Which lines in this excerpt from Jane Austen's Pride and Prejudice suggest that Mr. Darcy is questioning his hasty judgment and has fallen in love with Elizabeth
{Occupied in observing Mr. Bingley's attentions to her sister, Elizabeth was far from suspecting that she was herself becoming an object of some interest in the eyes of his friend}. {Mr. Darcy had at first scarcely allowed her to be pretty; he had looked at her without admiration at the ball; and when they next met, he looked at her only to criticise}. {But no sooner had he made it clear to himself and his friends that she hardly had a good feature in her face, than he began to find it was rendered uncommonly intelligent by the beautiful expression of her dark eyes}.{ To this discovery succeeded some others equally mortifying. Though he had detected with a critical eye more than one failure of perfect symmetry in her form, he was forced to acknowledge her figure to be light and pleasing; and in spite of his asserting that her manners were not those of the fashionable world, he was caught by their easy playfulness}.{ Of this she was perfectly unaware; to her he was only the man who made himself agreeable nowhere, and who had not thought her handsome enough to dance with}
