Who's Jane Fairfax

I always figured Amber for Jane Fairfax.

Jane Fairfax serves three purposes in the novel:

1) She's the reason Frank Churchill could never have had feelings for Emma.

2) Emma is jealous when she thinks Mr. Knightley may have feelings for Jane Fairfax.

3) Emma finds her annoyingly perfect, and feels inadequate when people compare the two of them.

In Clueless, 'Frank' is gay, so that's reason 1) for Jane's existence taken care of. Reason 2) is fulfilled by Josh's brief girlfriend Heather; and since she's an intellectually pretentious college student, she fulfills reason 3) as well.

"I wish you to know that you have been the last dream of my soul."

It's partly Dionne. Heather is also mentioned here - and that's partly true, although her character is present only for a brief time. And by the way: Murray is - partly - Frank Churchill. Christian is - of course - the other part...
