Continuity mistake: When the runabout is shot by the Dominion ship, Jake is sitting in the left seat, but when he is thrown off his chair by an explosion, he is on the right seat. (00:09:10)
Continuity mistake: In sickbay, when Nog walks over to Collins, he takes her hand and returns his gold Red Squad pin. In the closeup, Collins has a long, manicured thumbnail, but in the next shots facing Nog, Collins has short fingernails. (00:43:15)
Other mistake: Nog is promoted to Lieutenant Commander but is given the rank insignia of a Lieutenant junior grade.
Chosen answer: No. He's given his name, that's all. Nothing there that might lead to a paradox. If he's gone into detail about his time travelling, that might cause an issue or two, but simply stating his name does nothing.
