Meanwhile, as Red Dwarf nears an ocean moon, Kryten receives a message from a woman on board an escape pod in orbit which is cut off.
Looking into the escape pod logs, Kryten reveals that Barker was a computer specialist whilst Green was the mission director, and both were married but not to each other.
Barker however convinces Green to give her access into the karma drive mainframe so that she could reprogram it for one night, thereby rewarding the unethical and punishing good behaviour.
Due to Barker's attempt at warning the crew, she and Green were vaporized, as their tampering led the karma drive to have its influence stretch past even the ocean moon and to everything in its vicinity.
As Lister laments at how two people's love brought down an entire ship, the crew decide to head back to Red Dwarf as unethically as they can.
The flashbacks on board the Samsara pre-accident involve none of the core crew, a rare occurrence in the series that has only occurred twice previously, in The Inquisitor and The Beginning, respectively.
