Echo is probably feeling pretty pleased with herself, having apparently had Skaikru's shady intentions right all along. Of course, none of this will matter if Azgeda doesn't win the conclave — they'll all die in the praimfiya.
Kane's been something of a father figure to both Bellamy and Octavia. He doesn't look too thrilled to see Octavia readying herself to fight in the conclave either.
Luna is taking part in the conclave, which is strange because she's an outspoken pacifist. I guess the end of the world changes priorities for some people.
