"So how long are you in town for?" John asked politely as he and Leila watched Sherlock and Molly debate about what type of ink was used.

"As long as I want, I guess." Leila answered. She took a long sip of the tea that Dr Watson kindly made for her. John nodded, his eyes narrowing as he watched Sherlock snatch the glass slide off of Molly and rudely ignored her attempts of conversation.

"You and Molly must get along very well, if it was my sister coming to stay I'd have a date set on when she'd be leaving and I'd be counting down the seconds." John laughed, he slowly raised his mug to his lips and took a small sip of his coffee. Leila smiled and placed her mug down on the desk that she's perched on.

"That reminds me." She replied. Smoothly jumping off the desk she made her way over to her older sister, who appeared to be transfixed on the detective looking through the microscope. "Hey Molly." Leila sang sweetly, tilting her head to the right and an innocent smile covering her face. Molly jumped slightly not knowing that her younger sibling was so close.

"What do you want?" Molly answered looking at her sister accusingly. "Oh god. You've broken something haven't you?" Molly squealed, her eyes widening and frantically beginning to search around the room for any broken equipment.

"No, no! Everything is fine." Leila reassured, Molly instantly began to relax a natural smile returning to her face. "It's just...I need a place to stay and I was hoping you would say yes." Molly's face fell for the second time, she stared down at her sister.

"I thought you were staying at a hotel!" Molly panicked. "Where's your stuff? Why didn't you ask me earlier?" Her voice raised higher and higher catching the attention of the doctor at the far end of the room, however Sherlock didn't even flinch his eyes still fixated on the scraping of ink they managed to get off of one of the victims.

"I only arrived this morning and I came straight here. I have no money, so that rules out me stating at a hotel. And as for my stuff, it's currently stuffed in my car which has barely any petrol in it. I didn't tell you because truthfully, I kind of forgot. Has that answered all your questions, sister dearest?" Leila answered, a weak smile remaining on her face. Molly stayed silent, her eyes wide and her face paling.

"I...Urmm...I mean, that...Urmm..." Molly stuttered, her eyes still locked on her younger sister.

"Will you just spit it out!" Sherlock's voice interrupted, annoyance lacing every word. Molly flushed scarlet and averted her gaze to stare at her shoes.

"Sorry, it's just. I'm staying at a friends house due to the fact that there has been a gas leak in my apartment. I would say that you can stay but Susan isn't very..."

"It's ok, I can tell when I'm not loved. I did live with our parents for eighteen years, remember?" Leila interrupted, shrugging her shoulders and placing her hands in her front pockets. Molly's mouth hung open.

"No. That's not what I meant. I was going to lend money for you to stay in a hotel." Molly rushed, she quickly walked over to her bag and pulled out her purse. John placed his empty mug next to Leila's abandoned tea, he quietly headed in the direction of the Hooper sisters.

"Molly, you don't have to pay for a hotel. Leila can easily..."

"No John!" Sherlock spoke up once again, finally averting his eyes from the lens of the microscope and glaring in the direction of his friend.

"Why not?" John argued back, Molly and Leila exchanged confused glances before continuing to pull the money out of the battered leather purse. John reached out and grabbed the purse out of Molly's grasp.

"Because I said so." Sherlock responded standing up and reaching for his coat which he had neatly placed on the back of his chair before examining the ink sample. John scoffed, Leila opened her mouth to speak but Molly shot her look that screamed 'don't'.

"Well I say yes, do you have any idea how much staying at a hotel costs in this part of town?" John replied. He turned to Leila as if the argument did not just happen. "How would you like to come live at 221b?" John asked smiling at Leila who seemed to have a dazed expression upon her face.

"Sure, thanks?" Leila answered quizzically unsure on whether to answer. John turned back to the taller male who seemed to be frowning down at him.

"Then it's settled. Leila shall be staying with us for as long as she needs." John announced. "Plus, it'll be saving Molly money." he added in hope that it might convince Sherlock even more and wipe the icy glare off of his face.

"She is not staying. For one reason, there are only two bedrooms and two, she would be an annoyance, just an inconvenience to me." Sherlock said rudely. "We have to go now John." Sherlock turned and headed towards the exit. John frowned, he opened his mouth ready to shout back.

"I don't mind sleeping on the couch." Leila's voice interrupted. She walked over to the worktop and picked up a set of keys. "And I also own a car, so you wouldn't have to flag down a taxi to take you everywhere." she teasingly swung the keys around her fingers, smirking at the back of the detective that had stopped mid stride.

"See not such of an inconvenience now, is she?" John added walking to stand next to her. Sherlock turned suddenly, marching over to the grinning pair.

"Fine. But if you so much as touch any of my experiments, annoy me in some way. You will go." Sherlock hissed, Leila locked onto his eyes and nodded. He turned back in the direction he just came and angrily pushed open the double doors. "Hurry up. We need to go." Molly hugged her sister and placed a ten pound note in her hand.

"Petrol money." Molly whispered.

"Thanks." Leila responded, folding it up and placing it in her pocket. She looked up to her sister, someone she has been envious of for her whole life. Molly was perfect in their parents eyes where as Leila, she was just always in the background. The freak. "Bye." Leila turned and headed in the direction of the impatient detective.

"I would like to leave, now." he called out, John walked ahead of Leila who smiled once more to her sister as she passed through the exit.
