This week, matters on the Ark become even more dramatic, and things on the ground change as Raven successfully makes her landing. Yes, matters on the Ark had been ruining the flow of surface matters, as it was never as fast-paced and engrossing as the ground. However this week, things start to get serious on the Ark.
Meanwhile, on the Ark, it is discovered that the oxygen supply has greatly depleted from the projected amount, and so, whilst Abby was in confinement, the council met to agree to cull 300 people. Abby is brought in by Jaha to help those suffering because of the lack of oxygen, one of whom is a nine year old girl who is going blind.
To try and stop the culling, Abby decides to release her husband’s video and tell people about the plan. This inspires the people to sacrifice themselves to save their loved ones. Jaha is persuaded by Kane not to join the volunteers. When the flairs are seen, it is too late as the volunteers have already been gassed.
