Alex (Keeley Hawes) says the names on the deciphered list are old tube station names. These are: Aldersgate, which is now the Barbican station on Aldersgate street; Chigwell Lane, which is now Debden station on Chigwell Lane; Dover street, which is now Green Park station; and, as Alex states in the episode, Gillespie Road is now Arsenal station, named after the football stadium; and Eastcheap is Monument Station, named after the monument to the Great Fire of London, known simply as the monument.
Chris (Marshall Lancaster) refuses to get Shaz (Montserrat Lombard) a "Marathon". Marathon was the UK brand name of the US candy bar Snickers created by the Mars company, which consisted of nougat, peanuts, and caramel coated in milk chocolate. In 1990, the UK version was renamed Snickers when Mars decided to align the UK product with the global Snickers name. Not to be confused with Mars's US-only Marathon bar, which was a braided eight-inch strip consisting of chocolate and caramel. Sold in the US from 1973-1981, this was a similar product to Cadbury's Curly Wurly.

Gene (Philip Glenister) says Martin Kennedy "kept a stack of Color Climax close to his left hand", referring to the hardcore porn magazines produced by the Color Climax Corporation in Denmark starting in 1969, although only watered down soft-core versions were generally available through sex shops in the UK at that time.
Gene (Philip Glenister) says "What if Lee Harvey Oswald shot Elvis and they both flew over the moon?" Lee Harvey Oswald was shot dead by Jack Ruby after being arrested for assassinating president John F. Kennedy during a motorcade at Dealey Plaza in Dallas Texas on 22 November 1963. Elvis Presley is the famous US rock 'n' roll star who died in 1978 but who many people claim is still alive. Tales of sightings of Elvis have been manyfold.

At the RWF meeting, Sara Templeton (Lydia Leonard) refers to US president Ronald Reagan stockpiling neutron bombs. The neutron bomb is a fission fusion thermo-nuclear weapon designed to release a large portion of its energy as energetic neutron radiation, rather than explosive energy. It was conceived by Samuel T.Cohen in 1958 and testing of the device began in 1963 at the US underground test facility in Nevada. Development of the bomb was postponed by president Jimmy Carter in 1978 following protests against plans to deploy neutron warheads in Europe. Ronald Reagan restarted production in 1981. Three types of neutron weapon or ERWs (enhanced radiation weapons) were built: the W66 warhead for the anti-sprint missile system deployed in 1975, retired in 1976; the W70 Mod 3 warhead for short range tactical Lance missiles; and W79 Mod 0 developed for artillery shells. These last two were retired by president George W. Bush in 1992 following the end of the cold war.
Chris (Marshall Lancaster) says, "We both like Kim Wilde". Kim Wilde, (the daughter of 60s pop singer Marty Wilde who had a hit with "Teenager in Love"), the blonde-haired English pop singer, became well known when her first single, "Kids in America" (released 26 January 1981) charted at no.2 in the UK charts. She had four more top 20 hits in the 81/82 period. From 1983 her singles failed to dent the top 20.
