In Jane Austen the Secret Radical Helena Kelly suggests that Mary is pregnant during the course of the novel. Is Mary a hypochondriac? She is the youngest child and like Anne probably didn't get much attention (even less from her mother as she was younger when she died). Have we been unjustly maligning Mary this whole time - could she have a chronic illness? Or is it about being an extrovert and really needing to feed off other people to feel "up"?

In Jane Austen The Secret Radical Helena Kelly posits that Anne and Captain Wentworth are not in love at the beginning of the book, but fall back in love during the course of the novel.

  This chapter establishes familiar character dynamics that might elucidate the trajectory of the personas Austen presents in this unfinished text. The chapter begins with the introduction of Miss Esther Denham and Sir Edward Denham, a scheming sibling pair reminiscent of Mansfield Park’s The Crawfords and Northanger Abbey’s The Thorpes. Austen explicitly establishes the bald aim of the two to obtain wealth and status from advantageous matrimony, a characteristic that similarly mirrors the Crawfords and Thorpes. Sir Edward, in particular, resembles Austen’s past villainous men; throughout the Austen canon, coxcomb-esque behaviors are the cardinal sins of bachelors. Indeed, Willoughby, Wickham, Henry Crawford, Mr. Elton, Thorpe, and Mr. Elliot all receive biting characterizations by Austen, and thus, given the fates of these men in their respective novels, we can predict that Sir Edward is not the male love interest of this story. 
 Sir Edward’s dynamic with, and apparent longing for the affection of, Clara Brereton, additionally reverberate into the Austen canon in a meaningful way. Other Austen works present relationships between gentried men and pseudo-adopted young women; notably, Emma features Jane Fairfax and Frank Churchill’s secret engagement and Mansfield Park depict Henry Crawford’s arguably predatory pursuit of Fanny Price. These relationship both demonstrate wealth and class incongruities as interpersonal complications. Further, these dynamics are also characterized by the ignorance of other characters to the details of the relationship. Therefore, we cannot know from this unfinished account of Charlotte’s observations if Clara Brereton is a Fanny Price or a Jane Fairfax; we cannot fully know if the behaviors and dispassion Charlotte Heywood witnesses are evidence of a painful resistance to unwanted advances or red herrings to disguise an intimacy. Since speculation is the nature of this activity, however, it is notable that in both Mansfield Park and Emma, outside perceptions of the aforementioned relationships were incorrect. Therefore, paradoxically, Charlotte’s perception of Clara’s distaste for Sir Edward might in fact evince a returned affection and eventual marriage between the two.
