Doug and Caroline marry, and Caroline is revealed as the author of a book entitled My Sister My Love, based on the lives of the Hamiltons and the Palmers, despite the changes of character names. Doug tries to stop Caroline promoting the book, warning her that they're going to lose all their friends, but Caroline ignores him. She even writes a sequel. Caroline discovers that she's pregnant, but also learns that the baby could be born with Down's Syndrome and she opts to have an abortion, later deciding that she can't go through with it. She doesn't tell Doug that she's pregnant, but instead decides to leave him and start life afresh elsewhere. Doug learns about the pregnancy, though, and he chases after Caroline and tells her that he loves her, and that he wants her to have the baby and that he doesn't care if it's handicapped, wanting them all to be together as a family. Caroline agrees and Doug buys a fish shop in Melbourne!
