"There's nowhere isolated enough," said Novinha. "The Descolada is infinitely variable. It attacks any kind of genetic material. The additive can be given to humans. But can they give additives to every blade of grass? To every bird? To every fish? To every bit of plankton in the sea?"
"They can all catch it?" asked Bosquinha. "I didn't know that."
"I didn't tell anybody," said Novinha. "But I built the protection into every plant that I developed. The amaranth, the potatoes, everything-- the challenge wasn't making the protein usable, the challenge was to get the organisms to produce their own Descolada blockers."
Bosquinha was appalled. "So anywhere we go--"
"We can trigger the complete destruction of the biosphere. "And you kept this a secret?" asked Dom Crist o.
"There was no need to tell it." Novinha looked at her hands in her lap. "Something in the information had caused the piggies to kill Pipo. I kept it secret so no one else would know. But now, what Ela has learned over the last few years, and what the Speaker has said tonight-- now I know what it was that Pipo learned. The Descolada doesn't just split the genetic molecules and prevent them from reforming or duplicating. It also encourages them to bond with completely foreign genetic molecules. Ela did the work on this against my will. All the native life on Lusitania thrives in plant-and-animal pairs. The cabra with the capim. The watersnakes with the grama. The suckflies with the reeds. The xingadora bird with the tropeqo vines. And the piggies with the trees of the forest."
"You're saying that one becomes the other?" Dom Crist o was at once fascinated and repelled.
"The piggies may be unique in that, in transforming from the corpse of a piggy into a tree," said Novinha. "But perhaps the cabras become fertilized from the pollen of the capim. Perhaps the flies are hatched from the tassels of the river reeds. It should be studied. I should have been studying it all these years."
"And now they'll know this?" asked Dom Crist o. "From your files?"
"Not right away. But sometime in the next twenty or thirty years. Before any other framlings get here, they'll know," said Novinha.
"I'm not a scientist," said the Bishop. "Everyone else seems to understand except me. What does this have to do with the evacuation?"
Bosquinha fidgeted with her hands. "They can't take us off Lusitania," she said. "Anywhere they took us, we'd carry the Descolada with us, and it would kill everything. There aren't enough xenobiologists in the Hundred Worlds to save even a single planet from devastation. By the time they get here, they'll know that we can't leave."
