as there is never one that satisifes me with regard to Emma.its all there in Chapter 20.even the information that Jane Fairfax has always been resreved,and not jsut when she had a guilty secret to conceal ;-)

Emma was sorry to have to pay civilities to a person she did not like through three long months! to be always doing more than she wished, and less than she ought! Why she did not like Jane Fairfax might be a difficult question to answer; Mr. Knightley had once told her it was because she saw in her the really accomplished young woman, which she wanted to be thought herself; and though the accusation had been eagerly refuted at the time, there were moments of self-examination in which her conscience could not quite acquit her.

And as to playing in a superior manner, she should just not have done it-that Jane Fairfax.She cetainly could have performed something simple, knowing that her hostess played too.She is not quite the thing, to quote Mr Woodhouse.I speak as a relatively comteant musician.She could have reigned her talents in for the sake of her hostesses feeling.
