Xenocide (Ender Wiggins Saga)

molécula ?" 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 ," 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 é 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 ?"
    "We don't have to decide today," said Ender. "We can afford to wait awhile."
    "How do 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."
    "I think Grego just showed us why we have to wait," said Ender. "Did you hear how he talked about the descolada? It figures out how to wipe us out. Even he 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 nobody'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 screwing-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 damn 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 assuming 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
