KELSEY: Who are you?
PICARD: My name is Mot. I'm the barber.

Mot actually only made two on-screen appearances (three if you count cut scenes), which surprised me. There were a few other Bolian barbers seen in other episodes, it's unknown if any of them were supposed to be Mot.

TROI: They haven't tried to communicate with the outside.
RIKER: No demands, no political statements, no theft. They must want something.

I can't imagine anything here is worthy of theft (except Data, of course). I can't imagine how this would be a good chance to make a political statement. So blackmail or ransom would be the obvious reason.

CRUSHER: I've adjusted the optical transducer in his visor to block some of the pain receptors in his brain.

For once the Treknobabble makes sense. A transducer is something that converts energy from one form into another. All sound devices, antennas, and sensors contain them.

How Crusher did this without tools is a surprise. I can't imagine that the VISOR has styluses stored inside to manipulate the circuitry.

PICARD: I would rather destroy the ship than allow that material to fall into the hands of terrorists.
KELSEY: What makes you think I'm a terrorist?
PICARD: Trilithium resin is a highly toxic waste product produced by our engines.
PICARD [OC]: It's only possible use could be as a weapon.

That's sure the only use that Sisko found for it.

KIROS [OC]: I have Mott.
KELSEY: Is he alive?
KIROS [OC]: Yes.

I think you mean, "Who's Mott? We're looking for Mot!" Sorry, but after his earlier quips I had to take a potshot at Chakoteya.

KELSEY: I'm not a terrorist Captain, nor do I have a political agenda, although I know some people who do have agendas. And they are very interested in this little container.
PICARD: Profit. This is all about profit.
KELSEY: I prefer to think of it as commerce.

The whole "I prefer to call it something not quite as offensive" thing is a cliche that needs to be eliminated from the writer's handbook. There's only so many ways to do it well, and that usually requires a pun or other double-meaning. You can't play it straight anymore and extract any entertainment from it.

WORF: Captain, you keep a saddle on board?
RIKER: Mister Worf, I'm surprised at you.
CRUSHER: Anyone who is an experienced rider naturally has his own saddle.
TROI: It's perfectly normal.

Actually, of anyone on board I would expect Worf to understand the importance of a saddle. Klingons would have their own equivalent to a horse that is still used in battles, wouldn't they?

Memory Alpha

* It's pointed out that Archer and McCoy also failed to learn the nerve pinch post mind-meld.
* The difference between the trilithium of Generations and the trilithium resin of this episode is discussed.

Nitpicker's Guide

* Why doesn't Picard head for a shuttlebay or the Captain's Yacht? In the Yacht's (AKA the Callipso's) case I would have to imagine that the launch sequence requires a lot more assistance from outside to undock the ship.
* Phil is confused about the humor from Worf's final "of course", his only theory is that it's a Mr. Ed joke. It's just Worf being deadpan and going along with his captain, you don't need to overthink it, Phil!
* The Tarellians are mentioned, a race that was last seen in "Haven" and consisting of a small group of Typhoid Marys that Wyatt was trying to help. I'll have to assume that they're not the same race.
* Someone messed up the digits in the stardate, because otherwise somehow Worf escaped the Romulan prison camp for one mission before being sent back.
* One of the weapons the thieves used is a Varon T disruptor, last seen in "The Most Toys" as something that only one of exists outside of Fajo's collection. It's a surprise that a common thief would be using such a weapon for a simple theft.
