Abby's life now seems a million miles away from London, but just as she is beginning to feel accepted as by the island community on Ronansay, Robbie, the children's father, turns up. He was a lousy boyfriend and father, and is not welcome. Kenny, meanwhile, has finally accepted that his feelings for Abby will remain unrequited and decides to move on emotionally. Another erring father is Alistair, who is struggling with the reality of Carolyn's baby girl and distances himself from them. And there's another new face on the island: Malcolm's cousin Colin, who unwittingly causes sparks by always saying the wrong thing.
