The clerk's hairdo (like Rachel's) is 'Bumper Bangs' in front and a 'Victory Roll' in back. This combo was very popular in the 1940s.
When talking to the clerk, Nyx uses a "fake" British accent. The actress, Melanie Liburd, is British, so that's actually her real accent.
The clerk at the store who decrypts a document for Nyx and Two wears her hair in a style very similar to Bladerunner's Rachel (Sean Young).
The title "We Were Family" is likely to be a reference to the 1979 song by Sister Sledge "We Are Family".
