I've grown to enjoy the "villians" of P. if they can be called that -- Sir Walter, Mr. Eliot, Louisa (more of an impediment to the plot). They are lively.

1) Mr. Eliot sitting in his room wandering about the party next door.
2) SW sitting at a cafe and rating the women.
3) Louisa jumping off the steps at Lyme.

Why does JA give these characters interesting, idisyncratic actions? Mr. Eliot thinks it "ungenteel" to ask questions at an Inn -- an odd mind. Louisa, in the manner of a man, pressing her attentions on FW.

JA clearly enjoyed writing about them, though she cruelly punishes Louisa for her boldness.
