Continuity

 * Before the Doctor departed Gallifrey, he possessed a Type 50 TARDIS but abandoned it. His first TARDIS eventually escaped Gallifrey on its own and made its way to Valderon in the 36th century, where it again encountered the Doctor, who was by then in his fifth incarnation. (AUDIO: Prisoners of Fate)
 * Susan enters another time capsule but the Doctor does not follow. He briefly speaks with someone outside, before pulling Susan out and entering another parked alongside it. (TV: The Name of the Doctor)
 * The Doctor finds a food machine in the TARDIS. (TV: The Daleks, The Edge of Destruction)
 * Susan coins the term "TARDIS" from the principles on which the time capsule works: "Time and Relative Dimension in Space." The Doctor tells her that the term already existed but she did not believe him. (TV: An Unearthly Child)
 * There are sentient chairs on Gallifrey. (PROSE: Lungbarrow)
 * The TARDIS again assumed the form of a boulder on Iwa. (PROSE: Frayed)
 * In his capacity as Lord Burner, Irving Braxiatel was ordered by Lord President Pandad VII to burn "an old man" and "his granddaughter," who are implied to be the Doctor and Susan, from history. He disobeyed this order and the intended victims stole a TARDIS and fled Gallifrey. The very same day, Pandad died when a power relay in his office overloaded. An inquiry headed by Braxiatel found that this was an accident. (AUDIO: Disassembled)
 * The Fourth Doctor later told Adric that there were "pressing reasons" for his departure from Gallifrey. (TV: Logopolis)
