I feel like I'm posting up to many stories, I hope they don't come and bit me in the arse later. My mom actually gave me the idea to write this story, she's a huuuge Sherlolly shipper and she thought it would be interesting to put Molly and Sherlock in this situation. I'm sorry for killing John and Mary, I love them so much and I didn't want to do it, but for the sake of the plot I had to kill them. I'm a murderer! Don't hate me!

If you recognize them I don't own them, obviously.

Feel free to review! Enjoy chapter one!

Molly Hooper let out a sleepy groan as her phone rang loudly, she slowly opened her eyes after her fail attempt to grab her mobile from the night stand. She squinted at the bright light as she read the familiar number of DI Lestrade flash up on the screen she quickly wondered what he wanted this time, perhaps it was another late night case, those had occurred a lot lately, she'd have to drag her arse out of her warm bed and go all the way to Bart's simply because Sherlock couldn't wait until morning. Molly let out a tired sigh and answered her mobile; she placed the cold device on against her warm cheek and spoke.

"Yes? What is it?" she croaked tiredly.

"Hello? Molly? It's Greg. Greg Lestrade, sorry to call you at such an inconvenient hour I'm sure you're tired of me doing this..."

Molly mentally blocked him out , he was a nice man a bit chatty especially when she was tired he always had a habit of getting side tracked when she just wanted him to get to the point so she could get hang up.

"Molly are you still there?"

"Uh, yes. I'm sorry." she murmured.

"Did you hear what I said?"

Molly remained quiet but she could hear him on the other end, he let out a sigh before speaking.

"Mary and John got in a car accident..." he said.

"What!?"

Molly quickly sat up on the bed she threw the duvet off her body and stood up, "Are they alright!? What happened!?"

"Molly... I think you should come to Bart's..." he sounded quieter... sadder, a lump formed in Molly's throat and she quickly hurried to change.

"I'll be there soon."

Eight Months Earlier

"Sherlock? Are you here?" called the familiar voice of John Watson.

Sherlock laid on the couch in his very common, very familiar "thinking position" his fingers twitched lightly as he heard John's voice by the door, his soft footsteps began making his way further inside the flat until they stopped a few centimeters away from him. Sherlock opened one eye to look up at the sandy-haired man.

"Of course I'm here, John. It's not like I have a case or anything." he said rather bitterly.

John chuckled lightly before turning on his heel and walking to the kitchen, "Have you eaten?" he called out.

"Just tell me what you want." said Sherlock as he stood up.

The consulting detective stood up and pulled up the sleeve of his blue robe before making his way to his friend. John stared at him as he made his way towards him and smiled,

"Why do you think I'm here for something? Can't I just be a friend visiting another friend?"

John walked into the kitchen and began busying himself with preparing them tea.

"Obviously you're not here for a friendly visit." stated Sherlock.

"What makes you say that?" replied the doctor.

Sherlock listened to the clatter of dishes in the kitchen and plopped himself down in his chair, "You've been rather busy with the baby. It's been two months now? Since she was born and you've hardly come to pay me a visit so clearly you're here for something else."

John made his way to the living room with two mugs of tea and handed one to Sherlock before sitting down in his old chair, "Alright, you caught me." he said before taking a sip of his tea, "I'm actually here to ask you something."

Sherlock rolled his eyes as he took a swallow of his tea, "What is it, John?" Sherlock observed him now, he was nervous, but why? Clearly whatever he wanted to ask him was important. He was trying to find the right way to tell him, concluded Sherlock.

"Well, Mary and I... We've both discussed this for weeks now and..."

"John, please do hurry this up." said Sherlock with a hint of irritation.

"We've come to an agreement that we want you to be Charlotte's guardian."

Sherlock made a face before speaking, "What? Why me? I am hardly capable of taking care of a child, John. I am not a suitable candidate to be someone's guardian." he scoffed.

"We know that's why we made Molly, Charlie's other guardian."

"Molly?"

"Yes Sherlock, you know Molly." he sighed.

"Of course I know her... Why her?"

John took a sip of his tea and rubbed the bridge of his nose, "You know she's known Mary since they were both children. They're like sisters and Mary trusts her. Plus, Mary's mum is sick so we can't have her as a guardian and Harry already refused so the only other people we trust with Charlie are you and Molly"

Sherlock rolled his eyes and leaned back on his chair, "What would I have to do?" he asked curiously.

"Nothing, we're just doing this as a precaution in case... In case something ever happened to either Mary or me."

"Highly unlikely." muttered Sherlock.

"I do need you to sign something, though."

With that John hopped out of his chair and set the mug down, he hurried to the kitchen table and grabbed a manila folder and hurried back to Sherlock's side.

"I need you to sign this form saying you agree to be Charlie's guardian."

Sherlock snatched the folder from his grasp and scanned it before opening it, he read through the print stating that if by reason Mary or John could no longer care for their daughter then Sherlock... and Molly would take over. Sherlock looked down at the bottom of the page to see Molly's signature already on it.

"Molly already agreed?" he said without looking up.

"Uh, yes. She came over for tea yesterday and we talked to her about it."

Sherlock nodded before meeting John's eyes, "Since it's only a precaution and there's a slim chance that anything would ever happen to you or Mary, I agree to be Charlotte's guardian."

"You will?"

"Now give me a pen before I change my mind."

John quickly scrambled out of his seat and went to look for a pen, after rummaging around the flat he finally found one and handed it to Sherlock. The dark-haired man let out a huff of air before signing his name under Molly's.

"There you go." he said as he handed John the folder.

The sandy-haired man gave him a big smile, "You don't know how much this mean to us, Sherlock. Thank you."

"There's no need to thank me. It's only a precaution after all."

"Only a precaution." repeated John.

Present

Molly hurried down the familiar corridors of St. Bart's hospital she spotted Lestrade further down clutching a crying Charlotte in his arms. She could see his face relax as soon as she spotted her.

"Molly, I'm so glad you're here." he sighed in relief.

Molly stretched out her arms to take the crying baby from him, she whispered soft words to the crying girl and slowly bounced her up and down until her tears reduced, she kissed the top of the young girl's head before looking up at Lestrade with sad eyes.

"What happened?"

Greg rubbed his eyes tiredly before speaking, "They were driving back from Cardiff when a...drunk driver hit them. All three of them were in the car, luckily Charlie here made it out safely."

Molly took a closer look at Charlotte, there was a few scratch and bruises but nothing that wouldn't heal with time. Molly licked her lips nervously, she was afraid to ask the next question.

"What about... John and Mary?"

Greg gave her a sad expression and shook his head, "They... They didn't make it."

Molly couldn't believe it, she handed Charlotte over to Lestrade, for fear that she might drop her, the pathologist sat down and pressed her hands into her face. She took deep breaths trying to calm herself down, but it wasn't doing her much good tears pooled at her eyes and began running down her cheek. She couldn't believe it, two of the most wonderful people gone, gone forever. Greg patted her shoulder gently and sat down beside her; Charlotte began fussing and suddenly began to cry. This caused Molly to look up at the tiny girl and take her from his arms,

"Poor Charlie." she whispered, she began patting her back lightly trying to calm her down when she finally did she nuzzled herself on the crook of Molly's neck and fell asleep.

"No child should go without their parents." said Greg.

"What are we going to do?" she asked him curiously.

"Well Charlie will have to be handed over to CPS."

"What!? Why?"

"Only until we figure out who she will be going to."

"Molly and I are her legal guardians." said a baritone voice suddenly.

Both Molly and Lestrade looked up to see Sherlock; he wasn't looking at them rather at a sleeping Charlotte in Molly's arms.

"What?" said Lestrade suddenly, "You!? Charlotte's guardian?"

"Yes, John and Mary entrusted us to care for their daughter if anything were to happen to them. Isn't that right Molly?"

Molly nodded absent mindedly before opening her mouth to speak, "Y-Yes, Sherlock is right. We are Charlie's guardians I'm sure you can call some people if you need proper documentations." she told him.

"I'm sure you have a few phone calls to make, Lestrade. For now Molly and I will be taking Charlotte with us. Come along, Molly."

"Where are we going?"

"Molly don't ask stupid questions." He snapped.

Molly opened her mouth but quickly clamped it shut and stood up, there was no point in arguing with Sherlock especially right now... Molly took a tighter hold of Charlotte and looked at Lestrade, he was on his phone now talking rapidly to someone on the other end. She turned to face Sherlock but he was already striding down the hall.
