Fan Casting sophie in runaway circuits

Sophie is a service android from the year 2040. However, as she was one of the last models released to the public after the plague had already emerged, she was never sold or activated until now. She is slightly more advanced than Curtis, to the point that her robotic nature is almost imperceptible. In simple terms, like Curtis, it's very difficult to tell if she's android or human. She was purchased by Harland as a potential new assistant because Harland knows Curtis doesn't have much time left, and it is thanks to her that he is able to develop a possible cure for the plague. However, when Harland's employers pursue him for the cure, Sophie dedicates herself to protecting the doctor and ensuring the cure doesn't fall into the wrong hands. Throughout the story, Sophie will learn a little about this world and how it might affect someone like her.
