- Accidental Aesop: Worf squanders the whole mission to save his wife, directly proving that Starfleet allowing fraternization among its ranks is a terrible idea.
- Designated Villain: While Starfleet comes down hard on Worf, there's no mention made of any consequences for the person who actually made the decision to send them on the mission together. If it was Kira — and to be fair, it's not clear if she made the decision herself, or someone else did, and she was just relaying the orders — then she's arguably the one who's truly to blame for how the mission turned out, since even if you account for The Main Characters Do Everything, sending any permutation of Dax, Worf, Bashir, and O'Brien other than the one she actually did send would likely have avoided the fiasco that ended up unfolding. Though it would admittedly explain why Worf becomes The Scapegoat, given that Starfleet has no direct authority over Kira, and the Bajoran government has a track record of going easy on resistance heroes.
- They Wasted a Perfectly Good Plot: Since it was known by the time this episode was made that Terry Farrell was quitting the show anyway, this episode could have been her farewell episode (and Farrell suggested that at the time). It would have been more poignant to have Worf complete the mission, only to find out that the mole was lying about having vital intel to save his own skin and then kill him, especially after many fans found Jadzia's demise in "Tears of the Prophets" to be extremely disappointing. In both cases, this was apparently due to the producers believing that Farrell would change her mind and stay on for Season 7.
