Throughout the novel, Kya has been interested in the ways in which female insects lure their mates only to destroy them. Observing this phenomenon in nature taught her that there’s a certain power in sex appeal, and she never thought of this as evil or wrong because she saw it as a simple fact of nature. According to this mindset, living things must do whatever it takes to survive, even if this sometimes requires acting mercilessly. When she realized that Chase had become a threat to her wellbeing, then, she lured him into a trap, sending him falling through the hatch in the fire tower. This, she apparently thought, was only a means of survival—after all, she knew that nobody would believe her when she said that Chase posed a threat to her. Consequently, she had to address the matter herself, becoming the human version of a female firefly in a mere act of survival.
