Journey's End

Lore & Background

The episode culminates four series of production, referencing events from 'The Christmas Invasion' where the Doctor's hand was amputated. The plot revolves around Davros and the Daleks utilizing stolen planets within a 'Reality Bomb' to destroy all matter in every universe. A pivotal moment occurs when Donna Noble touches the Doctor's severed hand inside the TARDIS while it is captured by the Daleks; this triggers a new, cloned Doctor to form, saving the vessel from destruction. This Meta-Crisis creates a biological Time Lord-human hybrid who possesses Time Lord knowledge. The episode also features significant lore regarding regeneration: the Doctor halts his own transformation by transferring energy into his severed hand, allowing his body to heal without changing his physical appearance.

In Their Own Story

The TARDIS is transported to the Dalek flagship, the Crucible, where Sarah Jane Smith, Mickey Smith, and Jackie Tyler surrender themselves to board. After Donna touches the hand and creates the clone Doctor, Davros explains the Reality Bomb plan. Martha Jones threatens to destroy Earth while the others threaten to blow up the Crucible. The group confronts Davros alongside the two Doctors and Donna, who attempt to refocus the bomb onto the Daleks using a device. Davros blasts them with electricity, imbuing Donna with Time Lord knowledge that allows her to disable the bomb and the Dalek fleet. Motivated by Dalek Caan's prophecy of extinction, the new Doctor destroys the Daleks and the Crucible. The companions then use the Cardiff Rift as a 'tow rope' to return Earth to its original orbit. In the aftermath, Donna's mind begins to deteriorate from the overload; the Doctor is forced to wipe her memory against her wishes to save her life, leaving him dejected and alone.

Reader's Guide

To watch this episode in its intended form, viewers should seek the unedited version, as international broadcasts like the Canadian CBC cut 21 minutes to fit a 60-minute slot, removing final farewells and the scene of the Doctor alone. The production utilized Castell Coch for the German castle and Southerndown beach for Norway's 'Bad Wolf Bay'. A unique filming technique involved using physical double Colum Regan alongside David Tennant to portray both Doctors in wide shots, while camera locking allowed Tennant to play both roles in closer takes. An original ending featuring Cybermen rising behind the Doctor was cut by Russell T Davies after Benjamin Cook advised against a cliffhanger following such a sad conclusion. Additionally, a scene where the Doctor gives Rose's clone a piece of TARDIS coral was removed for making the farewell 'too long and complicated'.
