text: Creators and writers Brian Cooke and Johnnie Mortimer had to gain special permission from the Independent Broadcasting Authority (IBA), then the regulatory body for commercial television in Britain, to be able to portray an unmarried couple living together; special concern arose at scenes in which Robin and Vicky were seen in an obvious state of undress in bed. In 1978, Robin and Vicky married and two years later had a set of twins, whom they eventually name Lucy and James Alexander Tripp. At the end of the last episode, Vicky tells Robin that she's pregnant again.
