Passage: Hamilton followed his mother as a Christian Scientist, and attended Claremont Fan Court School and then Eton College. He did National Service in the Coldstream Guards from 1955 to 1958. His father had been wounded while serving with the same regiment in the Second World War. Hamilton then worked in the City of London as a gilts broker. He was a member of the London Stock Exchange from 1967 to 1980. He remained in the City for only a short period, leaving when he inherited two estates from his father's cousin. He married his wife, Corinna Dixon, in 1967, and they had four sons together. He succeeded his father as Baron Hamilton of Dalzell in 1990, inheriting land near and properties in the village of Betchworth in Surrey, and a Regency mansion.

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 United States Navy dog handler hazing scandal was a pattern of misconduct engaged in by members of the United States Navy at Naval Support Activity Bahrain between 2004 and 2006. Naval investigators documented nearly 100 incidents of abuse committed against several members of a Military Working Dog (MWD) unit stationed at the United States military base at Juffair. Documented incidents of abuse include racial intimidation, sexual harassment, physical abuse and anti-gay harassment. One sailor, Master-At-Arms 3rd Class Joseph Rocha, suffered post-traumatic stress disorder because of his abuse at the hands of fellow sailors, and he alleges that another sailor committed suicide because of her treatment. The Navy investigated the allegations in 2007 and documented the abuse, but took little substantive action. However, Pennsylvania Congressman Joe Sestak, a former Vice Admiral, demanded a new examination of the report's findings which led to the disciplining of Rocha's former superior, Chief Petty Officer Michael Toussaint (later Senior Chief Petty Officer). The scandal came to widespread public attention as United States President Barack Obama faced increased pressure to repeal the military's gay-exclusionary policy known as "don't ask, don't tell" (DADT).
