From “In the Pale Moonlight” (DS9 6x19)

Because I posted the video of the last two scenes yesterday and love this one, set on a turbolift, as well. Not only does it have Garak saying “It’s best not to dwell on such minutiae,” but it has Sisko uttering what is always my favorite line of his: “What?!”

Transcript (Source)

Garak: Mind if I join you?

Sisko: Be my guest. (Turbolift door closes.) Ops.

Garak: Hold. The less I’m seen parading through Ops, the better.

Sisko: I couldn’t agree more.

Garak: You seem angry.

Sisko: Who’s watching Tolar?

Garak: I’ve locked him in his quarters. I’ve also left him with the distinct impression that if he attempts to force the door open, it may explode.

Sisko: I hope that’s just an impression.

Garak: It’s best not to dwell on such minutiae. In any case, we have far more important matters to discuss. I’ve located a gentleman willing to sell us a genuine optolythic data rod.

Sisko: How do you know it’s genuine?

Garak: I trust the source, but rest assured I will confirm the rod’s authenticity before I make payment. Which brings me to you.

Sisko: How much does he want?

Garak: I’m afraid he’s not interested in latinum. The gentleman in question has requested to be compensated with two hundred litres of biomimetic gel.

Sisko: What?

Garak: I don’t know why, exactly. One would assume it has something to do with genetic experimentation.

Sisko: Offer him something else.

Garak: Believe me, I wouldn’t be relaying this request if I thought he’d take anything else.

Sisko: Biomimetic gel is strictly controlled by the Federation and not for sale at any price. Find someone else who’s willing sell us a rod.

Garak: I wasn’t exaggerating when I told you about the near impossibility of obtaining a genuine Cardassian data rod. It’s something of a minor miracle that I was able to locate this one source, I’m virtually certain I won’t find another. I’m afraid we either give him what he wants or forget the whole enterprise.

Sisko: Then let’s forget about it. Ops. Hold. Two hundred litres is out of the question. There’s not that much gel in the entire sector.

Garak: I believe the quantity is open to negotiation.

Sisko: Ops.

[And then there’s the scene where Julian is pissed about being asked for the stuff, especially because Sisko can’t tell him why he needs it.]
