Mabel has completely changed in her behavior. In the beginning of the story, she was passive, silent, sullen, and obsessed with death. Now that she believes Fergusson loves her, she is active, talkative, “triumphant,” and “animal.” Mabel’s dramatic behavioral change highlights the importance in the story of having outlets for natural, animal instincts—once Mabel has even
one potential outlet to fulfill her desires, she becomes a completely different person. At this point, Fergusson has not experienced a similar transformation: he still identifies with his socially constrained, professional role as a doctor, though his inability to resist Mabel’s advances hints at an inner conflict between his professional identity and his sexual attraction.
