YMMV / Star Trek Deep Space Nine S 06 E 16 Change Of Heart

• Accidental Aesop: Worf squanders the whole mission to save his wife, directly proving that Starfleet allowing fraternization among its ranks is a terrible idea — or at least that sending lovers/spouses on missions without anyone else is a terrible idea (the latter point being acknowledged In-Universe).
• 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.
• Heartwarming in Hindsight: The episode ends with Worf having to face the possibility that because of his actions, he may never have a command position of his own. Star Trek: Picard would reveal that Worf eventually succeeded Picard as Captain of the USS Enterprise-E after Picard was promoted to Admiral.
• Memetic Mutation: Worf's line, "That is a joke! I get it. It is not funny, but I get it." is regularly used as a response to jokes the meme-user feels have fallen flat (much the same way as "I get it. It ain't makin' me laugh, but I get it").
