

While flambéing a couple of hundred Grounders was the price for The 100's safety, Finn's slaughter of women and children was an atrocity. As the Grounders prepare to retaliate for the senseless killing, the 47 trapped in Mount Weather will be busy cooking up a battle of their own.

"Basically, our kids in Mount Weather have decided, or realized, they're going to have to save themselves," Rothenberg explained. "They are now going to use their juvenile delinquency to their advantage and we have this amazing sort of Ocean's 11-like heist."
