Jadzia Dax: I know how much your career means to you.

Worf: You come first – before career, before duty, before anything. I do not regret what I did; and I would do it again.

Jadzia Dax: I don’t know what to say.

Worf: You could say ‘thank you for saving my life’.

Jadzia Dax: Thank you for saving my life.

Worf: And you could say ‘I would do the same for you, Worf’.

Jadzia Dax: Well – I’d have to think about that. My career is very important to me, you know.
