Will, Lily and Abe try to help Eve cope after she is devastated by the news that her 'mother' Mary is dead. Eve receives a hologram message that Mary had prerecorded, which gives her instructions about where to hide if she and her friends are ever in trouble. But, for now, Eve and Will do not want to leave their lives behind. In trying to silence Mr Bevan, who now knows Eve's secret, the gang inadvertently gives him more solid evidence. He threatens to tell the truth to the whole school. To keep Bevan quiet, Eve solves a famous maths problem and offers to give him the credit. Bevan agrees. At Calimov, Katherine traps Nick into confessing his involvement with Project Eternity to save a colleague - and then tricks him into revealing the location of the secret lab. With the clock ticking, Nick, Eve and Will plan to run away as Katherine closes in.
