"What?"
One of the crewmen came dashing up, his crest sweat-streaked. "Captain! Rugel has collapsed! We don't know what's wrong with him."
"Radiation sickness," said Bart, and Vorongil reached out, catching his shoulder in a cruel taloned grip. Bart said desperately "I'm not a Lhari! I signed on in disguise—I knew they meant to take the ship, but I can't let you all die.
"How can I make you believe me? Here—" In desperation, Bart reached up. Pain stabbed his eyeballs, fierce, blinding, as he pulled out one of the contact lenses. He could not see the captain's face through the light, but suddenly two Lhari were holding his arms. The fear of death was on Bart, but it no longer mattered. He saw through watering eyes the ever-deepening orange of the badge disappearing.
"Here," he said, tearing at it, "radiation. You must be able to see how dark it is. Even if it's just darkness...."
Suddenly Vorongil was shouting, but Bart could not hear. Two men were dragging him along. They hustled him up the ramp of the ship. He could see again, but his eyes were blurred, and he felt sick, colors spinning before his eyes, a nauseated ringing in his head.
