Tom Bertram's means to escape his mother and his aunt.
Edmund and Mary discuss the respective merits of becoming a minister (living a safe, reassuring life, following one's vocation, helping others) and choosing any other respectable profession (being fashionable, being richer, being able to marry Mary Crawford). They neglect Fanny, who is stuck between them like meal inside a bad sandwich. Accidentally, in the middle of their romantic hints, she ruins the moment by lapsing into panygiric about the chaplain who took care well of her brother, ruining the mood by reminding them of her presence near them.
Mrs Norris bewilderment at the idea that Fanny is asked to go see Sir Thomas Bertram. Baddeley the servant in this scene is even more hilarious because he knows that Sir Thomas actually sent for Fanny to see Henry Crawford so that he could talk to her in private.
But Baddeley was stout. “No, ma’am, it is Miss Price; I am certain of its being Miss Price.” And there was a half–smile with the words, which meant, “I do not think you would answer the purpose at all.”
"You always contrive to keep out of these scrapes." Really, Julia?
Mary Crawford's kindness to Fanny when she becomes the prey of her narcissist, reputation-ruining and home-wrecking brother. She gives up quite quickly.
"Let other pens dwell on guilt and misery. I quit such odious subjects as soon as I can." She picks the one novel of hers where this is a Blatant Lie to say this!
Edmund may not be as snarky as Austen's other heroes, but he has his moments:
Edmund: You look tired and fagged, Fanny. You have been walking too far.
Fanny:No, I have not been out at all.
Edmund: Then you have had fatigues within doors, which are worse. You had better have gone out.
