“The 100” Season 2, episode 12 is about to make life at Mount Weather a lot more uncomfortable. Jasper (Devon Bostick) made the choice to leave last week, but it seems President Wallace’s (Raymond J. Barry) decision to let the kids go is no longer final. The 47 are officially prisoners now, according to a new sneak peek video.

Sneak Peek No. 1

Jasper is still excited that he saw Bellamy (Bob Morley) in Mount Weather, but the others aren’t sure if Jasper saw clearly. It just sounds a little too good to be true. “It was Bellamy,” Jasper says. “I’m telling you, he’s here.”

They don’t have time to argue, though. Dr. Tsing (Rekha Sharma) is taking her next victim, and she comes in with about 10 armed men. Harper (Chelsey Reist) is grabbed first, and it looks like she will be taken away again -- until the doctor intervenes. “No, not her,” Dr. Tsing says. “She needs more time to recover.”

They take another boy, and Jasper tries to stick up for them. “You can’t keep doing this to us,” Jasper says. “President Wallace said we could go.”

“That President Wallace is no longer in command,” Dr. Tsing says, implying that his son has taken over. "He had to step down for health reasons. I’m sorry it has to be like this. I hope you know you’re all incredibly special to us.”

Sneak Peek No. 2

Bellamy is on a mission to rescue his friends. He has taken a guard’s uniform and sneaks into President Wallace’s room. He serves him food and Wallace immediately knows that he isn’t a legitimate employee. Bellamy says Jasper sent him. “We need your help,” Bellamy says. “Your son is killing my friends.”

“I’m a prisoner, same as them,” Wallace says.

“A prisoner who knows every inch of this mountain, every security measure,” Bellamy reminds him.

Wallace informs Bellamy that there was extra security put in after Clarke’s (Eliza Taylor) escape. “My son has no doubt changed all entrance and access codes by now,” he says. “Your friends will never even make it off Level 5.”

“I won’t let them die here,” Bellamy says.

Wallace apologizes and says he cannot help anyone escape, and Bellamy turns to leave. “But I may be able to buy them some time,” Wallace says.
