This chapter is just a short letter from Amy to Arthur.
Amy is all mopey and homesick and a little passive aggressive in the letter – much like in real life.
She writes about meeting Mrs. Gowan and goes on and on how super-beautiful Pet is, and how much Amy is not nearly as beautiful, and how she totally could never measure up to the awesomeness that is Pet.
She adds that Gowan kind of sucks, and that Pet seems kind of unhappy, and that they are not that well matched as a couple. But still, Pet? Really very pretty. Yikes, Amy, put down the whip. We're thinking that horse is already dead.
In other news, Amy can't adjust to their new life and misses everyone from home. She wonders about the Plornishes, and how they are doing now that Dorrit bought them a business and they are able to have Old Nandy come live with them again. (That's a neat little bit of exposition there, right? Now we know what they've been up to!)
She also keeps expecting to find the prison around every corner and Mrs. Clennam's house on the next block. On top of that, she's super-sad that she isn't at Dorrit's beck and call anymore.
Finally she hopes Arthur thinks about her sometimes, and that he'll keep remembering her as the poor, raggedy girl he met, not the daughter of some rich obnoxious dude.
