Efter at have fundet Abby bevidstløs, begynder Clarke og Madi at arbejde på at genoplive hende. Clarke får hende til at kaste op for at reducere opiatforgiftningen og derved få hende til at genvinde bevidstheden. Netop da kommer McCreary ind i lokalet og undrer sig over, hvordan Clarke og Madi kom ind uden at blive opdaget af "øjet". Uden tøven afslører Clarke, at Wonkru arbejdede sammen med Raven og Echo for at slukke for satellitkameraet og erstatte dets feed med en videosløjfe . Clarke og McCreary indgår en aftale med ham om at lade hende og Madi blive, så længe Clarke får Abby på benene for at behandle McCreary og hans folk.

Madi konfronterer Clarke for at have forrådt Octavia og Wonkru til McCreary, men Clarke insisterer på, at det er den eneste måde at holde hende og Madi i live. Madi er uenig og argumenterer for, at de ikke ville være i stand til at leve med sig selv. Efter at have vågnet og hørt Clarkes plan, er Abby også imod det. Hun fortæller Clarke, at McCreary er en frygtelig, farlig person. Men Clarke insisterer på, at hun og McCreary skal arbejde sammen, fordi de begge ønsker det samme - at stoppe Octavia . Da Clarke arbejder på opiater -detox -processen for Abby, siger Abby, at hun ikke er værd at spare. Hun begynder at fortælle dem, hvad der virkelig skete i bunkeren i løbet af det mørke år.

Det var efter at have været nede i bunkeren i to år, at Wonkru løb tør for proteintilførsel (sojabønner) på grund af en svampeinfektion i hydrofarm. Under et møde med Octavia, Indra , Kane og Abby, Kara Cooperinformerede dem om, at svampen spredte sig til flere afgrøder. Hun sagde, at hun havde formået at redde et par sunde frø, men det ville tage mindst et år at udrydde de inficerede afgrøder og plante de nye frø for at producere proteiner. Abby informerede om, at et år uden proteinkilde ville skade deres helbred meget. Hun fortalte dem, at der kun var ét svar - ty til kannibalisme. Hun foreslog, at den eneste måde, de kunne overleve på, var, hvis de begyndte at spise de mennesker, der døde i gruben. Octavia kunne ikke lide ideen, men Abby insisterede på, at det var den eneste måde. Så Octavia gav efter for at redde sit folk fra at sulte.

Octavia forklarede derefter madsituationen til Wonkru. Hun fortalte dem, at selvom de måske synes, det er synd at spise menneskekød, ville den største synd være at lade sig sulte ihjel, når de ved, at det er alt, der er tilbage af menneskeheden. Indra tilføjede, at dem, der kæmpede i arenaen, døde, så resten kunne leve. Deres offer skal ikke gå til spilde. For at gå foran med et godt eksempel tog Octavia smerteligt den første bid og opfordrede de andre til at gøre det også. Nogle accepterede, mens andre, herunder Kane, nægtede at spise menneskekød. Den eneste måde, hvorpå dette kan fungere, er, hvis alle deltog. Så Abby rådede Octavia om, at hun skulle gøre det til en forbrydelse for folk, der ikke spiste. Og det betyder at dræbe alle, der nægter at spise. Octavia hadede planen, men Abby pressede hende til at gøre det.

Efter Abbys råd kom Octavia ind til det næste måltid med en pistol og gik rundt i lokalet og tvang folk til at spise. Hun begyndte at overtale dem til at spise, fordi hun ikke ville dræbe dem. Men uden valg blev hun tvunget til at begynde at skyde dem på stedet. Dette fik Kane til at stoppe oprøret og også begynde at spise menneskekød. Octavia hadede, at hun var nødt til at gøre dette og bære hele byrden selv. Det var det, der gjorde Octavia til mørket, Blodreina.

After revealing this to Clarke and Madi, Abby starts crying, admitting that it was her fault. She feels responsible for what Octavia has become. This gives Madi confidence to try and end the war by killing McCreary. Clarke stops her. Madi and Clarke argue and Madi still defends Octavia’s actions. She tells Clarke that Octavia did what she had to do to save her people. Octavia bore the burden so that her people didn't have to - just like Clarke did at Mount Weather. Clarke is shocked that Madi knows about Mount Weather. Madi then calls out Clarke for lying about Bellamy, Raven, Octavia and even Murphy for always being the heroes in the stories when all along it was Clarke who was the hero, until now. Madi says she’s ashamed of her because of what she’s doing now, not fighting. Clarke explains that she did those things in the past to pretect her people but now that Madi is part of her people she will do anything to protect her (even helping to heal McCreary.) Clarke expresses that she never called herself a hero to Madi because she isn’t one and then walks away to go back to helping Abby treat McCreary and his people.

Meanwhile, Raven, John, Emori and Echo are hiding in a cave with Shaw, Diyoza and Kane. They notice that McCreary has called off his people from hunting them and is moving them to strategic positions. They realize that McCreary knows Wonkru is coming. They figure out that Clarke must have betrayed them to McCreary. So, they radio Bellamy to warn Wonkru that all the entrances into the valley are now blocked. However, Bellamy says they don't have a choice because they are already on their way and don't have enough food rations left to return to Polis. So, Echo promises to think of a way for them to get in. Indra and Bellamy tell Octavia about the situation. Bellamy angrily blames Octavia for leading them to a death trap after burning down the hydrofarm back in Polis.

To figure out a way for Wonkru to enter safely, Spacekru leaves the cave and starts scanning the area. Raven urges Shaw to remain behind so that he doesn't get captured and tortured by McCreary to launch the missiles. After noticing McCreary's ammunitions, Murphy suggests stealing it, leaving McCreary without weapons. Unfortunately, they're confronted by McCreary's people with more deadly weapons. Just before Spacekru surrenders, Shaw shows up and gives himself up. He tells McCreary's people that they would probably get a big reward if they take him because he's more valuable to McCreary than Spacekru. They are convinced and let down their guard. Shaw grabs the opportunity to attack them, knocking them down within seconds. Spacekru then jumps in to help Shaw in the fight. After that, Echo is impressed by Shaw's combat skills. But Raven seems disappointed. Later in the cave, Raven reveals that she was only mad because Shaw risked his life and made her worry about him. They share a passionate kiss.

As Spacekru explains what they observed, Diyoza figures out that McCreary is using the battle plan she wrote. She tells them that it was very thorough and no loopholes. However, she says that she has a plan. So, Echo calls Bellamy and Indra to tell them about the plan. Before telling Octavia Echo's plan, Bellamy makes Octavia promise that she would be willing to share the valley with the prisoners if they surrendered. Otherwise, there would be a lot of body count on both sides. Octavia says that she wants the same thing too. She just wishes it was possible without a war. As they get closer to the valley, Wonkru sets up tents for most of the people to stay there while just a few march into the valley. Bellamy says goodbye to Monty and marches to the valley with Octavia, Indra and a couple other warriors.

Lige før Wonkru ankommer, overgiver Diyoza og Kane sig til McCreary. McCreary stoler dog ikke på dem. Diyoza fortæller ham, at hun ved, at han bruger hendes kampplan, og de har brugt et smuthul i den til at fortælle Wonkru, hvordan man kommer inde i dalen. Hun tilbyder at hjælpe ham med at stoppe Wonkru, hvis han lader hende og Kane tilbage. Kane begrunder sin position med at sige, at han aldrig ville lade djævelen (Octavia) inde i dalen.
