Isabel: "That's what you're up against. And all you've got is one old ship and half of crew to staff her. We need to run. As far and as fast as we can."
One crew member starts to stand up.
All the crew stand, listening to his speech."
Cutter looks at Isabel with a commanding gaze.
Cutter smacks the table. The ship is brought up to Red Alert status.
The crew starts working again and a siren can be heard. Isabel looks around the bridge, stunned to see the crew is fully prepared for battle.
