Complete story — includes the ending

With the grounders' deadline imminent, Abby and Jaha disagree over what the survivors are to do; Jaha wishes to evacuate to the so called "City of Light", while Abby wants to remain behind to rescue the 47. Clarke, Octavia, and Bellamy hold the reaper-state Lincoln in the drop ship and learn he was drugged and experimented on. Lincoln's heart stops but is restarted by Clarke, who believes there is a way to cure reapers – information they can use with the grounders. When Abby cures Lincoln, Lexa grants Clarke the truce but demands Finn's execution for the massacre before it can begin. In Mount Weather, Jasper, Monty, Miller and Harper discover that there are Ark survivors on the ground. Dr. Tsing learns that for the mountain residents to live on the surface, they would have to kill the 47 for their bone marrow. Though Wallace vetoes the plan, his son Cage goes behind his back and begins the process with Harper.
