The Inforarium (home video)

The Inforarium was a Doctor Who mini-episode made exclusively for the series 7 DVD and Blu-ray box sets. It featured a pre-Snowmen Eleventh Doctor, and actually demonstrated how he was deleting himself from history to support his faked death, as was mentioned multiple times throughout the 2012 series.

Plot
The Inforarium — the greatest source of illicit information in recorded history — is compromised. The Doctor appears in a hologram — "Who the hell are you?". He tells a guard that he will be erasing all traces of himself from their database, making everyone forget what they've heard through means he'd adapted from the Silence. At the end of the message, the guard completely forgets the whole ordeal. Then it replays... "Who the hell are you?"

Cast

Species

 * The Inforarium sells information to the Daleks, the Cybermen and the Sontarans.

Continuity

 * The Doctor is erasing himself from history. (TV: The Doctor, the Widow and the Wardrobe, Asylum of the Daleks, The Angels Take Manhattan)
 * He adapted the Silence's natural defence mechanism for his own means, and uses it to make any information on him learned at the Inforarium forgotten in seconds.
 * He mentions being the last of the Time Lords. (TV: The End of the World, The Long Game, Doomsday, Gridlock, Utopia, Last of the Time Lords, The End of Time, The Beast Below, Amy's Choice)
 * The Doctor's wearing his tweed jacket outfit, and thus takes place during his travels with Amy and Rory, or at least in between them. His costume changes thereafter, by The Snowmen.
