[Aamin Marritza has just been stabbed by Kainon on the promenade]
[holding the rapidly dying Marritza] Why!?! He wasn't Darhe'el!
KKainon
He was Cardassian! That's reason enough!
No. No, it's not.
S1 E19Duet
S1 E20In the Hands of the Prophets
But she's teaching a fundamentally different philosophy—
KOKeiko O'Brien
I'm not teaching any "philosophy." What I'm trying to teach is pure science.
Some might say pure science taught without a spiritual context is a philosophy, Mrs O'Brien.
What do you know about the murder of Ensign Aquino?
You wound me. All these years together, I thought you knew me. Odo, I am not a killer!
No, but most of your friends are.
True, and I would gladly sell one of them to you if I could. But unfortunately, none of them have taken credit for the death of the Starfleet officer.
Keep your ears open.
Are you kidding? That's the Seventh Rule of Acquisition.
WWinn
You live without a soul, Commander. You and your Federation exist in a universe of darkness and you would drag us in there with you. But we will not go.
You have just made your first mistake, Vedek.
WWinn
Have I?
The Bajorans who have lived with us on this station, who have worked with us for months, who helped us move this station to protect the wormhole, who joined us to explore the Gamma Quadrant, who have begun to build the future of Bajor with us—these people know that we are neither the enemy nor the devil. We don't always agree. We have some damn good fights, in fact. But we always come away from them with a little better understanding and appreciation of the other. You won't succeed here. The school will reopen. And when your rhetoric gets old, the Bajoran parents will bring their children back.
Commander, I heard what you said to Vedek Winn at the school. I just wanted you to know you were right what you said about the Bajorans, at least about me. I don't think you're the devil.
Maybe we have made some progress after all.
S2 E1The Homecoming
Must I remind you of the 76th Rule of Acquisition?
Uh, 76th...
“Every once in a while, declare peace. It confuses the hell out of your enemies.”
S2 E2The Circle
[after Quark informs Odo that The Circle is being supplied with weapons from the Kressari and Odo tells him to get more information]
Quark, I hate to do this, but I guess I'll have to—
That's not fair!
I haven't done anything yet.
Whatever you're going to do, it's not fair.
You're a deputy.
It's not— What?!
You're a deputy. I want you to find out where the weapons are going on Bajor. Meanwhile, I'm going to find out exactly where they're coming from.
You and me, a team?
That's right.
[Quark bellows his head off with laughter, then sobers and hastily turns to leave.]
Goodbye.
Either that, or I'm putting you in a cell.
That's not fair. On what charge?
Impeding an investigation. Unless you want to reveal the identities of the people you've been talking to.
You know I can't do that.
It's your choice. You're a deputy or you're a prisoner.
[with fake enthusiasm] I'm a deputy.
S2 E3The Siege
[Quark is pushing a heavy chest down the access tunnel]
Quark, leave it!
I can't leave it—it's all that I have. My personal mementos, my family album—
It's full of gold-pressed latinum, and you know it.
Who told you?
Your mother did, the day you were born.
[An outraged Quark shoves the chest aside and speed-crawls down the tunnel until he's nose-to-nose with Bashir]
NEVER MAKE FUN OF A FERENGI'S MOTHER. Rule of Acquisition Number 31!
[N.B. In the published companion book, the complete rule is, "Never make fun of a Ferengi's mother. Insult something he cares about instead."]
Without navigational sensors—
We'll have to fly by the seat of our pants.
Great! Seat-of-pants technology.
You Starfleet types are too dependent on gadgets and gizmos. You lose your natural instincts for survival.
My natural instincts for survival told me not to climb aboard this thing. I'd say they're functioning pretty well.
That's a very personal question.
DDax
I'm sorry, but after seven lifetimes, impersonal questions aren't much fun anymore.
[scared by a crawling animal] Oh! Whoa! What's that?! Is that a spider or a dog?
Palucko. The Bajoran moons are full of them.
Oh. I suppose you used to make them your pets, and sing songs about them ‘round the campfire.
No. We used to eat 'em.
I've been a mother three times and a father twice.
Which was easier?
Actually, I wasn't very successful either way.
LNLi Nalas
I'd die for my people, but…
Sure, you would. Dying gets you off the hook. Question is, are you willing to live for your people? Live the role they want you to play? That's what they need from you right now.
GKGeneral Krim
[to Sisko and Nalas] I'm returning to the surface immediately to consult with the Ministers. I expect I will be asked to resign. Commander, since the provisional government has prevailed, I believe it is appropriate to return the command of this station to Starfleet. Well fought, sir.
