Elizabeth is then in the throes of the more disturbed, more unequal spirits that Jane had undergone when Mr. Bingley returned to Netherfield. Her hopes are less stable, her fears more overwhelming; she assigns triumph to Mr. Darcy's hypothetical reactions, while generously allowing that he has a right to it. The reader has the comfort of knowing that she is wrong in expecting it of him, however.

When Elizabeth gave the 'stupid men' speech, she was being more cynical than usual. When her relationship with Darcy is in suspense and doubt, she thinks more erratically than usual. So, in the first instance, she is becoming more like Mr. Bennet, and in the second, more like Mrs. Bennet! Luckily, she never takes either to the extremes she witnesses often at home, or the reader might cease to like her. ;)
