It's been a couple of weeks since Sherlock and John had been raising Rosie; together. They had a mutual agreement of being her father's and anybody could argue if they were a couple. John, of course, would continue to claim he wasn't gay. Greg and Mycroft had a bet and every time they visited the Baker Street Boys, if they caught them in some sort of intimate moment, Mycroft would slip a 20 into Greg's pocket. For example, Greg had found a particular murder case and needed to tell Sherlock after getting a lot of text messages from him complaining he was bored. But that wasn't what he saw when he opened the door to 221B Baker Street. John was holding Rosie by her arms and was having her walk towards Sherlock who was smiling and cooing at her. Greg nearly dropped his coffee in awe as she grinned at Sherlock and fell into his arms. Then, oh but then, Sherlock LAUGHED. He. Laughed. John was grinning at the two of them and the three all shared a hug as if they were a family.

Greg decided that was the time to make his appearance known.

Clearing his throat he said. "Well isn't this a sight."

John and Sherlock looked up and even little Rosie looked at him and began to cry. Sherlock' face contorted into anger and annoyance.

"Are you serious? You should've knocked on the door and not have affected Rosie's concentration." Sherlock growled.

Greg raised an eyebrow and laughed. "Oh my apologies I should've known she would be awake." Sarcasm dripping out of his comment.

Sherlock rolled his eyes and turned to speak softly to John. "Why don't you go put her down and I'll rock her to sleep? Rosie, daddy will be there in a moment alright?"

Rosie sniffled and gurgled at him as John chuckled and nodded at Greg before going to put her down.

Sherlock turned stiffly on his feet towards the fellow police officer. "What do you want."

"I have a murder case and-"

"Not interested." Sherlock said as he fell down on his chair and picked up a newspaper. "It's probably boring and most likely the wife was the one who hid the children and threw the husband's body into the river. So go away, I have to make sure Rosie gets her sleep or John will have my head."

Greg opened his mouth and shut it before narrowing his eyes. "For god's sake Sherlock what the bloody hell has happened to you?"

At first Sherlock was silent but he turned his steely eyes towards Greg. "Emotion."

That was just one of Greg's examples of how he knew deep down John and Sherlock had a relationship that wasn't just 'best friend' material... but he wasn't complaining cause he got $60 that week. Sure, they would act as they normally would around colleagues and during cases but as soon as they felt nobody looked there would be secret smiles and comments about Rosie.

Today, Rosie had to go to daycare because of the fact Mrs. Hudson needed to visit her sick friend and thus couldn't go and take care of Rosie as John and Sherlock went to solve a case. The two sat in the cab, Rosie on both of their laps because they sat close together. Getting out, Sherlock carefully lifted Rosie and carried her over to the door of the daycare where Susan Hopkins was smiling at them. She had curly brunette hair, blue gray eyes, and had freckles across her nose. The two Baker Street Boys entered the building and saw other mother's dropping their children off. Several of them stared either because they thought they were a gay couple or they recognized Sherlock.

"So how may I help you boys?" Susan asked with a grin.

Sherlock didn't return the grin. "Yes we need for the daycare to look after Rosie while we go and solve a murder where a woman, I think, was brutally-"

"Sherlock." John warned.

Sherlock looked over and saw John with the look of 'say one more thing and I will personally make you a murder victim.' "Sorry my apologies. This is Rosie Watson."

Susan nodded, slightly disturbed. "And the parents names please."

"Sherlock and John Watson." Sherlock responded instantly.

John looked at him with a look of confusion, admiration, and a tad of annoyance. Susan didn't seem bothered and instead took Rosie out of her arms.

"Perfect! Just so you know the daycare closes at 4 so please be here to pick her up." Susan said as she nodded at the men and left the room.

Sherlock and John turned to each other and gave small smiles before leaving the daycare, oblivious to the stares of the other mother's, all sharing knowing looks. Sherlock and John left the daycare in a hurry and gave the address to the cab driver. The two boys arrived at the scene and looked down at the woman. It was a young girl, 22 by the looks of her crinkles around her eyes with pale skin, ginger hair and green eyes. John scrunched his face up in pure sadness as Sherlock just walked cautiously around the sight.

"Poor kid." Greg whispered as he appeared next to John who looked like he would throw up.

"Oh my god I know her." John gasped as he knelt down and examined her face.

Sherlock frowned at John. "How did you know her?"

John frowned and looked at Sherlock. "Remember when we went out to dinner, just the two of us, and Mrs. Hudson was out playing poker so we had to find somebody really fast to watch over Rosie?"

Sherlock nodded along. "Yes I do recall because you got so drunk off that red wine you kept begging me to kis-"

"KILL." John shouted, scaring Greg and Mycroft who had appeared at the scene. "Kill, yes when I was begging you to kill that woman who kept shouting in the restaurant."

Sherlock frowned. "Well you were trying to kill me with your mout-"

"MOUNTAIN- you know whatever shut up Sherlock." John groaned as he saw Mycroft slowly hand Greg a $20 bill. "The point is that Sherlock and I hired this woman to be our babysitter. Her name is Kat Grinly. When we dropped Rosie off she seemed concerned about having a child at her apartment and was incredibly nervous but I was too worried about the reservations I didn't pay attention to it." John said as he stared at her face. "When we picked Rosie up we noticed that Kat was nervously biting her nails and all the lights were on in her house and she was startled when the we rang the doorbell. Sherlock started to deduce her and scared the poor woman even more and I politely grabbed Sherlock and Rosie and left."

Sherlock turned accusingly towards John with a look of disbelief. "Politely? You nearly ripped my ear off pulling me out of the woman's home. All I said was I thought she had a stalker due to her closed blinds, triple locked doors, and opened rooms to get up and down the stairs quickly. She clearly was in a state of distress. No wonder she was found dead."

John elbowed Sherlock in the ribs and shook his head. "Point is this is incredibly worrying... Oh God Rosie could've been there when it happened. Alright we will take some DNA samples, photos, anything else. This case has to be found. For some reason I find it too worrying due to the fact that Rosie was just with a woman who was murdered."

Greg just shrugged and nodded. "Well yeah that's why we called you and Sherlock, or were we interrupting you two having a romantic interaction?"

John's face turned red as Sherlock just shrugged. "Well we are apparently married, or so says the daycare John and I dropped Rosie off at. Speaking of, John we have parent time on Thursday so don't make plans."

"I had a date-"

"Cancel it, I'm not going to sing nursery rhymes to a bunch of dumb, small children without you." Sherlock said with distaste.

Mycroft frowned and gave Greg another $20. "Can you two knock it off for at least until you get home so I don't continue giving out my money as if Greg is a stripper?"

Greg blushed deeply and cleared his throat. "Um anyways, we asked some witnesses or friends of hers and they admit she would always ask people to walk her home after working her shift from the daycare-"

"Wait." John spoke up. "She works at the daycare too?"

Greg nodded and looked down at her. "What I don't understand is how she was poisoned. There are no needle marks on her skin, no residue of a pill, we checked for both tablet form and liquid."

Sherlock picked up the cold woman's hand and looked at her fingers. Pink was visible under her fingernails and under the skin of her finger. He scanned her body and entered his mind palace, looking at possible ways of dying. There was glass around her body from crashing through her window but that was on the bottom floor so she would not have died from that. The glass was cleaned but fragile so if she had passed out and died, her body weight alone would've crushed the window to pieces, not the glass so she must've been poisoned before. Sherlock quickly jumped up and grabbed John's arm as they headed to the entrance of her home. The first thing Sherlock saw was that there wasn't much struggle. The doorknob was turned in a rush as though she was fearful walking home from walk alone(there were no footprints in her garage that would say another person was there) but when him and John had opened the door to let themselves in, it reset the door therefore throwing off any source of security the woman planned. Sherlock slowly crept in and examined the scene. The window was just across the room where she fell out. Quickly moving, he ran to the window and examined the outer layer of the window:

Cleaned

Cleaned

Cleaned

Dirty.

Aha. Sherlock smirked to himself as John, Greg, and Mycroft shared a confused look.

Turning swiftly, Sherlock and pointed at the three of them.

"Your murderer is a parent at the daycare. The woman was unhappy about the care her child received from this particular care giver and she lashed out by dropping off a toy that was laced with a poison I'm not sure which one have Anderson find it, maybe if we're lucky he will get infected because of his low IQ. Point of the matter is you must interrogate every parent there and make sure no child goes to it." Sherlock said as he slowly grabbed John's arm and looped it with him. "Now if you don't mind us, we have to save our daughter from a possible murderer."

"Wait what?!" John shrieked and completely ran, dragging Sherlock with him. They didn't see Mycroft frown and give another $20 to Greg.

"Wait hold on, you KNEW it was the daycare we dropped Rosie off at? And you didn't think that, oh, I don't know, maybe it isn't a goOD FUCKING IDEA TO PUT HER WHERE THERES A POISON SCARE?" John screamed at Sherlock who was calmly sitting in his chair.

"John lower your voice or you're gonna wake up Rosie." Sherlock said taking a sip of tea that Mrs. Hudson brought up.

John arched his eyebrows in a bitchy matter and laughed bitterly. "Are.. are you, joking right now? Do you honestly think right now is appropriate for that? Our- Rosie could've been killed or poisoned!"

Sherlock rolled his eyes and walked calmly over to John. "John, listen to me, the poison isn't meant to harm the children but only the caregivers. The child takes the poison after playing with the toys at the daycare because the murderer laced it with it since all kids play with the toys with their mouths and hand and then gives it to the parents. This virus was specifically motified in order to not harm any of the children so our murderer has a soft spot. He's just trying to destroy any parents. The murderer obviously wants to own these children and raise them like soldiers. It's the worst kind to be completely honest cause these kids are so stupid and small they can't do anything but that's my opinion... no offense Rosie."

Rosie gurgled at him and John scowled. "Whatever. Listen we have the sing along today and you're going as punishment for putting her in harms way."

Sherlock just shrugged and put a jacket on. "It wasn't my fault John, if we didn't drop her off she would see a woman dead and you wouldn't want that would you?"

John seemed to have an internal fight with himself but gave up as he picked up Rosie. "Just, we will discuss the case when we get home but for now we are going to sing some nursery songs with Rosie."

Sherlock sniffed in disdain and went down the stairs bumping into mrs. Hudson.

Mrs. Hudson looked at the three with a knowing smile. "Well aren't you all a sight for sore eyes! Where are you off to now?"

"Singing, apparently." Sherlock said with a sour look. "I don't know why we can't teach them the violin."

John rolled his eyes and secured Rosie on his hip. "Oh yes Sherlock, of COURSE, kids at Rosie's age should for sure be okay to play violin!"

"Thank you John for agreeing." Sherlock said with a smile and left the apartment with a glaring John following him and a smirking Mrs. Hudson watching the boys bicker.

They got to the sing along and John felt out of place. He watched as only mothers entered the buildings with their children.

"Sherlock are you sure-"

"Yes I'm sure just keep walking." Sherlock said as he wrapped his coat around himself tighter.

John frowned and snuggled Rosie more against his shoulder as he held onto the baby bag with the other hand. They entered and saw possibly 24 other mothers all talking amongst each other. They of course stated slightly at the two men as they sat as far away as they could.

"Sherlock hold Rosie for a minute?" John said as he started to get the baby bag situated.

Sherlock huffed and picked her up, immediately smiling and tickling her stomach. John was in the middle of fixing Rosie's bottle when a woman cleared her throat. Looking up, John locked eyes and oddly recognized her but didn't say anything as he stood up and shook her head.

"Hello I'm Kate Winsley, head of the parent sing along!"

Sherlock rolled his eyes. "It's not 'parent' sing along cause it was originally mommy sing along but once a male couple comes in you changed it to parent. I applaud your effort though."

The woman opens her mouth and shuts it as John groans out loud and forces a smile. "Hi Kate I'm John and this is Sherlock. This little angel here is our Rosie."

Kate smiled uneasily and shook Rosie's hand. "Well we are pleased to have you here! You can go and talk with the other parents and we will start the activities soon!"

John smiled at her in thanks and looked at Sherlock. "You, sir, need to calm down."

Sherlock in response just huffed and followed John to another mother who was busy play fighting with her son. "Hello ma'am."

The woman looked up between the two of them with a confused smile. "Oh hello! You're the Baker Street Boys correct? That's what you're called these days at least. I'm Joan! This is little Markus, he's a sweetheart!"

John smiled. "He's a cutie! I'm John and this is Sherlock as you know."

Joan laughed. "That's great! Everybody always knew the two of you were a couple! And now even raising a daughter, you two moved fast didn't ya?"

John blushed slightly and looked at Sherlock who was busy throwing Rosie in the air and catching her with a small smile.

John turned back to Joan and scratched the back of his neck. "Well, uh, we aren't.. um we aren't really together together but we are together and, uh, we-we are just raising Rosie platonically."

Joan just stared at him before bursting into laughter. "Oh John Holmes you are a funny man indeed! Ha! Oh well best to you and your husband! As well as little Rosie too!"

John sighed in defeat and just smiled awkwardly. "Yes thank you."

The activities started pretty fast and the next step was team building activities between different parents. Since sherlock and John came together, they automatically were partners.

"Okay ladies, and men, our next activity is piano play!" Joan said clapping her hands and jumping.

Sherlock scrunched his face up and leaned to John. "I'm pretty sure she's a murderer."

"That's called being overly happy, Sherlock." John whispered back.

Joan passed around the piano and Sherlock took extra time grabbing the toy piano from her hands in order to deduce her. Luckily, John took the toy from both of them earning a scowl from Sherlock. The mothers were letting the kids bang annoyingly against the piano which made Sherlock twitch with a tad bit of anger as John and Sherlock took turns playing the piano for Rosie because she had no interest in doing it herself.

"Come on Rosie isn't this fun?" John said as he tapped along the piano.

Rosie just stared at him with a seemingly annoyed glance and surprisingly enough, Sherlock wore the exact same expression.

"John let me try." Sherlock said, making grabby hands at the piano until John rolled his eyes and handed it over. "This, my dear Rosie, is how you REALLY play piano."

Suddenly Sherlock was holding two sticks in his hands and was releasing a very high pitched version of Mozart. The other mothers stopped their children and stared in amazement as Sherlock rhythmically tapped against the piano keys. John's mouth fell down halfway through and he stared at Sherlock's expression and the movement of his fingers. As he continued playing, John's mind wandered into something more... deep. He watched his hands go in beat with the keys, how his knuckles were clenched around the stick and showed his veins against the skin, how his long fingers gracefully moved against the piano. Traveling his eyes up, he looked at Sherlock's face. His lips were in a pout of concentration, eyebrows burrowed down in a state of amusement and play, and when John looked at his eyes in wonderment, Sherlock's flew to his and they held contact for what seemed like hours but it was merely seconds. Suddenly there was no calming music in the background but rather of applause and Sherlock's steely gaze locked onto John's glazed one.

"Well well well! That was absolutely incredible! Everybody let's give a loud applause for the Holmes family!" Joan said happily.

John finally broke Sherlock's gaze and smiled at everyone. Little did anybody know, that in John's head there was a constant band of the word 'shit' circling around his head, as his emotions for Sherlock escalated.
