Things aren’t going well at Arkadia, as usual. They aren’t able to find and preserve enough food to store on the Ark for when the radiation comes, and they won’t be able to grow their own protein without a hydro generator. Raven takes a verbal shot at Bellamy for choosing to save people over the generator, but he tells her that he’s going to sacrifice himself anyway, so nothing she says is going to hurt him now. Raven turns to Clarke instead, to nag her about making a new list of 100 people, this time the ones who’ll get to be in the Ark on Doomsday. I love Raven, but she gets kind of stubborn, mean and single-minded when she’s in a bad mood. And she’s definitely in a bad mood this season.
The discussion is interrupted when Nyko, Luna and some of her people arrive at Arkadia suffering from Acute Radiation Sickness. They are looking for medical help from Skaikru. Luna has the grace to acknowledge that Skaikru has good reason to turn her away, and to beg them not to. Abby would never turn away anyone in need of medical help, and this group includes children, so they’re brought right in to the med bay. They tell Skaikru that all of Luna’s people are dead except the ones they’ve brought here, and the fish throughout the ocean are dying, as well. After Jackson examines the patients, he determines that the radiation sickness is from eating radioactive fish, rather than airborne radiation.
