About EditNicholas (aka Nick) is Will's father and Eve's guardian. He was a former colleague of Mary Douglas and they worked together on Eve. He was also previously the husband of Rebecca Clarke until they got a divorce and Nick got custody of Will. When Mary Douglas disappeared and Katherine Calvin took over, Nick and Katherine were not acquainted. Katherine was, at first, suspicious of Nick and was always interrogating him for information on Mary or Project Eternity. It was in the later series that Katherine and Nick's relationship was more closer and they started to develop some feelings for each other though they hid it from each other and other people.
