After experiencing a hallucination of Roan and the real Echo, Echo kills three of them. With the anomaly closing, Gabriel, Echo and Hope choose to follow the others through it to find Bellamy. With the various factions now living together in Sanctum, tensions rise, particularly with the Children of Gabriel demanding Russell’s execution while Murphy is guilt-stricken over his role in Abby’s death and Madi continues to experience memories from one or more of the Commanders. A depressed and suicidal Russell destroys Priya’s mind drive and goads Clarke into killing him; after Clarke knocks Russell unconscious, he is greeted by Sheidheda in the Mindspace who had uploaded himself into Russell’s mind drive when the Flame was destroyed.

Episodes 02

“The Garden”

Octavia arrives on Skyring three months after following Diyoza through the anomaly due to time dilation. With her arm fully healed, Octavia forms a family with Diyoza and Hope over the next ten years. For six years, Octavia attempts to return through the anomaly to Sanctum, but it is too deep underwater. Giving up, Octavia sends a message in a bottle to Bellamy through the anomaly and settles into life on Skyring. However, her message is intercepted by the Disciples on Bardo who capture Octavia and Diyoza, though Octavia manages to hide Hope from discovery. In the present, Hope, Gabriel and Echo arrive on Skyring centuries after Hope left, with Hope’s memory restored. The three attempt to follow the Disciples to Bardo, but they discover the code has washed away from Hope’s note. Stranded, the group discovers that the Disciples turned it into a prison planet for the weak and will return in five years. Gabriel discovers the body of Colin, an old friend of his, and he realizes that Skyring is in fact planet Beta from the Eligius III colony mission, suggesting that Bardo is another Eligius planet and that the Disciples are the descendants of other colonists that had settled there. Hope explains that she only injected Octavia with a locator tag to send her through the anomaly; a recording of Becca reveals that the time dilation is caused by proximity to a nearby black hole. Though Gabriel discovers the code on Colin’s Memory Drive, a prisoner named Orlando destroys his computer before they can record it for use.

“False Gods”

As his execution approaches, Sheidheda manipulates the situation so that killing him will create a martyr and cause the fanatics to destroy Sanctum, forcing Clarke to stop the execution. At the same time, while trying to fix Sanctum’s nuclear reactor, James Crockett accidentally triggers a nuclear meltdown with his carelessness and is killed in the process. After Gaia reveals the truth about the Flame, many in Wonkru abandon the cause, forcing Raven to turn to the Eligius prisoners for help. Hatch, a former bank robber, and three other prisoners volunteer alongside Murphy and Emori whose Nightblood offers them protection to fix the core itself. However, the radiation exposure proves fatal to the prisoners, forcing Raven to lie to them in order to get them to fix the cooling system in time. With the help of Murphy, Hatch is able to complete the job at the last possible second before dying from the radiation exposure.

Episodes 04

“Hesperides”

A few months after the kidnapping of Octavia and Diyoza, a Disciple prisoner named Dev arrives on Skyring, forming a bond with Hope. They plot to ambush the Disciples when they return in ten years in order to go through the anomaly to rescue Octavia and Diyoza. However, the plan goes wrong and Dev is killed, forcing Hope to continue on alone. In the present, Gabriel, Echo, and Hope are forced to wait for the Disciples’ return; they learn that the Disciples believe that there will be a last war and that they worship Eligius III as a deity that saved them from the Earth’s destruction.

On Sanctum, Sheidheda challenges Murphy to a game of chess, revealing that something terrible is about to happen and offering information if Murphy wins. This proves to be a distraction so that Emori won’t have Murphy’s support in her venture: she organizes a ceremony to reunite the Children of Gabriel with their families.

Nelson then joins the Eligius prisoners in taking over the gathering along with the Children of Gabriel and Nikki states that they need to make demands.

Two years later, Becca arrives from Polaris and using the Flame, is able to open the portal to Bardo; although Becca insists on using Nightblood to retake the surface instead, Cadogan is adamant about leaving. While bonding with Callie, Becca discovers the stone code leading to what she calls Judgment Day, the true end of the human race; Cadogan has her locked up for refusing to cooperate further and then burned at the stake to get the Flame. Informed of the AI’s significance by Becca, Callie steals back the Flame and leaves with people she has convinced to take Nightblood, bringing with them enough Nightblood to save 2,000 more people.

Episodes 10

“A Little Sacrifice”

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.

During their journey, Bellamy learns that the planet’s original inhabitants apparently transcended into beings of light and after a vision of his mother and Bill Cadogan, begins believing in the Disciple cause. Bellamy and Doucette travel for over two months together, surviving a massive winter storm and a hazardous climb in which Bellamy chooses to save Doucette rather than let him fall.

Nikki attempts to take revenge on Raven, but ultimately decides to leave Raven to live with what she has done. Indra and Sheidheda work together to escape; having learned the truth about her mother’s defection to Sheidheda’s side, Indra decides to leave the Dark Commander to die of his wounds rather than outright killing him. Gabriel begins using Eligius technology to repair the Flame, but changes his mind and destroys it forever instead. Taking control of the situation, Clarke kills Doucette and forces Cadogan to open the anomaly to their friends and travel through with Raven, Jackson, Madi, Emori, Indra and Murphy, but Sheidheda directs Bellamy to Madi’s sketchbook containing proof that she has the Commanders’ memories.
