Worldbuilding

 * According to Payne, the time period is "1890, give or take a few years." He is from 2000 years in the future.
 * 2011 is a stable point in time.
 * Payne uses time bombs, accelerating centuries in seconds.
 * The Time Eaters were like crabs existing in the event horizon of a black star or sun, feeding off fluctuations in the time gradients, converting time to energy. They want to use a time break to leave the black star and feed on all time.
 * Payne lost his love Cenya during a gravity spike. The Time Eaters later assume her form.
 * Sergeant Quick tells Professor Litefoot that the Metropolitan Police Service is issuing the cover story that the metal spheres are a stunt by a group of Bohemian sculptors.
 * According to Quick, the police have interviewed the Irish author and playwright, Oscar Wilde.
 * As a result of the time breaks, Leela and Jago find a 20th century radio playing a BBC shipping broadcast. They later see a British Spitfire and a German Messerschmitt fighting each other in the sky over 1890s London which had come from the Blitz in the early 1940s.
 * Payne has brought a sabre-toothed tiger to London in the 1890s.
 * The version of Jago from several hours in the future, which is eventually rendered an alternative timeline, is killed by one of Payne's traps.
 * Friendship is rare among the Sevateem. They believe spirits walk the world until a sacrifice is made in their name.
 * Morse code is mentioned.

 * Ellie refers to the fact that Litefoot allowed her to stay at his house when she was "ill". (AUDIO: The Theatre of Dreams, The Ruthven Inheritance)
 * It would later be revealed that Leela was unable to return to Gallifrey using her Time Ring as the interference from Payne's temporal experiments had prevented it from functioning.
