It was a quiet day on baker street, which Dr. Watson knew would make Sherlock Holmes particularly unbearable. Last time he had checked on him he was just staring into space with a dazed look on his face, Watson prayed to god he wasn't using again. Yes it was a quiet day, and quiet days are meant to be interrupted, but it still surprised Watson when a knock came to the door. Watson, of course, answered it without hesitation, and was extremely surprised to see a a girl, of 16, standing there. She was dressed in a way that was not proper for a Sunday afternoon, and the girl seemed quite aware of it.

Her attire was a pant suite with a skirt over top to make it seem more like a dress, but it was obvious it was not. She walked inside the flat without hesitation and breezed past Watson as if he wasn't even there. On her way to the staircase she stopped suddenly, as if she'd just realized it was rude to walk past someone after barging into their homes, a characteristic Watson was used to.

"I'm sorry Dr. I almost forgot you were there" her British heritage was evident in her voice so Watson knew she must live in England.

Watson didn't seem to get much else out except "How did you know I was a doctor?"

"Well obviously you're a doctor an army doctor at that" she answered, causing Watson to flash back to the first time he met Sherlock Holmes. "The mail here is addressed to either Sherlock Holmes or Dr. John Watson, since you are not Sherlock Holmes, you must be Dr. Watson. As for the army part, it's in you're posture Dr. The way you hold yourself, like a soldier. And I know no other kind of person that carries a blade in their cane" She tilted her head towards the door where Watson's cane leaned against the wall.

"That could be Holmes'" said Watson continuing to test the girl.

"The engraving says otherwise" She smiled "Now I must see Sherlock Holmes" she turned to the stairs.

"He doesn't like strangers" warned Watson, following the girl up the stairs but making no attempt to stop her.

"I'm many things Watson, but I am no stranger" Watson was slightly taken aback by being addressed this way, the only other person who called him that was...

"Sherlock!" cried the girl as she entered, Holmes stiffened the moment the word left the girl's lips.

"Oh good god" muttered Holmes, the girl pretended to look offended.

"Not happy to see me Sherlock?" she asked pouting.

"Not at all, Cordelia, I am ecstatic to see you" Holmes finally turned around to face Cordelia, the look on his face was not ecstatic, in fact it was almost to the point of loathing.

"Still seeing that awful woman" said Cordelia, it wasn't a question, it was an observation.

"It's been weeks" Lied Holmes

"Since you've started" Cordelia narrowed her eyes "She's bad for you Sherlock"

"I wish you would stop calling me Sherlock" said Holmes taking a swing of an unknown substance in a bottle beside him on a table covered in god knows what.

"I will, the second you stop calling me Cordelia" she answered.

"Never" he seethed.

"Well then Sherlock-" Holmes cut in

"Honestly!" he exclaimed

"Would you rather me call you brother?" she asked, now annoyed.

"Wait a second, Brother? You two are-?" Watson was bewildered

"Siblings, yes" Holmes answered Watson's question, Cordelia turned her back to Holmes to face Watson.

"Cordelia Holmes, pleasure to meet you, shame Sherlock hasn't introduced us before" Holmes flinched at his name, as Cordelia shook the hand of a very confused Doctor.

"You two are very-" started Watson.

"Similar? I suppose so" Cordelia finished and answered Watson's question. "Some say we even look alike"

For the first time since she walked in Watson took a proper look at Cordelia Holmes. She had very dark hair, but it had been cut short and the remaining loose pieces tied back. She was a couple inches shorter than Holmes but when she stood in front of him, she almost looked taller than he. She was most likely no more than 16 but looked 17 or 18. She didn't wear much make-up but she didn't need the little. There was something in her features that made her uncharacteristically beautiful, strange, especially being related to Holmes.

"So, why are you here?" asked Holmes, though he had answered the question himself already.

"Why else would I be here?" Cordelia rolled her eyes "You always were less intelligent than I"

"So I'll see you tomorrow?" asked Holmes

"of course" she answered

"Noon"

"When else"

"White haven"

"indeed"

"Fine"

"Fine" Cordelia looked at Holmes for a moment before turning to leave, but she hesitated. Before she managed to get out the door she turned her head back to Holmes and said "Bring Watson along"
