Sons of Mogh

"Sons of Mogh" is the 15th episode of the fourth season of Star Trek: Deep Space Nine, the 87th episode overall. Set in the 24th century, the series follows the adventures on the Starfleet-run space station Deep Space Nine near the planet Bajor. This episode focuses on the Klingons, an alien race known for their warrior culture. Worf, the only Klingon officer in Starfleet, receives a visit from his brother Kurn, seeking help to escape the dishonor that has befallen their family. This is the last of four appearances of Kurn, each played by actor Tony Todd, in the Star Trek franchise; he was first introduced on the series Star Trek: The Next Generation in the episode "Sins of the Father" (broadcast March 19, 1990). Plot Worf gets an unexpected visit from his younger brother Kurn. Kurn confronts Worf about the dishonor Worf has brought upon their family, the House of Mogh, by rejecting the Klingon Empire's war with the Cardassian Empire. As a result of Worf's choices, his family has been stripped of its wealth, honor, and political power. Kurn has lost everything, and wants Worf to give him back his honor the only way he can, by having Worf ritually kill him. Worf begins the ceremony, but Worf's crewmate Jadzia Dax figures out what he is planning. She and security chief Odo rush to interrupt the ceremony but only after Kurn is stabbed. Dr. Bashir manages to save him. Captain Sisko is furious and forbids Worf from completing the ceremony.
