April

 * The Sontarans invade Earth. During this event, Martha Jones is temporarily reunited with the Doctor and meets Donna Noble for the first time. Donna also narrowly misses witnessing a brief transmission from Rose Tyler in the 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 are reported worldwide before the Doctor disables the devices.

An invasion of Earth by the Daleks commences and a number of humans are taken to "the Crucible", the Dalek mothership, where they are killed in tests of the reality bomb. 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 Doctor, and before she herself is killed by the Daleks. Rose Tyler, meanwhile, contacts Donna Noble's family and is 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.

Afterwards, the Doctor and his companions are 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 is 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) (Takes place within 6 weeks of NSA: Beautiful Chaos)
 * 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)

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 is this is 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 is destroyed and attempts are 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 are exposed to a deadly gas, killing all except for Mr. Dekker and Jack Harkness. Among those killed is Ianto Jones. Ultimately, through the efforts of Harkness - who was involved in the original 1965 deal - and the sacrifice of Harkness' grandson, the 456 are driven from Earth. (TW: Children of Earth Date based upon on-screen evidence, specifically a newspaper headline.)
 * During the course of these events, Gwen Cooper and husband Rhys Williams learn that she is pregnant.
