This particular conversation has been done to death but it is interesting that this is the logical progression of Our Man Bashir, the Ian Fleming Estate almost sued them over Our Man Bashir as the Arthur Conan Doyle estate almost sued tng over Moriarty. So they went with a real spy story, of course Kurtzmann is a massive hack faggot so he over used it but it does work very will within ds9. Just imagine if the writers of this ep had known what they would unleash when they did this.
