in gangs that played separately more often than not. So kissing in the coatroom represented something new, and serious—and the look Nirgal had seen on Jackie and Dao’s faces was so superior, as if they knew something he didn’t—which was true—and it was that which hurt, that exclusion, that knowledge. Especially since he wasn’t that ignorant; he was sure they were lying together, making each other come. They were lovers, their look said it. His laughing beautiful Jackie was no longer his. And in fact never had been.
He slept poorly in the following nights. Jackie’s room was in the shoot beside his, and Dao’s was two in the opposite direction, and every creak of the hanging bridges sounded like footsteps; and sometimes her curved window glowed with flickering orange lamplight. Instead of remaining in his room to be tortured he began to stay up late every night in the common rooms, reading and eavesdropping on the adults.
So he was there when they started talking about Simon’s illness. Simon was Peter’s father, a quiet man who was usually away, on expeditions with Peter’s mother Ann. Now it appeared that he had something they called resistant leukaemia. Vlad and Ursula noticed Nirgal listening, and they tried to reassure him, but Nirgal could see that they weren’t telling him everything. In fact they were regarding him with a strange speculative look. Later he climbed to his high room, got into bed and turned on his lectern, and looked up ‘Leukaemia’ and read the abstract at the start of the entry. A potentially fatal disease, now usually amenable to treatment. Potentially fatal disease—a shocking concept. He tossed uneasily that night, plagued by dreams through the grey bird-chirp dawn. Plants died, animals died, but not people. But they were animals.
The next night he stayed up with the adults again, feeling exhausted and strange. Vlad and Ursula sat down on the floor beside him. They told him that Simon would be helped by a bone marrow transplant, and that he and Nirgal shared a rare type of blood. Neither Ann nor Peter had it, nor any of Nirgal’s brothers or sisters or halves. He had got it through his father, but even his father didn’t have it, not exactly, just him and Simon, in all the sanctuaries. There were only five thousand people in all of the sanctuaries together, and Simon and Nirgal’s blood type was one in a million. Would he donate some of his bone marrow, they asked.
Hiroko was there in the commons, watching him. She rarely spent evenings in the village, and he didn’t need to look at her to know what she was thinking. They were made to give, she had always said, and this would be the ultimate gift. An act of pure viriditas. “Of course,” he said, happy at the opportunity.
The hospital was next to the bathhouse and the school. It was smaller than the school, and had five beds. They laid Simon on one, and Nirgal on another.
The old man smiled at him. He didn’t look sick, only old. Just like all the rest of the ancients, in fact. He had seldom said much, and now he said only, “Thanks, Nirgal.”
Nirgal nodded. Then to his surprise Simon went on: “I appreciate you doing this. The extraction will hurt afterward for a week or two, right down in the bone. That’s quite a thing to do for someone else.”
“But not if they really need it,” Nirgal said.
“Well, it’s a gift that I’ll try to repay, of course.”
Vlad and Ursula anaesthetised Nirgal’s arm with a shot. “It isn’t really necessary to do both operations now, but it’s a good idea to have you two together for it. It will help the healing if you are friends.”
So they became friends. After school Nirgal would go by the hospital, and Simon would step slowly out the door, and they would walk the path over the dunes, to the beach. There they watched the waves ripple across the white surface and rise up and crumple on the strand. Simon was a lot less talkative than anyone Nirgal had ever spent time with: it was like being silent with Hiroko’s group, only it never ended. At first it made him uncomfortable. But after a while he found it left time to really look at things: the gulls wheeling under the dome, the sandcrab bubbles in the sand, the circles surrounding each tuft of dune grass. Peter was back in Zygote a lot now, and many days he would come with them. Occasionally even Ann would interrupt her perpetual travelling, and visit Zygote and join them. Peter and Nirgal would race around playing tag, or hide and seek, while Ann and Simon strolled the beach arm in arm.
But Simon was still weak, and he got weaker. It was hard not to see this as some kind of moral failing; Nirgal had never been sick, and he found the concept disgusting. It could only happen to the old ones. And even they were supposed to have been saved by their ageing treatment, which everyone got when they were old, and so never died. Only plants and animals died. But people were animals. But they had invented the treatment. At night, worrying about these discrepancies, Nirgal read his lectern’s whole entry on leukaemia, even though it was as long as a book. Cancer of the blood. White cells proliferated out of the bone marrow and flooded the system, attacking healthy systems. They were giving Simon chemicals and irradiation and pseudoviruses to kill the white blood cells, and trying to replace the sick marrow in him with new marrow from Nirgal. They had also given him the ageing treatment three times now. Nirgal read about this too. It was a matter of genomic mismatch scanning, which found broken chromosomes and repaired them so that cell division error did not occur. But it was hard to penetrate bone with the array of introduced auto repair cells, and apparently in Simon’s case little pockets of cancerous marrow had remained behind every time. Children had a better chance of recovery than adults, as the leukaemia entry made clear. But with the ageing treatments and the marrow transfusions he was sure to get well. It was just a matter of time and of giving. The treatments cured everything in the end.
“We need a bioreactor,” Ursula said to Vlad. They were working on converting one of the ectogene tanks into one, packing it with spongy animal collagen and inoculating it with cells from Nirgal’s marrow, hoping to generate an array of lymphocytes, macrophages, and granulocytes. But they didn’t have the circulatory system working right, or perhaps it was the matrix, they weren’t sure. Nirgal remained their living bioreactor.
Sax was teaching them soil chemistry during the mornings when he was teacher, and he even took them out of the schoolroom occasionally to work in the soil labs, introducing biomass to the sand and then wheelbarrowing it to the greenhouses or the beach. It was fun work, but it tended to pass through Nirgal as if he were asleep. He would catch sight of Simon outside, stubbornly taking a walk, and he would forget whatever they were doing.
Despite the treatments Simon’s steps were slow and stiff. He walked bowlegged, in fact, his legs swinging forward with very little bend to them. Once Nirgal caught up to him and stood beside him on the last dune before the beach. Sandpipers were charging up and down the wet strand, chased by white tapestries of foaming water. Simon pointed at the herd of black sheep, cropping grass between dunes. His arm rose like a bamboo crossbar. The sheep’s frosted breath poured onto the grass.
Simon said something that Nirgal didn’t catch; his lips were stiff now, and some words he was finding hard to pronounce. Perhaps it was this that was making him quieter than ever. Now he tried again, and then again, but no matter how hard he tried Nirgal couldn’t guess what he was trying to say. Finally Simon gave up trying and shrugged, and they were left looking at each other, mute and helpless.
When Nirgal played with the other kids, they both took him in and kept their distance, so that he moved in a kind of circle. Sax admonished him mildly for his absent-mindedness in class. “Concentrate on the moment,” he would say, forcing Nirgal to recite the loops of the nitrogen cycle, or to shove his hands deep into the wet black soil they were working on, instructing him to knead it, to break up the long strings of diatom blooms, and the fungi and lichen and algae and all the invisible microbacteria they had grown, to distribute them through the rusty clods of grit. “Get it distributed as regularly as possible. Pay attention, that’s it. Nothing but this. Thisness is a very important quality. Look at the structures on the microscope screen. That clear one like a rice grain
