UNTOLD ADVENTURES: GEMMA & SAMSON
According to THE COMPANY OF FRIENDS the Eighth Doctor travels with two companions, Samson & Gemma. They are in Vienna when the Doctor gets a distress signal from his older self, which leads into the events of MARY’S STORY…
MARY’S STORY #1
The events at the Villa Diodati from the point of view of the younger version of the Eighth Doctor.
At some point after his travels with Mary Shelley are over the Eighth Doctor returns to Vienna and picks up his companions Samson & Gemma. He then resumes his travels with them before they leave him prior to the events of STORM WARNING.
The Eighth Doctor tells Charley that he used to travel with Mary Shelley…
I didn’t hear anything to indicate when this story takes place. Since it was the first Eighth Doctor audio not to be part of the monthly Eighth Doctor releases, I’ve placed it in the Story Gap between MINUET IN HELL, the last release of ‘Series One’ and INVADERS FROM MARS, the first release of ‘Series Two’.
I didn’t hear anything to indicate when this story takes place. Since it isn’t a part of either of the first two series of Eighth Doctor stories, I’ve placed it after LIVING LEGEND.
THE LIGHT AT THE END
I didn’t hear anything to indicate when this story takes place for the Eighth Doctor and Charley but it must be before the arrival of C’rizz as he doesn’t get mentioned. So since it isn’t part of either of the first two series of Eighth Doctor stories, I’ve put it after LIVING LEGEND and SOLITAIRE, both of which were released first.
THE ELIXIR OF DOOM
The Doctor encounters Iris Wildthyme and Jo Grant in 1930’s Hollywood. He recognises Iris from their meeting in THE SCARLET EMPRESS, an example of one storytelling universe referencing another. This suggests that the adventures of the BBC Books Universe take place before the Doctor meets Charley Pollard in STORM WARNING.
THE FURTHER ADVENTURES OF LUCIE MILLER
Big Finish locate these stories after HUMAN RESOURCES.
THE FOUR DOCTORS
I didn’t hear anything to indicate when this adventure takes place for any of the Doctors. So for Eight I’ve placed it after his adventures with Lucie Miller.
The events of the Villa Diodati from the point of view of the older version of the Eighth Doctor. The TARDIS ‘regenerates’ at the end of this story possibly turning into the version used by The War Doctor in THE DAY OF THE DOCTOR.
THE LEGACY OF TIME: LIES IN RUINS The Doctor has a new companion, Ria. Since his next companion, Sheena, gets wiped from existence at the start of THE STARSHIP OF THESEUS, where new companion Bliss replaces her, Ria must have travelled with Eight before Sheena did.
DAWN OF THE DOCTOR
The Untold Adventure that takes place immediately after Paul McGann regenerates into John Hurt…
THE RETURN OF THE DOCTOR
The Untold Adventure that takes place immediately after John Hurt regenerates into Christopher Eccleston.
