“Hesperides” was split between two arcs: Hope and Co. attempting to escape Penance, and Clarke and Co. trying to find Penance and reunite with their friends.
Spoilers ahead for the June 10 episode of The 100 Season 7, called “Hesperides.”
In fact, I would argue that The 100 needs to kill off a major character.
By the end of the hour, no fewer than nine notable characters joined Bellamy, Octavia, and Diyoza in uncertain fates and possible death.
