what does Austen say about Jane?

"They have both," said she, "been deceived, I dare say, in some way or other, of which we can form no idea. Interested people have perhaps misrepresented each to the other. It is, in short, impossible for us to conjecture the causes or circumstances which may have alienated them, without actual blame on either side."

Jane rationalizes things, in this case Wickham's stories about Darcy, the way she wants things to be.

"If it was to be secret," said Jane, "say not another word on the subject. You may depend upon my seeking no further.

Apparently Jane can keep a secret!
