Tomalin sees Fanny as a complex personality who, despite her frailty, shows courage and grows in self-esteem during the latter part of the story. Her faith, which gives her the courage to resist what she thinks is wrong, sometimes makes her intolerant of the sinners. Fanny, always self-reflective, is intolerant of her own intolerance. Change in her character is most marked during her three months exposure to Portsmouth life. Initially, shocked by the coarseness and impropriety of her parental home and its neighbourhood, she condemns it. Her father's attitude is one that modern readers might also condemn, given the tone of incestuous sexual harassment in a man who scarcely notices her except "to make her the object of a coarse joke". While now recognising she can never be at home in Portsmouth, she gradually overcomes her acknowledged prejudices, recognises the distinctive qualities of her siblings and works hard not to cause offence. In the wider community, judgement is more even-handed; Fanny does not take to the young ladies of the town and they, offended by the 'airs' of one who neither plays on the pianoforte nor wears fine pelisses, do not take to her. She comes to see that part of her physical frailty stems from the debilitating effect of the internal arguments, conversations and identifications that sap her energy.
