Passage: Chibnall suggested including a "bonkers" gang of characters picked from around time and space. He felt that Doctor Who could have "collisions of characters that no other show in the world can do", and that it was about finding a "disparate" group of characters who would "bounce" off each other. Nefertiti's decision not to return to her own time fits in with the historical record, as the date and cause of her death are unknown. Chibnall asked to introduce Rory's father, as Amy and Rory would be leaving in four episodes and Rory's family life had not been explored yet. Mark Williams who played Rory's father previously appeared in the Fifth Doctor audio adventure The Eternal Summer. Rupert Graves, who played an Edwardian hunter in this episode, previously worked with Moffat on the BBC series Sherlock. David Bradley's character, Solomon, was modelled on a "well-known nightclub owner with long hair". Chibnall described him as "half businessman, half Somali pirate". Bradley and Williams had previously worked together on the Harry Potter film franchise. Bradley was later cast as the First Doctor William Hartnell for the 50th anniversary documentary drama An Adventure in Space and Time. Comedy duo Mitchell and Webb provided the voices of Solomon's two robots; executive producer Caroline Skinner called the casting choice "perfect". Richard Hope, who played the Silurian Bleytal, previously appeared as Malohkeh in the episodes "The Hungry Earth", "Cold Blood" and "The Wedding of River Song".

Passage: The Bedrock Community Players is mounting A Christmas Carol, and all of the town's citizens are either planning to attend or be involved in the production: Barney Rubble is playing Bob Cragit, with Betty as Mrs. Cragit and his son Bamm-Bamm as Tiny Tim; Mr. Slate is Jacob Marbley; Wilma Flintstone is serving as the stage manager, while her daughter Pebbles plays Martha Cragit; even Dino has a role, playing the Cragit's family pet. It is Fred, though, who has landed the leading role of Ebonezer Scrooge. Unfortunately, he has let his role go to his head, thinking himself a star and spending all of his time rehearsing his lines rather than focusing on his job or family. On Christmas Eve, in his rush to get to work, Fred forgets that he must take Pebbles to "cave care", and later to pick her up from cave care. When Fred arrives at the theater, he discovers a furious Wilma, who breaks down in tears as she tells Fred about his mistake.
