I think what we are watching when we are watching Callie is a most remarkable and transparent overlay of domains. Time is nonlinear with the orbit of the child. At once, and not necessarily in chronological order, she is a mewling newborn, an eyelocker, a crawler, a cruiser, a babbler, a talker, a proto-adolescent, a power player, a mortal body, and all this time, she holds inside her the eggs that could make her a mother one day, as she has made me a mother.
She cannot change, though she is change (158-159).
