Chapter 1: Whatever Happened to Saturday Night

Lucy Watson was the famous Doctor John Watson's cousin. She was his aunt's daughter, and she never lived anywhere other than Cardiff. The two were exceptionally close for having an age gap. Lucy was 23, but mature for her age. Her friends were all older than her, and she was always good friends with her older cousin. She kept in touch with him via emails and texts. But then he moved in with the great Sherlock Holmes. Lucy was the doctor's number one reader. She pleaded for him to bring Sherlock to a family gathering, but he never would. Lucy always let him have it, cross with her cousin for not sharing his famous roommate and friend.

But then one day, Lucy got her wish. She was always a rebel, a trouble maker, a rule breaker. Her mother and father didn't know what to do, until one day their lovely nephew from Baker Street dropped by. Lucy was in her room, reading some book when she overheard the conversation happening just down the hall.

"But, John, don't you think Lucy's a little too young to be in London?" her mother said. Hah. She was just the right age to be in London.

"Don't worry, auntie. She'll be with me, and Sherlock, and good ole Mrs. Hudson. She'll be well taken care of," she heard her cousin say. She set the book down and sat beside her door at the mention of Sherlock. He continued on by saying, "And then there's Sherlock's brother. He can keep a good, safe eye on her." Lucy rolled her eyes. She read John's blog, and knew that Mycroft Holmes practically ran the English government. She'd be followed around by government lackies with no brain, all brawn.

"So she'd be safe?" piped up Lucy's father. Lucy rolled her eyes again.

"Of course. There's no where safer to be in London than 221B Baker Street," coined her older cousin. She could practically hear the passing glances between her parents.

"Go tell her, John," she heard her mother say. Lucy shot up and ran to her bed. Just as she had her book opened, her cousin walked inside. He shut the door behind him, and she shot him a glance. "John! I didn't-" she started, but was rudely interrupted.

"You heard everything didn't you?" John asked with a smile. Lucy laughed and nodded.

"Am I really coming with you to Baker Street!?" she asked excitedly. All she heard John say was "yes" before she shot up. She started packing as he talked on and on and on about how life would be like there. "You'll be living in the flat below us. 221C. You'll have it all to yourself, but don't get too crazy. Mrs. Hudson is very old you know," was something she heard while packing.

"I'll have my own flat?!" Lucy asked. There's no way her parents would agree to that. "Do Mum and Dad know?"

"Don't be silly, of course not. They think Sherlock's going to be in 221C and we'll have our flat," he answered. Lucy smiled and threw her arms around her cousin.

"Thank you," was all she said.

Lucy kissed his cheek and then continued packing. Four hours later, she was ready to go. She loaded all her things up in a cab and she was off to Baker Street with her cousin.

The second they arrived, Sherlock about had a fit. "John, I sent you to get milk and you bring home a child," he said unsatisfactory.

"Sherlock! Behave yourself. This is my cousin Lucy. She'll be staying downstairs for a bit," John said. Sherlock didn't seem to care. He just started plucking at his violin.

Lucy studied him and bore into his believed non-existent soul. She knew that he had to be something different than the average man. She found him quite attractive with his tall, lanky body and his brunette curls. His eyes seemed to pierce into her like he was looking into her entire life. After staring at him for a few moments, John cleared his throat and she was gone from the trance. "I'll just move in then," she said and headed down to the basement with John and Mrs. Hudson. Sherlock never came by to help out with the moving in. Not much for a first impression.

A/N: That's the first part. I hope to have the second part up soon :D
