Dr John Watson stepped into to the living room and froze at the sight of his partner holding a blanket wrapped, suspiciously baby-shaped thing in his arms.
"Ah Sherlock what are you doing?"
"I would think it obvious John, holding a baby."
"Yes I see that," responded the doctor carefully, "but what are you doing with it?"
"The imbeciles failed to find it when they cleared the crime scene, so I brought him home."
"You can't just take a baby Sherlock, it belongs to someone else."
"No he doesn't - he was abandoned and no one has claimed him."
John rubbed his forehead where he could feel a monster headache incoming. "What are you planning to do?"
"Why to keep it of course."
John sucked in a breath. "He's not an experiment that you can just give back when you're done you know."
"Of course. What do you take me for?"
He ignored the question. "Do you even know how to look after a child?"
"That's what I have you for."
"I'm sorry what?"
"Here, you're going down as a guardian too."
John looked blankly at the page thrust in front of him.
Guardian: Sherlock Holmes
Guardian: John Watson
"What would we even call him?" he heard himself asking.
"Hamish Watson-Holmes. Must you really question the obvious?"
John groaned.
Now people were really going to talk.
And so as parents of young Hamish, the doctor and the detective found themselves growing closer than ever, until one day it became something more.
