Plot hole: Earlier in the season, it was established that The Jem'Hadar are genetically engineered to be loyal to the Changelings, meaning they will not deliberately harm them. With that in mind, the Changelings still care about Odo's well being despite his refusal to return to them. So why didn't the Lovok Changeling send a message to The Jem'Hadar ships to inform them that a Changeling was going to be on the runabout? Given that he took time to offer another chance to return to his people, you would think he'd take time to make sure he returned to the station safely.
Suggested correction: Maybe The Jem'Hadar were trying to disable the runabout to try and capture Odo and Garak.
It's Only a Paper Moon - S7-E10
Continuity mistake: When every senior staff officer is in the conference room, watch Dax's rank pips. They change places from a shot to another, going (mentioning from left to right on her collar) from black-gold to gold-black and coming back to black-gold. (00:16:25)
Visible crew/equipment: Just after Leeta and Rom makeup and decide to proceed with their wedding plans, the camera pans up to the Chief and Julian. You can briefly see green tape on the floor indicating where the Chief is supposed to stand.
'Til Death Do Us Part (2) - S7-E18
Continuity mistake: When the Breen fling Dax into the cell after interrogating her, she (the stunt woman) lands front-down, facing her left side, with her left knee raised. (To clarify her body position, if she were vertical, it would appear her left foot was resting on the seat of a chair) The camera angle changes instantly so that we see Worf rush to her side as he kneels on one knee. But that knee is on the ground exactly where Dax's knee should still be. But it isn't, because both her legs are suddenly straight. (00:32:40)
Other mistake: As Kira is showing Ziyal the Federation rifle, the compartment underneath the rifle flips open unintentionally.
Visible crew/equipment: As the Defiant tries to contact the Ulysses, the camera pulls too far back at Odo's station, and we can see the microphone along with the boom pole above the captain's chair. (00:14:40)
Factual error: The United States conducted no nuclear tests in 1947 and conducted none in Nevada until 1951.
Plot hole: Thomas Riker is able to steal the Defiant partially because he's a genetic double for and not a clone of Will Riker. Thomas Riker's existence is not a secret. Star Fleet is aware that the first officer of their flagship has a genetic duplicate who resigned and is out there somewhere. There should be something in place to verify Will's location before giving Thomas access. But then, of course, we wouldn't have an episode.
Suggested correction: At this point Thomas Riker is still a Starfleet officer. There is no need to lock him out of accessing the Defiant's systems as he is considered just as trustworthy as Will.
It's said that he resigned over suspected Maquis sympathies. They were right.
They say that he had expressed political opinions that supported the Maquis, not that he had resigned from Starfleet. A large number of Starfleet officers supported the Maquis' intentions, but still stayed loyal to Starfleet.
No, Thomas Riker accessed the Defiant under the guise of being Will Riker, and Major Kira released the lockouts being under that impression.
Exactly. NOBODY in Star Fleet has thought "Well, what if one of them claims to be the other? How do we tell them apart?"
Other mistake: Nog is promoted to Lieutenant Commander but is given the rank insignia of a Lieutenant junior grade.
Visible crew/equipment: After Kira returns the expensive gift to Zek, when Quark kneels in front of Zek we can see the T-mark on the floor, under the table. (00:23:15)
Continuity mistake: When Kira is explaining to Jadzia in Quark's that she wants to get rid of Sisko, she is wearing her Bajoran earring in her right ear. When she picks Quark up by his collar a couple of shots later, the earring is gone.
Continuity mistake: During Worf's questioning, Worf switched from being a Lt. Commander (2.5) pips and a commander (3) pips several times.
Continuity mistake: In the scene where Dax is being questioned by the Klingon lawyer, Captain Sisko is shown having only 3 pips, or the rank of commander. (00:12:55 - 00:13:25)
What You Leave Behind (2) - S7-E26
Continuity mistake: After Dukat kills Adami, he clutches a large book to his chest with his right arm. Sisko charges at Dukat, who, still clutching the book, turns to face Sisko. When the camera angle changes to show Dukat from behind, he is holding no book - and he wraps his right arm around Sisko as they fall off the cliff. The following overhead shot shows that Dukat still clutches the book (not Sisko) as the two fall into the fire. (The Region 1 'Season 7' DVD set includes this two-parter as a single, longer episode and my timecode is based on this fact). (01:13:45)
Other mistake: Shortly after Quark, Rom and Nog arrive on Earth in the 20th century, just after they are observed through the one-way glass by the Army officers, the Captain in the hat who enters the room with the man in the suit to interrogate the Ferengi is wearing his rank bars on his shirt collar horizontally, parallel to his collar. The two bars of an Army Captain's rank should be worn vertically.
The Way of the Warrior (2) - S4-E2
Character mistake: During the Defiant's flight to save the Cardassian officials, Worf says something to the effect of, "I've never been aboard a Federation ship equipped with a cloak before". However, he was aboard the Enterprise during the Pegasus incident, where The Ship was temporarily equipped with a cloaking device.
Doctor Bashir, I Presume? - S5-E16
Factual error: When Captain Sisko introduced the head of JAG to Bashir's parents, he pronounced "Rear Admiral Bennett" but Bennett was wearing the rank of Admiral (2 X 4 pips enclosed) instead of Rear Admiral (2 X 2 pips enclosed).
Doctor Bashir, I Presume? - S5-E16
Character mistake: In the scene in Sisko's office where he has contacted Rear Admiral Bennett, Bennett says "Two hundred years ago, we tried to improve the species through DNA resequencing, and what did we get for our trouble? The Eugenics Wars." This puts the wars in the 22nd century, and differs from every other mention of them, where they occurred in the late 20th century, not the 22nd century as Bennett implies. (00:39:30 - 00:40:00)
Visible crew/equipment: When Jadzia and Melora are in the runabout talking about relationships, Jadzia mentions having to go back 150 years for a Starfleet relationship; when it cuts to Melora the boom mic can be seen coming in through the front window. (00:23:05)
In the Pale Moonlight - S6-E19
Revealing mistake: As Sisko is threatening Tolar in the simulator, Tolar's prosthetic mask can be seen to bend awkwardly against the wall, as if made of rubber.
