Complete story — includes the ending
After arriving on Bardo, Octavia's memories are scanned by Levitt, a compassionate Disciple scientist who takes an interest in Octavia. Hope eventually arrives and rescues Octavia with Levitt's help, returning her to Sanctum which causes Octavia to lose her memory of her time away. Captured in an attempt to rescue her mother, Hope reluctantly helps Anders return Octavia to Bardo for further interrogation. After Octavia pulls Hope through the anomaly to Sanctum, Hope injects her with a locator tag which sends Octavia back to Bardo. When Bellamy arrives, he overpowers his captors and attempts to save his sister, however a Disciple sets off an explosion, apparently killing Bellamy who vanishes. In the present, Echo, Hope and Gabriel arrive on Bardo, learning from one of Anders' sermons that the Disciples came to Bardo through the anomaly rather than Eligius III. They rescue Octavia, but learn of Bellamy's apparent death. On Sanctum, Russell's followers attempt to force his release with Murphy's attempt to help as Daniel Prime putting his life into danger. Sheidheda talks the Faithful down, but his behavior causes Indra to realize his true identity. Unable to kill Sheidheda just yet, Indra has Russell's mind drive surgically removed by Jackson so that the Dark Commander can't ever be resurrected again.
