Continuity

 * Upon learning from the Doctor that they have travelled back in time to 1980, O'Donnell notes that it is pre-Harold Saxon (TV: The Sound of Drums / Last of the Time Lords) as well as "pre-the Moon exploding and a giant bat coming out." (TV: Kill the Moon)
 * When meeting Albar Prentis, the Doctor notes that he has met Tivolians before and that he isn't "a fan." (TV: The God Complex)
 * The current masters of Tivoli who have sent Prentis to Earth to bury the Fisher King are the Arcateenians. (TV: Greeks Bearing Gifts, Invasion of the Bane )
 * The Doctor says "I've had a good innings" when he prepares to meet his potential end. The Sixth Doctor said this right before regenerating in two differing accounts, AUDIO: The Brink of Death and PROSE: Spiral Scratch.
 * The Doctor repeats the phrase "tick-tock" while contemplating his apparent death. During his previous incarnation's life, the Peg Dolls' nursery rhyme also used the phrase for the same purpose (TV: Night Terrors et. al TV: The Wedding of River Song).
 * The Doctor refers to his current regeneration as a "clerical error". It was only made possible by going past the limits of his original regeneration cycle once it was all used up and the Time Lords had given him a new cycle. (TV: The Time of the Doctor)
 * The Doctor states that Earth is under his protection. (TV: The Christmas Invasion, The Eleventh Hour)
