Quark calls in the help of Odo to remove an old drunk Klingon keeping a holosuite occupied. His name is Kor and he is visited by Koloth, another old Klingon, who leaves him again when he finds out Kor is drunk. When Dax hears about it, she immediately recognizes their names. They were friends of Curzon Dax and when the two are joined by yet another Klingon, Kang, Jadzia knows why they're on the station. In the past Curzon made a blood oath with the three to kill the Albino, a bandit who was defeated by them. He swore revenge and killed their three first born sons, including Dax' godson. For a lifetime they tried to find him and Kang now finally located him. Koloth and Kang however are disappointed to discover Curzon is dead. They don't want to take Jadzia along, while she feels she must fulfill the oath. She tries to convince Koloth and Kang to change their decision. Written by Arnoud Tiele (imdb@tiele.nl)

[first lines]
Quark: He only paid for one hour. He's been in there for three, fighting the Battle of Klachdachbrach or some such thing over and over.
Odo: The Battle of Klach D'Kel Brakt is a legendary Klingon victory over the Romulans almost a century ago.
Quark: Well, he's been losing it all afternoon. And he says he's not coming out until he wins! I banged on the door; he sealed himself in. I threatened to shut off the power; he threatened to kill me.
Odo: [with mock sympathy] Ooh!

User Reviews

An excellent episode, as well as an affectionate love letter to the backstory of the classic Star Trek mythology!
8 March 2021 | by jdlewisincSee all my reviews

Over the course of seven seasons, ST: DS9 gave Star Trek fans some memorable & heartfelt love letters to ST: TOS. One of the very best Star Trek love letters of all time aired on H&I tonight: "Blood Oath". This episode was so much more than a clever & witty ST salute, ala "Trials and Tribble-ations", this episode further fleshed out the already-rich & nuanced backstory of the classic Klingon culture, as well as fleshing out the backstory of Jadzia Dax! On a geeky behind-the-scenes note, this episode was written by veteran television screenwriter Peter Alan Fields, who wrote numerous episodes of ST: DS9, ST: TNG, (including the classic TNG episode: "The Inner Light".) The Six Million Dollar Man, McCloud, and, perhaps the greatest episode of The Man from U. N. C. L. E. Of all time: "The Concrete Overcoat Affair, Parts I & II". ("It's a pineapple!") Twenty-seven years later, the episode still holds up quite well. It's not just a great television episode, its great Star Trek also ! All in all, this was a most wonderful trip down memory lane tonight!
