Deviations from the original novel[]

  • No reference is made to the Scientifica using slave labour.
  • In the novel, the Doctor is unsure about how he was born, whereas in the audio he states that he was "unambiguously" Loom-born.
  • When the Fifth and Seventh Doctors are discussing past multi-Doctor events, they omit reference to how the Terrible Zodin used mind-rubbers, but mention the Knights of Velyshaa, (AUDIO: The Sirens of Time) which hasn't happened for the Fifth Doctor yet, and how their recent equations will be helpful when all thirteen Doctors have to work together to save Gallifrey. (TV: The Day of the Doctor) They also make reference to having "shorted out the time differential", (TV: Time Crash) the Fifth Doctor asking if he sounds older.
  • Where the novel ended with Roz knocking out the Fifth Doctor and the Seventh, Roz, and Chris departing for their TARDIS via transmat, the audio story adds an extra few moments where Adric, Nyssa and Tegan arrive while debating why the future Doctor doesn't recall these events only to find the Fifth Doctor unconscious.
