When deciding who will stay and nurse Louisa, Wentworth suggests Anne, "no one so capable as Anne." Overhearing this gives Anne the first hope she's had in years that he might be overcoming his resentment of her.
Anne outright defying her father, and seeing her friend Mrs. Smith, who has been ailing. The older woman mentions that she can't be melancholy with Anne around.
The affection that exists between Wentworth, the Harvilles, Benwick, and the Crofts. On the visit to Lyme, Anne decides that although her family would surely disdain their less-polished manners, she would have infinitely liked better to spend the last eight years in their genuine and supportive circle than with her shallow and snobbish family.
From the adaptations:
When Anne catches sight of Admiral and Mrs. Croft in Bath, there's a big smile on her face and she immediately runs to greet them. Seeing her actually happy and in the company of people who value her is such a nice thing after an hour of watching her miserable and emotionally neglected by her father and sisters.
There's something sweet about the sight of Harville standing behind Wentworth when Wentworth interrupts the card party to propose to Anne—brother captains on all battlefields, it seems.
The look on Captain Wentworth's face when Anne joins him by the captain's wheel in the 1995 film version. Ciarán Hinds conveys volumes with one soft smile — he looks at her as though she's his entire world.
