Parallel world (Turn Left)

Donna is convinced to turn right, rather than left when she was supposed to.

Fortune Teller: "But was there ever a choice? This job of yours. What led you there?"

Donna Noble: "There was a choice. Six months before. Cos the agency offered me a contract with H.C. Clements..."

— Donna Noble and a Fortune Teller

Donna's World (a.k.a "Turn Right") was 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. As a result, the Doctor never met Donna and died underneath the Thames Barrier. He also never met Martha Jones. These events resulted in devastating effects for Earth and the universe.

This name is conjectural.

History

While on the planet Shan Shen, Donna 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. (DW: Turn Left)

Timeline

December 25, 2007

The Doctor is dead...

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. Donna stumbles across Rose Tyler, who has arrived on the scene too late to do anything. The Doctor's TARDIS is salvaged from under the Thames and sent to a UNIT base in Leeds. (DW: Turn Left)

In the original timeline, the Doctor met Donna Noble who saved his life when she told him to stop after the Doctor blew up the Torchwood base. Also, there was a hole drilled to the centre of the Earth so the hole may have been sealed off. (DW: The Runaway Bride)

2008

Oliver Morgenstern, the final survivor of the Royal Hospital tells the World what has happened on the Moon.

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 they died, along with the rest of the hospital, when their oxygen ran out. The only survivor was Oliver Morgenstern who was passed the last oxygen tank by Martha Jones, who gave up her life to save him. (DW: Turn Left)

In the original timeline, the Doctor investigated the hospital instead of Sarah Jane, Luke, Maria and Clyde under the alias "Mr Smith" and no one suffocated because he found the Plasmavore in time. Shortly after, he took on Martha Jones as a companion. (DW: Smith and Jones)

Because those events hinged on the Doctor meeting Martha Jones, in this timeline, the events created by Harold Saxon also would never have occurred and the Archangel Network or the Valiant were never designed or built, among other changes such as Captain Jack Harkness never reuniting with the Doctor.

Rose Tyler visits Donna and advises her to persuade her family to spend Christmas some place other than London. (DW: Turn Left)

December 25, 2008

Mushroom cloud from Titanic impact

A replica of the Titanic crash-lands onto Buckingham Palace and destroys the Greater London Area and floods the whole of Southern England with radiation. Donna's family, who did decide not to stay in London for the holidays, having won a luxury getaway in a raffle, watch the events on television. (DW: Turn Left)

In the original timeline, this crisis was averted thanks to the Doctor. Although the city was nearly abandoned in the main timeline, this seems not to be the case here. Also, The Doctor stated that if the Titanic crash-landed on Earth, it would wipe out all life. (DW: Voyage of the Damned)

2009

The Adipose wreak havoc in the United States.

England has come under martial law in order to deal with the crisis caused by the nuclear explosion. The United States promises fifty billion pounds in financial help for Great Britain but this plan has to be abandoned when sixty million Americans are 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 Adipose plan targeted Great Britain and 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 southern England.

File:Jacks death.jpg

Rose and Donna see Torchwood Three save the world, at the cost of their lives.

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 of Torchwood Three 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. Rose Tyler once more appears to Donna to try to persuade her to help change back the timeline. (DW: Turn Left)

This is possibly due to the fact that without "Harold Saxon" to design it, 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 indicates they learned of the Sontaran attack.) (DW: The Sontaran Stratagem/The Poison Sky)

Roughly three weeks after the Sontaran Invasion, the British government makes a new law (England for the English) forcing all non British citizens in Britain to go to "labour camps". Soon afterwards, the stars begin going out. (DW: Turn Left)

After the timeline is corrected, the stars' fading is discovered to be an effect of the reality bomb. (DW: Journey's End)

Negation

Alternate Donna dies.

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)

Behind the Scenes

• It is not actually a parallel world since the walls between realities were sealed in Doomsday. This was made explicit by the production team. Rather it is an altered version of the Doctor's world.
