A new officer, Melora Pazlar, arrives at the station. She is Elaysian, from a planet with extremely low gravity, forcing her to use a wheelchair on other worlds. As she and Dr. Bashir become close, he conceives of a "cure" for her.
- Alien Lunch: This is the first appearance of the Klingon restaurant on Deep Space 9.
- Artistic License Biology: It makes little sense that Elaysians, a species which has evolved on a planet with low gravity, would look exactly like humans (except for the rubber forehead).
- Additionally, Bashir states that it's Melora's motor cortex that prevents her from functioning normally under higher gravity, and stimulating it is all it takes to enable her to walk unassisted. This is ignoring the fact that it's her actual musculature, connective tissue, and skeleton that would be unable to tolerate the increased gravity.
- Chekhov's Skill: A variant—Melora's low-gravity background puts her at an advantage over her would-be kidnapper when she disables the artificial gravity on the runabout.
- Due to the Dead: Odo says that, if Quark is killed, he'll buy one of his vacuum desiccated remains.
- No Such Thing as Alien Pop Culture: Averted. Melora and Dax listen to some Vulcan tunes while on the runabout.
- Revenge: Quark is wanted by a man who spent eight years in a Romulan labor camp for smuggling Romulan Ale. Quark turned on him to stay out of prison.
