Admiral Quinn: "Within less than two weeks under your command, the Cabot science vessel saw an onboard experiment go beyond your control. One crew member was tragically lost, and the ship itself suffered a total and complete structural failure. And, then, of course, a genetically modified species managed to find its way to the surface of Pragine 63, forcing the evacuation of the entire civilization. And we've just gotten word these creatures have made their way into Klingon space. So let's add a diplomatic crisis to all of this. But according to your report, this entire calamity was all caused by one crew member. How do you explain that?"
