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.
- 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).
- Hey, It's That Guy!: Three years later, the actress playing Melora would swap a starship for another kind of spaceship.
- What Could Have Been: It was the original intention to have a wheelchair-bound alien as the science officer on the station, but it was decided that it would be too complicated for filming purposes, so they went with a Trill instead. They kept the idea in mind, though.
