The writers saw the B-story of this episode as an important indication of how DS9's Worf was going to be different from TNG's Worf. As Ronald D. Moore explains, "He used to be a cop, more or less, on the USS Enterprise-D, but it's not going to be like that anymore. We wanted to keep emphasizing, 'this is not TNG. The station doesn't work like the Enterprise. Worf is going to have some troubles fitting in, but he's going to learn.'"

When Goran'Agar explains to Bashir about his freedom of Ketracel White, it happened 3 years previously. Later when discussing it, they both say it happened 4 years ago.
