But Lily doesn't have any other friends. Lily has a brainwave and asks Eve, who has become a daytime TV addict, to come to school with her. At Calimov, Nick is banned from the research room where Katherine is trying to piece together burnt documents and photos recovered from Mary's cabin in the woods. Nick manages to get a look and realises that very soon the pieced-together jigsaw is going to reveal Eve as a robot. Nick needs to come up with a plan quickly.
