Osden might be intelligent, but his training was sketchy and his personality was disastrous. He had been sent only on account of his singular gift, the power of empathy: properly speaking, of wide-range bioempathic receptivity. His talent wasn't species-specific; he could pick up emo­tion or sentience from anything that felt He could share lust with a white rat, pain with a squashed cockroach, and phototropy with a moth. On an alien world, the Authority had decided, it would be useful to know if anything nearby is sentient, and if so, what its feelings towards you are. Osden's title was a new one: he was the team's Sensor.

"What is emotion, Osden?" Haito Tomiko asked him one day in the main cabin, trying to make some rapport with him for once. "What is it, exactly, that you pick up with your empathic sensitivity?"

"Muck," the man answered in his high, exasperated voice. "The psychic excreta of the animal kingdom. I wade through your feces."

"I was trying," she said, "to learn some facts." She thought her tone was admirably calm.

"You weren't after facts. You were trying to get at me. With some fear, some curiosity, and a great deal of distaste. The way you might poke a dead dog to see the maggots crawl. Will you understand once and for all that I don't want to be got at, that I want to be left alone?" His skin was mottled with red and violet, his voice had risen. "Go roll in your own dung you yellow bitch!" he shouted at her silence.

"Calm down," she said, still quietly, but she left him at once and went to her cabin. Of course he had been right about her motives; her question had been largely a pretext, a mere effort to interest him. But what harm in that? Did not that effort imply respect for the other? At the moment of asking the question she had felt at most a slight distrust of him; she had mostly felt sorry for him, the poor arrogant venomous bastard, Mr. No-Skin as Olleroo called him. What did he expect, the way he acted? Love?
