Overview:This holiday episode is enriched by dramatic confrontations, romantic complications and poignant reconciliations. For openers, the tense situation in a previous installment involving a parish priest and an altar boy yields a startling revelation from Hanson. In other storylines, Guber and Marylin are partnered in an off-campus dance class; Ronnie and Zach are increasingly frustrated in their zealous search for a secret trysting place; and Lipschultz is predictably discomforted---especially by an invitation to attend his black son's family gathering on Christmas Day.
