Just watched Tears of the Prophets again, and for seemingly no reason, Sisko leaves both his science officer and helmsman, and his chief medical officer, at home during the biggest allied offensive of the war. Yet he takes Jake and Garak along for the ride. Couldn't he have left Nog in charge of the station? There's no real explanation of why Jadzia doesn't come along, except for "look after the station until I get back, Old Man." Was there a line of dialogue cut? Was it for medical reasons due to the treatment she was having for the pregnancy? It's all very odd and contrived.
