General K'Vagh:  Fleet Admiral Krell will not extend his deadline .
Dr. Phlox: The only possible way to get results on Krell 's schedule is to infect four healthy Klingons .
General K'Vagh: You have four right here !
Dr. Phlox: Only one of these strains will work , the other _ three _ will be lethal . Ethically , it 's unthinkable !
General K'Vagh: The ethics , Doctor , are simple : three lives to save millions .
