Xenocide Part 10

"They throw darts darts," said Grego.

"That was my own word for it," said Quara. "I didn't understand that it was speech speech."

"Because it wasn't speech," said Grego.

"That was five years ago," said Ender. "You said the darts they send out carry the needed genes and then all the viruses that receive the darts revise their own structure to include the new gene. That's hardly language."

"But that isn't the only only time they send darts," said Quara. "Those messenger molecules are moving in and out all the time, and most of the time they aren't incorporated into the body at all. They get read by several parts of the descolada and then they're pa.s.sed on to another one." time they send darts," said Quara. "Those messenger molecules are moving in and out all the time, and most of the time they aren't incorporated into the body at all. They get read by several parts of the descolada and then they're pa.s.sed on to another one."

"This is language?" asked Grego.

"Not yet," said Quara. "But sometimes after a virus reads one of these darts, it makes a new dart and sends it out. Here's the part that tells me it's a language: The front part of the new dart always begins with a molecular sequence similar to the back tag of the dart that it's answering. It holds the thread of the conversation together."

"Conversation," said Grego scornfully.

"Be quiet or die," said Ela. Even after all these years, Ender realized, Ela's voice still had the power to curb Grego's snottiness-- sometimes, at least.

"I've tracked some of these conversations for as many as a hundred statements and answers. Most of them die out much sooner than that. A few of them are incorporated into the main body of the virus. But here's the most interesting thing-- it's completely voluntary. Sometimes one virus will pick up that dart and keep it, while most of the others don't. Sometimes most of the viruses will keep a particular dart. But the area where they incorporate these message darts is exactly that area that has been hardest to map. It's hardest to map because it isn't part of their structure, it's their memory memory, and individuals are all different from each other. They also tend to weed out a few memory fragments when they've taken on too many darts."

"This is all fascinating," said Grego, "but it isn't science. There are plenty of explanations for these darts and the random bonding and shedding--"

"Not random!" said Quara. random!" said Quara.

"None of this is language," said Grego.

Ender ignored the argument, because Jane was whispering in his ear through the jewel-like transceiver he wore there. She spoke to him more rarely now than in years past. He listened carefully, taking nothing for granted. "She's on to something," Jane said. "I've looked at her research and there's something going on here that doesn't happen with any other subcellular creature. I've run many different a.n.a.lyses on the data, and the more I simulate and test this particular behavior of the descolada, the less it looks like genetic coding and the more it looks like language. At the moment we can't rule out the possibility that it is is voluntary." voluntary."

When Ender turned his attention back to the argument, Grego was speaking. "Why do we have to turn everything we haven't figured out yet into some kind of mystical experience?" Grego closed his eyes and intoned, "I have found new life! I have found new life!"

"Stop it!" shouted Quara.

"This is getting out of hand," said Novinha. "Grego, try to keep this at the level of rational discussion."

"It's hard to, when the whole thing is so irrational. Ate agora quem ja imaginou microbiologista que se torna namorada de uma molecula Ate agora quem ja imaginou microbiologista que se torna namorada de uma molecula?" Who ever heard of a microbiologist getting a crush on a molecule?

"Enough!" said Novinha sharply. "Quara is as much a scientist as you are, and--"

"She was was," muttered Grego.

"And-- if you'll kindly shut up long enough to hear me out-- she has a right to be heard." Novinha was quite angry now, but, as usual, Grego seemed unimpressed. "You should know by now, Grego, that it's often the ideas that sound most absurd and counterintuitive at first that later cause fundamental shifts in the way we see the world."

"Do you really think this is one of those basic discoveries?" asked Grego, looking them in the eye, each in turn. "A talking virus? Se Quara sabe tanto, porque ela nao diz o que e que aqueles bichos dizem? Se Quara sabe tanto, porque ela nao diz o que e que aqueles bichos dizem?" If she knows so much about it, why doesn't she tell us what these little beasts are saying? It was a sign that the discussion was getting out of hand, that he broke into Portuguese instead of speaking in Stark, the language of science-- and diplomacy.

"Does it matter?" asked Ender.

"Matter!" said Quara.

Ela looked at Ender with consternation. "It's only the difference between curing a dangerous disease and destroying an entire sentient species. I think it matters."

"I meant," said Ender patiently, "does it matter whether we know what they're saying."

"No," said Quara. "We'll probably never understand their language, but that doesn't change the fact that they're sentient. What do viruses and human beings have to say to each other, anyway?"

"How about, 'Please stop trying to kill us'?" said Grego. "If you can figure out how to say that in virus language, then this might be useful."

"But Grego," said Quara, with mock sweetness, "do we say that to them, or do they say that to us us?"

"We don't have to decide today," said Ender. "We can afford to wait awhile."

"How do you you know?" said Grego. "How do you know that tomorrow afternoon we won't all wake up itching and hurting and puking and burning up with fever and finally dying because overnight the descolada virus figured out how to wipe us out once and for all? It's us or them." know?" said Grego. "How do you know that tomorrow afternoon we won't all wake up itching and hurting and puking and burning up with fever and finally dying because overnight the descolada virus figured out how to wipe us out once and for all? It's us or them."

"I think Grego just showed us why we have have to wait," said Ender. "Did you hear how he talked about the descolada? It to wait," said Ender. "Did you hear how he talked about the descolada? It figures out figures out how to wipe us out. Even how to wipe us out. Even he he thinks the descolada has a will and makes decisions." thinks the descolada has a will and makes decisions."

"That's just a figure of speech," said Grego.

"We've all been talking that way," said Ender. "And thinking that way, too. Because we all feel it-- that we're at war with the descolada. That it's more than just fighting off a disease-- it's like we have an intelligent, resourceful enemy who keeps countering all our moves. In all the history of medical research, no one has ever fought a disease that had so many ways to defeat the strategies used against it."

"Only because n.o.body's been fighting a germ with such an oversized and complex genetic molecule," said Grego.

"Exactly," said Ender. "This is a one-of-a-kind virus, and so it may have abilities we've never imagined in any species less structurally complex than a vertebrate."

For a moment Ender's words hung in the air, answered by silence; for a moment, Ender imagined that he might have served a useful function in this meeting after all, that as a mere talker he might have won some kind of agreement.

Grego soon disabused him of this idea. "Even if Quara's right, even if she's dead on and the descolada viruses all have doctorates of philosophy and keep publishing dissertations on s.c.r.e.w.i.n.g-up-humans-till-they're-dead, what then? Do we all roll over and play dead because the virus that's trying to kill us all is so d.a.m.n smart?"

Novinha answered calmly. "I think Quara needs to continue with her research-- and we need to give her more resources to do it-- while Ela continues with hers."

It was Quara who objected this time. "Why should I bother trying to understand them if the rest of you are still working on ways to kill them?"

"That's a good question, Quara," said Novinha. "On the other hand, why should you bother trying to understand them if they suddenly figure out a way to get past all our chemical barriers and kill us all?"

"Us or them," muttered Grego.

Novinha had made a good decision, Ender knew-- keep both lines of research open, and decide later when they knew more. In the meantime, Quara and Grego were both missing the point, both a.s.suming that everything hinged on whether or not the descolada was sentient. "Even if they're sentient," said Ender, "that doesn't mean they're sacrosanct. It all depends whether they're raman or varelse. If they're raman-- if we can understand them and they can understand us well enough to work out a way of living together-- then fine. We'll be safe, they'll be safe."

"The great peacemaker plans to sign a treaty with a molecule?" asked Grego.

Ender ignored his mocking tone. "On the other hand, if they're trying to destroy us, and we can't find a way to communicate with them, then they're varelse-- sentient aliens, but implacably hostile and dangerous. Varelse are aliens we can't live with. Varelse are aliens with whom we are naturally and permanently engaged in a war to the death, and at that time our only moral choice is to do all that's necessary to win."

"Right," said Grego.

Despite her brother's triumphant tone, Quara had listened to Ender's words, weighed them, and now gave a tentative nod. "As long as we don't start from the a.s.sumption that they're varelse," said Quara.

"And even then, maybe there's a middle way," said Ender. "Maybe Ela can find a way to replace all the descolada viruses without destroying this memory-and-language thing."

"No!" said Quara, once again fervent. "You can't-- you don't even have the right right to leave them their memories and take away their ability to adapt. That would be like to leave them their memories and take away their ability to adapt. That would be like them them giving all of giving all of us us frontal lobotomies. If it's war, then it's war. Kill them, but don't leave them their memories while stealing their will." frontal lobotomies. If it's war, then it's war. Kill them, but don't leave them their memories while stealing their will."

"It doesn't matter," said Ela. "It can't be done. As it is, I think I've set myself an impossible task. Operating on the descolada isn't easy. Not like examining and operating on an animal. How do I anesthetize the molecule so that it doesn't heal itself while I'm halfway through the amputation? Maybe the descolada isn't much on physics, but it's a h.e.l.l of a lot better than I am at molecular surgery."

"So far," said Ender.

"So far we don't know anything," said Grego. "Except that the descolada is trying as hard as it can to kill us all, while we're still trying to figure out whether we ought to fight back. I'll sit tight for a while longer, but not forever. "

"What about the piggies?" asked Quara. "Don't they they have a right to vote on whether we transform the molecule that not only allows them to reproduce, but probably created them as a sentient species in the first place?" have a right to vote on whether we transform the molecule that not only allows them to reproduce, but probably created them as a sentient species in the first place?"

"This thing is trying to kill us," said Ender. "As long as the solution Ela comes up with can wipe out the virus without interfering with the reproductive cycle of the piggies, then I don't think they have any right to object."

"Maybe they'd feel different about that."

"Then maybe they'd better not find out what we're doing," said Grego.

"We don't tell people-- human or pequenino-- about the research we're doing here," said Novinha sharply. "It could cause terrible misunderstandings that could lead to violence and death."

"So we humans are the judges of all other creatures," said Quara.

"No, Quara. We scientists scientists are gathering information," said Novinha. are gathering information," said Novinha.

"Until we've gathered enough, n.o.body n.o.body can judge anything. So the secrecy rule goes for everybody here. Quara and Grego both. You tell no one until I say so, and I won't say so until we know more." can judge anything. So the secrecy rule goes for everybody here. Quara and Grego both. You tell no one until I say so, and I won't say so until we know more."

"Until you you say so," asked Grego impudently, "or until the Speaker for the Dead says so?" say so," asked Grego impudently, "or until the Speaker for the Dead says so?"

"I'm the head xen.o.biologist," said Novinha. "The decision on when we know enough is mine alone. Is that understood?"

She waited for everyone there to a.s.sent. They all did.

Novinha stood up. The meeting was over. Quara and Grego left almost immediately; Novinha gave Ender a kiss on the cheek and then ushered him and Ela out of her office.

Ender lingered in the lab to talk to Ela. "Is there a way to spread your replacement virus throughout the entire population of every native species on Lusitania?" there a way to spread your replacement virus throughout the entire population of every native species on Lusitania?"

"I don't know," said Ela. "That's less of a problem than how to get it to every cell of an individual organism fast enough that the descolada can't adapt or escape. I'll have to create some kind of carrier virus, and I'll probably have to model it partly on the descolada itself-- the descolada is the only parasite I've seen that invades a host as quickly and thoroughly as I need the carrier virus to do it. Ironic-- I'll learn how to replace the descolada by stealing techniques from the virus itself."

"It's not ironic," said Ender, "it's the way the world works. Someone once told me that the only teacher who's worth anything to you is your enemy."

"Then Quara and Grego must be giving each other advanced degrees," said Ela.

"Their argument is healthy," said Ender. "It forces us to weigh every aspect of what we're doing."

"It'll stop being healthy if one of them decides to bring it up outside the family," said Ela.

"This family doesn't tell its business to strangers," said Ender. "I of all people should know that." family doesn't tell its business to strangers," said Ender. "I of all people should know that."

"On the contrary, Ender. You of all people should know how eager we are to talk to a stranger-- when we think our need is great enough to justify it."

Ender had to admit that she was right. Getting Quara and Grego, Miro and Quim and Olhado to trust him enough to speak to him, that had been hard when Ender first came to Lusitania. But Ela had spoken to him from the start, and so had all of Novinha's other children. So, in the end, had Novinha herself. The family was intensely loyal, but they were also strong-willed and opinionated and there wasn't a one of them who didn't trust his own judgment above anyone else's. Grego or Quara, either one of them, might well decide that telling somebody else was in the best interests of Lusitania or humanity or science, and there would go the rule of secrecy.

Just the way the rule of noninterference with the piggies had been broken before Ender ever got here.

How nice, thought Ender. One more possible source of disaster that is completely out of my power to control.

Leaving the lab, Ender wished, as he had many times before, that Valentine were here. She was the one who was good at sorting out ethical dilemmas. She'd be here soon-- but soon enough? Ender understood and mostly agreed with the viewpoints put forward by Quara and Grego both. What stung most was the need for such secrecy that Ender couldn't even speak to the pequeninos, not even Human himself, about a decision that would affect them as much as it would affect any colonist from Earth. And yet Novinha was right. To bring the matter out into the open now, before they even knew what was possible-- that would lead to confusion at best, anarchy and bloodshed at worst. The pequeninos were peaceful now-- but the species' history was b.l.o.o.d.y with war.

As Ender emerged from the gate, heading back toward the experimental fields, he saw Quara standing beside the fathertree Human, sticks in her hand, engaged in conversation. She hadn't actually beat on his trunk, or Ender would have heard it. So she must want privacy. That was all right. Ender would take a longer way around, so he wouldn't come close enough to overhear.

But when she saw Ender looking her way, Quara immediately ended her conversation with Human and took off at a brisk walk down the path toward the gate Of course this led her right by Ender.

"Telling secrets?" asked Ender. He had meant his remark as mere banter. Only when the words came out of his mouth and Quara got such a furtive look on her face did Ender realize exactly what secret it might have been that Quara had been telling. And her words confirmed his suspicion.

"Mother's idea of fairness isn't always mine," said Quara. "Neither is yours, for that matter."

He had known she might might do this, but it never occurred to him she would do it so quickly after promising not to. "But is fairness always the most important consideration?" asked Ender. do this, but it never occurred to him she would do it so quickly after promising not to. "But is fairness always the most important consideration?" asked Ender.

"It is to me," said Quara.

She tried to turn away and go on through the gate, but Ender caught her arm.

"Let go of me."

"Telling Human is one thing," said Ender. "He's very wise. But don't tell anybody else. Some of the pequeninos, some of the males, they can be pretty aggressive if they think they have reason."

"They're not just males males," said Quara. "They call themselves husbands. Maybe we we should call them should call them men men." She smiled at Ender in triumph. "You're not half so open-minded as you like to think." Then she brushed past him and went on through the gate into Milagre.

Ender walked up to Human and stood before him. "What did she tell you, Human? Did she tell you that I'll die before I let anyone wipe out the descolada, if doing so would hurt you and your people?"

Of course Human had no immediate answer for him, for Ender had no intention of starting to beat on his trunk with the talking sticks used to produce Father Tongue; if he did, the pequenino males would hear and come running. There was no private speech between pequeninos and fathertrees. If a fathertree wanted privacy, he could always talk silently with the other fathertrees-- they spoke to each other mind to mind, the way the Hive Queen spoke to the b.u.g.g.e.rs that served as her eyes and ears and hands and feet. If only I were part of that that communications network, thought Ender. Instantaneous speech consisting of pure thought, projected anywhere in the universe. communications network, thought Ender. Instantaneous speech consisting of pure thought, projected anywhere in the universe.

Still, he had to say something to help counteract the sort of thing he knew Quara would have said. "Human, we're doing all we can to save human beings and pequeninos, both. We'll even try to save the descolada virus, if we can. Ela and Novinha are very good at what they do. So are Grego and Quara, for that matter. But for now, please trust us and say nothing to anyone else. Please. If humans and pequeninos come to understand the danger we're in before we're ready to take steps to contain it, the results would be violent and terrible."

There was nothing else to say. Ender went back to the experimental fields. Before nightfall, he and Planter completed the measurements, then burned and flashed the entire field. No large molecules survived inside the disruption barrier. They had done all they could to ensure that whatever the descolada might have learned from this field was forgotten.

What they could never do was get rid of the viruses they carried within their own cells, human and pequenino alike. What if Quara was right? What if the descolada inside the barrier, before it died, managed to "tell" the viruses that Planter and Ender carried inside them about what had been learned from this new strain of potato? About the defenses that Ela and Novinha had tried to build into it? About the ways this virus had found to defeat their tactics?

If the descolada were truly intelligent, with a language to spread information and pa.s.s behaviors from one individual to many others, then how could Ender-- how could any of them-- hope to be victorious in the end? In the long run, it might well be that the descolada was the most adaptable species, the one most capable of subduing worlds and eliminating rivals, stronger than humans or piggies or b.u.g.g.e.rs or any other living creatures on any settled worlds. That was the thought that Ender took to bed with him that night, the thought that preoccupied him even as he made love with Novinha, so that she felt the need to comfort him as if he, not she, were the one burdened with the cares of a world. He tried to apologize but soon realized the futility of it. Why add to her worries by telling of his own?

Human listened to Ender's words, but he couldn't agree with what Ender asked of him. Silence? Not when the humans were creating new viruses that might well transform the life cycle of the pequeninos. Oh, Human wouldn't tell the immature males and females. But he could-- and would-- tell all the other fathertrees throughout Lusitania. They had a right to know what was going on, and then decide together what, if anything, to do.

Before nightfall, every fathertree in every wood knew all that Human knew: of the human plans, and of his estimation of how much they could be trusted. Most agreed with him-- we'll let the human beings proceed for now. But in the meantime we'll watch carefully, and prepare for a time that might come, even though we hope it won't, when humans and pequeninos go to war against each other. We cannot fight and hope to win-- but maybe, before they slaughter us, we can find a way for some of us to flee.

So, before dawn, they had made plans and arrangements with the Hive Queen, the only nonhuman source of high technology on Lusitania. By the next nightfall, the work of building a starship to leave Lusitania had already begun.
