Lieutenant Jadzia Dax:
You don't know me as well as you think you do. I'm sure you looked at all the training profiles. But that doesn't tell you who Jadzia really was before she was joined. She was the quietest, shyest, most withdrawn young woman you've ever known - brilliant, top grades... and not a clue to what life was about. She'd never lived outside the program. And it didn't matter because she was sailing through it. Until she met Curzon Dax. Curzon sized her up in about twenty seconds, and made the next two weeks the most miserable of her life. She cried herself to sleep every night. She hated him for it. But when the field training was over and she learned about Curzon's recommendation to terminate her from the program, she went back a different woman. She found her voice and reapplied. She tore through the program with a passion, a vengeance. And in the end the administrators chose her for joining.

Arjin:
How did you wind up with the Dax-symbiont?

Lieutenant Jadzia Dax:
When I found out Curzon was dying, I requested the Dax-symbiont.

Arjin:
And Curzon didn't object?

Lieutenant Jadzia Dax:
No. Then I've never been sure quite why - except, as I've come to know Curzon's dark sense of humor, I have a feeling the irony might have appealed to him.
