Partials

That could explain why the babies don’t get sick until after they’re born.

Kira paused, caught by a sudden thought. If the virus is big enough to be contained, why can’t we deliver infants in a contained environment? They scrubbed the room, they sterilized their tools, they wore gas masks — they did everything they could think of, yet the virus still got through.

I’m not the first person to ask that question, she thought. Marcus and Dr. Skousen both said that people have been researching this since the Break. That means there’ll be records somewhere of their findings. She called up the database files in the microscope, searching for studies of all their clean-room births, and found several. None had been successful, obviously; the rate of sickness and the onset of RM was virtually identical to that of normal births, as if the clean room had shown no effect at all. Attached to the records was another set of studies, this time focusing on the existence of an RM variant found only in the air. Kira opened this with interest — she knew that RM was airborne, of course, but the actual structure of the airborne virus was not exactly entry-level medicine, and they hadn’t talked about it yet in any of her classes. The report contained more images, similar to those in her blood sample but much smaller: between twenty-three and thirty- one nanometers. Kira frowned. Something that small would be almost impossible to catch, even with a clean room. She looked at the Partial, feeling a surge of her old anger.

“You made pretty damn sure we couldn’t get away from this thing, didn’t you?”

The Partial turned its head to look at her, and Kira felt like she could almost see the thoughts whirring through its mind. When it spoke, its eyes seemed almost … curious. “You can’t reproduce.”

“What?”

“That’s why you’re trying to cure RM. We don’t have children, so their absence didn’t seem odd at first, but you don’t have any, do you? You’re trying to cure RM because your children don’t survive it.”

Kira wanted to scream at it, to force it to acknowledge its own hand in their extinction, to attack it for daring to speak so matter-of-factly about something so terrible, and yet she stopped, one thought catching in her mind.

Did it not know the virus was still killing them? She knew she shouldn’t trust it, but it seemed like something it was just now understanding. It really hadn’t known. But if it hadn’t known, that suggested two very important things: first, that the Partials weren’t spying on them. The theories cropped up now and then, that Partials were hiding among them, infiltrating the island with deep cover spies. But if that were true, this one would already have known that human infants were dying. Its surprise meant they weren’t being watched.

Or if they are watching, she thought, they aren’t telling each other what they see.

The second thing it suggested was that the Partials — or at least this Partial in particular — did not know how RM worked. It hadn’t expected the virus to stick around, and presumably most of the Partials it interacted with thought the same. Were the Partial leaders hiding the information from their own soldiers, or did they not know either? And how could they not know the function of a virus they’d created? It was possible the virus had mutated; Kira shuddered at the thought of it. If something as deadly as RM was mutating, acting beyond its original parameters, who knew what it was capable of?

She supposed there was one way to find out how much he knew. “You,” she said, “Partial. What do you know about RM?”

It didn’t answer.

“Oh, come on,” said Kira, rolling her head back in frustration. “Are we going to go through this again? Can’t you at least say something?”

“Well, human,” he said, “you’re going to kill me in five days. I don’t see much of an incentive to say anything.”

Kira stormed back to the medicomp and threw herself into the chair, so angry she could hardly think. It was going to be killed because it had killed Gabe, and Skinny, and six billion other people. After everything it had done, every atrocity it had been a part of, how dare it have the temerity to imply that it was a victim?

The images on the screen seemed to swirl and blur; how could she concentrate with that thing lying twenty feet away? It was times like this when she needed Marcus to make a joke, to defuse the situation and help her realize what mattered and what didn’t. She looked at the door, but of course he wasn’t there. He didn’t even know where she was.

The Partial was right about one thing: She only had five days. She needed to work. She pushed the Partials out of her mind and forced herself to focus on the task at hand: a screen full of viral images, a series of reports on the viral structure. It had two forms, one for blood and one for air; the Blob and the Spore, the yellow and the blue. Concentrate! The Spore was tiny, perfect for traveling through the air. That must be how the virus passed from host to host. But then what was the Blob for?

None of the studies had the answer; they knew both forms of the virus existed, but not how they worked together. Kira turned back to the sample report from Marcus’s blood, combing through the results for any sign of the Spore. If it could get into the body, it would; there should be some sign of it in Marcus’s sample, but there was nothing. That meant that whatever happened to the Spore when it got into the body was happening very quickly, and leaving no trace.

That is, the Blob was the trace. Kira ran through the possibilities in her head: The virus obviously reacted to human blood and tissue — that was how it worked, using the host body’s own material to replicate itself — so maybe there was an extra layer of interaction. Maybe the Spore wasn’t designed to replicate itself at all, just to convert itself into the Blob and let that one replicate. It was weird, but it was possible. Whatever it does, thought Kira, it has to do it quickly: By the time we get a chance to test the blood, any samples of the Spore have all been converted. Kira ran her fingers through her hair, trying to figure out how to see the transformation in action. If she could get a sample of uninfected blood, and get it into the medicomp fast enough, she’d be able to study the actual process of infection. But where could she find uninfected human blood?

In the newborns. There were four pregnant women in the city due to deliver in the next week, and several samples beyond that if one of the other mothers delivered early.

She would put a request in to Dr. Skousen, just to see what he said. They always took blood samples at birth, but they usually didn’t test those samples for several minutes while they dealt with other problems — most blood samples aren’t this time-sensitive. If Kira’s theory was correct, they’d have to test the blood immediately if they wanted to see this specific reaction.

The next question was the more difficult one: If the Blob came from transformed Spores, where did the Spores come from? Did the Blob create them, or did it transform back? Observing that change would be difficult, because she had no idea how it worked, and thus how to re-create it. Obviously the transformation couldn’t happen in the blood, because it would reverse itself instantly. The lack of any Spore samples in Marcus’s blood attested to that. In the lungs, then? Does the Blob react to oxygen the same way the Spore reacts to tissue? It was the simplest answer, which made it the best place to start. But how could she test it?

I need to isolate the virus first, she thought. She looked around the room for something that could trap the tiny virus, and her eyes fell on a box of latex gloves. She remembered how she and Marcus used to inflate them in school, pinching them almost closed and blowing them full of air. If the virus transformation really did happen in the lungs, her breath would be full of it. And if a rubber glove will hold oxygen, it’ll contain the virus too, at least long enough to take a look at in the medicomp. She walked to the rubber gloves, held one to her mouth, and blew it up like a balloon. Now what? She stood in the middle of the room uncertainly. Would the medicomp be able to read anything through the rubber? Probably, even if she felt stupid shoving an inflated rubber glove into the sensor bay. But there was another problem, which was that whatever she did with her own breath, she’d have to do the same with the Partial’s breath as well. Both tests needed to be the same, or the results wouldn’t mean anything, and she was pretty sure the Partial wouldn’t blow up a rubber glove. She let the glove deflate. She’d have to think of something else.

“We were winning the war,” said the Partial softly. Kira still started when it spoke, not expecting to hear anything from it.

“What?” Kira stared at it, then shoved the glove into her pocket. “Why the hell are you bringing that up?”

“Because you think we created the virus; that’s why you’re studying me as part of your mission to cure it.
