First Abe’s tablet goes haywire – and then, apparently, so does Eve, who seems to have forgotten that she is a robot and that she ever knew a guy called Zac. But when Eve sees Lily’s parents, Maddy and Simon together, she begins to remember fragmentary flashes of Zac. Determined to fill in the blanks, Eve asks Maddy to drive her to Calimov, where Zac worked, so she can understand who he was and why he is no longer in her life. Will and Lily work out that Eve used Abe’s clean-up software to delete her own memory?
