Trey MacDougal is an attractive WASP, a charming gentleman with a pedigree as fine as Charlotte's. Trey is a cardiologist. He is noted to be an ideal catch even by her extremely picky standards. She marries him, but soon learns that they have no compatibility in the bedroom. His inability to be successfully intimate with Charlotte creates a wedge between them and an unfulfilled desire in her. At one point Charlotte makes out with a desirable gardener. Trey is upset yet instead finds himself attempting to work on his tennis serve to distract himself. She then suggests separation. Charlotte later divorces Trey.
His family heritage is from Scotland and they are even wealthier than the Yorks. The undisputed head of the family is Trey's mother Bunny, who rules with an iron fist in a velvet glove. Bunny smothers Trey's manhood. He seems quite content to remain for life her tenderly beloved boy, she even used to sit by his bath and personally nurse him when sick.
