Ronny Heaslop is pictured as the "rubber-stamp" product of the Public School crowd for whom Forster had so much contempt. He is the typical follower, influenced by power, prestige, and a set pattern of behavior. These traits make it easy for him to be led into the Turton-Callendar-McBryde camp, for they represent to Ronny the peak of social and political prestige.
As a disciple of the Public School tradition, Ronny is the epitome of the class-conscious Englishman. He does not judge on the basis of merit, but rather by position on the social ladder. As a result of his training, he cannot countenance, or understand, anyone who questions these standards. This is why Adela is unsuitable for him and why he cannot be reached by his mother's arguments.
Ronny is the issue of Mrs. Moore's first marriage. It is possible that, when he was young, she had not reached the level of maturity and perception that would have influenced his life as it seems to have affected the lives of her younger children.
