It wasn't like being a prisoner. The medic brought him plenty of food, urging him to eat—"You need plenty of protein after radiation burns"—and if he stayed in the bunk, it was only because he felt too weak to get up. Actually he was suffering from delayed emotional shock, as well as from radiation. He was content to let things drift.
Inevitably, the time came when he had to think about what he had done. He had betrayed Montano, he had been false to the men who sent him.

"I've done something better than stealing a secret by stealth. I've proved that humans and Lhari can communicate, that they can trust each other. It's only their looks that are strange. A kind, generous man is a kind generous man, whether his name is Raynor Three or Vorongil."
But who's going to know it?
"I know it. And truth comes out, sooner or later. Somehow, a better understanding between man and Lhari will come from this."
Secure in the knowledge, he turned over and went peacefully to sleep.
