Where We Left Off: Clarke and Bellamy murdered all the Mountain Men, including Maya, by contaminating Mount Weather with outside air. Unable to face what she did, Clarke refused to return to Camp Jaha. On his quest to discover the City of Light, Jaha met an A.I. avatar with a nuclear warhead who says she's been waiting for him.
What's Next: The avatar shows Murphy and Jaha the City of Light, but it isn't exactly what Murphy expected. Clark finds herself reunited with Lexa, who is embroiled in a power struggle with the Ice Nation and their queen Nia (Brenda Strong). Kane and Abby want to team up with the other clans against the Ice Nation, but first they must deal with civil unrest led by a new Ark survivor Pike (Michael Beach). This season will also introduce Roan (Zach McGowan) a rogue Grounder who plays a crucial role in the clans' power struggles.
