A/N: Hello ;)

Okay, so this is such a random, random, random plot bunny that popped into my head. It's based on the modern Sherlock (I have an obsession with Sherlock recently), the second episode; The Blind Banker.

"So, what are these squiggles?" Sarah asked conversationally, leaning over Sherlock's shoulder to get a better look. I stifled a laugh at his annoyed expression.

"They are numbers, an ancient Chinese dialect." Despite the curtness of his reply, I was still surprised at the amount of 'kindness' he displayed. Sarah smiled, slightly awkwardly.

"I suppose I should've known that." Sherlock didn't respond. She turned to face me.

"Who are you then?" I shrugged.

"A sixteen year old girl tangled in this whole mess. Elisa Johnson's the name." Sarah's eyes widened.

"Wait, wait. You solve crimes with John and Sherlock? At sixteen? And the police allow that?" My shoulders rose and fell once again.

"Do I look sixteen?" I asked calmly, examining my nails. Sarah shook her head.

"No, more like nineteen. Twenty maybe."

"Precisely."

"What you're trying to tell me is that the police don't know how young you are." She stated, no longer surprised.

"Mhm. Officially, in the papers, my name is Elisa Holmes."

"You're posing as Sherlock's sister?"

"No, as his wife." I thought Sarah was going to have a heart attack.

"Bu- wha- that's…" She spluttered. I nodded patronisingly.

"We don't look anything like each other, the whole brother sister thing would've gone down the drain." Sarah took a deep breath. "But don't worry, we're not actually married." I added as an afterthought.

"What about adopted siblings?"

"Unrealistic. Sherlock's parents had two psychopathic children who saw and deduced everything. They also happened to be cold and heartless. Do you honestly think they would adopt another kid?" Silence greeted my response.

"This is messed up." She finally blurted out.

"It sure is. Takeaway?" Sarah gaped.
