"Can I see it? Can I meet your brother?"

"He's dead. He died, oh, forty years ago. He had an equipment failure, out on the Yuon desert, on Dothog. Air ran out. I've got the picture, though. I'll bring it."

"I'm sorry, Sagot."

"Child, you grieve and you get over things. I just remember my brother now, not the end of him, just the living. You know the shuttleport, just outside Dsonan? You can feel the ships take off. You can hear them when they come in, like thunder, even through the walls-"

"Is that that sound?" ("Duun, what's that?" "I don't know, buildings have a lot of sounds. Mind on your business, minnow.")

"-about every five-day. They carry cargo up to the station, pick up what the station makes, medicines and such, and bring it back down. There's still the Dothog base, it's quite a little town now, all domes and connecting tunnels. All scientists. About once a year you can get a tour out from the station, but it's horrendously expensive, the kind of thing only the rich can afford and too rough to please most of that sort, but they still have a few visitors. I've dreamed about it, I'd like to go, but it takes a year each way; and something always comes up. I don't know-" Sagot looked at her hands and looked up. "I think, I think deep down I'm superstitious about it, I think my brother's still there, still climbing about over the dunes and enjoying himself, but if I went there it'd be just a place, I'd see the town all grown up and the damn tourists and I'd go out in the desert and he wouldn't be there. Then he'd be dead for me, really dead-oh, gods. I'm sorry, boy, the old woman talks on and on. You wanted to ask me about space."

"Have you been there?"

"I've been up to the station. It's a barren kind of place, all tubes and tunnels-"

(Tunnels. Metal tunnels. Going on and on, bending up when you walk them-)

"-and one part of it looks a lot like all the other parts. And strangely enough you don't really get to see the stars much. You can see them from the shuttle if you get up front-they let you do that. It's beautiful. The world's beautiful. Haven't you seen it in pictures?"

(The dark globe with the fire coming over it, the spinning place-)

"No, of course you haven't. I've got this marvelous window-tape. I bought it on the station. It's the earth from space. I think I can find a copy for you. You get to watch the sun come up over and over again round the curve of the world; you get to see all the seas and the clouds all swirled-"

"He's coming round-he's coming round. Hold the injection. He's coming out of it."

"That jolted him. Something happened."

"Quiet. He can hear. Let's get him out of here."

"Do you hear us, Thorn? Move your hand if you hear us."

"Aaaaaaaaiiiiii!"

It was his voice. Thorn was the one screaming. He came fighting up out of the dark, and dark was about him, stars aglow in giddy distance.

Light blazed, white and awful; he flung himself out of bed blind and hit the wall with his back before he saw Duun in the doorway, against the dark of the hall, Duun naked from his sleep and staring at him. "Are you all right, Thorn?"

Thorn leaned against the cold surface at his back. His limbs began to shake in aborted reaction. "I'm sorry, Duun."

Duun kept on staring at him. Duun's ears were back. Thorn peeled himself off the wall. The windows were sunrise now, sun coming up over grasslands. Duun had disrupted the timer. The air-conditioner wafted grass-scent, dewy and cold. Thorn shivered again, feeling the draft on his skin. Bedclothes made a trail over the side of the bed and onto the sand, the route his flight had taken.

"It was a nightmare," Thorn said. "I dreamed…" (Faces. Sounds.) He began to shake again. "Faces like mine, Duun-they didn't make me up!"

Duun said nothing. His face had that masklike look that it had when he was not going to say anything.

"Did they?" Thorn persisted.

"Who said they didn't make the tapes up?"

"Don't do this to me, Duun!"

"You don't sound sleepy. You want a cup of tea, a bit to eat?"

Thorn surrendered. Duun was being kind. Duun was leading him off again. Thorn knew the tricks. He ripped the sandy bedclothes loose and threw them down on the floor. The bed wanted turning and thumping anyway, and the blankets could use washing. Duun had left the door and left it open. Thorn pulled the bin open in the side of the riser and took out yesterday's clothes, but it was before baths and he had to dress again before class.

Duun was in the kitchen when he came in, setting the teapot on the riser. "Sobasi?"

"It's all right." The microwave was busy. It went off and Thorn pulled the plates out and set them on the table. (Faces. Faces. The station. Ships coming and going. Dots and symbols. Chemistry. The value of pi. Numbers.) Thorn sat down and swung his legs about, crossed; Duun did the same and poured tea for himself. "I drink too much of this stuff," Duun said, "it ruins my sleep."

"So do I. Duun, can we talk about it-once?"

Duun's ears went flat.

"Dammit, please!"

Duun held out the teapot to him with a bland look on his face. "One question. I'll listen to it. Only one, Haras-hatani. You don't have to ask it now if you want to think about it. Snap judgment's never good."

Thorn took the teapot, composed his face and poured. (I hate him. I hate him. He hasn't got a nerve in his body.) "I'll tell you when I ask it: I don't want you taking the first question I ask and claiming that lets you off. Have you got a lover?"

(Got him.) Duun's ears flicked; the eyes dilated and contracted. "Was that the nightmare?"

"No. I'm just curious."

"None now. A companion for a while. I sent her off." Duun filled his mouth and swallowed.

"Why?"

(Another strike. I hadn't thought that.) "She would have wanted marriage eventually. I didn't."

"How old are you?"

"Minnow, when you started this, we were talking about one question. Is this all pertinent?"

"You were onto me yesterday because I always take the defensive; attack sometimes, you said. I realize I do that even outside the gym. So I'm attacking. Do you think you're old?"

Duun grinned. "You'll go too far pretty soon, Haras-hatani, and I'll call this game. Do you think I'm old?"

"What was your solution for the government?"

"To make you hatani. Which I've done."

"Why didn't you want me to learn about the world the way it is?"

"You have now, haven't you?" Duun shrugged. (Gods, not a flicker.) "It never came up; too much of Sheon and too little of the world. When we came here-two years early, and not quite my planning, I might remind you-" (Counterattack and hit.) "You were pretty badly shaken, if you'll recall, and you knew too damn much you were unusual." (Hit again. Gods! he's got no mercy.) "What was I going to do? Throw the world at you in a day? Listen, minnow, I had a problem on my hands, I had a boy to bring up without newscasts, without pictures of cities, without any hint what went on outside Sheon's woods, because any photograph with people in it was going to show a smart young lad that people all look a lot like me and none of them like you. I had to educate you without educating you, if you see the problem, because I didn't want you to suffer with your difference. I wanted to give you a childhood, and I gave you the best one I knew: I gave you mine."

(He's working on me. He's telling the truth. What was the experiment? They're not done with it. It's still going on.) Thorn felt sweat gather in the folds of his knees and beneath his arms.

"You have to admit," Duun said, "the last two years there's been a lot poured into your head. A lot of facts. You've come from the past to the present. I'll tell you: when I started I didn't know what your mental capacity might be, whether it was normal, you understand. I didn't know whether I could do what I planned. I had to know that before I let anyone else set hands on you… whether you could be hatani. Remember Ehonin's daughter."
