Complete story — includes the ending
With little sense of the situation outside of the bunker, Clarke and Jaha refuse to open the door and risk the future of humanity. Abby helps Bellamy unlock the door and Clarke is unable to use force to stop him from opening it. Echo is stopped from exposing Skaikru's treachery when Octavia threatens to reveal her cheating and banishment. Octavia bans Echo from the bunker. By Octavia's decision, Clarke is left with 12 hours to banish over 300 of her people to the surface, possibly leaving too few skilled workers to maintain the bunker. At Arkadia, Monty tries to save the others to no avail. The partygoers commit mass suicide using a fatal overdose of the hallucinogenic Jobi Nuts previously encountered by the 100 shortly after their landing on Earth, Jasper dying in a devastated Monty's arms. However, Harper decides that she loves Monty enough to live. At the same time, a rapidly-deteriorating Raven is convinced to undergo a suicidal spacewalk by her hallucination of Becca before a hallucination of Sinclair appears to give her new hope. With Sinclair's help, Raven purges A.L.I.E.'s residual code from her brain by temporarily killing herself, "rebooting" her brain and curing her condition.
