My name is John Hamish Watson. I live in flat 221B, off the corner of Baker Street, with my flat mate, best friend, and dare I say it, boyfriend, Sherlock Holmes. A few years ago, Sherlock and I adopted a stray, right off the sidewalk in front of our building. Her name is Sabina. You may very well ask if she is a cat or dog or some other typical pet. Sabina is none of those. She is neither an ordinary animal, nor an exotic animal. She's not an animal at all. She's human, and is one of the best and worst things that has ever happened to me at the same time.

It would probably be best to start at the very place I should, the beginning.

A Few Years Ago~

"I don't see why you wouldn't want a pet John. I would almost be like raising a child."

I groaned and pinched the bridge of my nose. This is the third time that Sherlock has asked me about getting a pet. Though I must admit this is the first I'm hearing about an impromptu child.

You see, Sherlock and I have been, well, together for about five months now. And not together as in always with one another (though we always are), I mean together together. As in boyfriends, together. And while I do care very dearly for this man, though the bloody git made me wait for three years before telling me he was alive, I was getting a bit tired of this pet talk.

"Sherlock, a pet is a big responsibility, and we're always running around solving cases, leaving for days on end. That's no good for a pet." I explained.

"But Mrs. Hudson-"

"No, Sherlock. If you want an animal that badly, you have to take care of it all the time. No Mrs. Hudson stepping in for you." I cut him off.

Sherlock went quiet. I snuck a quick peek at his face and what I saw surprised me. Instead of being stoic like I thought they would have, his lips formed a small frown. A pout almost. I hurriedly looked away, knowing that I would give in if I didn't. Before I could change the topic, Sherlock did for me.

"John, what is that?"

I looked up, immediately knowing what he was talking about. Up ahead, poking her head out of the alley way between the sandwich shop and the next building was a dirty blond girl. She looked to be about fifteen or sixteen. Old enough to be out on her own, but young enough to still ask why she was. Then I realized why Sherlock asked about it.

She was looking straight at us, grinning to herself. Having to deal with several of these before, I at once recognized what she was and the severity of the situation.

"That's a fan girl, Sherlock. A girl, who likes a certain couple a lot, almost obsesses over them." I answered. "Dangerous for the two of us."

"This little girl?" He asked, in slight amusement.

I just nodded, and watch the girl gather the courage to approach us. She was slightly shorter than I was, about a head shorter that Sherlock. Her green eyes shone with a glint of mischief.

"Hello." She greeted us, obviously American, no accent.

"Uhm, hi." I greeted back.

"Hello. I'm Sherlock Holmes and this is my," Sherlock hesitated and grinned and me momentarily. "Partner, John Watson."

"My name's Sabina." She told us and offered her hand. "Pleasure to meet you."

Knowing Sherlock, I grabbed her hand in his stead. "Pleasure's ours."

"So what is a young girl like you doing around her?" Sherlock's eyes glinted in excitement. "Do you have a case for us?"

Sabina shook her head. "Nope, sorry. I'm just looking for a place to stay."

I looked at her, confused. Sherlock probably noticed more than I did, but this girl looked healthy, clean, and well fed. How could she possibly not have a place to stay?

Next thing I knew, Sherlock and I were standing in the doorway, watching this girl bounce around the room.

"I'm going to live here!" She squealed as she ran about our humble flat, carefully taking in every small detail it had to offer.

"I can't believe she talked us into letting her stay here." I muttered, more to myself than Sherlock. "I mean look at her, she's running around and rummaging through our things."

"Fascinating." Sherlock grinned, watching the girl with amusement dancing in his eyes. "She exhibits no fear whatsoever at staying in a flat belonging to two strange men. Almost like…a pet." He then looked towards me, grinning that impish grin of his and clasping his hands underneath his chin. "Can, can we keep it?"

I gave him a small frown of disapproval as I answered him. "Fine, but you're taking care of it."
