Disclaimer: Jane Austen owns all of the characters mentioned. The clergyman from Pemberley is mentioned in Jane Austen's Memoir, but I did make up his name.
Potentially Problematic
Mary Bennett, having finally gotten the nerve to inform her parents that she wanted to visit her relations London for the first time, at the age of twenty-six, walked slowly down the crowded street. Her aunt Mrs. Philips had her arm interlocked in hers, but her full attention was given to the recently-engaged Kitty, who was to be married to a clergyman who resided near Pemberley.
Mary's mind wandered freely as her body was pulled in and out of the various shops that caught the fancy of Mrs. Philips or Kitty. Generally, these were related to fine, expensive clothing or cosmetics, none of which interested Mary whatsoever.
'Well,' Mary mused, 'We have dear Jane married satisfactorily off to Charles Bingley, and Lizzie to her peculiar Mr. Darcy.' Abruptly, a man bumped rather harshly into Mary, and as he stammered an apology she merely glared at him and continued to half-look at the ribbons that Kitty was currently fussing over through a store window.
'And of course there's Lydia to her charming Mr. Wickham,' she thought sarcastically, moving now into a restaurant, where the two shoppers had decided to eat a quick dinner, 'And at present Kitty has her corpulent but fine enough Andrew Flemyng.'
A serving woman interrupted Mary's reverie.
"And for you, miss?"
Mary gave a small scowl – she hated being interrupted when she was thinking . "A cup of tea, please."
"Very well."
Kitty and Mrs. Philips began to comment on the vulgar fashion choices of the restaurant-goers around the trio as Mary's mind wandered once more.
'Who may Mary have?'
Mary, almost as if sleepwalking, rose from her chair and drifted over to the piano. Kitty and Mrs. Philips took no notice.
Her hands running across the worn, smooth wood of the lid, Mary instinctively searched for the name of the maker. 'Is it a Broadwood?' she wondered, legitimately curious. Pianos and music were her passion, and this piano was indeed a sight to behold, even though it was housed in a restaurant.
"Tis a Collard and Collard," a strong, male voice said from behind Mary. She gave a small jump and turned around.
"I'm sorry if I startled you, Miss," the source of the voice, a fine-looking man no older than thirty and two, said warmly, "You just appeared so intrigued."
Mary blushed and for once was at a loss for words. No genuinely attractive male had ever approached her before, much less began a conversation.
"Indeed, thank you for your information," she said, trying to somehow sound both intelligent and innocent simultaneously, as the heroines in her favorite novels did.
"It is my pleasure, Miss," he smiled.
Mary decided to continue the conversation. "Pray tell, sir, what is your name?" she inquired boldly.
The man grinned and rested his hand gently on the piano, mere inches from Mary's.
"Mr. Willoughby."
A/N: Le gasp! Don't worry, Mary doesn't end up with flirty Willoughby (poor Marianne!), but in Jane Austen's Memoir Jane mentions that Mary marries "nothing higher" than a clerk of her uncle Philips.
