Inside the library, The Doctor has kept The History of the Time War, a book outlining the history of the Time War. (Rose, The Unquiet Dead)
Clara comes across The Doctor’s cot. (A Good Man Goes To War, The Gunpowder Plot) As the TARDIS leaks the past many voices can be heard. a) The voices are, in respective order:
The voice of Susan says, “I made up the name ‘TARDIS‘ from the initials: Time and Relative Dimension In Space.” (An Unearthly Child), The Third Doctor saying, “The TARDIS is dimensionally transcendental” and Jo, asking”What does that mean?”, the Eleventh Doctor saying, “You sexy thing!” then Idris (the TARDIS in human form) replying, “See, you do call me that! Is it my name?” followed by The Doctor’s exclamation of “You bet it’s your name!” (The Doctor’s Wife), The Fourth Doctor saying, “That’s trans-dimensional engineering. A key Time Lord discovery.” (The Robots of Death), the Tenth Doctor saying, “The assembled hordes of Genghis Khan couldn’t get through that door, and believe me they’ve tried.” (Rose)
Martha saying, “It’s just a box with that room crammed in!”. (Smith and Jones)
