The psych doctor is one of the narrator’s colleagues in Brownlee, when the narrator works in the Verification unit of the government (Central). Since the psych doctor is assigned to deal with disaster victims all day, at night he drinks to excess, desperate to escape from the loss and pain he has just witnessed. The psych doctor is one of the few confidantes the narrator has in the novel, though he also gently mocks the narrator’s claims of “chemical” attraction to Margo.
