Terror of the Vervoids (TV story)

This was the Doctor's evidence at the Trial of a Time Lord.

Synopsis
The distraught Doctor gives the court his evidence for the defence. He chooses an incident from his own future, in which he and his companion Mel arrive on the space liner Hyperion III in response to a distress call. There they battle against and ultimately destroy a hostile race of alien plants, the Vervoids, while also helping to thwart a mutiny by the ship's security officer, Rudge.

The Doctor, still angered by what happened to Peri, presents his case, and must fight to prove his inocence.

Individuals

 * Melanie Bush comes from Pease Pottage, and has almost total recall. Her house had a large garden, with a compost heap.
 * Travers and Hallett have both met The Doctor on a previous occasion.

Planets

 * Mogar is a planet in the Perseus Arm of the Milky Way. It is rich in rare metals (including vionesium, similar to magnesium, which emits light and carbon dioxide when exposed to air and thus ignited), which are being exploitatively mined by humans, it is the home planet of the Mogarians.
 * Between Mogar and Earth lies the Black hole of Tartarus.
 * Stella Stora suffered from grain shortages around 2983.

Races and Species

 * Vervoids were created on Mogar by Lasky to be a workforce to replace robots.
 * Mogarians are gold skinned humanoids with grill like mouths who cannot breathe oxygen. They are a peace loving race, for whom water on the face is fatal, but who nevertheless drink tea.
 * Vervoids can produce a gas that smells like methane, but is non-explosive, in large enough quantities to kill humans.

Story Notes

 * This is the first appearance of Bonnie Langford as Mel, who receives no introductory story, and indeed no explanation of how she came to travel with the Doctor.
 * Working titles for this story include: The Ultimate Foe and The Vervoids.
 * This story was a replacement for an original submission, "Attack From the Mind" by Jack Trevor Story, set on the planet Penelope; later drafts included "The Last Adventure" by Christopher H. Bidmead and "Paradise Five" by P.J. Hammond.
 * Honor Blackman (Professor Lasky) is best known for playing Cathy Gale in The Avengers and as Pussy Galore in the James Bond film Goldfinger.
 * Lasky is reading Murder on the Orient Express in the lounge.

Discontinuity, Plot Holes, Errors

 * Lasky has been into room 6, not finding her luggage there, because her key is actually for room 9. So how did she get in?
 * How did Grenville know that the unidentified craft on the Hyperion's scanner was the TARDIS? The Doctor states the message was sent directly to him.
 * Why don't the Mogarians notice a major change in character in one of their number? Why would the Mogarians necessarily know each other? The Hyperion III is a passenger liner.
 * If the Vervoids are genetically engineered, why create them with lethal stings? Doland seems unaware of the existence of the stinger; he shakes hands with a Vervoid. It may have been an unintended consequence.
 * Why does the Captain state that the ship is hijack-proof, even though it has been hijacked by Brookner? Between the ease with which the door lock is cut, and the fact that the Vervoids have no trouble gassing Brookner, "hijack-proof" seems to be an exaggeration.
 * The Vervoids wear tracksuits and trainers (wilting and climbing through the tunnel in the final part).
 * Since the Doctor is shown viewing an event in his future, presumably he should already know what's going to happen once his personal timeline catches up to the Vervoid incident. Yet he appears totally unaware as he proceeds through the adventure. It can be speculated that the Doctor likely erased his memory of the event so as not to corrupt the timeline later. Evidence in support comes from the 2007 special Time Crash, in which it is strongly suggested that the Tenth Doctor only remembers meeting himself (from his Fifth life) upon hearing the cloister bell.

Continuity

 * Mel meets the Doctor for the 'first time' in PDA: Business Unusual.
 * PDA: Instruments of Darkness reveals some information about the Doctor's previous adventure with Travers.
