	Philip Kim's original idea for this episode involved Weyoun coming to Sisko to ask for his help because the Founders are breeding a new race called the Modain, who are to replace the Jem'Hadar. The Modain are far tougher and more aggressive than the Jem'Hadar, and even more loyal to the Founders. Weyoun convinces Sisko that it would be in everybody's best interest to destroy the breeding facility where the Modain are being developed. After destroying the facility however, Sisko discovers that Weyoun was lying – the Modain were not being bred to replace the Jem'Hadar, they were being bred to replace the Vorta. Ira Steven Behr had been looking for a good Weyoun/Odo story since the sixth season, and he believed that Kim's idea could be modified to fit. Consequently he assigned the script to David Weddle and Bradley Thompson, who altered Kim's story into the final episode. (Star Trek: Deep Space Nine Companion)
	The origins (or possible origins) of the Vorta are revealed in this episode. Ira Steven Behr came up with this story, and of it, he says, "I like to get the audience thinking one way about a character or a race, making them think that these are definitely the bad guys. Then you slip something like this in so they have to reevaluate the opinion you've already given them. These are still the bad guys, but now, at least, you understand something about why. So I just loved that the Vorta, this calculating, Machiavellian race, started out as Hobbit-like cute little creatures who were genetically altered and directed to do these horrible things." (Star Trek: Deep Space Nine Companion)
	The writers saw Odo's reluctant acceptance that for the Vorta, he truly is a god, as being his first step in deciding to return to the Founders at the end of the series. (Star Trek: Deep Space Nine Companion)
	Of the B-story, which is based on the 1961 Joseph Heller novel Catch 22, with Nog taking the role of Milo Minderbinder, Aron Eisenberg states, "This was Nog taking the same energy and Ferengi ideals he'd had before he joined Starfleet and incorporating them into his goals in Starfleet. What I love about having an honest Ferengi in Starfleet is that he knows how to manipulate the situation. In Starfleet, you go through certain channels to get things done. It's all very official. Nog just feels that you don't have to. You can do it this way and it works just as easily and it's much faster. He thinks it's perfectly natural to do this. No one else in Starfleet would have done things this way except Nog." (Star Trek: Deep Space Nine Companion)
	The idea of an officer who wants to sit behind Sisko's desk was Ira Behr's joke about how obsessed Trekkies can become. (Star Trek: Deep Space Nine Companion)
