(AN: Hello everyone and welcome to my first Sherlock story! I am going to do my best to keep this as close to the show as I can and keep the characters as realistic as possible, but I am not British nor an autism expert. If you have any suggestions on how to make this sound more British, flesh out my OC, or make the charchters more cannon please let me know! Constructive criticism is appreciated and welcomed!)

It was a quiet day for Greg Lestrade. His children where staying with his ex-wife and her new boyfriend for the week, so the house was empty. His plans for the day was to watch a little football then get some take away, nothing terribly exciting but a good enough way to spend a day. Just as he was settling in to watch the match there was a light knocking on his front door. "Hold on!" he shouted to the door, standing up. The knocking was continuous and steady, it also was painfully annoying. By the time he got to the door he was rather cross with the person standing on the other side.
"Hullo?" he said opening the door, then his jaw dropped slowly.
Staring into his house was a scrawny,pale, woman, about 30, with blonde hair stretching down past her shoulder blades with the same brown eyes as him. It was his younger sister Violet and much to Greg's confusion she was laden with a black duffel bag, twice as wide as she was, and a tan suitcase.
"Hello, may I come in?" his sister said in her high voice engaging him in one of her trademark hugs, her face pressed against his with one hand on the back of his head and the other wrapped around his shoulder.
"Umm yeah, of course." he said still puzzled stepping aside letting her walk in after reciprocating her hug in a more traditional manner "What are you doing here?"
"I wanted to visit you, Dylan, and Paige." she said still looking around.
"Well, hate to disappoint you Vi but it's just me, Paige and Dylan are with Catherine this week."
"Oh, that's alright." she said calmly.
He laughed a bit as he shut the door and his sister turned and looked at him tilting her head.
"What's funny?" she asked
"It's nothing Vi, I'm just surprised is all, I didn't know you were coming." he said
"Should I have called?" she asked unsure, squinting in concentration.
"Yeah, that would've been a bit better." he said.
"Oh," she said making a surprised face, her eyebrows raising "I'm sorry, I will be going then." she then began walking towards the door.
"No, no, Violet it's fine, I'm really glad to see you, I just didn't know you were coming to see me is all." he said stepping in her way, he then paused in thought for a moment. "How did you get here any way."
His sister and parents lived two hours away and Violet did not know how to drive. Her income was fairly small and usually went into her savings account,so she most likely wouldn't have bought a train ticket, and his parents would have told him she was coming if they had bought her a train ticket. Violet smiled proudly.
"I've been selling my paintings and I saved enough for a train ticket, so I decided to come and visit." she said with exuberance, then she grinned even wider and continued " I didn't have any fits on the train at all, only a bit anxious."
"That's lovely Vi, do Mum and Dad know you're here?" he said.
"I left a note on the fridge." she said nodding.
"Yes, but did you tell them you were coming to see me?" he asked slower.
"I left them a note on the fridge." she repeated sternly.
"I'll just give them a ring to see if they know you're here." He said pulling out his mobile then he gestured to his living room "The Liverpool versus Manchester United game is on if you want to watch it."
Violet grimaced at him.
"Too much red running around, I'll just put away my things." she said walking upstairs.
"Alright, how long do you plan on staying." he called after her.
"A week." she said walking up the stairs.
"Alright." He called up to her and dialed his parents phone number.
His mother answered out of breath.
"Hullo?" she said, sounding frantic.
"Hi Mum, it's Greg." he said.
"Oh hello dear, I'd love to chat but I'm a tad busy, We can't find..." she started but Greg cut in.
"You can't find Violet?" he said calmly.
"Oh my goodness, yes, have you heard from her, is she alright?" she said frantically.
"She's fine mum, she decided she wanted to come spend a week with me and the kids, she's upstairs putting away her things." he said trying to soothe her.
"Oh my God," his mother sighed "Thank you, we were so worried."
"Not a problem, but next time check the fridge and see if she left you a note." he said leaning against a wall.
"Oh there is a note." his mother said chuckling.
Greg took advantage of his mother not being in the room to roll his eyes at her. It had been established for many years in that house if you were leaving that you left a note on the fridge if there was no one to say goodbye to. How he seemed to be the only one who realized Violet still adhered to this he could not understand.
" Alright, thank you dear, your father and I will come and pick her up tomorrow morning." his mother said.
"No Mum, I don't mind her staying for the week." he said.
"Oh," his mother said slowly "If you are sure you are alright with it."
"I am Mum." he said calmly, getting a bit annoyed.
"Alright could you put her on? I would like to talk to her." she said.
"Mum, she's 32 years old she's allowed to make her own decisions." he said exasperated.
"I know love, you know Violet better than anyone but you have to realize that she isn't ready to be on her own." his mother said.
"Yeah, I suppose, listen Mum I have to go,tell Dad I said hi, I love you and I'll see you soon." he said gazing up at the ceiling.
"I love you too dear, tell your sister we love her." she said.
"I will." he said hanging up.
He sighed and wandered over to his couch, sinking into the cushion. His mother was right about Violet and he hated it. Violet always had a fragile mental state and despite having a more realistic view on her abilities and seeing her progress as she got older, Greg had to admit that even he couldn't see anything in the immediate future where she could live on her own. The one part of what his mother had said that Greg was alright with was his knowing her better than anyone. Someone had to at least have a marginal understanding of Violet and he wouldn't trade the relationship he had with her for the world. But it didn't mean that this situation didn't make him want a cigarette.
