This takes place sometime in season one, after the Blind Banker. Sherlock may be a little OOC around Stasia, but you'll see why. I don't own Sherlock, Watson, Mrs. Hudson or anything recognizable, except Stasia and her crazy guardians! ENJOY

221 B BAKER STREET

It was a cold rainy day in the city of London. No clients had come through the infamous door of 221 B Baker Street and Sherlock, being himself, took his mood out on the poor defenseless walls. Bang! "Bored!" Bang "Bored!" With each cry of the detective's mood, a shot went through the wall, shooting from a different angle each time (think the time in "The Great Game") Mrs. Hudson came up the stairs.

"Sherlock! What have you done to my bloody wall! It's going-"

"On my rent, yes I know Mrs. Hudson," the case-less detective said.

"Alright, good. Anyway, there's a young girl downstairs. She said she needed to see you. Something about the Kennelys."

"What does she look like? Don't leave out anything!" Sherlock said, shooting up, interest peaked.

"Well, she seems about 14 or 15, 167 cm (A/N: 167 cm= 5 feet, 7 inches ((roughly)) Sorry if I confessed you). Dark hair, grey-blue eyes, soaked to the bone. I offered her a cuppa something warm, but she insisted on seeing you," the landlady informed the detective.

"Then send the poor girl up!"

"Alright. Alright. I'll send her up! Patience, Sherlock!"

Mrs. Hudson made her way back downstairs while Sherlock hopped up. He started clearing a space on the coffee table and couch. The great detective then ran into the kitchen, rummaging through the cupboards, looking for something, which, in all likelihood, wouldn't be there.

"Sherlock! What are you doing?" John Watson said as he entered the kitchen.

"Cream! Do we have any cream?" Sherlock said, ignoring the doctor's question.

"Yes. In the refrigerator. Why?"

The front door opened. "Sherlock! Where are you?" The landlady, not a housekeeper, shouted.

"Kitchen!" came the hollered reply.

"Oh, my gosh! He's in the kitchen! The kitchen!" a mystery voice exclaimed. Mrs. Hudson came into the kitchen, followed by the owner of the mystery voice. Mrs. Hudson and a girl with dark curly hair and blue-grey eyes, carrying a backpack walked into the kitchen. The girl was wearing a green t-shirt, dirty jeans, beat up purple Converse, and an old black hoodie that looked at least a size too big on her. Her hair was up in a messy bun, and it looked as if she had had it that way for several days. And she was soaking wet from the rain outside.

"Well this is-"

"Excuse me! I can introduce myself! My name's Stasia. Yes, it's a nickname; no I'm not going to tell you my full name so don't bother asking." She turned to face the detective. "Hi, Sherlock." Stasia said casually.

"Hi, Stasia. You ran away," the detective said. "Really? What gave it away?" Stasia replied sarcastically. "The backpack."

"Sorry, who are you exactly?" a very confused John interjected. "What? Sherlock didn't tell you about me?" "No. I barely know anything about him, next to nothing about Mycroft. So who are you?" Sherlock heaved a deep sigh.

"John, Mrs. Hudson," Sherlock said, taking Stasia under his arm, "this is my baby sister, Stasia Holmes."
