Mysterious outsiders arrive with news of Clarke's missing people.
Tropes:
- Call-Back: Octavia knows multiple Classical Mythology stories like Hercules and Hesperides. She most likely learned these from Bellamy, who named her after Emperor Augustus' sister because he was into Greco-Roman history.
- Call to Agriculture: Echo is not having it at first, but does over time grow protective of her tomatoes.
- Expository Hairstyle Change: Echo and Hope get this after a 5 year time jump.
- Troubled Backstory Flashback: Hope gets this.
- Wounded Gazelle Gambit: Echo and Hope invoke this to get Orlando to cooperate with them, by having Hope pretend to drown so that he can save her.
