When Mike Milligan is shown to his tiny new corporate office back in Kansas City, what else should be standing on his desk but a state-of-the-art electronic IBM Selectric typewriter. They're not just for women any more.
This is the only episode to include cast members from the previous season. This includes the older Lou Solverson (Keith Carradine), older Molly Solverson (Allison Tolman), Gus Grimly (Colin Hanks) and Greta Grimly (Joey King). It should be noted that Martin Freeman only appears as the Narrator in the previous episode and not his first season character, Lester Nygaard.
Lou (Patrick Wilson) speaks about protecting his family as the rock all men must push. This ties into the book that Noreen (Em Haine) is reading, The Myth of Sisyphus by Albert Camus. Sisyphus was a figure in Greek mythology that was forced to push a rock to the top of a hill where it slides down and he must start all over again. Camus stated that people must imagine Sisyphus happy. Lou is happy pushing his rock.
Betsy Solverson (Cristin Milioti) reacts to a Camus quote with "I'm guessing he doesn't have a 6-year-old girl". Albert Camus did in fact have 2 children.
