The Five Companions (audio story)

The Five Companions was Big Finish Productions' subscriber-free release for 2011.

Publisher's summary
Inside a cluster of fused-together derelict spaceships, four of the Doctor's oldest friends - and one of his newest ones - are lost and confused. They don't know how they got there or what they're meant to be doing - but as the place is infested with Daleks, Sontarans and dinosaurs, their first priority is staying alive.

To their collective relief, the Doctor turns up and has a reasonable idea of what's going on. If the six of them work together, they can escape this place and get home. But, unexpectedly, others may be working together to ensure they all die here...

Plot
to be added

Cast

 * Fifth Doctor - Peter Davison
 * Ian Chesterton - William Russell
 * Steven Taylor - Peter Purves
 * Sara Kingdom - Jean Marsh
 * Polly Wright - Anneke Wills
 * Nyssa - Sarah Sutton
 * The Daleks - Nicholas Briggs
 * The Sontarans - Dan Starkey

Culture

 * When the Doctor mentions to Polly that he is attempting to get into contact with the Capitol, she mistakenly believes that he is referring to the record label of the same name. He informs her that it is actually the seat of the Time Lords' power on Gallifrey.

The Doctor

 * The Doctor tells Polly that he tended not to refer to himself as a Time Lord during his first and second incarnations as he was on the run from his people.

Individuals

 * Of the eponymous five companions, Nyssa is the only one who never travelled with the First Doctor.
 * Before being returned to their proper places in history, the five companions all accept that the Doctor will not be able to keep his promise to check up on them and that they will very likely never see him again.

Species

 * Steven encountered the Sontarans when one of their scout ships crashed on the Elders' planet several years earlier in his personal timeline. This experience taught him that a Sontaran could be incapacitated by striking their probic vent.
 * A Tyrannosaurus rex is transported to the alternative Death Zone, where it kills several Daleks before it is exterminated.

Continuity

 * This audio takes place during the events of TV: The Five Doctors. The Fifth Doctor is diverted to an alternative Death Zone after using 's transmat recall device and discovers that some of his other companions have ended up there as well.
 * Ian and Steven previously met in the Mechanoid City on Mechanus in the 23rd century. (TV: The Chase)
 * Ian sets a trap for a Dalek by placing a sheet of metal on the floor in the hopes of disrupting the static electricity supply by which they are powered and subsequently disguises himself as a Dalek. He did both of these in his first encounter with them on Skaro. (TV: The Daleks)
 * Ian, Steven, Sara, Polly and Nyssa have all previously encountered the Daleks. (TV: The Daleks, TV: The Dalek Invasion of Earth, TV: The Chase, TV: The Daleks' Master Plan, TV: The Power of the Daleks, AUDIO: The Mutant Phase, AUDIO: Renaissance of the Daleks, AUDIO: Plague of the Daleks, AUDIO: The Elite)
 * The Sontarans have records of all the Doctor's incarnations. They recognise the Fifth Doctor from their encounter with him on Samur. (AUDIO: Heroes of Sontar)
 * The Doctor initially believes that he and his former companions are trapped in an artificial construct which has been created by the Master. (TV: The Five Doctors)
 * Nyssa would later encounter the Fifth Doctor in her mind shortly before his regeneration into the Sixth Doctor. (AUDIO: Winter) Later still in her personal timeline, she would meet the Fourth Doctor in 3488 (PROSE: Asylum) and subsequently rejoin the Fifth Doctor as one of his companions (AUDIO: Cobwebs). From the Doctor's perspective, both of these events have already happened.
 * This is the Doctor's first encounter with each of his first incarnation's companions since they left the TARDIS. (TV: The Chase, TV: The Daleks' Master Plan, TV: The Savages, TV: The Faceless Ones) None of them know that the Doctor is a Time Lord nor are they familiar with the concept of regeneration. Even Polly, who witnessed the Doctor's regeneration into his second incarnation, remains uncertain of the process. (TV: The Tenth Planet)
 * The Doctor tells Ian that he had intended to visit him several months earlier. This is a reference to the original plans for TV: Mawdryn Undead, which had envisaged Ian taking the part ultimately allocated to Brigadier Lethbridge-Stewart.
 * Ian has come out of retirement to take up teaching again and is married to Barbara Wright. Polly is married to Ben Jackson. She comments that the Doctor never thought that they would last as a couple. This would appear to contradict PROSE: Mondas Passing, in which they are said to have each married other people, as well as AUDIO: The Forbidden Time, in which Polly states that they saw each other only occasionally.
 * Polly claims sarcastically that making coffee was usually her main contribution to the proceedings. (TV: The Tenth Planet, TV: The Moonbase, AUDIO: The Selachian Gambit)
 * The Doctor refers to Polly challenging the Cyber-Leader Krail in the Snowcap in December 1986 (TV: The Tenth Planet) and destroying a squadron of Cybermen on the Moonbase in 2070 (TV: The Moonbase).
 * Commander Skaal refers to the Sontaran invasion of Gallifrey. (TV: The Invasion of Time)
 * The Doctor tells his former companions that, after being returned to their respective native eras by the Time Lords, their memories of their experiences in the alternative Death Zone may be hazy. This could account for the fact that Sarah Jane Smith did not remember the events of TV: The Five Doctors when she was reunited with the Doctor, then in his tenth incarnation, in TV: School Reunion.
 * The fact that Ian is an elderly man would seem to disprove the rumour, as related by Sarah Jane to her friends Clyde Langer and Rani Chandra in 2010, that he and Barbara have not aged since the 1960s. (TV: Death of the Doctor)
