Dax : "That's because you don't socialise with them the way I do. Looking back over seven lifetimes, I can't think of a single race I've enjoyed more."
Kira : "Did anyone ever tell you that you have very strange taste?"

Dax : "The Korvat colony. First day of negotiations, I walked out on you, right in the middle of that long-winded speech of yours. You should have seen the look on your face. Nobody had ever had the kajunpak't to show their back to the great Kang before Curzon did."
Kang : "I almost killed Curzon that day."

"You can make your own decisions, or you can let these prophecies make them for you." - Dax to Sisko

"I've lived seven lifetimes, and I have never had a friend quite like you." - Dax to Sisko

Dax : "It's funny, a year ago if you'd done something like this, I would have thought you were just trying to be a hero."
Bashir : "And now?"
Dax : "Now that I know you better, I realise it was just a really stupid thing to do."

"If I were in your shoes I would be looking for someone a little more entertaining, a little more fun, and maybe even a little more attainable." - Dax to Worf; dropping a heavy hint

"You have to realise, there's some things in life you can't control. And one of them is me." - Dax to Worf

Sisko : "You win some, you lose some."
Dax : "You always had problems with the 'lose some' part of that."

"One ship against an entire fleet? That's a helluva plan B!" - Jadzia to Sisko

Worf : "I have a sense of humour. On the Enterprise I was considered to be quite amusing."
Dax : "That must have been one dull ship."
Worf : "That is a joke. I get it. It is not funny, but I get it."

"I had a pretty good idea what this was the moment I laid eyes on it. This confirms it. It's a slab of rock with some writing on it." - Dax to Sisko; analysing his discovery

"Our baby... would've been so beautiful..." - Jadzia to Worf; her last words

Bashir : "The Battle of Thermopylae. Do you know it? Well, it's about a force of Spartans led by King Leonidas, who defend a mountain pass against a vast army of Persians.
Ezri : "What happens then?"
Bashir : "For two days, the Spartans lead a heroic struggle."
Ezri : "Until they're wiped out."
Bashir : "Yes. How'd you know?"
Ezri : "Lucky guess. I take it we'll be the Spartans?"
Bashir : "Fighting to the last man."
Ezri : "Just like the Alamo."
Bashir : "Exactly."
Ezri : "Have you talked to a counsellor about these annihilation fantasies?"
Bashir : "Do you think I should?"
Ezri : "I'll set up a session for you tomorrow."
Bashir : "What about tonight?"
Ezri : "Tonight we defend the pass."
