Denis: Entomologist, 30-year old assistant professor at a large university (in 1985); married 47-year old father and department chair (in 2002). He suffers from a sense of detached isolation, even in his closest personal relationships.
Denny (Denis as an adolescent): 13-year old boy (in 1968). A shy introvert, drawn to science and provable facts. He lives with his father. His mother, who was absent for much of his childhood, died when he was eleven years old. He is impatient to outgrow what he sees as the immaturity of childhood, to become a man.
