'I don't want some girl coming in here and interfering with MY cases' Sherlock whined as John cleaned around him

'Cases?' what cases, Sherlock? You've been stuck in here going insane for weeks now,' John lifted up a bag of questionable body parts from the fridge and promptly threw it in the bulging dustbin,' anyway Sherlock it may be enjoyable, you may even have fun, o wait, no, you don't know fun. Now stop standing on the coffee table! I just polished that'

John smirked to himself on his last remark. He loved getting over on his flatmate. The sound of a taxi and voices floated through the open window.

'O God they're here,' Sherlock looked up at John as he ran to his armchair,' Sherlock, for the love of God act nor-'

Mrs Hudson entered, a beaming excited smile on her face, she clapped her hands as she spoke.

'Boys, this is Kitty' John and Sherlock both raised interested eyes at the door. Jon expected a small child to be dragged in. Instead, a girl shyly wondered in, clutching a suitcase in her hand. She stood uncomfortabley at Mrs Hudsons side and leaned onto one foot, trying to act naturally. She quickly placed her other leg down so she was balanced. The light coming in from the windows marked out her petite figure, shadowing her back and half her sculpted face. She reminded John of someone. Her personality appeared similar to her stance; anyone could tell she was nervous. She was shy quiet. On her right finger she wore a ring. Her slim, pale hands had a few bruises. She kept tucking a rogue curl of her thick hair behind her ear and rubbing her arms. She wore a long red sweater and dark jeans covered her thin legs and a pair of black studded boots. John averted his stare so not to appear creepy. He shot her a kind smile.

'Dr John Watson' he got up and shook her hand, she was freezing.

'Nice to meet you' her smile was kind and gentle, her lips were a rosy red. Her voice was calm and had a sweet tone. John noticed her shining green eyes rest on the silent figure which sat to her left.

'That's Sherlock Holmes,' the girl looked fully to her left, the man stared back at her. His hands were together in front of his face with just his fingertips touching. As he acknowledged her staring back he quickly turned his head to the side and stared at the wall,' don't take it personally, he's having a bit of a tantrum.'

The girl smiled politely again. She still appeared nervous so John smiled back at her.

'Adopted' came a deep voice. Both the girl and John jumped. Realising where it came from, Johns heart dropped, Sherlock was off.

'Pardon?' the girl fully turned towards Sherlock. He turned back from the wall and met her curious eyes. He cleared his throat and pushing off the arms of his chair rose to his feet. He towered above the girl.

'You're adopted'

'How do you-'

'Sherlock don't start' John's voice had an air of warning to it. He went to grab the girls arm which hung at her side. But she didn't budge.

'Firstly, you're stance. You are nervous so are evidently used to standing in front of people and having to make a good impression, to be judged by them. You are about 20? I say about 20, you're exactly 20 so too young for any business job. Now your accent-'

'What about my accent?'

'Don't interrupt. You got the first train down from Edinburgh…'

'How...'

'Look, if you keep interrupting I won't continue. Your eyes have slight bags underneath; you're tired so you've been up earlier than usual. You arrived in a cab so you didn't drive, so train it is. Now from Edinburgh, you have not one, but three sets of the whole punched left overs of train tickets stuck on your coat so you've changed trains multiple times. And your coats wet, yes, its raining here but your coats damp and the walk from the cab to here was short so where was there the last rain storm?' He thrust his phone in her face,' Edinburgh, approximate time at 6 o'clock this morning. But yes you're not Scottish are you, you have a London accent? There's nothing to draw a young, attractive girl of 20 all the way up to Scotland? You live there with adopted parents'

John looked at the girl warily. The girl smiled and her eyes lit up.

'That was-' she gasped

'Brilliant, amazing, wonderful' Sherlock rose to his feet and smirked at her,' John's already expressed that multiple times.'

The girls smile widened on her red lips.

'Don't interrupt Mr Holmes,' with a flick of her hair she walked towards the door, this was when she turned and looked at the strange pair,' nice to meet you Doctor Watson, and you, Sherlock'
