“It oxidises the sulphur.”
“And?”
“And denitrifies.”
“Which is?”
“Nitrates into nitrogen. From the ground into the air.”
“Very good. A very useful microbe, that.”
So Sax forced him to pay attention to the moment, but the price was high. He found himself exhausted at midday when school was over, it was hard to do things in the afternoon. Then they asked him to give more marrow for Simon, who lay in the hospital mute and embarrassed, his eyes apologising to Nirgal, who steeled himself to smile, to put his fingers around Simon’s bamboo forearm. “It’s all right,” he said cheerily, and lay down. Although surely Simon was doing something wrong, was weak or lazy or somehow wanted to be sick. There was no other way to explain it. They stuck the needle in Nirgal’s arm and it went numb. Stuck the IV needle in the back of his hand and after a while it too went numb. He lay back, part of the fabric of the hospital, trying to go as numb as he could. Part of him could feel the big marrow needle, pushing against his upper arm bone. No pain, no feeling in his flesh at all, just a pressure on the bone. Then it let up, and he knew the needle had penetrated to the soft inside of his bone.
This time the process did not help at all. Simon was useless—he stayed in the hospital continually. Nirgal visited him there from time to time, and they played a weather game on Simon’s screen, tapping buttons for dice rolls, and exclaiming when the roll of one or twelve cast them abruptly onto another quadrant of Mars, one with a whole new climate. Simon’s laugh, never more than a chuckle, had diminished now to just a little smile.
Nirgal’s arm hurt, and he slept poorly, tossing through the nights and waking hot and sweaty, and frightened for no reason. Then one night Hiroko woke him from the depths of slumber, and led him down the winding staircase and over to the hospital. He leaned groggily against her, unable to wake fully. She was as impassive as ever, but had her arm. around his shoulders, holding him with surprising strength. When they passed Ann sitting in the hospital’s outer room something in the slope of Ann’s shoulders caused Nirgal to wonder why Hiroko was here in the village at night, and he struggled to wake fully, touched by dread.
The hospital’s bedroom was overlit, sharp-edged, pulsing as if glories were trying to burst out of every thing. Simon lay with his head on a white pillow. His skin was pale and waxy. He looked a thousand years old.
He turned his head and saw Nirgal. His dark eyes searched Nirgal’s face with a hungry look, as if he were trying to find a way into Nirgal—a way to jump across into him. Nirgal shivered and held the dark intense gaze, thinking okay, come into me. Do it if you want. Do it.
But there was no way across. They both saw that. They both relaxed. A little smile passed over Simon’s face, and he reached over with an effort and held Nirgal’s hand. Now his eyes darted back and forth, searching Nirgal’s face with a completely different expression, as if he were trying to find words that would help Nirgal in the years to come, that would pass across whatever it was that Simon had learned.
But that too was impossible. Again they both saw it. He would have to give Nirgal to his fate, whatever it was. There was no way to help. “Be good,” he whispered finally, and Hiroko led Nirgal out of the room. She took him through the dark back up to his room, and he fell into a deep sleep. Simon died sometime during the night.
It was the first funeral in Zygote, and the first for all the children. But the adults knew what to do. They met in one of the greenhouses, among the work benches, and sat in a circle around the long box holding Simon’s body. They passed around a flask of rice liquor, and everyone filled their neighbour’s cup. They drank the fiery stuff down, and the old ones walked around the box holding hands, and then they sat in a knot around Ann and Peter. Maya and Nadia sat by Ann with their arms around her shoulders. Ann appeared stunned, Peter disconsolate. Jurgen and Maya told stories about Simon’s legendary taciturnity. “One time,” Maya said, “we were in a rover and an oxygen canister blew out and knocked a hole in the cabin roof, and we were all running around screaming and Simon had been outside and he picked up a rock just the right size, jumped up, dropped it in the hole and plugged it. And afterward we were all talking like crazy people, and working to make a real plug, and suddenly we realised Simon still hadn’t said anything, and we all stopped working and looked at him, and he said, ‘That was close’!”
They laughed. Vlad said, “Or remember the time we gave out mock awards in Underhill, and Simon got one for best video, and he went up to accept the award and said ‘Thank you,’ and started to return to his seat, and then he stopped and went back up to the podium, as if something had occurred to him to say, you know, which got our attention naturally, and he cleared his throat and said ‘Thank you very much’!”
Ann almost laughed at that, and stood, and led them out into the frigid air. The old ones carried the box down to the beach, and everyone else followed. It was snowing through mist when they took his body out and buried it deep in the sand, just above the wave’s high water mark. They slid the board out of the top of the long box and burned Simon’s name onto it with Nadia’s soldering iron, and stuck the board in the first dune. Now Simon would be part of the carbon cycle, food for bacteria and crabs and then sandpipers and gulls, thus slowly melting into the biomass under the dome. This was how one was buried. And sure, part of it was comforting; to spread out into one’s world, to disperse into it. But to end as a self, to go away …
And here they all were walking under the dim dome, having buried Simon in suffocating sand, trying to behave as if reality had not suddenly ripped apart and snatched one of them away. Nirgal couldn’t believe it. They straggled back into the village blowing on their hands, talking in subdued voices. Nirgal drew near Vlad and Ursula, longing for reassurance of some kind. Ursula was sad, and Vlad was trying to cheer her up. “He lived more than a hundred years, we can’t go around thinking his death was premature, or it makes a mockery of all those poor people who died at fifty, or twenty, or one.”
“But it was still premature,” Ursula said stubbornly. “With the treatments, who knows? He might have lived a thousand years.”
“I’m not so sure. It looks to me like the treatments are not in fact penetrating to every part of our bodies. And with all the radiation we’ve taken on, we may have more troubles than we thought at first.”
“Maybe. But if we had been at Acheron, with the whole crew, and a bioreactor, and all our facilities, I bet we would have saved him. And then you can’t say how many more years he might have had. I call that premature.”
She went off to be by herself.
That night Nirgal could not sleep at all. He kept feeling the transfusions, seeing every moment of them and imagining that there had been some kind of backwash in the system, so that he had been infected with the disease. Or contaminated by touch alone, why not? Or just by that last look in Simon’s eye! So that he had caught the disease they could not stop, and would die. Stiffen up, go mute, stop and go away. That was death. His heart pounded and a sweat broke through his skin, and he cried with the fear of it. There was no avoiding it; and it was horrible. Horrible no matter when it happened. Horrible that the cycle itself should work the way it did—that it should go round and round and round, while they lived only once and then died forever. Why live at all? It was too strange, too horrible. And so he shivered through the long night, his mind gone cyclonic with the fear of death.
After that he found it extremely hard to concentrate. He felt as if he was always at a remove from things, as if he had slipped into the white world and could not quite touch the green one.
Hiroko noticed this problem, and suggested he go with Coyote on one of his trips out. Nirgal was shocked by the idea, having never been more than a walk away from Zygote. But Hiroko insisted. He was seven years old, she said, and about to become a man. Time he saw a bit of the surface world.
A few weeks later Coyote dropped by, and when he left again Nirgal was with him, seated in the copilot’s seat of his boulder
