I'm just going to start by saying that this was my second Fanfiction ever written. I don't know whether I like it that much, but my friends seemed to, so here I am... Posting it now. I hope that you enjoy it. Reviews are always appreciated. Thank you for reading! :) I do not own Sherlock or the characters... Blah, blah, blah.

The Evil Girlfriend

John Watson. To the newspapers he was known as 'Bachelor John Watson'. But to his best friend Sherlock, it was just simple John. He always was under the impression that Sherlock wouldn't really risk his life for him. He thought that he didn't care. However, when one of his girlfriends turned ugly, Sherlock was the first man on the scene.

Chapter 1
"Sherlock..."

"And this is the place where it all happens."

Sherlock sighed. He'd heard that introduction many a time before this. To be honest he was really rather bored of how many women John dated. It was always the same. 'Welcome to the den.' John would introduce the woman to Mrs Hudson. She'd offer them tea, but both parts of the party would refuse. John would then twirl and pull the woman's hand upstairs. Then he'd lead them into the flat. 'And this is the place where it all happens.' That was Sherlock's favourite bit. He would always mimic John, just before he and his new lady came into view.

"So this is the famous Sherlock Holmes?" This woman's voice was sweet, and light. There was no sign of stress, nor nervousness. She was calm and different from the other women. On the other hand, nobody had ever said that when they entered the flat. Everywhere you could see there was books and different experiments laying around.."Hello. I'm Brooklyn Jones." She set out her small and rather delicate hand towards the aggressive looking man that sat before her. Sherlock didn't pay much attention to her, but then again, he never was very interested in the women that John managed to drag back to their flat.

"Sherlock. Are you going to say anything?" John stood next to Brooklyn, his arms were folded in a very camp way. His eyes looked at Sherlock's non-moving expression. "Would you like a cup of tea?"

Brooklyn frowned at John; she'd wanted to meet Sherlock Holmes like nothing she'd ever wanted. Ever. "Sure. White, two sugars please." She turned around and pointed at the armchair that stood behind her. "Is it okay if I sit here?" Sherlock immediately pounced at her. John knew what Sherlock was about to say. He'd known Sherlock for too long not to know. Sherlock only thought about his experiments, and if someone touched them; they'd be sorry.

"Do you know what happened to the last of John's girlfriends when she touched one of my experiments?" Sherlock's eyes squinted, but he still managed to raise his eyebrows without looking like a clown in pain. He pushed past her and picked up the jar. "I'll give you a clue..." He smirked. His hand slowly raised and pointed at the shattered window.

"Oh. What's this John? It's a... Ugh. It's a box of thumbs." She closed the box and threw it at John's fragile stomach. "Why do you have a box of thumbs sitting on your sofa?" The girl scrunched her face up in disgust.

A few moments later, she was lying outside of 221B. 4 of her ribs were not only broken, but completely shattered. Her head was flowing like the river Nile. As it left, her hair became a big swimming pool; the dark red colour of the nail varnish that she wore. Her left lung was punctured straight through. She had asthma so already found it hard to breath, but this made it even worse as time went on. Her necklace practically strangled her, as she lay broken and almost dead on the floor. Her legs, bent in ways that Sherlock had never seen, made her seem like a puppet that was just dropped from it's owner's clutches. She could barely speak but a simple 'Ouch' managed to escape her trap every few minutes.

John turned and looked at the dark man that stood behind him. He stared and enjoyed his work. "Sherlock..." John's rough hands pushed Sherlock away as he threw himself towards the door. "I'm coming Alice!" John screamed down the stairs. Sherlock simply smirked. He was glad that he could finally show John what he could do.

After John returned from the hospital, where he'd laid on Alice's bed-side for the past 5 hours, he punched Sherlock's sculpted face. "What the FUCK was that for?" John's anger was now released. Sherlock had just thrown his girlfriend out of the window, and he didn't even go to see if she was alright. Instead he remained in his seat and practised playing his violin."All she did was touch your precious box of thumbs. So, what. You throw everyone out of the window who touches your precious experiments?" John continued to shout. His heart rate started to increase. Sherlock sat in his armchair, legs crossed and fingers placed correctly over every string of the violin. He looked up at John and smiled.

"No John. It wasn't that she touched my experiment." His eyes returned to their forward position. John placed his hands on his hips, anger re-filled his face.

"Oh, so what was it?" He wanted and answers, and Sherlock would give them to him. Even if he had to beat it out of him. And this time he wouldn't miss his nose nor his jaw. "Sherlock!"

Sherlock chuckled to himself. "Well if you really want to know, John." He raised out of his chair and put the violin in the place where he'd sat. "She had an annoying laugh..." He walked past John's open-mouthed face and strolled quickly into his bedroom. John would never attempt to attack him in there. He'd always promised that he's burn his jumper collection if he even took a step in there if it wasn't necessary. He was safe.

(Back in present time)
"She touched your thumbs, but you threw her out of your window..." The dark blue eyes of the woman that stood before Sherlock looked right into his. "Because she had an annoying laugh?" Her eyes returned to the window. She walked slowly towards it, admiring the work that Sherlock had done. "I suppose that's legit..." Brooklyn smiled to herself, she was only teasing Sherlock, seeing how he would react.

"Brooklyn...?" John was disgusted. He looked, in turns, at the two people that were in the flat with him. "How could you say something like that?" She turned to him, placing her hands around his neck. She leaned her head against his shoulders. "Oh, you were joking." It took John a few seconds to realise what he had just witnessed, but he started to fold his arms around her ribs. He could feel every single one of them perfectly. In many ways it was like hugging a skeleton.

"John, I have to go now. Sorry about the tea and everything. We should do this again some time." Her smile brightened up John's eyes. The sun's light behind her made her hair twinkle and shine. It almost blinded John, but he didn't flinch. He liked what he saw. His hands lead her downstairs and he kissed her on her golden cheeks.
