The episode opens with a scene from "fifty years ago" in Maine showing a young Eleanor Wright and her father watching a television show. The robot on the show utters the classic line, "Danger Will Robinson. Danger!" This is from the classic television show "Lost in Space", which ran on television from 1965-68.
Alice Wetterlund (D'Arcy) and Michael Cassidy (Dr Ethan Stone) were both on People of Earth (2016).
In the opening scenes, young Eleanor Wright (Alix West Lefler) is using a Polaroid SX-70, the first instant SLR camera.
