In their search for another segment of the Key to Time, the Fourth Doctor and Romana have to face the suspicion of the Lagoon dwellers, the stupidity of the technicians and, finally the powerof Kroll …

  • Rohm-Dutt (whose name is written as Rohm Dutt throughout) has a dream of being pursued by the Swampies and attacked by Kroll.
  • There is no mention of the Sons of Earth wanting to go back to Earth, just stopping human colonists expanding to Delta Three.
  • Dugeen confirms he is a member of the Sons of Earth, sent to sabotage the Refinery. His reaction to Thawns’s crack about them being a crank organisation is more angry than the televised version.
  • The Swampie killed by Kroll in the marshes is trying to get on The Doctor and Romana’s boat rather than on the bank.
  • The Swampies make no effort to save Ranquin from Kroll’s tentacle and leave the refinery after The Doctor stops the launch.
