“We might be able to harvest it,” said Ether. “We could keep them in a controlled environment—a prison camp, or a smaller island where we can watch them more closely—and then send a few people in every morning to collect the healing particles. Then we could distribute it through the army like an inoculation.”

Delarosa’s face was livid.

Now they’re re-creating my own failed plans, thought Vale. “Suppose that doesn’t work,” he said. “Suppose it takes”—he reversed the numbers from the Preserve—“ten humans for every two thousand Partials. One human for two hundred. If we implement this now, today, before losing any more soldiers to expiration, we’d need what, one thousand of them? Fifteen hundred? How do you support that many humans?”

“They could support themselves,” said Audra. “We’d make it a . . . like a labor camp.”

“And the Partials that live with them?” asked Vale. “As I said, they need to be in close proximity to Partials in order to produce the particle. Would those Partials live in the labor camp too?”

“They’d need guards anyway,” said Audra. “We could take shifts.”

“And what about the other thirty thousand humans?” asked Vale, feeling increasingly repelled by the entire conversation. “What do we do with the ones we don’t need? Do we put them in labor camps as well, or just kill them outright?”

“Fifteen hundred is already large for a sustainable prison population,” said Ether. “If we want to keep them from attacking us, or escaping and making the whole thing moot, we have to limit the population as much as we—”

“Listen to yourselves!” shouted Vale. His felt his heart pounding, his blood pressure rising even with a host of gene mods to keep it in check. “They’re not animals! They created you!”

“And they tried to destroy us,” said Audra. “This prison camp idea isn’t all that different from what we’ve done all along, keeping them isolated to Long Island. But keeping them alive was a mistake. Do you know what else we’ve seen on the satellite? They’re massing in the south—a giant human army, armed to the teeth, gathering for a final push.”

“Gathering in the south?” asked Vale. “As far away from us as possible?”

“They’re getting out of the blast radius,” said Audra. “What else could it be? They retreat to the South Shore, send her to trigger the bomb, and then come around Manhattan and up the river to clean up any survivors.”

“That’s a military plan,” said Vale. “They’re not an army! That’s what you’d do, but not—” But even as he said it, he realized he was caught in a loop of flawed logic generated by racist suspicion, one he could never hope to talk his way out of. “Just . . . get out, all of you.”
