Bit of a short one here, sorry! But I felt the need to get a chapter out there already. The next chapter will be longer, I promise! Anyways, thanks for reading! Credit to princeofthefallingangels who wrote for John in this chapter x
John woke up first walking down to Sherlock's area looking around for him. Shrugging not seeing him, he decided to let him sleep since it had been five days since he slept. He remembered Sherlock going out last night but didn't hear him return so just to make sure he was there he walked over the door and opened it quietly looking in. He smiled lightly to see Sherlock so peaceful as he slept in his clothing still. John was about to look away when he saw someone else in there. He couldn't make it out so he stopped in shock that someone was in the same bed as Sherlock. He swallowed quickly at the awkward feeling he just got and turned and close the door quietly.
Sherlock woke up to find Alice still sleeping. He silently got up and grabbed his phone to check the time. 8:23. John would be up already. Sherlock went down to the living room of the flat where he knew John would be, and upon seeing him he could see that John had walked into his room to see if he was there and found Alice as well. "John we are taking care of my cousin now. She will call me 'Uncle' but don't be confused, she is my cousin." He said, right when John saw him walk in, to avoid confusion. "Her mother died, who was my Aunt Emma's daughter, her husband killed her mother and tried to kill their daughter. I saved her and I won't just bring her back to her father to be killed or anyone else because then she could be easily gotten to. Her name is Alice. She's 4 years old, almost 5. I hope you understand."
"What about Mycroft?" John tried to take it all in at once, "Why can't Mycroft take her?"
Sherlock shook his head. "And leave her practically smothered in care and with 'do this, do that, here's your clothes, take a bath' as I was as a child?" Sherlock made a face as if disgusted, and genuinely, he was. Sherlock just knew Mycroft would take care of her like how he took care him. "I won't have it. We'll take care of her, John. No problems. But we will inform Mycroft, later though. I need some coffee." Sherlock said, then turned to the kitchen and began making a cup.
"Sherlock, we don't have the things to take care of a child." John's voice rose, "I love kids but I mean you-" he laughed slightly, "You can barely take care of yourself and since when do you like kids?!"
Sherlock paused. "It's only logical? We can get the things. John, she needs protection, we can offer that. And yes I can take care of myself. I did live alone before we met. Please. It's the stupid and annoying kids I don't like. She's neither stupid or annoying. Shes interesting." Sherlock continued making his coffee, noticing he had stopped.
"Sherlock you do know your brother was taking care of you right? But if you want to take care of her then you will." John picked up the newspaper looking at it then sighing out, "You had better call Lestrade. He's on her case looking for her. It's already in the paper."
Sherlock smiled to himself and finished making his coffee. "Playing single mother will keep me from being bored I suppose." He said, sitting in his chair. He took a sip of his coffee and skimmed the back of Johns newspaper.
