and Catherine found, with some surprise, that her two young friends were perfectly agreed in considering Isabella’s want of consequence and fortune as likely to throw great difficulties in the way of her marrying their brother. Their persuasion that the general would, upon this ground alone, independent of the objection that might be raised against her character, oppose the connection, turned her feelings moreover with some alarm towards herself. She was as insignificant, and perhaps as portionless, as Isabella; and if the heir of the Tilney property had not grandeur and wealth enough in himself, at what point of interest were the demands of his younger brother to rest? The very painful reflections to which this thought led could only be dispersed by a dependence on the effect of that particular partiality, which, as she was given to understand by his words as well as his actions, she had from the first been so fortunate as to excite in the general; and by a recollection of some most generous and disinterested sentiments on the subject of money, which she had more than once heard him utter, and which tempted her to think his disposition in such matters misunderstood by his children.
Isabella wants to marry for money. She seems to place Frederick first because he is wealthier but when that fails she tries to crawl back to Catherines brother in which time she realizes she is just using people.
