Extending Fall to a long story seems quite a project, so just do something simpler. :D
In here Mr. Woodhouse is less valetudinarian, so Emma visits town regularly. And Mr. Wickham is borrowed from P&P for certain reasons.
"Mrs. Knightley, so delighted to see you again!"
"Mr. Wickham, how are you! What a surprise to see you here."
"It's been a long time. I trust you and your family are all in great health."
"We're very well, thank you Mr. Wickham. Have you been in town for long?"
"Oh no, just arrived yesterday. But I will stay here for some time, for business. And I always remembered the great help and kindness Mr. Knightley has rendered to us."
"You are too polite, Mr. Wickham, it's nothing. I believe Mr. Knightley was very glad to be helpful. He always wishes to do something for the soldiers who sacrificed themselves for the country."
"Yes, I'm very much convinced that Mr. Knightley is just what a man ought to be."
"You are very kind, Mr. Wickham. Do you enjoy the party?"
"Very much indeed! Every arrangement is wonderful, the decoration, the light, the food. And all guests are polite and friendly, not to mention the lovely and amiable ladies. And they say that most brilliant young lady, who is now dancing with Sir Blake, is your sister."
"Yes!" watching Emma whirling in the dance floor like a moving rosa rugosa, drawing admiration from almost every gentleman, Isabella could not be more affectionate as a proud sister.
"Emma!" When the music was over, Emma looked around and came happily to her sister. "This is Mr. Wickham." Isabella motioned to the handsome young captain standing by her side, "My sister, Emma Woodhouse."
"So glad to make you acquaintance, Miss Woodhouse."
"How do you do, Mr. Wickham."
"I have heard so much about you, Miss Woodhouse, your goodness and accomplishments."
"You flattered me, Mr. Wickham," Emma laughed, "I know many truly accomplished young women and would like to introduce you to them if you wish."
"If I have the luck and chance. But for now my only wish is that you could do me the honor of dancing with me for the next."
"My pleasure."
"So you have known John and Isabella for years."
"Literally yes, but not quite. We only intersected for once and I seldom came to town."
"Where do you live?"
"I do not possess an estate or even a house, I stay at military bases."
"Military bases? Must be very attractive."
"Yes, energetic and aspiring, very different from the prosperity of town and the tranquility of country."
"Which one do you like best then?"
"I like them all, each in its own way is irreplaceable."
"Ha, you are very insatiable, Mr. Wickham." said Emma playfully.
"Then which one do you like better, Miss Woodhouse, London or the country?"
"I like Highbury best." Emma stated without a tiny hesitation.
"I'm not lucky enough to have ever been there, but I'm sure it's a very pleasant place with very amiable people."
"You are right, it is indeed."
"I grew up in a grand country house too, with splendid landscapes and kindest people. The late master of the estate was my godfather and loved me like a second son, patronizing me to Cambridge and even leaving me a living in the church."
"But you are not a parson now for sure?"
"No, I'm not. It's a less pleasant story and all my connections to my childhood home has now dissolved thoroughly. But to respect the late kind gentleman I'd rather never reveal the truth again."
...
"How do you like Mr. Wickham, Emma?"
"He is pleasant, amiable, conversable, has very good manners and characters, very well bred, seemingly very well educated too. He has great experiences on travels, social matters and personal affairs, willing to talk and also talked in a very open and honest way... In every respect he is perfect, faultless.
"And extremely handsome too."
"Yes, very handsome, I hardly see any man handsomer than him, features or figure. But..."
"But what?"
"I don't know. Something is just not right."
"Perfect to a fault?"
"Perhaps." Emma furrowed her eyebrows, trying to figure out what was perplexing her, what's wrong with this universally admired young man. "He is very open and very modest, being satisfied with and giving compliments to almost everyone and everything he encountered, even the evils can remind him to cherish the merits more.
"That's a very rare virtue I dare say."
"Maybe. But I just got an odd feeling, a very odd feeling that it's only a disguise."
"Disguise? Disguise for what?"
"Boasting. Boasts covered by his disarming modesty. He seems too eager to show all his merits to the whole world at one time." Emma raised her eyebrow, seemingly having done with being interested in this new acquaintance, and simply concluded, "Mr. Knightley will never talk too much about himself, especially to the ones he meets for the first time."
"John, I believe you need to talk to George."
"About what?"
"He has too much influence on Emma."
"Is that bad?"
"Generally not, but..."
"But?"
"Emma has raised her standards of men so high that no one could delight her eyes, let alone her heart."
"You are not considering an alliance with Mr. Wickham?"
"Of course not, it's a pity that he's not Emma's equal. But Emma's opinion of him is a dangerous sign, what else kind of character can satisfy her, saving your brother's? I don't want Emma to become a spinster for sure."
"What do you wish me to do then? Talk George into being mean and wicked?"
Isabella laughed, "It seems a hopeless case."
