Perhaps the most fascinating relationship in this novel is the relationship introduced in this section between Clifford Chatterley, the crippled aristocrat, and Mrs. Bolton, the working-class nurse who becomes his sole companion and caretaker. It is probably Lawrence's most honest grappling with the question of inter-class relationships. Mrs. Bolton is no classless abstraction, like Mellors; rather, she is deeply rooted in the working class, and it is a complex tangle of emotions that connects her to Clifford. He depends upon her, but disdains her; she serves him, but also controls him, for he is powerless on his own. And she has an awe of aristocrats, while despising them for their treatment of the working class. As the novel progresses, their relationship assumes something of the quality of a romantic love affair, even as it remains a master-servant relationship; a companionship between friends; and a mother-child relationship, with Clifford completely dependent on Mrs. Bolton.
