However, "mother" is not a title explicitly used to refer to Miranda Caliban. She is not a maternal figure in the series, and her relationship with the protagonist, Christopher "Kit" Caliban, is more complex than that of a mother and son.
It's important to remember that the series deals with intricate themes of artificial intelligence, consciousness, and the nature of humanity. Miranda's role is crucial to these themes, but she's not portrayed as a traditional "mother" figure.
