] Upon meeting with Isabella after she had danced with CT, I thought it was rather interesting that Catherine didn't pick up on the fact that Isabella referred to him as just "Tilney": "I am amazingly absent; I believe I am the most absent creature in the world. Tilney says it is always the case with mids of a certain stamp." But Catherine just goes on to ask what Isabella wanted to say to her. (snip)

...Tilney Says

Isabella also says, in response to Catharine's not wanting to marry her brother:

"You know I carry my notions of friendship pretty high. But, above all things, my dear Catherine, do not be in a hurry. Take my word for it, that if you are in too great a hurry, you will certainly live to repent it. Tilney says there is nothing people are so often deceived in as the state of their own affections, and I believe he is very right. Ah! Here he comes; never mind, he will not see us, I am sure."

I never noticed this before! I mean I realize she was always quoting him as if he was her beau, but I didn't notice the familiarity of her calling him by his surname; no Mr. Tilney or Captain Tilney for Isabella! I'm almost positive, now, that she must have written to Tilney as well. Forward girl! I have a possible theory-- She felt assured of the Captains affections so she decided to write him; the "challenge" thus being over for Tilney, he moved on to Charlotte Davis.

It's nothing more than she deserves.

Thanks for pointing this out!
