In the scene when Cmdr. Ivanova is in her quarters talking with Mr. Welles about the Nightwatch program, Mr. Welles refers to the newly formed "Ministry of Peace" or "MiniPax, as we call it around the office". This serves both as foreshadowing what is to come and as a nod at George Orwell's dystopian story 1984 where the main character, Winston Smith, was a worker at the Ministry of Records, or MiniRec.
