Just as Dorothea’s admiration of Casaubon is unexpected and perhaps misplaced, the same might be said of Sir James’s attachment to Dorothea. Dorothea may be a remarkable woman, but she clearly has little interest in James. Celia evidently adores James, but he is not able to see that because he is too fixated on a woman who finds him irritating. Furthermore, James understands Dorothea so little that he mistakenly assumes it is impossible that she would be interested in Casaubon.
