A quarter of a century later,Mark is due to marry girlfriend Jo. Betty,who has given Mark the love she once reserved for Craze, is doubly shocked as not only are the young couple moving to Australia but she suspects that Jo, who is adopted, may be Moira and Craze's daughter. Jo introduces her to Ingrid,who is her real birth mother, through whom she re-encounters Moira - on the day of Mark's wedding. Moira delivers some home truths about Craze's dishonesty and adultery which Betty refuses to accept, climbing up onto the roof of her house until Moira has gone. A crowd gathers but she is eventually rescued by Donald,who tells her he knew all about Craze and tolerated it because it made Betty happy,which is all he ever wanted because,although he was not one for romantic gestures, he truly loved her. Betty comes to appreciate the difference between passion and love and, after the wedding, goes for a romantic air-balloon trip with Donald.
