What is Pip thinking about while waiting to go to Miss Havisham?

Pip was thinking about Miss Havisham's plans for him.

It was too early yet to go to Miss Havisham’s, so I loitered into the country on Miss Havisham’s side of town,—which was not Joe’s side; I could go there to-morrow,—thinking about my patroness, and painting brilliant pictures of her plans for me.

She had adopted Estella, she had as good as adopted me, and it could not fail to be her intention to bring us together. She reserved it for me to restore the desolate house, admit the sunshine into the dark rooms, set the clocks a-going and the cold hearths a-blazing, tear down the cobwebs, destroy the vermin,—in short, do all the shining deeds of the young Knight of romance, and marry the Princess.
