Worf's brother Kurn arrives on the station, with a very difficult request. With his lands and rank stripped by Gowron, the younger son of Mogh wants Worf to administer the Mauk-to'Vor. In other words, he wants his brother to kill him to restore his honor.
- Blue and Orange Morality: Kurn admits that he's never been able to understand Worf, though he finally confesses that in his own way Worf is an honorable man.
- Chekov's Gun: Those cloaked mines prove mighty useful later against the Dominion.
- Driven to Suicide: Kurn. First he asks Worf to perform a ritual killing, then he becomes a Death Seeker, and finally decides that he will just blow his brains out with a disruptor. Even though such a death would be dishonorable, Kurn feels being sent to Gre'thor would be preferable to living because he would at least be among Klingons.
- Honor Before Reason: Kurn's a Klingon, what did you expect?
- No Good Deed Goes Unpunished: Worf's stand against Gowron means that his brother loses everything, eventually even his identity.
- Not Quite the Right Thing: Worf's solution for his brother becomes awkward given the elder Son of Mogh eventually regains his honor.
- O.O.C. Is Serious Business: Odo notes that Kurn is fitting in well as a Bajoran security officer, doing everything he's told without complaint. Then he just stands there smiling when a criminal shoots him even though Kurn could have easily disarmed him. Odo tells Worf he won't have Kurn on his team, as a suicidal officer is a danger to everyone.
- Slap-Slap-Kiss: The maiden voyage of the ship Wax (Worfax? Dorf?)
- That Man Is Dead: Kurn gets a new life, complete with new memories and a new identity, courtesy of Worf.
- What Happened to the Mouse?: Kurn's ultimate fate is never revealed, even when Worf joins the house of Martok and becomes one of the most powerful men in the Empire.
- The Star Trek: Klingon Empire novels have Kurn/Rodek serving on the IKS Gorkon and slowly regain his memories.
- What the Hell, Hero?: Sisko tears into Worf, asking why Sisko shouldn't put him on the first transport off the station and that while he has given Worf plenty of leeway with regard to Klingon beliefs, any future attempt to perform a ritual killing on his station will be severely punished.
