In addition to the Star Wars reference of Dean and Sam claiming to be agents Ford and Hamill, Andrea's son is named Lucas, a reference to Star Wars: Episode IV - A New Hope (1977) creator George Lucas.
At the end of the episode Dean tells Lucas to remember one important thing "Zepplin rules." In December, 2016 Jensen and Daneel Ackles welcomed twins, Zepplin and Arrow.
The Cabin in the opening shot is the same one used in Dead Like Me Season 1 Episode 13 Vacation .
