Greg is a gay man married to Sue's friend Ginny. He often cheats on her with men, and sometimes tries to get her to behave more like a man herself. Father Pat "saved" their marriage through counseling. In Pray Away it is revealed that he feels incredibly guilty over putting Ginny through a sham of a marriage, and having two children with her. He begs her to divorce him, but she is clearly in denial over his true sexuality.
By the third season, Greg finally divorced Ginny and is living a happier life.
