Parallel world (Turn Left)
Donna's World is a rewritten version of the official timeline created when Donna Noble turned right instead of left while deciding which of two different job interviews to attend. It is not actually a parallel world since the walls between realities were sealed in Doomsday. This was made explicit by the production team.
- This name is conjectural and is not is actually used by any of the characters.
Origin
While on Shan Shen, Donna Noble was unknowingly fitted with a time beetle, part of the Trickster's Brigade. A fortune teller selected a point in her life where making seemingly random choice had enormous ramifications.
In June 2007 Donna had to make a choice between two jobs. The moment she chose between the jobs was at a junction. Her agency had offered her a contract with H.C. Clements, which while temporary, was posh and in the centre of London, which Donna enjoyed. Her mother, Sylvia Noble, had managed to get her another job opportunity to become the personal secretary of Jival Chowdry, owner of a photocopying business. Although this would be a permanent job, Donna found it less interesting.
While driving and in discussing the dilemma, Sylvia pressured her into turning right to stop by Jival Chowdry for a chat. While in the regular timeline Donna ignored her mother and turned left, in this timeline she turned right, resulting in her taking the PA job.
Alternate Timeline
December 2007: The Doctor tracks down the Empress of the Racnoss to the Torchwood base underneath the Thames Barrier and blows it up, which floods the whole thing. Although the Empress of the Racnoss and her offspring drown, the Doctor is unable to escape and dies too quickly to regenerate. The TARDIS is salvaged from under the Thames and sent to a UNIT base in Leeds.
In the original timeline, the Doctor met Donna Noble who saved his life when she told him to stop after the Doctor blows up the Torchwood base.
April 2008: The Judoon H2O Scoop the Royal Hope Hospital to the Moon to find a Plasmavore criminal and her Slab accomplices. Although they found and killed the alien criminals, the Plasmavore had already armed the MRI. Sarah Jane Smith, Luke Smith, Maria Jackson, and Clyde Langer managed to disarm it but died along with the rest of the hospital when the oxygen ran out. The only survivor was Oliver Morgenstern who was passed the last oxygen tank by Martha Jones, who died.
In the original timeline, the Doctor investigates the hospital instead of Sarah Jane, Luke, Maria and Clyde under the alias "Mr Smith" and no-one suffocates because he found the Plasmavore in time. Shortly after, he took on Martha Jones as a companion.
In this timeline, the Saxon regime never started because the Doctor, Martha and Jack never went to the End of the Universe to remind Professor Yana that he was the Master. It is unknown what happened to Richard Lazarus as Mr Saxon was never able to finance his experiment as in the original timeline. It appears that, because the Master/Mr Saxon wasn't around in the 21st century, the Archangel Network or the Valiant were never designed or built. President-Elect Winters would also appear to survive, as would Vivien Rook.
December 2008: A replica of the RMS Titanic crash-lands onto Buckingham Palace, which destroys the Greater London Area and floods the whole of Southern England with nuclear radiation. Astrid Peth, Mr Copper, Midshipman Frame, and the Royal Family all die.
In the original timeline, this crisis was averted thanks to the Doctor. Although the city was nearly abondoned in the main timeline, this seems not to be the case here.
2009: The United States promises fifty billion pounds in financial help for Great Britain but this plan has to be abandoned when sixty million Americans were fully converted into Adipose children. This arguably marks the fall of the United States. Miss Foster's plan is not only successful, but sixty times as successful as was planned in the real world.
In the original timeline, the plan was stopped before it was put in full swing thanks to the Doctor and Donna Noble. The change in location was probably due to the crisis in South England.
2009: The Sontarans activate the ATMOS devices in the cars to convert Earth into a breeding ground. Although Jack Harkness is stranded on Sontar, Gwen Cooper and Ianto Jones give their lives to revert the atmosphere to its previous state and destroy the Sontaran flagship. Britain is largely unaffected due to its poverty and hence its lack of ATMOS devices. Much more deaths occur across the world as the pollution continues into the night. This is possibly due to the fact the Valiant is never built, which helps turn the tide against the Sontarans in the original timeline.
In the original timeline, the Sontaran invasion of Earth was prevented by the Doctor, Donna, Martha Jones and UNIT. The Doctor was able to clear the atmosphere without the assistance (or sacrifice) of any Torchwood members (though The Stolen Earth hints that they had some role in these events as they know of Sontarans.)
Negation
UNIT and Rose Tyler sent Donna back to the time where the worlds split. To make her past self turn left, she headed from her landing location to the road where her past self was in her car. Running out of time, Donna jumped out in front of a lorry. Although she died, a traffic jam quickly blocked the route right from the past Donna, so the past Donna chose to turn left. (DW: Turn Left) Donna's world was presumably negated.
