It is a full house for the Hardcastles when Sandy and Harry return from Canada and move in. Jean is already imagining the pitter patter of tiny feet and, somewhat prematurely, arranges for cots to be delivered - much to the distress of Lionel. Meanwhile Sandy is convinced that Harry has a death wish when he applies to join the armed response unit in order to gain a promotion and Alistair starts to behave rather peculiarly. Just when everything is starting to settle down the doorbell rings. Jean answers it and finds a young man who has travelled all the way from Africa to see his father, Lionel!
