( September 2020 ) ( Learn how and when to remove this message ) On Bardo, Echo, Hope, Gabriel, Octavia and Diyoza are revealed to have been pretending to be on the Disciples' side while secretly plotting against them. Cadogan shows Gabriel, Niylah and Jordan logs left behind by the native Bardoans describing the same effect that Becca had experienced when she entered the final code into the anomaly stone; the logs mention a last war and achieving transcendence, the source of the Disciples belief system. However, upon closer examination, Jordan believes that the language has been mistranslated and it is a test to determine the fate of the human race, not a war. The Disciples need the Flame to reach this test, believing it to be in Clarke's head due to Octavia's memory of Clarke using the Flame to destroy A.L.I.E. Cadogan attempts to convince Gabriel that winning this perceived war will lead to a permanent peace as Echo attempts to release the Gem-9 bioweapon to wipe out the Disciples in revenge for Bellamy's apparent death. Though Echo is talked down, Hope kills Anders and attempts to release it herself; Diyoza sacrifices herself to stop the attempted genocide and to save her daughter and friends. On Sanctum, Sheidheda works to solidify his position, revealing his resurrection to Wonkru and defeating Indra in combat for leadership of the clan, though Madi manages to blind the Dark Commander in one eye. Hunted by Sheidheda and Wonkru, Murphy rallies the massacre survivors under his leadership to hide out and prepare to fight back against the Dark Commander's reign.
