Goof: When Nog enters the forward section of the runabout, just before he and Jake leave the Starbase, the rear compartment's doors close behind him. Then, as the Jem'Hadar fighters approach, the door is open.
Nitpick: Dorian Collins says she is from Tycho City on Luna (the Moon). She pronounces it "tie-ko", but it is actually pronounced "tee-koo" because Tycho Crater is named after Tycho Brahe, the Danish astronomer who discovered it.
Nitpick: What happened to the official diplomatic message from the Federation Council to the Grand Nagus? Did Nog just forget about it?
Some of the Valiant crew must be pulling double duties due to personel shortages. Collins also works in the sickbay.
Nitpick: Nog must be quite the medical observer. He tells Collins that everyone was dead on the bridge, without checking a single person.
Goof: In several exterior shots of the Valiant, the Defiant's NX-74205 registry can be seen on the hull instead of Valiant's NCC-74210.
Goof: When Nog takes evasive action in the runabout to avoid the Jem'Hader fighters, the front of the runabout set where the front windows were removed for filming can be seen as the camera swings to simulate the movement of the ship.
Nitpick: Why did the Valiant have an acting Chief Petty Officer? A CPO is a non-commissioned officer. A non-com is an officer who is given a position of authority by a commissioned officer, like Chief O'Brien. None of the other Red Squad cadets had finished their Academy training, but all had ranks of commissioned officers. Collins was a Starfleet cadet as well, and therefore shouldn't be the only one with a non-com rank.
Goof: Nog is promoted to Lieutenant Commander by the Red Squad captain, but his rank pips only show him to be a Lieutenant.
Jake: If we keep going in this direction, we'll run into Cardassia Prime. And that won't be any fun at all.
Jake: I don't even know who you are anymore.
Nog: I'm the chief engineer of the starship Valiant.
Jake: I'll have them put that on your tombstone.
Collins: You know, the sun only comes up once a month on the Moon. Every lunar morning, my father and I would put on suits and... hike out across the Sea of Clouds. We'd stop at this collection of boulders on the western rim and wait for the sun to come up. Dawn is so... shocking on the Moon. One minute you're in the darkest night you can imagine, and then in the next instant, the sun lifts up and this glorious, pure light just explodes across the surface. I felt like I met God every morning.
Nog: You gonna write a story about all this?
Nog: What are you going to say?
Jake: What do you think I should say?
Nog: That it was a good ship, with a good crew, that made a mistake. We let ourselves blindly follow Captain Watters, and he led us over a cliff.
Collins: That's not true. Captain Watters was a great man.
Jake: Dorian, he got eveyone killed.
Collins: If he failed, it was because we failed him.
Nog: (to Jake) Put that in your story too. Let people read it, decide for themselves. (to Collins, as he gives her his Red Squad insignia) He may have been a hero. He may have even been a great man. But in the end, he was a bad captain.
Nog: You don't understand because you've never put on one of these uniforms. You don't know anything about duty or honor or sacrifice or any of the things that make up a soldier's life. I'm part of something larger than myself. All you care about is you.
Jake: That's right! I care about Jake Sisko and whether or not he's going to be killed by a bunch of delusional fanatics looking for martyrdom!
Jake: Can I say something?
Farris: You are not a member of this crew!
Watters: Let him speak.
Jake: You probably all know who my father is - Benjamin Sisko. So you know I'm not exaggerating when I say that he's considered to be one of the best combat officers in the fleet. And I'm telling you right now that even with the entire crew of the Defiant with him... my father would never try to pull off something like this. And if he can't do it... it can't be done.
Watters: We're Red Squad, and we can do anything!
Watters: We've had to maintain strict radio silence ever since the war began. The orders were addressed to Captain Ramirez, but since he's dead, the mission is now mine. And make no mistake, I will carry out that mission... or die trying.
Collins: (to Jake) We're all supposed to be leaders - that's what the Academy trains us to be. No, Tim Watters is more than that, he's... he's the captain.
Jake: I don't get to see the Nagus?
Nog: Now, why would you want to see the Nagus?
Jake: My father asked me to... say hello and... to give the Nagus his best wishes.
Nog: You'll have to do better than that.
Odo: Having a bad day?
Quark: Like you care.
The Valiant tracks a Dominion battleship traveling at warp 4.7, and the First Officer looks at a display labeled "Fwd Targeting Scanners 4751". Writer Joe Menosky began including references to the number 47 in almost every episode of Star Trek since season four of The Next Generation. It is an in-joke, referring to The 47 Society at Pomona College in California, a college which Menosky attended.
This episode marked the final appearance of the runabout USS Shenandoah. As far as we can see, it is left in Dominion space.
Colm Meaney (Chief O'Brien) does not appear in this episode.
David Gallagher reprises his role of Riley Shepard, the Red Squad Cadet from season 4's "Paradise Lost".
When Ira Steven Behr was developing the Defiant, the original name was the Valiant.
The original script was to have Kira with Nog instead of Jake. According to Ronald Moore, Kira was replaced with Nog because "...you couldn't believe that Kira wouldn't kick every one of their asses and take back the ship single-handedly."
The Valiant's motto was: "We set sail on this new sea because there is new knowledge to be gained and new rights to be won." This is a quote from John F. Kennedy.
