Continuity
This story is a sequel to Hornets' Nest and Demon Quest, with the Fourth Doctor, Yates and Mrs Wibbsey reuniting. Serpent Crest begins by picking up from the cliffhanger at the end of Demon Quest. The Fourth Doctor mentions that the Time Lords removed certain events from his memory, just before they force regenerated him at the end of The War Games. In particular, they hid memories of adventures he had with his other incarnations. The Second Doctor encountered his previous and following selves in The Three Doctors. He met them again in The Five Doctors, along with the Fifth Doctor. He also met the Sixth Doctor in The Two Doctors. The Fourth Doctor investigates his past by checking his 500 Year Diary, which was seen with the Second Doctor in The Power of the Daleks and The Tomb of the Cybermen. The visiting Doctor recalls his adventures with the Cybermen in The Invasion and The Tomb of the Cybermen, the Yeti in The Web of Fear and the giant crabs in The Macra Terror. He also mentions an encounter with the Daleks in the diamond mines of Marlion, as mentioned in the Paul Magrs novel Verdigris. The Doctor met the real Rasputin in the novel The Wages of Sin and the audio drama The Wanderer. Notes
Tsar Wars is the only story in all of the Nest Cottage series to contain no narration. Tsar Wars reunites the cast of the 1971 film Nicholas and Alexandra, in which Michael Jayston had starred as Tsar Nicholas II of Russia and Tom Baker co-starred as the mad monk Grigori Rasputin (a role which was influential in Barry Letts' decision, in 1974, to cast him as the Fourth Doctor). Michael Jayston previously appeared in Doctor Who in 1986, playing the Valeyard in the 13-part television serial The Trial of a Time Lord. Paul Chequer played Eugene Jones in the 2006 Torchwood episode "Random Shoes". Terrence Hardiman played Hawthorne in the 2010 Doctor Who television episode "The Beast Below". David Troughton is the son of Second Doctor Patrick Troughton. He previously appeared in Doctor Who in the television serials Enemy of the World in 1967, The War Games in 1969, The Curse of Peladon in 1972, and "Midnight" in 2008. Nerys Hughes previously appeared in the 1982 Doctor Who television serial Kinda, and in the 2008 Torchwood episode "Something Borrowed". References
