Universe (The Folly of Men)
Jenny Cornelius was native to the 1960s London of a universe where versions of Mr Fell's bookshop, Captain Stewart's Intelligence Taskforce and a giant atomic sea monster also existed. The local version of Laura Drake worked for the Taskforce's P.R. office. (PROSE: The Folly of Men) It seemed to be out of synch historically with the home universe of the “Kim's friend” Jenny, who, when shifting from Christmas in her 21st century world to Cornelius's, found herself in Cornelius's native 1960s on Epiphany. (PROSE: Watch the Skies)
Jenny described it as, "the universe of billions of ordinary humans who like thinking they live in a world of physical laws, of rational order, of cause and effect. The kind of place where the word ‘real’ means something. [Inhabitants] live their whole lives never seeing bits of the universe come apart like an old cardboard box held together with off-brand sellotape." (PROSE: Birds and Snakes)
Behind the scenes
This universe contains analogues of various elements of pop culture from the second half of the 20th century, including Doctor Who, Good Omens and the Godzilla franchise. However, as Scott Sanford commented on the Jenny Everywhere Discord server, “given that Mr Fell is in business at the same time that Mr Stewart is employed by the government, it seems to me that Jenny Cornelius lives in a universe near ones we've seen elsewhere but perhaps not exactly those. For example, the shop on Greek Street is not on a corner but is mid-block, unlike what some TV shows might show us”.
