- As noted in the concluding episode of this two-parter, the phrase, "Nothing Important Happened Today," comes from King George III's fictional diary entry on July 4th 1776, the same day that America declared Independence.
- This episode marks the first appearance of Assistant Director Brad Follmer, who was named after Chris Carter's writing assistant.
- At one point in the episode, the Lone Gunmen arrive at Doggett's house and Langly's face has been painted blue. This is both a visual reference to the events of the finale of their series, an episode titled "All About Yves", and evidence that the Lone Gunmen managed to escape the clutches of Morris Fletcher after the events of that episode.
