Barge of the Dead, VOY 6
Voyager gets a Klingon story! Ronald D. Moore’s other Voyager episode (he shares a Story By credit) introduces the flip to StoVoKor, Gre’thor, as well as giving B’Ellana Torres her best storyline.
In this episode you’ll see Tuvok handle a Bat’leth like nobody’s business and you’ll see The Doctor and Seven of Nine harmonize to the Klingon Drinking Song championing Kahless the Unforgettable. Awe-some.
