Rather bizarrely, perhaps, Henry is accepting of the idea of Bon and Judith’s incestuous marriage, rationalizing what would be considered a major social taboo in his day with the notion that “kings have done it,” alluding to historical occurrences of incest. This peripherally references the biblical story that gives the novel its title, too: in that story, which is from 2 Samuel, Samuel’s son Amnon rapes his half-sister Tamar. Also of note here is the metal case that Judith sends to Bon—it’s important to remember the detail that it’s originally Judith’s photo in the case, as this will be relevant later on.
