Complete story — includes the ending
In Polis, a conclave is held to decide the new Commander. Ontari, former bodyguard of Queen Nia, arrives and murders the other Nightbloods, declaring herself Commander. Titus names Clarke the new Flamekeeper and she takes the A.L.I.E. 2.0 computer chip, known to the grounders as "the Flame", to find Luna, a Nightblood friend of Lincoln. Titus kills himself to ensure Ontari cannot use him against Clarke, and Ontari swears Roan and Murphy to secrecy about the missing Flame. Bellamy goes to Octavia for help to save Kane, Lincoln, and Sinclair from execution, but is captured by Octavia and Indra. Abby, Octavia, Miller, and Harper stage an elaborate rescue, with last-minute help from Monty, whose betrayal of Pike is covered up by his mother. When Pike threatens to execute the interned grounders, Lincoln surrenders to save them, while the others escape Arkadia. Octavia watches from a distance as Pike executes Lincoln.
