With factions vying for control of the ship, the Vervoids are found to be responsible for the many disappearances. Only the Doctor sees the fundamental but missed point as to why they can't be reasoned with or why they can't be allowed to arrive on Earth.

While Mel and Ace run from Glitz's former crewmen (whom he sold to Kane), officers Belazs and Kracauer conspire to overthrow Kane. The Doctor, meanwhile, discovers there really is a dragon in the ice caverns, which turns out to be a bio-mechanoid with a very interesting function.
