“Her face was very like that of the real Josie, but because there was at the eyes no kind smile, the upward curve of her lips gave her an expression I’d never seen before. The face looked disappointed and afraid.”

This quotation appears in the early half of Part 4, when Josie, Klara, and the Mother and Father are in Mr Capaldi’s office to work on Josie’s portrait. Here, Klara is privately discovering that the so-called portrait is actually an AF model of Josie herself, designed to stand in for Josie should the girl die. Klara’s incredible observational abilities pick up on the minor details that show that this Josie is a fake; the thing that gives it away the most is the expression on the model. Klara’s attentiveness to this detail demonstrates that Josie’s essence has not been effectively captured, and perhaps foreshadows that Mr Capaldi will not be capable of capturing it in his work. 

To show the model with a scared, sad expression gives the scene an ominous feeling, as though even the model itself senses the wrongness of its own existence. Including this expression demonstrates the fear that is clearly felt by the Mother and Father after they both view it, and indicates that even a highly sophisticated AF version of Josie is unlikely to achieve a truly convincing portrayal of the child herself, let alone “continue” her.
