With the rest of the group still tending to the Stitch issue, Rarity had left prematurely with her sister following alongside. It had been a fairly close shave, but the two had made a promise to each other not to speak of Sweetie Belle's unusual condition unless absolutely necessary. The other ponies didn't need to know, they wouldn't understand. Rarity leaned down to nuzzle her younger sibling, and gave her a nudge.
"Go play now, and stay out of the basement. There's dust and moths and all sorts of horrible things down there," she warned. "Nothing that you need to be getting yourself into."
Sweetie Belle ran off to do whatever it was that she did, and Rarity continued her work. She had made mention several times of an important parcel due to an important client, but had made no mention of what it was or who it was for. All part of the deal with its benefactor, she did not speak of it and thus retained exclusive seamstress rights, as well as a sizable commission..
The sun passed lower in the sky, and with only an hour to spare, Rarity finished. She looked down at the work in front of her, fanning herself with a scarf. She never did find out exactly what had happened with Stitch until after the fact, but that was alright. She was a mare of business, and business took priority.
Rarity had only a few moments to herself before the front door chimed, and she quickly folded the clothing she'd been repairing and placed it in a box. Only then did she finally retreat to the front counter.
A stallion stood there, fairly neutral in color, a wide grin plastered on his face. He had only been in here once or twice before, every time leaving as mysteriously as the time before it. Rarity tended not to ask questions, because she knew he didn't like to give answers.
"Is it finished?" He asked.
"A lady always keeps her word," Rarity assured him, and floated the box into his saddlebags. "If you could just sign this document of receiving, our business here will be concluded." She was rather adamant about this, especially since the last few times the stallion had paid and left without any form of documentation.
"Of course," he said kindly, paying the rather substantial bits that were due, and scribbled quickly on the form. He nodded his head, and made a quick exit for the door.
Rarity scanned the document, and barked her disapproval at him. "Hold it right there!" She demanded.
To her surprise, the stranger did just that.
"Must you whine?" He asked.
"I'm not whining, I'm educating!" Rarity insisted. "There is a certain way that certain things must be done, otherwise the entire economy would fall into anarchy. See here, All you had to do was sign your name, so that I may have proof that you recieved your parcel. NAME, darling. Not occupation. Even so, what you wrote was hardly adequate. All you wrote was-"
"Doctor," the stallion replied patiently.
"Yes, but that isn't hardly fitting at all, now is it? Doctor of what? Or IN what? Doctor who?" Rarity asked.
The stallion just grinned. "That's the question isn't it? Thanks for the patch up as always, but very busy, must run. Perhaps I'll take you with sometime, who knows? Allons-y!" With that, he charged out the door.
Annoyed, Rarity delicately circled around the counter, then charged after him. "Now wait a moment! It's horribly uncouth to just walk out on a lady like tha-" She paused, finding herself talking to an empty street. Several passing ponies looked at her in curious wonder.
Rarity sighed. "I really hate it when he does that," she muttered, and turned to go back inside, the door closing behind her. Upstairs, Sweetie Belle called downstairs from her room, where she had been busy coloring.
"Rarity? Who was that?" She asked curiously.
The older sister looked out towards the street. "We may never know, Sweetie Belle. We may never know."
