The 100 are hyper vigilant, firm in the belief that the Grounders are coming. Bellamy informs Clarke that Jasper believes he can make more gunpowder and Raven thinks that she can turn that it into landmines. Clarke comments on the irony of surviving 100 years and returning to earth so that humans can go back to slaughtering each other and wonders if there is another way. Clarke adds that maybe Abby was lucky because she died quickly on the Exodus and that no one is coming down to save them.
On the Arc, Cain slowly comes to consciousness and finds himself alone, so begins to look for fellow survivors.
Back on earth, Octavia is supervising the smoking of meat and Bell snarks that she learned how to do this from her Grounder boyfriend. Murphy questions why Octavia didn't talk to Bellamy about getting a better job and she simply replies if she didn't do it, someone else would have to do it. Am I the only one wondering what the hell Murphy is still doing in camp? Octavia is working with ammunition and she is joined by Finn, who says that he keeps wanting to apologize but Raven assures him that they are good. Raven adds that she isn't just keeping busy but is keeping the 100 alive. Finn starts to leave and Raven assures him again that they are good and that she just wants him to be a happy. Okay the Grounders are probably coming, they have lost contact with the earth, and the Exodus has crash landed but by all means, take time to angst about the love triangle.. Calls of a fire break up the conversation and when Finn and Rave head outside, the smoke house is on fire. Octavia asks what they are going to do because the smokehouse contained all of the food.
Later, with the ashes of the smokehouse still smoldering, Bellamy tells Clarke that Bell kept feeding the fire because Octavia told him it was a bad idea. Yeah, we didn't need another reminder that the 100 are juveniles but I suppose that this sufficiently puts them in jeopardy. Clarke questions if they should believe Murphy and then brings up the scant supplies they have left, suggesting that they have to hunt. Bellamy questions if this is a good idea because of the Grounder army but Clarke makes it clear that they cannot defend themselves if they are hungry. Later, Bellamy organizes a hunting party and makes it clear that the bullets are for Grounders only and that the 100 are to use spears for hunting. He orders that they are all to return before it gets dark. Finn asks Clarke to go with him and she turns him down but Finn invites himself along, as Raven of course sends him pained looks. Raven returns to her tent to pack supplies but Bellamy tells her that she is not leaving. Raven points out that on the Arc, Bellamy was a janitor. Bellamy points out that it's too dangerous to go alone and asks Raven what else she has in her head. Raven brings up building radios so that the 100 can talk to each other. Bellamy says that they need her because she is smart.
On the Arc, Cain continues to look for survivors. Cain come across a survivor named Wood, who informs him of a hull breech in engineering. The two start walking, looking for more survivors and Cain comments that it's like they are on a ghost ship. They come across a group of people.
Back on earth, Miles, Finn and Octavia find themselves following suspicious tracks. Miles is shot with arrows, (yep, I knew Miles was the red shirt of that little team) so Clarke and Finn decide to leave him but they don't get far before the are knocked unconscious by Anya and a group of Grounders.
On the Arc, Cain realises that the temperature is dropping and says that it must be a message that they are being monitored. He is however told by Wood that he must have hypoxia. Cain says that they have to get moving now.
On earth, Clarke ad Fin are marched into a holding area. Finn whispers that he knows where they are because he tracked their distance along with memorizing markers. Clarke suggests that this doesn't matter because they weren't blindfolded because the Grounders didn't care what they saw. Clarke believes that they are going to be killed. Anya joins them and uses her sword to free Clarke. It seems that one of them is sick and so Clarke is ordered to make her better.
Cain and the rest of the survivors come to a collapsed area. Wood uses a communications device to contact the earth monitoring station and discover that Jaha survived. Cain reports that he has one dozen survivors with him. Jaha tells Cain to lead his people to the mess hall because Sinclair is re-rooting power and heat there. Cain agrees to do so only after he gets Jaha but Jaha says that fire burned through most of the oxygen in his section and all access to it is blocked off. How many times is Jaha going to play the role of brave hero by offering to die? Cain tells Jaha that he is not going to let Jaha die but Jaha orders him to gather as many survivors as he can. Cain decides to go on a one man rescue mission and orders the rest of the survivors to the mess hall. Instead of leaving Cain behind, the other survivors work with him to free Jaha. Exactly why are the survivors interested in saving Jaha when it has been revealed that all he has done is lie to them? I think I would have left him there.
