• This episode was dedicated to Rene Auberjonois, James Doohan, and Leonard Nimoy, who inspire us to go boldly.
  
• Like the Discovery season 4 premiere "Kobayashi Maru", the title refers to the Kobayashi Maru scenario, a Starfleet cadet test first shown in the opening of Star Trek II: The Wrath of Khan.
  
• The Proto-Drive took the starship 4000 light years, landing them in the Gamma Quadrant.
  
• The Kobayashi Maru test takes place on the Galaxy-class starship U.S.S. Enterprise NCC-1701-D. The simulation features crew from various Trek series along with their voices. The voices of Rene Auberjonois (Odo), James Doohan (Scotty), Leonard Nimoy (Spock), and Nichelle Nichols (Uhura) were taken from previous episodes/movies. (It's quite apparent, especially with Spock, that the lines are hodge-podged from multiple sources.)
  
• Robert Beltran (Chakotay) and Gates McFadden (Crusher) recorded new dialogue for the episode.
  
• Gwyn is able to decrypt the classified data, and it is revealed that Chakotay was the original commanding officer of the Protostar.
