In this episode, we learn Curzon's cause of death; Arandis killed him by Jamaharon.
At the age of thirteen, Worf was captain of his soccer team. During the championship game he accidentally injured a player that would later die from his injuries.
One of the prospective intruders Fullerton mentions is the Borg. It would not be long after the events of this episode that the Borg would attack the Federation during the events of Star Trek: First Contact.
Goof: In all the exterior shots of the Risian buildings, not once did the waterfall appear to be moving. Not even the sudden downpour of rain after the weather system went offline was enough to get it to fall.
Nitpick: Fullerton says that because of all the creature comforts like replicators, Federation citizens have become an easy target for the Klingons, the Borg, the Dominion etc. Yet without replicators to instantly create meals, those citizens would be spending a good portion of their days growing, buying and preparing food to eat at the expense of other activities like starship building and weapon research to fight these threats.
Nitpick: Arandis says she killed Curzon by Jamaharon. This however contradicts what was shown in flashback in "Emissary". In the flashback, Curzon was very much still alive as the Dax symbiote was transferred to Jadzia. His dying clearly wasn't as quick as is suggested here, as there was time to find a new Trill host and a Trill medical facility to carry out the procedure, which would most likely have been on Trill itself.
Nitpick: Apparently, Quark wouldn't give Leeta time off to go to Risa unless he could go as well. However, the Guild of Restaurant and Casino Employees union that Leeta and the other bar staff joined in "Bar Association" should have put an end to such blackmail.
We learn that the Ferengi have 178 words for rain.
Sisko: Isn't there any way for the two of you to... you know...
Dax: Make love?
Sisko:...without injuring yourselves?
Dax: Interspecies romance isn't without its dangers. That's part of the fun.
Sisko: I really wish I was going with you. Dax and I had some great times on Risa! (Jadzia laughs, Worf glares with jealousy) Curzon Dax!
Worf: Curzon. Of course.
Worf: (to Bashir) Do not hug me!
Quark: I have a little present for everyone. (reaches into the bag and begins handing out horga'hns to Bashir, Leeta, and Dax) One for you, one for you, one for you... (reaches Worf) And none for you.
(commenting about Julian and Leeta's break-up ceremony)
Quark: That's it?
Julian: That's it. What were you expecting?
Quark: I was expecting fireworks. Where's the anger? The vicious name-calling? The irrational accusations? I never would have agreed to be a witness if I'd known you were going to be so civil. It's disgusting.
Risan woman: You seek jamaharon?
Quark: I seek whatever you've got.
Risan woman: All that is ours is yours.
Quark: I'll take it.
Worf: The uplink. Give it to me.
Fullerton: Mister Worf, I suggest you all get off this planet as soon as possible. I have no wish to see you or your friends harmed.
Jadzia: Give us the uplink or the only person who'll be harmed is you.
Fullerton: I thought you were one of us.
Worf: Perhaps I was... for a time. But I believe the Federation will survive the Dominion, the Cardassians, the Borg... and even people like you.
Jadzia: As a Starfleet officer, I have the authority to arrest you for what you just did.
Fullerton: But that would be a waste of time. We both know the Risians won't prosecute. They don't have the courage for it. Believe me, I wish they did. (turns his attention to Worf) What did you think of our little demonstration, Commander Worf?
Worf: I can't condone what you did.
Fullerton: Maybe not, but I think you understand it.
Worf: A few months ago, when I was commanding the Defiant on a scouting mission into the Gamma Quadrant, we encountered a protostar cluster. A swirling mass of color, set against a background of glowing clouds and burning sky. It was the most beautiful thing I ever saw... until now.
Jadzia: I've got to take you on vacation more often.
Fullerton: That's right. Take a good look. I can only imagine what you must think of me. A middle-aged, ponderous academic, sweating under the hot Risian suns, wasting his time telling you things you don't want to hear. But you know what I see when I look at you? Children. Pampered, spoiled children. Somehow the citizens of the Federation have come to believe that they're entitled to lives of ease and privilege. If you want something to eat, you get it from a replicator. If you want amusement, you go to a holosuite. And if you need protection, you call for Starfleet. But someday, someday soon, you're going to have to learn to take care of yourselves. Because if I see you as helpless children, then how do you think the Borg see you? Or the Romulans or the Cardassians? Or the Klingons or the Dominion? These empires look at the Federation and they see a prize, a prize we've forgotten how to protect. And if we don't change our ways, they're going to take it from us.
(talking about Curzon)
Arandis: We had a wonderful time. Until I killed him.
Worf: Killed him?
Arandis: Death by jamaharon. (to Dax) I suppose there are worse ways to go.
Jadzia: (reassuring) Trust me. He died happy.
Arandis: He was a very sweet old man.
Worf: I'll take your word for it.
Fullerton: The way I see it, we've got two options. We can either turn our back on childish things and re-embrace the hard work that built the Federation in the first place... or we can lie here, napping in the sun, until we wake up with Jem'Hadar guns to our heads. The choice is ours. Heaven help us if we make the wrong one.
Worf: Tell the Ferengi to return to his cabin.
Quark: You call that a cabin? It's a cot and a waste disposal unit. It's so small, even I can't stand up in there. Look. I'm developing a slouch!
Worf: Tell the Ferengi to return to his cabin now!
Worf: I am looking forward to spending some time alone with Lieutenant Commander Dax.
Jadzia: Isn't he sweet?
Odo: So, what do you think of the O'Briens' plan to name their baby Sean?
Sisko: Hm, I kind of like it. 'Sean'. Has a nice ring to it.
Odo: Except in Bajoran 'Sean' means 'swamp'.
Cirroc Lofton (Jake Sisko), Colm Meaney (Chief O'Brien) and Nana Visitor (Major Kira) do not appear in this episode.
During the filming of this episode, Nana Visitor gave birth to her and Alexander Siddig's son, Django.
This was reputedly the writers' least favorite episode of the show.
Let He Who Is Without Sin...
The episode's title is from the teachings of Jesus in the Bible. A group of people are about to stone an adulteress, and Jesus tells the people, "Let he who is without sin cast the first stone." No one present feels they can make that claim except Jesus, who says he will not harm the woman, but instead forgives her for her sin and tells her to sin no more in the future. This story is told in John 8:2-11.
