Maria & Henry’s affair and elopement also affected:

Julia marries a man who would not have otherwise succeeded. Considering how she made her choice it seems she will be happier than she deserves. Mr. Yates however seems to get just what he wanted since he has been interested in Julia since Lover’s Vows:

She [Julia] had been allowing his [Mr. Yates] attentions some time, but with very little idea of ever accepting him; and had not her sister’s conduct burst forth as it did, and her increased dread of her father and of home, on that event, imagining its certain consequence to herself would be greater severity and restraint, made her hastily resolve on avoiding such immediate horrors at all risks, it is probable that Mr. Yates would never have succeeded. She had not eloped with any worse feelings than those of selfish alarm. It had appeared to her the only thing to be done. Maria’s guilt had induced Julia’s folly. (48)

Julia & Mr. Yates are redeemed a little:

Julia’s match became a less desperate business than he had considered it at first. She was humble, and wishing to be forgiven; and Mr. Yates, desirous of being really received into the family, was disposed to look up to him and be guided. He was not very solid; but there was a hope of his becoming less trifling, of his being at least tolerably domestic and quiet; and at any rate, there was comfort in finding his estate rather more, and his debts much less, than he had feared, and in being consulted and treated as the friend best worth attending to.

Tom is completely redeemed. Although illness had done its work on Tom so also did his sister’s folly:

There was comfort also in Tom, who gradually regained his health, without regaining the thoughtlessness and selfishness of his previous habits. He was the better for ever for his illness. He had suffered, and he had learned to think: two advantages that he had never known before; and the self–reproach arising from the deplorable event in Wimpole Street, to which he felt himself accessory by all the dangerous intimacy of his unjustifiable theatre, made an impression on his mind which, at the age of six–and–twenty, with no want of sense or good companions, was durable in its happy effects. He became what he ought to be: useful to his father, steady and quiet, and not living merely for himself. (48)

Mr. Rushworth is released from the trials of a discontented wife to indignity and disappointment but he has the opportunity to procure a more amiable wife:

Mr. Rushworth had no difficulty in procuring a divorce; and so ended a marriage contracted under such circumstances as to make any better end the effect of good luck not to be reckoned on. She had despised him, and loved another; and he had been very much aware that it was so. The indignities of stupidity, and the disappointments of selfish passion, can excite little pity. His punishment followed his conduct… He was released from the engagement to be mortified and unhappy, till some other pretty girl could attract him into matrimony again, and he might set forward on a second, and, it is to be hoped, more prosperous trial of the state: if duped, to be duped at least with good humour and good luck… (48)
