Terry Farrell on Dax in "Invasive Procedures":
"I approached [the scenes in the
Infirmary] with the idea that Jadzia is scared, that she feels helpless.
She cares very deeply for everyone on the station and is afraid for
them. That's why she's willing to say, 'Fine, I'll give my life for
everybody and you can have Dax.' But that had been while the strength of
Dax was inside of her, telling her that everything was going to be okay.
Once the worm is gone, she's only twenty-eight years old, and it's like,
'Wait, I haven't lived that munch life yet.'" |

The episode marked the first use of Bashir's surgery, a
new redress of a swing set that is attached to the Infirmary. The swing
set also found use as the station's schoolroom and security. |
