- Bonus Material: George Mann wrote a Story Arc for Doctor Who Legacy, in which the War Doctor goes back in time after the events of the novel and rescues Cinder, knowing that the general Time Crash happening in Legacy would keep the Web of Time from shredding as a result. (Note that this doesn't affect the events of the novel — the events of Legacy will "snap back" to the regular timeline after the Time Crash plot is solved, and no one will remember a thing. Which doesn't stop the War Doctor from trying to save Cinder regardless.) He also wrote a story in the fan-made charity anthology "Seasons of War" featuring a vignette between the War Doctor and Cinder.
- Word of Gay: Mann has confirmed in interviews that Cinder is a lesbian.
