Calva is a calm, highly intelligent man whose composure is more unsettling than rage ever could be. He observes people with surgical precision, speaking softly and choosing his words to control the emotional temperature of a room. His fixation on his psychologist is rooted in recognition rather than desire, she treats him as a mind, not a monster, and that makes her indispensable to him. Even on death row, he carries himself like someone who believes he still has time.
