(TV: Aliens of London/World War Three) His tenth incarnation, however, would set in motion her deposition after she ordered the destruction of the retreating Sycorax. (TV: The Christmas Invasion) She would help save the world one final time against the Daleks. (TV: The Stolen Earth)
- The TARDIS materialises around Bill's possessions. It had done so previously around passengers. (TV: The Parting of the Ways, Blink, The Runaway Bride, Dinosaurs on a Spaceship, Hell Bent)
- The Doctor remarks on the Time Lords' dress sense, having done so earlier in his life. (TV: Time Crash, Journey to the Centre of the TARDIS, Nightmare in Silver, Hell Bent)
- The Doctor reveals he's a Time Lord. (TV: The War Games et al., Doctor Who, The End of the World et al.)
- The Doctor mentions regeneration, but glosses over it, similar to how his tenth incarnation did such with Martha Jones in regards to his race. (TV: Gridlock)
- The Doctor had previously faced creatures who absorbed people into walls. (TV: Flatline)
- Bill introduces the Doctor as her grandfather. The Doctor once travelled with his granddaughter Susan Foreman, who called him grandfather. (TV: An Unearthly Child - The Dalek Invasion of Earth, The Five Doctors)
- Bill's sexuality is mentioned as she informs a male flatmate, after he makes overtures, that he isn't her type and she prefers girls. (TV: The Pilot)
- Bill puts a picture of her mother, which was taken by the Doctor, on the wall. (TV: The Pilot)
- One of the flat mates theorise dolls could be creeping around upstairs. The Doctor encountered a house of dolls in his eleventh incarnation. (TV: Night Terrors)
- The Vault is tended to by Nardole once more, the Doctor revealing a piano is inside. (TV: The Pilot, Thin Ice)
- In an attempt to convince herself that there's nothing strange about the house, Bill remarks that "There's no living puddles or weird robots, big fish..." (TV: The Pilot, Smile, Thin Ice)
- The Doctor claims sleep is for tortoises, (TV: The Talons of Weng-Chiang) as he doesn't sleep much himself. (TV: Good Night)
