When "Starbug" arrives at Delta VII, it turns out that the planet has been destroyed in order to deal with a massive Epideme outbreak – a fact that the virus was fully aware of, and used in its attempt to prevent Lister from killing himself. With Lister on the verge of death, Kochanski injects Lister with a drug that stops his heart, then gets his corpse to bite her left hand, infecting it. After amputating her left arm she reveals that it was actually Caroline Carmen's arm, and that her own left arm is intact. Kryten and Kochanski then revive the now virus-free but now one-armed Lister.
