Hey, I'm baaaack! I hope this conclusion works for you, and I promise that I will have drabbles coming up. (So author alert me if you want) Thank you to all of my precious reviewers, you guys really inspired me to continue with this story and have given me and Petri countless amounts of cuddles and hugs! I love you all like Sherlock loves John (Which, in my opinion, is a heck of a lot).

Disclaimer: *Looks to the sky* Wait for it... Dang! Benedict did not drop out of the sky. I am so dissapointed.

Sherlock might have loved John, but he was still a sociopath in every other way. So, when he burst through the doors of the pound and demanded that they release Petri at once on police orders, he didn't understand why John and the lady at the desk just laughed.

"The allergic flat mate, I assume?"

John nodded, still laughing in that infectious way of his.

"Well, I had a feeling you would be back so I didn't file anything. Wait right here." The lady smiled slyly and slipped behind an employee only door.

Sherlock looked at his friend with a slight frown on his face. "Why would she do that? Why? Isn't that against the rules of this place?"

"You break rules for me, right? So it's a part of…"

"Sentiment. I realize that that's what it is, but she barely knows you."

John just shook his head. "So, are you planning on getting shots then?"

"What?"

"For your allergies, are you getting shots or taking pills?"

"Pills." Sherlock hated shots, they reminded him of times without his friend, alone and taking drugs just to cure his boredom.

"Are you sure? Shots are usually more-"

"John, I realize you're a doctor but I am not completely stupid when it comes to medicine. I will use whatever methods I prefer."

"Right, fine then." They stood there awkwardly for a minute, both trying to figure out what the hell was going on between them. John loved Sherlock as a friend, of course, and was slowly becoming convinced that he would never really end up with someone else. His past girlfriends had all proved that, he would choose life with Sherlock over them every time. However, did that really mean he wanted to be with Sherlock in the romantic sense? For some reason, the idea seemed laughable. Sherlock would never be the caring sort, it just wasn't him, and John wouldn't want Sherlock any other way.

Sherlock was struggling with the caring aspect as well. It was obvious that John had somehow broken through his walls, but the consulting detective could never really be affectionate like boyfriends and such were expected to be. John was just his doctor, his flat mate, his. There was no other way to put it, Sherlock knew John would always be there, and that was enough.

"John-" Sherlock was about to ask what he thought of their relationship, but was cut off by a small meow.

"Petri!" John's face lit up in an overjoyed smile, and Sherlock himself was trying not to grin. The lady started to hand the kitten over to John, but Sherlock cut in.

"Thank you, but I will be holding him for the time being."

"But I thought you were-"

"Allergic? Yes, but my condition has been greatly exagger- er-"Sherlock sneezed, and, avoiding the lady's smirk, quickly walked out the door.

John laughed, and thanked the lady. "No problem, your boyfriend seems very eager to have his pet back."

"He's not- You know what? Never mind, thanks again." John walked out, almost running into Sherlock, who was over his embarrassing sneeze and was absently stroking Petri's head. "You're only going to sneeze more if you keep touching him."

"He's my kitten, It's only logical that I get to hold him." Sherlock held Petri even closer, almost making him invisible against Sherlock's coat.

"Why do you keep saying that? You do remember that I found him, right? Or did you delete that?" John stared at his friend in confusion, wondering when he had gotten so possessive.

"You also gave him up. I decided to come and get him, therefore he's mine. Obviously, John, do keep up."

"Yeah, but before that you said my kitten, remember?"

"If you ever used your brain and observed you might find that I treat everything in that flat like it's mine. Petri was in the flat and so I deemed it appropriate to call it mine."

"Yeah, but c'mon…Everything? I'm in the flat and you don't-"Sherlock cocked an eyebrow, curious to see what John would say.

"Oh. I see what you mean. So basically, nothing in that flat is really mine, is it?"

"Well…" Sherlock sneezed again; Petri was climbing up his coat and batting at his curls. "You have me. And I suppose we could share Petri."

"You really are starting to get a hang of this sentiment thing, aren't you?"

"I'm a genius, John, did you really think it would take me that long?"

"Judging that most people master sentiment at age one, it's has taken you about-"

"Thank you John, you can shut up now."

"Fine. Can I hold Petri?"

"No."

"Ok."

The pair looked at each other, and burst out laughing, remembering the first time they had made that exchange. Petri meowed, upset by Sherlock's sudden shaking. Unfortunately for the kitten, that only made him and John laugh harder.

A few weeks after rescuing Petri, John sat on his armchair writing on his blog while Sherlock lay on the couch in his infamous thinking pose. Petri was sprawled out protectively next to his petri dish of milk (They had figured out that Petri refused to drink out of anything other than his namesake).

Suddenly, Sherlock opened his eyes. "John, get me Petri."

"A petri dish?"

"What? No! Don't tell me you've forgotten that our cat is also named Petri."

"No, I just didn't think you'd want him while you're thinking."

"John, I need Petri."

"Please."

The doctor sighed, getting up out of his comfortable chair to grab the unsuspecting feline. Petri struggled at first, but when he realized where he was going he stopped. John gently dropped the kitten into Sherlock's waiting hands, affectionately shaking his head.

"Thank you." A few weeks ago, John would have fainted in shock at these words, but it was slowly becoming a common thing. For some reason, opening up the door to sentiment also helped Sherlock get some manners. Some, mind you, not a lot.

"You're welcome."

"Mmm." Sherlock nodded in acknowledgement, happily watching Petri curl up on his chest and start to purr. "John? Have you ever noticed that you're similar in your actions to a kitten?"

"God no, Sherlock. Probably because I am a soldier and I can't imagine what that has to do with being like a kitten."

"The facial expressions, John. Like when you turn your head slightly. Petri does that too, when he's listening."

John sighed, shutting his laptop off and turning to look at his friend. "If Petri looks like anyone, it's you."

"Me? Are you really going down that path? Comparing me, a sociopath, to a warm cuddly creature?"

"Not all kittens, specifically, just Petri. You know, black fur, black hair, complete indifference to everyone he meets…"

"Not everyone. He loves you." Sherlock slightly mumbled this, scratching Petri behind his ears.

"Right." John smiled, passing by Sherlock on his way to the kitchen. "I guess if we're counting by who Petri loves, which is me and you, I am a lot like him."

Sherlock smiled, "Told you."

During the last few weeks, all tension had disappeared, leaving John and Sherlock to simply carry on with their adrenaline filled lives. In the few relaxed moments like this one, both the detective and his doctor were left to wonder what they were exactly, but the one difference was they didn't really care about the answer. For Sherlock, it was a new sensation, but he was starting to accept the new feelings as a part of sentiment. John, being the one more used to sentiment, had probably gotten farther on the whole relationship than Sherlock had.

They had been walking into a crime scene, and Donovan had greeted them as usual. "Hello, Freak and Freak's partner." John was used to her name calling, but she had never used the term partner before. It was surprisingly accurate. John and Sherlock were best friends, and almost inseparable now. As long as they were alive, they would always be Sherlock and John, John and Sherlock. Who knows what that entails, or what could happen in the future. They were just the doctor and the detective with their cat named Petri. And that, my friends, was that.

*Sniffle* Ok, well I'm too emotional to think of anything else to add. I love you guys so so much, thanks for your loyalty! Alert me for the drabbles, and if you have any specific Petri/Sherlock moment requests feel free to message me!
