 Bex moves in with her sister Keeley.Murray tries to re-propose to Bex, recalling they first met on a scuba diving course and visits Keeley's flat to find a positive pregnancy test which he assumes is Bex's (but is in fact Keeley's).There is resulting confusion when Murray lets the news of the pregnancy (which he hasn't verified with Bex) slip to Don and Paula (Bex and Keeley's parents) who congratulate the wrong daughter.
