In “Silver Bells,” James had been married to Mindy but fell in love with Patti, whom he met at work. He didn’t want to leave Mindy, and especially did not want to disrupt the marriage for their children, so instead he brought Patti home to live with them. James fertilized Patti’s egg and Mindy carried the child, so their youngest child is by all three of them. Mindy stays at home and mothers their children, while Patti and James both work at the same law firm. The three are seeking legal recognition for their union.
