Davina is thrilled when Orlando makes contact after an absence of several months. She is even more delighted that he has changed from a neurotic, pouting child into a happy, grounded adult. Not only has he become a fervent Christian, but he's in love with Cheryl; the woman who "saved" him. Impulsively, Davina invites Orlando and Cheryl to stay at the houseboat, but soon discovers that Cheryl is not exactly the angel that Orlando described. Davina turns to Sam for solace, and a little something more, which causes her vivid memories of Al to evolve dramatically. (thetvdb.com)
