2009

January - March

 * Dr. Owen Harper, who continues to have difficulty accepting his new undead existence, was relieved of his duties with Torchwood Three (though he continued to help out as their new tea boy) as Martha Jones agreed to stay on as medical officer. After a fruitless suicide attempt, Harper began to come to terms with his death and returns to active duty for a mission to retrieve an alien artefact from a dying millionaire, Henry Parker, who reveals intimate knowledge about Torchwood and its personnel before his passes away. With Harper reinstated, Jones departs Torchwood to return to her duties at UNIT. Soon after, Harper successfully talks a young woman out of committing suicide. (TW: A Day in the Death)
 * Gwen Cooper and Rhys Williams are married, despite trouble with Nostrovites. (TW: Something Borrowed)
 * The Torchwood Three team investigates the Night Travellers. (TW: From Out of the Rain)
 * Gwen Cooper investigates the disappearance of Jonah Bevan and others who were lost through the Cardiff Rift and discovers Flat Holm Island. (TW: Adrift)

March

 * Captain John Hart places bombs in an abandoned building where the Torchwood team, except for Gwen, were investigating. All four experience flashbacks after the detonation. (TW: Fragments)
 * After regaining consciousness the Torchwood team try to stop John Hart. Later that night a series of alien attacks occur in Cardiff, including Weevils killing four senior Cardiff police officers, a Hoix let lose in a hospital where it was captured by Owen Harper, a group of men in cloaks haunt a building only to be shot dead by Toshiko Sato and Ianto Jones, and John Hart captures Jack Harkness and sets off several bombs in buildings across Cardiff. It was then revealed Jack's brother Gray was forcing John Hart to do his bidding. Gray unleashes all of the Weevils in the sewers on Cardiff, shoots Toshiko, who later died of her wounds, and Owen was disintegrated by nuclear radiation following the actions of Gray and John Hart, who helps Captain Jack stop Gray. (TW: Exit Wounds)

Spring, Prior to Easter

 * Martha Jones calls in the surviving members of Torchwood Three for their help with an incident at CERN. (BBCR: Lost Souls)
 * By this time, conspiracy theorists have begun noting the disappearance of bees from the planet Earth, which was also noted by Donna Noble. (DW: Partners in Crime, et al) It was later discovered that they have left Earth in anticipation of its imminent relocation to the Medusa Cascade. (DW: The Stolen Earth)
 * Thousands of Adipose are born from people's fat and walk around the streets. During this time, Donna Noble reunites with the Tenth Doctor and begins her travels with him. Before leaving with the Doctor, however, Donna briefly encounters Rose Tyler (although she is unaware of Rose's identity). (DW: Partners in Crime)
 * The Sontarans invade Earth. During this event, Martha Jones was temporarily reunited with the Tenth Doctor and met Donna Noble for the first time. Donna also narrowly missed witnessing a brief transmission from Rose Tyler in the Doctor's TARDIS. As part of the Sontaran invasion plan, all ATMOS-equipped vehicles begin emitting a toxic gas intended to transform the world's atmosphere into a more hospitable one for Sontaran offspring; numerous fatalities were reported worldwide before the Doctor disables the devices. Afterwards, the ATMOS devices were removed from the planet's vehicles. (DW: The Sontaran Stratagem/The Poison Sky)
 * The Earth was relocated to the Medusa Cascade by the Daleks under the control of the Supreme Dalek and Davros. Despite the relocation, the planet retains a full communications network. An invasion of Earth by the Daleks commences and a number of humans were taken to "the Crucible", the Dalek mothership, where they were killed in tests of the reality bomb. The current Prime Minister is shot down by Daleks. As part of a counter-insurgency against the Dalek invasion, former Prime Minister Harriet Jones brings together a number of the Doctor's former companions, including Captain Jack Harkness, Sarah Jane Smith, and Martha Jones in order to contact the Tenth Doctor, and before she herself was killed by the Daleks. Rose Tyler, meanwhile, contacts Donna Noble's family and was ultimately reunited with the Doctor. During this incident, The Doctor undergoes a partial regeneration in order to repair damage from a Dalek blast; as a result of this, the Doctor's severed hand later forms a mental link with Donna and grows into a second version of the Doctor, but one that's half-human without Time Lord biological abilities such as regeneration. During this incident, Martha Jones, under orders from UNIT, reveals the existence of the Osterhagen Key, a weapon capable of destroying Earth. Due to her interaction with the second Doctor, Donna briefly gains the knowledge of a Time Lord, and with her help the two Doctors were able to defeat the Daleks. Afterwards, the Doctor and his companions were successful in restoring Earth to its original location using the TARDIS; this sparks worldwide celebrations around the planet. Afterwards, Mickey Smith chooses to remain on his original Earth instead of returning to Pete's World, Harkness offers Martha Jones a job with Torchwood Three, and the Doctor returns Rose and Jackie Tyler to Pete's World, along with his clone. Donna Noble was returned to her family, but with all memories of the Doctor wiped from her mind due to the danger to her survival posed by her transformation. (DW: The Stolen Earth/Journey's End)
 * At some point during these events, a young girl named Adelaide Brooke loses her family and encounters a Dalek that, for reasons unknown to her, chooses not to exterminate her. This event inspires her to become an astronaut, becoming a trailblazer for human exploration of space - in her case, establishing the first human base on Mars in 2058 and, in turn, inspiring generations of Brookes who further expand human reach into the stars. (DW: The Waters of Mars)
 * In the aftermath of the Medusa Cascade incident, the human race on Earth began coming to terms with the fact it was not alone in the universe. While many accept it, others experience crises of faith and a large number of people commit suicide. Brian Green becomes British Prime Minister sometime before September. (TW: Children of Earth: Day One)

 * The Trickster uses a time fissure to trick Sarah Jane into saving her parents' lives in 1951 and creating an alternate timeline where he has drained the life out of Earth and enslaved humanity. Sarah Jane and her young friends return to 2009 after her parents prevent this alternate timeline by sacrificing themselves in 1951. (SJA: The Temptation of Sarah Jane Smith)

September

 * Over the course of five days, every child on Earth periodically stops in their tracks and begin reciting the same message (permutations of "We are coming"). Officially, Earth's governments claim it to be caused by a form of virus. Behind the scenes, the truth was this was a message from the 456, a race that had visited Earth in 1965 and negotiated the payment of 12 orphan children in exchange for the cure for a pandemic-level influenza virus. The 456 return to Earth and demand the payment of a significant percentage of Earth's children (for use in creating a narcotic). As part of a cover-up to divert blame away from the UK government, which brokered the original deal, the Torchwood 3 hub in Cardiff was destroyed and attempts were made to assassinate Jack Harkness, Gwen Cooper and Ianto Jones. During the course of events, Thames House becomes the centre of 456-related negotiations, and at one point all occupants of the building were exposed to a deadly gas, killing all except for Mr. Dekker and Jack Harkness. Among those killed was Ianto Jones. Ultimately, through the efforts of Harkness - who was involved in the original 1965 deal - and the sacrifice of Harkness' grandson, the 456 were driven from Earth. Gwen Cooper and husband Rhys Williams learn that she was pregnant. The government of Prime Minister Brian Green was toppled soon afterwards (assumption). Stricken with guilt over the death of his grandson, Jack Harkness leaves Cardiff and spends the next few months wandering the Earth.

 * 26 - During this time a diamond harvested on Gallifrey was sent through time and space and crashes to Earth where it was retrieved by the Master, who uses it to open a portal that briefly allows Rassilon and other Time Lords to escape the Last Great Time War before the Tenth Doctor and, ultimately, the Master, foil their plans. Before this occurs, however, Rassilon undoes the "cloning" of the Master, returning the human race to normal, though they were soon faced with the spectacle of a giant planet appearing in the sky on a collision course; but this, too, was soon undone. A malfunction with the world's wi-fi systems was later blamed for causing mass hallucinations, a cover story concocted by Mr Smith. Shortly after, Luke Smith was nearly run over by a car on Bannerman Road, but was rescued by the Tenth Doctor. (DW: The End of Time)

Ultimately, the collected faith of the people of the world restores the Doctor, leading to the Master's defeat. Captain Jack destroys the Paradox machine, reversing time back to 2008. Afterwards, the Master was shot by his wife, Lucy Saxon, and, refusing to regenerate, apparently died. (DW: Last of the Time Lords)
 * Donna's World - After the Titanic fell to Earth on 25th December 2008, annihilating London and rendering most of southern England unliveable with nuclear radiation, Great Britain had become a police state. Londoners lucky enough to have survived were subject to forced relocations; Donna Noble's family was moved to Leeds. Rose Tyler works with the UNIT of this timeline to help Donna Noble restore the proper chain of events which, at one point, involves sending Donna back to 2007. (DW: Turn Left)
