Dorothea "Dodo" Chaplet is a fictional character played by Jackie Lane in the long-running British science fiction television series Doctor Who. An Earth teenager from the year 1966, she was a companion of the First Doctor and a regular in the programme in its third season, from February to July 1966. Only three of the serials in which Dodo appeared as a regular are complete in the BBC archive (The Ark, The Gunfighters and The War Machines). Dodo's personality was an unsophisticated, bright and happy one.
Lane's contract was not extended beyond episode two of The War Machines. To replace her, two new characters, Polly (Anneke Wills) and Ben (Michael Craze), the new faces of Doctor Who in the "swinging" mid-1960s, became companions. Dodo appeared in six stories (19 episodes, of which 11 currently exist in the BBC Archives).
Dodo has appeared in several spin-off productions, including Big Finish audio dramas and novels, all without the involvement of Lane.
Appearances
Television
Dodo is introduced at the end of the serial The Massacre of St Bartholomew's Eve. In that story, the Doctor and Steven travel to 1572 Paris, where they witness the persecution of the city's Huguenot population. Despite befriending a young woman named Anne Chaplet, the Doctor knows he cannot prevent the coming massacre of 10,000 Huguenots, including Anne, by the Catholic French authorities. He therefore leaves in the TARDIS, taking Steven with him. When Steven finds out, he is furious and considers leaving the Doctor while the TARDIS is in 1960s London.
Steven returns at the same time that a young woman wanders into the TARDIS thinking it was a real police box. The Doctor and Steven are taken aback when she introduces herself as Dodo Chaplet and reveals that her grandfather was French. The Doctor speculates that Dodo might be Anne's descendant.
At the end of The Massacre of St Bartholomew's Eve she reveals she has no parents, explaining that she lives with her great-aunt "and she won't care if she never sees me again". She witnesses images of herself on the Celestial Toymaker's memory window from the day her mother died.
In her travels with the Doctor, Dodo travels to the far future, unfortunately bringing the common cold with her to infect humanity's descendants; faces the mad games of the Celestial Toymaker; witnesses the gunfight at the O.K. Corral; says goodbye to Steven in The Savages; and is hypnotised by the rogue artificial intelligence WOTAN in The War Machines.
Halfway through that last adventure, she abruptly departs for a rest in the country after being hypnotised, and never reappears. At the story's conclusion, Polly (who, with Ben Jackson, took Dodo's place as a companion) explains to the departing Doctor that Dodo has decided to remain in the 20th century.
Webcast
In the 2020 webcast Farewell, Sarah Jane, written by Russell T Davies, Dodo is mentioned as being present at the funeral of Sarah Jane Smith. For Dodo to survive into the 21st century would contradict the varying accounts of her death (see below).
Other media
Dodo's life prior to joining the Doctor and the circumstances under which she joined him in the TARDIS were elaborated on in the Past Doctor Adventures novel Salvation, in which the TARDIS, departing after she has entered it, travels to New York City in Dodo's present, resulting in Dodo working with the Doctor and Steven to investigate mysterious beings who appear to be gods. In the Virgin Missing Adventures novel The Man in the Velvet Mask, Dodo has sex and is infected with an alien virus which slowly corrupts her.
