James points out that part of the reason
Mary relapsed has to do with how worried she is about
Edmund, but Edmund rejects this idea, saying that
James is the person to blame because he didn’t hire a good doctor for her when she was in pain after giving birth to him (Edmund). The doctor James hired, Edmund upholds, was cheap. When James refutes this point, Edmund switches tactics, claiming that his father has never given Mary any reason to “stay off” morphine, especially since he’s never provided her with a true home.
