Trivia

 * As Cecile does not know Deanna Troi, it is presumed that she never watched the original Star Trek series.
 * As stated by Thomas Snow, he has not drank any Jitters coffee since his isolation in the Tannhauser Offsite. He went into isolation 20 years ago, which makes CC Jitters being created before the late 1990s.
 * Cisco uses the phrase Snow Country for Old Men to summarize the events of the episode. This is a clear reference to the film, No Country for Old Men.
