Fanny was most conveniently in want of rest.

Crawford could not have wished her more fatigued or more ready to sit down; but he could have wished her sister away.

A quick-looking girl of Susan's age was the very worst third in the world: totally different from Lady Bertram, all eyes and ears; and there was no introducing the main point before her.
He must content himself with being only generally agreeable, and letting Susan have her share of entertainment, with the indulgence, now and then, of a look or hint for the better-informed and conscious Fanny.
Norfolk was what he had mostly to talk of: there he had been some time, and everything there was rising in importance from his present schemes.
Such a man could come from no place, no society, without importing something to amuse; his journeys and his acquaintance were all of use, and Susan was entertained in a way quite new to her.

For Fanny, somewhat more was related than the accidental agreeableness of the parties he had been in.

For her approbation, the particular reason of his going into Norfolk at all, at this unusual time of year, was given.
