A/N: Right then, I have a request now, that I decided to make a multi-chapter instead of putting it in The Mollcroft Files. In a PM from Empire of Fiction, there was this adorable beauty:

Could I possibly request a Molly/Mycroft fic in a AU where Molly has a young child that accidentally bumps into Mycroft when he goes to the morgue to go check on Sherlock and the young child decides to do whatever they can to make sure Molly and Mycroft end up together. I've had the idea for a while now but don't really know where to start in terms of writing it. I was wondering if you could have any luck with the idea :)

Much fluff ahead! This is gonna be so fun!

Mycroft was grumbling as he strode down to the morgue that one fateful day. According to his surveillance, Sherlock had been spending an unusual amount of time in the morgue lately. And to make matters worse, he had to leave an important meeting to make sure Sherlock was okay. He was so busy in his own thoughts that he didn't notice the 5-year-old sprinting at him until it was too late. The boy collided with Mycroft's legs and both of them wound up sprawled on the floor. Mycroft cursed under his breath reflexively, then checked to make sure the child didn't hear. Thankfully, he seemed not to. The child sat up, rubbing his head. "Sorry mister!"

Mycroft started to get up and dust himself off. "What are you doing in a morgue? You seem a little young to be here by yourself. Where's your parents?"

The boy shrugged. "Don't know where my dad is. But my mum is working, and there wasn't any school today, so she let me come in to see her job."

Mycroft huffed. "Well, why aren't you with her, then?"

The boy stared at him, not responding. Mycroft felt his impatience rising. "Look, I'm heading to the morgue now. What do you say I walk you back there?"

The boy smiled and nodded. Mycroft took the time they were walking back to get a good look at him. His hair could use a good cut, and was somewhere between brown and blonde, but couldn't be called either way. His eyes were green, and taking in everything around him, including Mycroft. When they entered the morgue, Mycroft saw Sherlock doing an experiment with a jar of eyeballs (he didn't want to know,) and the pathologist…Molly, her name was, looking around frantically. The boy ran up to her and she looked down, relieved. "Matthew, where have you been?!"

Matthew didn't seem to notice her panicked tone and said, "I went out to go to the vending machine and get a snack, but I accidentally ran into this guy, and I don't know his name, but he was coming here for some reason, I don't know why but he looks really important, so it must be important too, and-"

Molly put a hand over his mouth and said, "Don't you ever run off on me again, all right? Next time you want a snack, ask me first. I didn't know where you were, what would have happened if you got really hurt?" She looked up at Mycroft. "Thank you so much, Mr. Holmes, for bringing him back."

Sherlock looked up at that. "Mycroft, what are you doing here?"

Mycroft looked over to him irritably. "I came here because of you. You've been here an awful lot lately. May I ask why?"

"No."

Mycroft scowled. "Sherlock, it has come to the attention of certain people who could ban you from coming here that you make frequent comings and goings. In order to keep them off your back, I need to know why you're coming here."

Sherlock shrugged. "Too bad."

Mycroft looked like he might crush his umbrella's handle in his grip. Molly cut in before there would be a shouting match. "Sherlock has been trying to recreate human body parts without using any that have been already made. In order to do that he has to learn everything he can about them."

Mycroft looked over at her and nodded. "Thank you, Ms. Hooper."

Matthew looked between Molly and Mycroft, realizing that they seemed a lot alike. That decided, he made a plan: he knew Molly was sad and wanted a boyfriend, no matter what she did to try and convince him otherwise, and maybe she and this Mr. Holmes guy could work, since they both seemed protective and like they were lonely, even if they didn't seem to know it.

That settles it, he decided. I'm going to get them together whatever it takes!
