Hilliard: I'm afraid those files are classified.
Bashir: But... I thought you just asked me all these questions to clear me to receive them...
Hilliard: No, no, you misunderstood. I can't release those files to anyone who doesn't have Sigma-9 clearance.
Bashir: Listen, I don't give a damn about Sigma-9 clearance!! All I care about is finding a cure for this disease!!
Hilliard: I fail to see why you're so determined to cure a disease that infects our enemy. We're at war, Doctor.
Bashir: The Founders have nothing to do with it! Odo's life is at stake!!!
Hilliard: Odo, which by your admission, is known to consort with the enemy.
Bashir: (struggles to calm down) Sir, you have to understand the circumstances.
Hilliard: I don't care about circumstances. If you find a cure, there's a good chance it will fall into Dominion hands. That's a risk Starfleet Medical is not willing to take. Request for the files is denied. Now if I were you, I would drop this matter. Otherwise I will have to refer to Starfleet Security.
