Jem 'Hadar #1 (as Michael H. Bailous)


Bashir and O'Brien have concluded a bio-survey in the Gamma Quadrant. They pick up a subspace magneton pulse. While investigating, the shuttle crash lands and they are taken prisoner by a renegade group of Jem'Hadar. Its leader, Goran'Agar, got free of his addiction to ketracel white on this planet, the drug that makes them dependent on the Founders. He's brought a group of Jem'Hadar to be cured too, but the planet's 'magic' doesn't work on them. He asks Bashir to help before their supply of white runs out. While the doctor wants to help them, O'Brien is adamantly opposed. Meanwhile, back on the Deep Space Nine station, Worf spots a known criminal in Quark's bar. He thinks the Ferengi is plotting something and is getting increasingly agitated by the way Odo handles security on the station. Worf decides to take matters into his own hands.

The writers saw the B-story of this episode as an important indication of how DS9's Worf was going to be different from TNG's Worf. As Ronald D. Moore explains, "He used to be a cop, more or less, on the USS Enterprise-D, but it's not going to be like that anymore. We wanted to keep emphasizing, 'this is not TNG. The station doesn't work like the Enterprise. Worf is going to have some troubles fitting in, but he's going to learn.'" See more »


Captain Sisko: Starfleet officers often have trouble learning the unofficial rules of the station. There's no manual to study. You have to learn things as you go. A little different than... life on a starship.
Lt. Commander Worf: When I served aboard the Enterprise, I always knew who were my allies, and who were my enemies.
Captain Sisko: Let's just say, DS9 has more shades of gray. And Quark definitely is a shade of... gray. He has his own set of rules, and he follows them diligently. Once you understand them, you understand Quark. I'd say ...

An interesting dilemma
28 December 2014 | by (Bradenton, Florida) – See all my reviews

"Hippocratic Oath" is an interesting episode of "Star Trek: Deep Space 9". It also marks an apparent attempt to soften Major Kira, as Nana Visitor underwent some sort of makeover that seemed to feminize and soften her character a bit.

When the episode begins, Dr. Bashir and Miles O'Brien are on a mission using the runabout. Interestingly, Miles tells the Doctor that he sometimes wishes Keiko was a man...when the ship is suddenly diverted by what might be a ship in peril. Unfortunately for their bromance, the pair are suddenly taken prisoner by Jem'Hadar soldiers--and many of them seem very content with just executing them. However, their commander isn't so hasty--he NEEDS the Doctor's help. It seems that these super-soldiers CAN exist without the drug given to them by the Founders--or, at least, HE can survive without it. What makes this possible is what he wants to know and he's willing to possibly let the Doctor live if he can unlock this secret. Surprisingly, the Jem'Hadar actually DON'T want to serve the Founders--but without the drug they seem to be unable to say no.

This episode brings up a HUGE problem. As a doctor, Bashir cannot just ignore the Jem'Hadar's predicament. But, as a member of Starfleet, he really should NOT be helping. As for O'Brien--he has complete clarity and this clarity brings these super-friends into conflict with each other.

In addition to this plot, there is a lesser plot involving Worf--who behaves like a total idiot. While he is NOT in charge of security, he seems to think that Odo doesn't know how to do his job!

Overall, a pretty good episode with an interesting predicament. Worth seeing.
