As Worf and Jadzia approach the outpost, the craft veers to the left, putting the planet and the moon on the right side of the view screen. However, as Jadzia turns back to the right, the moon slowly moves the right side of the middle of the view screen and then suddenly jumps to the lower left side of the screen.
Although Worf and Dax are supposed to be traveling through 20 kilometers of heavy, primitive, unpopulated jungle terrain to reach the base, at one point Dax looks briefly at a large lizard that is resting on what appears to be a rectangular box or concrete step of some kind; it's obviously man-made and not a rock or other natural formation (if it's supposed to be part of jungle ruins or something, this is never addressed).
As Major Kira said that Worf and Jadzia are the only two left to do the mission, she shouldn't send them away because she knows the Federation rules, not to send family!
At the end Worf is reprimanded by Sisko over this although Major Kira should be reprimanded that she allowed them to go on this mission together.
Instead of Jadzia she should send another officer or send an message to the Federation for assistance.
When Worf leaves Dax they were only 3 kilometers from the rendezvous site, and given that Dax's injury had slowed their pace, Worf was likely set to arrive close to the appointed time. He told Dax that he would be back for her the following night, yet certainly the 6 kilometers roundtrip would take him and the Cardassian defector far less than a full day--likely just a few hours.
It is unlikely that a husband and wife would be allowed to go on a dangerous mission together, for the reasons seen in this episode. Such a policy would have been in place even in the time of Archer. Surely this would not have been the first time that a mission failed because participants put family members before a mission objective.
Worf uses the outdated American pronunciation of kilometers, pronouncing it "KILL-oh-meet-ers" instead of the more universally accepted "kill-Ah-meh-ters." Worf actor Michael Dorn has made this mistake on several occasions dating back to his time on TNG, though he generally pronounces the word correctly, making the few times he does not errors rather than a singular character quirk.
