"The trouble is," said Valentine, "Quara isn't any more likely to believe our story that the descolada is an artifact created by another species than Qing-jao was able to believe that the voice of her gods was just a genetically-caused obsessive-compulsive disorder."
"I'll do it," said Planter. "I will begin immediately because we have no time. Put me in a sterile environment tomorrow, and then kill all the descolada in my body using the chemicals you've got hidden away. The ones you mean to use on humans when the descolada adapts to the current suppressant you're using."
"You realize that it may be wasted," said Ela.
"Then it would truly be a sacrifice," said Planter.
"If you start to lose your mind in a way that clearly isn't related to your body's illness," said Ela, "we'll stop the experiment because we'll have the answer."
"Maybe," said Planter.
"You might well recover at that point."
"I don't care whether I recover," said Planter.
"We'll also stop it," said Ender, "if you start to lose your mind in a way that is related to your body's illness, because then we'll know that the experiment is useless and we wouldn't learn anything from it anyway."
"Then if I'm a coward, all I have to do is pretend to be mentally failing and my life will be saved," said Planter. "No, I forbid you to stop the experiment, no matter what. And if I keep my mental functions, you must let me continue to the end, to the death, because only if I keep my mind to the end will we know that our soul is not just an artifact of the descolada. Promise me!"
"Is this science or a suicide pact?" asked Ender. "Are you so despondent over discovering the probable role of the descolada in pequenino history that you simply want to die?"
Planter rushed to Ender, climbed his body, and pressed his nose against Ender's. "You liar!" he shouted.
"I just asked a question," whispered Ender.
"I want to be free!" shouted Planter. "I want the descolada out of my body and I never want it to come back! I want to use this to help free all the piggies so that we can be pequeninos in fact and not in name!"
Gently Ender pried him back. His nose ached from the violence of Planter's pressing.
