Nigel is one of Daphne's innumerable brothers, who attends her wedding to Donny Douglas. As with most of her brothers, Daphne makes occasional references to Nigel. It is implied he became a fisherman and a womanizer along with his other brothers. It is once mentioned that his brother Billy would peek at him in the shower, suggesting he is perhaps better looking/built than the other Moon men.
At one point Daphne tells a (possibly fabricated) story about how Nigel became obsessed with cash after receiving a coin form the tooth fairy and began punching people’s mouths to collect their teeth. He was said to have been expelled, became a thief, and was arrested.
