Peter Burke says that he interviewed Cabot Hawkins, aka Agent 723, in a psych ward. Burke discounts what 723 told him after 723 mentioned he had been infected by a parasite that subtly changed his personality. That parasite does in fact exist. It is called Toxoplasma gondii and it has been shown that mice infected by it become bolder, losing their inherent fear of cats. Cats are the natural hosts of Toxoplasma, which is excreted in their feces. Rodents who then ingest the parasite are more likely to be preyed upon by other cats, thereby completing the parasite's life cycle. Humans infected with Toxoplasma have been shown to become more extroverted and less conscientious, a personality change that increases the longer the parasite remains untreated.
