After CBS and Paramount Pictures sued the producers of the "Star Trek" fan film Prelude to Axanar (2014) for copyright infringement, the overt "Star Trek" references were removed from this episode before it entered production. Many of the character names were changed. For instance, Admiral Pavel Chekov became the Admiral (though his first name is still Pavel), Tuvok became Kovok, Jadzia Dax became Jada, Chakotay became Cordero, Nog became Fnaxnor and Molly O'Brien became Ensign O'Riley. Similarly, the Federation became the Confederation. However, at one point, the Admiral refers to Jacob as "Mr. Sisko," suggesting that he is still intended to be Jake Sisko.
