The woman from Sealand helps David and the other telepathic children become aware of her through her incredibly strong telepathic abilities. She can communicate extremely long distances, and she begins telling David that he and his kind are not the freaks of nature that Waknuk society would have him believe.
David has been taught for his entire life that any genetic deviation outside of a strict predetermined set of norms makes someone a Deviant, and Deviant genetic coding needs to be purged from Waknuk society through banishment, sterilization, or death. David does not understand why the rule, but he does not have a big problem with the societal rule until he realizes that his telepathic ability makes him a Deviant. The woman from Sealand helps David understand that his ability is a blessing and not a curse. He is the next step in human evolution. She teaches David that change is normal, and any population that is not going through natural genetic changes is a society that is doomed to be wiped out by an up and coming "superior variant."
"For ours is a superior variant, and we are only just beginning."
She helps David see that his abilities make him a part of a population that is better able to think and adapt as a group. Her teachings are difficult for David to hear because she flatly tells him that Waknuk society and beliefs are his enemies. David already knew this, but her explanation helps him come to terms with it.
"The essential quality of life is living; the essential quality of living is change; change is evolution: and we are part of it.
"The static, the enemy of change, is the enemy of life, and therefore our implacable enemy."
