Maybe the soulless minions of orthodoxy finally caught up with him.
S5 E25In the Cards
You turned me over to these soulless minions of orthodoxy.
[Working for a scientist named Geiger, and also searching for a missing teddy bear]
We're going to beard the lion in its den.
[Confused] Lions, Geigers, bears...
Oh, my.
Even in the darkest moments, you can always find something that will make you smile.
S5 E26Call to Arms
[to Sisko] Would you marry me? I mean us. I mean, would you perform our wedding ceremony?
Just don't forget the 190th Rule of Acquisition.
"Hear all, trust nothing." Good advice, sir.
You'd shoot a man in the back?
Well, it's the safest way, isn't it?
[upon learning the Federation is mining the entrance to the wormhole, the Dominion despatches Weyoun to deliver an ultimatum]
What can I do for you, Weyoun?
[brusque, with none of his previous obsequiousness] Captain Sisko, I'll keep this brief. We know all about the minefield.
I assumed you'd find out sooner or later.
As I see it, you have two choices. Either you remove the mines...or we will take this station from you and remove them ourselves.
[contacting Sisko from the flagship of a Dominion fleet moving to attack Deep Space Nine] Captain Sisko, I don't suppose you'd like to surrender and avoid unnecessary bloodshed?
Absolutely not. [Dukat grins]
I was hoping you'd say that.
When I first took command of this post, all I wanted was to be somewhere else—anywhere but here. But now, five years later, this has become my home, and you have become my family. And leaving this station—leaving you—is one of the hardest things I've ever had to do. But this war isn't over yet. I want you to know that while we were keeping the Dominion occupied, a Starfleet-Klingon task force crossed the border into Cardassia and destroyed the Dominion shipyards on Torros III. Your sacrifices, our sacrifices made that victory possible. But no victory can make this moment any easier for me. And I promise, I will not rest until I stand with you again—here—in this place where I belong.
All I know is that any marriage where the female is allowed to speak and wear clothing is doomed to failure.
It would appear Captain Sisko removed or destroyed everything of value.
[Noticing Sisko's baseball] Not everything.
What is that?
A message from Sisko.
I don't understand.
He's letting me know... he'll be back.
S6 E1A Time to Stand
Are you so deluded, you actually believe that we're going to have some sort of intimate relationship?
We already do.
You're not genetically engineered. You're a Vulcan.
If I'm a Vulcan, then how do you explain my boyish smile?
Not so boyish anymore, Doctor.
First we shed blood, then we feast.
As it should be.
