Who is Audrey Lentz from Galatea 2.2 and what is their importance?

Audrey is Phillip Lentz's wife. Richard learns of her when he shuts the door of Lentz's office and sees a photograph of her and Phillip. Audrey has a cardiovascular accident some years back and it greatly affects her memory and her cognitive capacity. She sometimes has "good" days in which she can remember her husband or the staff at the home she lives in. On other days or even minutes after meeting him, she will become afraid of her husband and insist that he is a bad person.

She continues to have difficulty remembering how to feed herself or even that she needs to eat. Phillip and the staff often have to coach her through the meal process. It is when Richard meets Audrey that he understands some of Phillip's drive to create a machine that can be taught to think. Audrey would benefit from technology that could teach the brain to think and remember again.
