Draft:Susan Twist (Doctor Who)

Susan Twist is the collective name of several characters potrayed by actress Susan Twist through the fourteenth series of Doctor Who.

Twist first appeared in "Wild Blue Yonder" and made a further appearance in "The Church on Ruby Road" before appearing in every episode of the fourteenth series as seemingly disparate characters.

Fictional biography
Twist first appeared in "Wild Blue Yonder" as the maid of Isaac Newton. She then appeared in "The Church on Ruby Road" as a concert goer.

Twist then appears in the fourteenth series' opening episode "Space Babies" as communications officer Gina Scalzi. She reveals to the Fifteenth Doctor and Ruby Sunday that the babies had been left to die.

In "The Legend of Ruby Sunday" Twist made an appearance as Susan Triad, the head and founder of the fictional company S Triad Technology. Twist first appeared in "Wild Blue Yonder" and made a further appearance in "The Church on Ruby Road" before appearing in every episode of the fourteenth series as seemingly disparate characters. These roles were ultimately connected in the episode, with "S Triad" an anagram for "TARDIS" and "S Triad Technology" was abbreviated to "Sue Tech", which is a homophone of "Sutekh". References to "Triad Technology" had been planted in Doctor Who as early as "The Giggle", where the company was mentioned in dialogue, as well as "The Church on Ruby Road", where a fictional advertisement appeared on a bus.

Development
Davies originally had three additional roles planned for Twist that would have featured in the episodes cold open. These included a nanny pushing a stroller in 1946 Pennsylvania, a blue-skinned extraterrestrial working in an alien diner as a waitress who would have served the Doctor and Ruby, and a "human astronaut addressing a colony of giant ants". The scene in Pennsylvania would have also featured inventor Albert Einstein and activist Paul Robeson.
