Marina begins making regular morning trips to the Martins, ingesting the bark to turn herself into “medical evidence” before returning to the U.S. Other than these trips, she performs regular surgical procedures on the Lakashi, who now see her as a miracle healer, and thinks of ways to take Easter with her when she departs the station. While she plans her departure, Dr. Swenson appeals for her to stay to deliver her baby, even referring to the upcoming event as “our delivery date” (293).

Now inoculated from malaria by the Martin bark treatments, Marina is able to safely tour the doctors’ huts behind the research lab with Alan Saturn. In one of these huts, stored in buckets covered with pantyhose, are thousands of mosquitos infected with malaria. These malarial mosquitos are used periodically on Lakashi test subjects, the ethics of which practice trouble Marina. While the men are ultimately treated and cured, Marina wonders about the morality of infecting humans with malaria and only giving them coke in the exchange. Alan Saturn explains that the human trials are necessary if they plan to eradicate the disease on a global scale, saving millions of lives. “It’s the human trials that make the difference” (295), he asserts.
