Goof: Worf said the "the Rio Grande is available" when asking for a runabout. Yet the Closed captioning says that the Mekong is the ship available.
Goof: During the fight with the Klingons, Worf is stabbed in the side of his body, however, in subsequent shots, the wound is on his shoulder.
Nitpick: At the beginning of the episode, Quark is complaining about Kor's exaggerated battle stories, saying that there is no profit to be found in them. However, they seem to be attracting a fair few people to his bar, thus making him a profit.
Nitpick: It is stated at the end of the season three episode "Distant Voices", that Lethean telepathic attacks are almost always fatal, yet Kor manages to survive one with only a slight disorientation.
Kor: The sword will unite us if its held in the hands of a true Klingon, not a politician like Gowron, or some toothless figurehead like the Emperor. The sword must rest in the hands of someone who has been hardened by battle, pure of heart, who understands loyalty and honor. A warrior like Kang and Koloth.
Worf: Someone like you?
Kor: The Empire could do far worse.
Kor: Damn that Ferengi and his replicated bloodwine!
Kor: (reaching for the Sword of Kahless) Just let me hold it one more time.
Worf: (stopping him) The Sword is not meant for us! It was never our destiny to find it.
Kor: (Jadzia shoots Worf, who is in a clinch with Kor) Dax, I knew in the end you'd choose me! We're blood brothers...
Jadzia: (interrupting) Be quiet! (she shoots Kor)
Worf: A true warrior has no need to exaggerate his feats.
Kor: Well, you better hope that I exaggerate, or when they start singing songs about this quest and come to your verse, it will be 'And Worf came along.'
Jadzia: I'd like you to meet our strategic operations officer, Commander Worf.
Kor: Ah, Worf the traitor. The pariah, the lowest of the low... it's a pleasure to meet you. Any enemy of Gowron and the High Council is a friend of mine.
Kor: Did you see the look on the face of that Klingon I killed? It was as if he understood the honor bestowed upon him. The first man in a thousand years to be killed by the Sword of Kahless!
Jadzia: I'm sure he was very proud.
Worf: It would be an honor to accompany you... if you'll have me.
Jadzia: We could use another strong arm...
Kor: And a stout heart. Besides, it will annoy Gowron.
Quark: You know what I like about Klingon stories, Commander? Nothing. Lots of people die and nobody makes a profit.
The word 'Hur'q' is the Klingon word for 'outsider' and is used to describe a species that pillaged the Klingon homeworld more than a thousand years ago.
The character of Toral would later go on to appear in the PC game, Star Trek: Armada (2000). The storyline builds upon the events depicted in this episode, with Toral trying to seek the Sword of Kahless, in order to become the leader of the Klingon Empire.
Kor blames Worf for his political support of the clone of Kahless, who was created by a group of ambitious Klingon clerics who wanted to return the Emperor to the Empire. This takes place in the Next Generation episode "Rightful Heir".
Cirroc Lofton (Jake Sisko) does not appear in this episode.
Worf makes a citation of the battle between Kor and Kirk in Organia, a reference to the Original Series episode "Errand Of Mercy". John Colicos played the original Kor back in 1967 and also reprised this role in the Deep Space Nine episodes "Blood Oath" and "Once More Unto The Breach". Kor was also the first Klingon to be shown on the Star Trek universe.
Toral, who appears halfway in this episode, is the son of Duras who attempted to acsend to the Klingon Chancellory with the support of his aunts, Lursa and B'Etor, and the Romulans in the Next Generation episode "Redemption".
Ali Baba And The Forty Thieves
When the runabout is approaching the wormhole, Kor lifts up his arms and moves his hand's apart, gesturing for the wormhole to open. Ali Baba does the same thing, whilst saying the magic words "open sesame", when he opens the magical cave containing the stolen treasure.
