“Deathwalker” is episode nine of season one of Babylon 5.
Ambassador Kosh approaches Talia Winters, as he wants to hire her for business. Important business. Kosh says that everything has been arranged, including payment, and that he will meet her at the Hour of Scampering.
A Minbari flyer is approaching dock and Na’Toth is waiting for someone to arrive when she sees a female who was on the flyer. Na’Toth calls the woman Deathwalker and attacks, doing quite a bit of damage before security manages to pull her off.
Garibaldi says that the woman is a free trader, operating from Minbari space on a Minbari ship but definitely not a Minbari. When Garibaldi mentions the name by which Na’Toth called her to Sinclair, he recognises the name as did Garibaldi.
Na’Toth says that she has blood oath against Deathwalker, Jha’Dur. The latter used Na’Toth’s family in experiments, fatal ones at that. Sinclair says that the invasion of the Narn Alliance sector was 30 years old, and that Jha’Dur should be an old woman by now.
In med bay, the woman is recovering but Dr. Franklin has been unable to identify her species. Sinclair tells Franklin that she is a Dilgar – a race which is supposed to be dead, the last of them being killed when their sun went nova. Jha’Dur was a notorious Dilgar war criminal, with the rank of Warmaster, who performed atrocious experiments and was responsible for slaughter on a massive scale.
G’Kar tells Na’Toth that the Narn she was going to meet was arriving to negotiate with Jha’Dur for something she had. Na’Toth still wants Deathwalker dead, and G’Kar approves of this, but Jha’Dur has something they want. Commander Sinclair gets a message from Earth Central; it seems that they want what Jha’Dur has as well, and Sinclair is supposed to provide passage. Jha’Dur tells Sinclair that she was sheltered by the Windswords, one of the Minbari martial orders, and that the order too says that Sinclair has a hole in his mind.
Deathwalker says that she has developed a universal anit-agathic, a serum that will prevent aging and confer immunity from disease. Immortality in a bottle, and she is living proof of its effectiveness. Dr. Franklin agrees that the serum she has seems to potentially have this ability, and that she is Deathwalker. Jha’Dur says she wants to give it to all the races of the galaxy. However, her mere presence is causing tensions to rise and see seems an unlikely type for an act of such generosity. That’s because there is a very big catch.
Talia’s business between Ambassador Kosh and someone called Abbut seems incomprehensible. Garibaldi and Sinclair shed some light on what Kosh might be after at the end of the episode.
