Martok orders the Ch'Tang to be brought to a hover 300 meters above the Dominion base and then decloak and fire. In the exterior shot of the ship, it decloaks while swooping in for an attack run, not hovering above the base.

Kor is referred to as the last son of the House of Kor. Houses are named for the father of the family. If Kor has no sons of his own, then the name of the house would not have passed to him, and he would be the last son of the House of Rynar, not the House of Kor.

When Martok, lying on the floor of the Ch'Tang's bridge, draws his d'k tahg (Klingon dagger) to hurl at the delusional Kor, the cross guard of the dagger is already splayed. A d'k tahg is holstered with the cross guard retracted against the blade.

Martok's holster is designed to hold the blade splayed.

After Kor leaves the mess hall, Martok becomes frustrated and swipes away the remains of Kor's meal. He does so while holding a mug of bloodwine he'd been carrying throughout the scene, yet nothing spills out of the mug, even when it is turned sideways, revealing it to have been empty the entire time.

When Kor renders Worf unconscious in the hallway, the sound of the hypospray is heard before it makes contact with Worf's neck.

When Work and Martok are speaking on the Ch'Tang's bridge, just after Worf says that Kor has never met Martok, Martok looks up at him. The scar over his left eye can be seen to move in the same direction as his good, right eye, a result of the movement of JG Hertzler's eye moving beneath the prosthetic scar.

(at around 20 mins) Quark hands a tray with empty glasses across the bar. The tray moves considerably, but the stemmed glasses stay stuck to the tray; they are obviously glued to the tray.

The Klingons aboard the Ch'Tang are presumably speaking Klingonese to one another, with the language translated to English for the audience's benefit. There are a few random phrases, however, that remain untranslated for no discernible reason. If all the spoken language is Klingonese translated to English, then all the language should be translated to English, not just most of it.

When Kor offers his condolences to Worf about Jadzia's death, Worf says that, "She died a warrior." Worf's goal at the beginning of the season was to win a glorious battle in her honor because she did not die a warrior and could not otherwise enter Suto'vo'qor. Her actual death would seem to support the idea that she died a warrior, though, as she died, weapon in hand, facing down a superior-powered enemy.

During the attack run against the base, Martok and Worf, the Ch'Tang's captain and first officer, are both incapacitated. Kor, the third officer, steps up to take command. No mention is made of the second officer, who would be next in the chain of command after Martok and Worf.

The Klingons are being pursued by Jem'Harad ships, who will catch up to them in 2 hours. The Klingons hope to make it to the Starfleet task force waiting for them near DS9, led by the Defiant. It is said they are 3 hours, 45 minutes away from rendezvousing with the Defiant. If they would contact the station and request assistance, some of those Starfleet ships head towards their position and reinforce them before the Jem'Hadar caught up to them. No one has this idea, instead jumping to the conclusion that one of the Klingon ships must engage the Jem'Hadar in a desperate (suicidal) attempt to delay them long enough for the rest of the squadron to hopefully make it back to DS9 before they are caught.

Darok brings a tray of food to Kor's bunk, after having heard Worf's plan to sacrifice himself to save the squadron. Kor says he is not hungry, but Darok tells him that, "The food is for me. I haven't eaten in hours." He then does not eat the food during his conversation with Kor, nor take it with him when he leaves.

Martok says that the difference between Kor's name and his is that Kor's name opens doors while his name closes them. While that may have been true much earlier in his life, Martok is now in command of the entire Klingon war effort, while Kor has no influence left and had to beg Worf to even be allowed to serve on a ship.

When listing the reasons he doesn't think Ezri should pursue a relationship with Worf, Quark neglects a major one: the Trill taboo against re-association. Joined Trills are forbidden from becoming involved with their previous hosts' spouses. The punishment for such a relationship would be exile from Trill society, which would be a death sentence for the Dax symbiont.
