Jane Austen builds this story around three sets of sisters and brothers all converging in Bath in this first half of the story. I find it interesting to note the characteristics of each set. They have their individual characteristics, of course, but some of what I have noted so far, looking at them as sets is:
*Henry and Eleanor are both intelligent, sure of who they are, are of good character, have an affectionate relationship, are respectful of each other, are people-oriented...
*Isabella and John are both self centered, talk in contradictions (inconsistent), are manipulative, controlling, and are appearance-oriented...
*Catherine and James are not as easily pigeon-holed in the same way. They apparently share an affection for each other with perhaps Catherine being the more affectionate of the two in the relationship and are both of good character but Catherine appears to rely more on valuing good principles as do Henry and Eleanor while James seems to be following in the footsteps of the Thorpe siblings to get what he wants, seeming to be willing to compromise his good character if need be.
