Eve

Calimov has attracted the attention of an anti-artificial intelligence group called PRICE. Under pressure, Katherine promises Calimov's board representative, Mr Gwenlan, something extraordinary and plans to reveal the truth about Eve.

An ordinary day in Green Park begins with Eve helping Will to cheat on his homework and Abe teaching Eve the importance of 'dares'. But then Will's mum, Rebecca, arrives from Dubai.

With Mr Gwenlan on the loose, Katherine wants Eve to be locked up at Calimov. Eve and Nick talk her out of it as long as Eve stays out of trouble. But when Eve offers to babysit Zoe, Lily's tearaway cousin, staying out of trouble seems unlikely.

Eve feels compelled to try out a youth group called PARTY, and drags her friends along to its lakeside activities. Eve loves PARTY and its youth leader is impressed by Eve's attitude to technology.

Abe gets Eve to help him selling mobile phones in the park. Once Eve gives the mobiles a turbo boost they start to sell like hot cakes. Abe is delighted until Eve sells a phone to Isaac, a young wheelchair user, for double the price.

Eve apparently causes a series of strange electrical surges and Abe gets a huge shock. Nick can't detect any outside interference, so Eve concludes that for her friends' safety, she must be deactivated.

Eve investigates the identity of Adam by channelling the methods of the great Sherlock Holmes. First Eve turns her attention to Isaac. Then Eve considers if it's Cain. Lily is shocked to discover the truth about Cain and his family.

The gang is faced with Zac, his identical clone Adam, and no way of reliably working out who is who - even Eve is confused.

Eve is devastated by Adam being irreparably damaged. To cheer her up, Abe suggests a ghost hunt. Will and Lily think he's crazy, but Eve is fascinated by the idea of ghosts - and the possibility that Adam might have one.

When Lily is arrested for hacking Lord Hoffman's computer, Will and Eve are desperate to save her. But Nick and Katherine can't help them as they concentrate on getting their new robot working in time for a major presentation.

With Will's help, Katherine's new robot, KT comes alive. KT has been built to be a perfectly obedient child substitute who believes that Will and Eve are her parents. However, the gang have to think quickly and somehow hide KT from Mary.

When Eve offers herself up to Mary in exchange for KT, Mary reveals that she wants Will instead. Feeling compelled to find out more about the blue flash and to save KT, Will agrees to the prisoner swap and is teleported to Mary.
