When it came to Charlotte and Trey on Sex and the City, Trey MacDougal was the sort of "unicorn" that Charlotte York had been waiting her entire life to capture. Sex and the City is a show that thrives on conflict and putting its characters into impossible situations. It is no different with Charlotte and Trey. Trey is a wealthy cardiologist from old money who shared her love of familial tradition and looked good in a kilt. Unfortunately, their romantic bliss was ruptured by his issues with confrontation, over-reliance on his mother's executive function, and Charlotte's fertility woes.
