With much uneasiness did she thus leave them.

It seemed to her that Captain Tilney was falling in love with Isabella, and Isabella unconsciously encouraging him; unconsciously it must be, for Isabella's attachment to James was as certain and well acknowledged as her engagement.

To doubt her truth or good intentions was impossible; and yet, during the whole of their conversation her manner had been odd.

She wished Isabella had talked more like her usual self, and not so much about money, and had not looked so well pleased at the sight of Captain Tilney.

How strange that she should not perceive his admiration! Catherine longed to give her a hint of it, to put her on her guard, and prevent all the pain which her too lively behaviour might otherwise create both for him and her brother.
The compliment of John Thorpe's affection did not make amends for this thoughtlessness in his sister.
