An inquiry begins regarding the timeonic fusion weapon, President Romana’s unorthodox measures to locate and retrieve it, and her apparent inability to do so – or even, for that matter, to prove that it ever existed. But curiously, the Matrix, the repository of all Gallifreyan knowledge, seems to differ with the established record – a visual document exists of the weapon being created, and even test detonated, by the Time Lords themselves. Cardinal Braxiatel admits that research was carried out, in which he himself participated, but no test of the weapon ever occurred. When Romana digs deeper to find out why the Matrix records conflict with his account, a computer virus is unleashed which Romana’s K9 is barely able to contain – and if he fails, or his batteries run out, that virus will lay waste to Gallifrey’s computer-dependent society. And while she is trying to eavesdrop on Romana’s behalf, Leela discovers how her husband Andred died…and who killed him.
Cast: Lalla Ward (President Romana), Louise Jameson (Leela), John Leeson (K9), Miles Richardson (Cardinal Braxiatel), Sean Carlsen (Coordinator Narvin), Andy Coleman (Commander Torvald), Lynda Bellingham (Inquisitor Darkel), Daniel Hogarth (Glower), Trevor Littledale (Archivist), Stephen Mansfield (Glower’s Technician)
Notes: This story establishes that the test-firing of the timeonic fusion device was responsible for the destruction of the planet Minyos. Minyos – and a vague backstory about its destruction being caused by the Time Lords – was established in the fourth Doctor story Underworld, which also showed that the Time Lords made reparations to the few surviving Minyans by giving them a variant of Time Lord regeneration ability that made them effectively immortal. That same story also featured Leela, though she seems not to recall the Doctor’s encounter with the survivors of Minyos here.
