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.
