Although the procedure to modify Joseph’s genes is in some ways a scientific or medical one, this passage suggests that it is also a sexual one. This passage suggests that sex need not always be about physical but is also about mental connections, as embodied in this passage by the neural link connecting Nikanj, Lilith, and Joseph. Lilith’s fears of pregnancy—how the Oankali might take advantage of her ability to be a mother—show how even though she engages in this sexual activity with Nikanj, she still isn’t sure whom she can trust.
