Crake tells Jimmy about another very important project, a Viagra-like super-pill called BlyssPluss, which also promises health and happiness, but secretly causes sterilization in order to address overpopulation. Crake officially hires Jimmy to help market it. At the Rejoov compound, Jimmy eventually sees a human in the Craker habitat and recognizes her as the girl from the pornographic video. Unaware of Jimmy's obsession with her, Crake explains that her name is Oryx and that he has hired her as a teacher for the Crakers. Oryx notices Jimmy's feelings for her and makes herself sexually available to him, despite also being Crake's romantic partner. As their relationship progresses, Jimmy becomes increasingly fearful that Crake has found out about it. He also makes a promise to both Oryx and Crake that he will look after the Crakers if anything happens to them.
