The Cardassian warship is in visual range. On screen. They're headed right to it. Well, they've got to listen to reason, haven't they? When we warn them what could happen if they go in there. Doctor, most people, in my experience wouldn't know reason if it walked up and shook their hand. You can count Gul Dukat among them.
Kira, Dax, Odo and Bashir chase after head to the wormhole, but find that Gul Dukat is doing the same.
