"Good evenin' Missus Janis!"

A woman who looked to be in her 50's turned around and gave a small smile to the shopkeeper. "Good evening James. How have you been lately?"

"Doin' just fine missus, just fine!" The large man said with a smile. "You seem to be picking up more food than usual today, don't tell me that you're enterin' the datin' pool once more, are you?" He said, giving her a smirk.

Janis gave a small laugh, "Oh no, of course not James. You of all people should be aware of that. No, I have a new tenant that I am renting the flat to." She pursed her lips, "Unfortunately, he hasn't left the place since he signed the documents, so I thought I would make him a meal, see if I can force him outside. It's not healthy to be indoors all the time you know."

"Ah, yep. I know the type" James said with a laugh. "So, is it anybody I know? Maybe somebody I should drop in on to be makin' sure he's treatin' his landlady right?"

"Oh hush James, you'll do no such thing." She said after giving him a small slap. "He seems like a very nice young man, very well behaved. He's new in town, but decently well off based on his clothes." She gave a quick sigh, "I feel a bit bad though, I have several rooms he could have taken that were much nicer than the one he chose, but he was quite insistent. Said it reminded him of his old place."

"Huh, so what's the lad's name?" James asked

"Oh, it's a bit odd, never heard it before," Janis said with a small frown. "Tell you what, you can come over tonight and talk to him. I'm sure he'd be happy to have another guy to talk with."

A man sat cross-legged in the middle of a room. The furniture had been pushed up against the walls, leaving the middle clean and bare. Or rather, it used to be clean and bare.

Personal Note: The Great War -
*Suspicious start, bad for everybody, why did it start?

Surrounding him were threads of various colors, crisscrossing themselves and connecting to various picture, news articles, and notes that he himself had written.

Personal Note: Merlot Industries
Suspicious lack of info for something that was so prominent in Mt Glenn before the place collapsed. Filed for later thought.

The walls were covered in notes he had taken, newspaper clippings that looked like he had removed them from a trash bin, pictures that he had printed off.

Overview of Grimm movements across Remnant:
Can't put too much faith in these, the truth is probably restricted to avoid panic. But if any of this is true, this shows far too much coordination than dumb beasts.

The man himself had his eyes closed in though, a violin in his hands as he played a haunting melody.

Jacques Schnee inherits Schnee Dust Company
Not popular at all. Why risk angering employees so?
Potential Cause: Dust is finite and running out, costs to find Dust increase, so payment to employees must decrease to keep status quo. Odds: 64% Good enough to keep. Shelve for later thought.

He found himself at the city almost a week ago now, and after he got over his surprise, he immediately started looking for more information. He wasn't like other Servants. Though he could fight, it most definitely was not his forte. Furthermore, his legends didn't portray him as a fighter, but as a thinker.

"Come one and all to see Atlas unveil their newest robots - the Atlesian Knight-200's! Coming Soon!"
Technology is clearly more advanced than what we are used to. And yet, less advanced in many other areas. Robotics, Dust, AI development... Is there ulterior motives? Or just survival? Dismissed for now. Note: Procure dust for personal investigation.

When first summoned, he had no doubt he was the weakest of all of the Servants. All of his main skills, and especially one his Noble Phantasms, require knowledge to work.

Personal Note: Sustenance
Have not eaten in two days, and have confirmed that this body does require food in order to sustain itself. Not to the point that a human body would, but nonetheless. Will need to experiment to see if various foods give better energy than others.

Natural Insight. Hypothetical Reasoning. His Noble Phantasm. All hinge on logic. Why people act the way they do, why they do things. From that, one can make logical leaps into what they will do, or what they did. A persons history, the city's history, and the world's history, are all small pieces of the puzzle that fit into his skills.

Personal Note: White Fang
Founder is retired, group has gone radical. Desired equal rights, news portrays them as wanting greater rights. Would estimate 30% are extremists currently, the rest just want to try to help. Can't do anything about this yet.

It was easy enough to get some money. He picked the pockets of some thugs that thought he was an easy target, and then found a gambling establishment. It was child's play to play the odds, and he left with decent amount of cash before the establishment decided to investigate him for being too lucky.

"New Headmaster takes over for Beacon - Headmaster Ozpin gives a pledge to do his best to protect not only Vale, but all of Remnant"
Interesting man. Heavily involved in many events. The Headmasters of the Hunter's Academies would know the most about Grimm. They are keeping secrets.

From there he went to the libraries. He didn't have a scroll yet, but there was a very nice lady who was able to show him where he could find the things he needed. He left the place with a couple bags of printed newspaper articles and books containing the various laws of the land.

Personal Note: Grimm types
Too much variety of Grimm. Swimming, flying, ground types. Most modeled after regular animals. Why? Possible magus experiment gone wrong. Or possible magus experiment gone right. Chances of them being Natural: 4%.

Now that he had had the time to do some research, he could properly set up his Territory in his Mind Palace again. Since most of the memories in his Mind Palace were no longer applicable in this strange land, and he needed to start from scratch.

"Pyrrha Nikos has won the Mistral Regional Tournament for the third year in a row!"
Interesting. Some influences are recognizable. Roman. Note: Look into Nikos's history.

Now he believed he had a decent amount of knowledge to activate an aspect of his Noble Phantasm. To enter his mindscape and attempt to answer a single question. Fully powered, his Noble Phantasm could take even an unsolvable mystery and place clues in the world to help him solve it. He didn't need to go quite that far at the moment. With what he was attempting, he really was just using an overpowered version of his other skills, using Natural Insight and Hypothetical Reasoning to extrapolate from his current knowledge events in the future and past, to answer a single question he had. It would be draining - he was weaker than usual here, and his knowledge was less than usual, which made it harder. He wouldn't be able to do it a lot until he gained even more info, so he had to make the question count.

"Murdered politician: Arthur Watts as a witness, describes the scene. Suspected Roman Torchwick"
Lazy investigation, poor conclusion, the witness contradicts the scene. Note: Send police a letter with details.

After a bit of time, he came up with a suitable answer.

What questions were there that he could ask?

Who summoned him? No, if he couldn't talk to the person, be they dead or out of reach, he would be back where he started.

Why was he summoned? Possible and tempting, but the potential for "worthless" answers was large. A 'whim', to save humanity, to destroy humanity. He didn't have a master, he could choose what he wanted to do. The summoner's desire mattered little in this.

Where did the Grimm come from? He doubted his Noble Phantasm had enough energy to determine that since he had so little knowledge of Grimm.

So what would be the best question to ask?

In the end, he wanted to help humanity to survive.

He stopped playing his violin and opened his eyes.

Staring at the array of information he had established, he placed his violin on the ground, and asked in a clear voice "Who is the person in the best position to help humanity to thrive?"

And as he closed his eyes again, he slowly answered back, "The answer to that, is Elementary, my dear friend..."

And with that, Sherlock Holmes entered his Mind Palace.

A few seconds to the outside world can last for several hours in the confines of ones Mind Palace. Composed of all of the knowledge he had gained, a territory protected by his skills as a Caster, and one he kept when he became a Ruler. Sherlock Holmes, the crystallization of the concept of what made a detective, could solve almost anything within his Mind Palace. For truly, it was his business to know that which other people didn't know.

Sherlock opened his eyes once more and stood up. Walking over to one of the newspaper clippings, he gave a small chuckle, "Well, I can't say I was expecting this." He tapped it a couple times and walked over to the newspaper piles. "I guess I better let Miss Janis know I'll be at the library later today. And maybe tomorrow. There's somebody I am going to have to research."

And with that he walked out of the room and locked the door. A picture of Weiss Schnee still fluttering after having been touched.

Weiss Schnee was walking through the empty halls of the Academy, shivering in anger. The teachers had spent a considerable amount of time trying to convince her to join Atlas Academy in eight months, and she had to endure listening to them give multiple reasons as to why Atlas Academy was better. She walked faster, her steps hitting the floor with more anger. Most likely they've been bought by my father. Or maybe they are just that patriotic she thought with a glare.

Right as she was about to leave the Academy, she heard a violin begin playing. Surprised, she stopped and listened for a little bit. She wasn't aware of anybody that could play a violin like this amongst her peers. The music sounded... lonely. Something that she sympathized with at this moment. Hesitantly, she started walking towards the sound.

She eventually reached the auditorium, where the doors had been flung wide open, and she saw a man on the center of the stage playing that song. She slowly walked down, but made sure to keep her distance. She didn't recognize this man after all. He looked like he was a few years older than she was, maybe in his twenties.

After listening to him play his song for a while she slowly relaxed. He eventually slowed down and stopped, opening his eyes to look at her.

She clapped for him a few times, and then asked "What song was that? I don't recognize it."

He looked like he was in thought for a bit, and then replied "Thank you Weiss, I actually wrote it. I think I'll name it Lonely, yet Defiant. Not sure how close I am to finishing the song though, so we'll see if the name changes by then."

As soon as he mentioned her name, it put her on guard. He clearly wasn't surprised by her presence, almost like he was expecting her here.

After a small standoff, she asked him "Who are you, and how did you get in here?" The doors required a pass key that only students and teachers had after all, and teachers did walk the halls to prevent miscreants from entering.

The man shrugged, "My name is Sherlock Holmes." He stepped off of the stage and sat down at one of the seats. "I actually just walked in before the door could close all of the way. The teacher walking the halls suddenly had something he needed to check halfway through his conversation with me," A small smirk appeared on his face. "I might have said something that concerned him..."

Weiss sat for a little bit, stunned that he actually told her all of that. She quickly stood up and started walking out of the auditorium while keeping an eye on him. "Well then, if that is the case, what are you doing here telling me this? Knowing of course that I am going to tell security right away..."

Sherlock looked remarkable unconcerned with what she was saying, and calmly said "Are you aware of what an Arma Gigas is?"

She looked at him oddly, "It's an early robot design, looks like a giant knight. There's currently one in the Schnee Museum. What does that have anything to do with this?"

He straightened his jacket as he stood up, looking at her in the eyes. "Your father dislikes the idea of you going to Beacon instead of Atlas. He intends to create a little test for you. He's looking for ways to procure a possession type Grimm, such as a Geist, and will have it possess an Arma Gigas. Then, he will tell you that you must destroy the thing. If you fail, then you will be forced to attend Atlas Academy."

Weiss felt like she had been punched. And the thing was, she could totally see it happening. That sort of thinking would totally be in line with what her father would do. Although even if it was the case, that didn't answer everything... "So what's that to you? Why would you care? And how would you even learn that information?" And where the heck were the professors?

Sherlock nodded at her questions. "I don't expect you to believe me right away. I recommend that you look for some answers yourself. Maybe ask your sister, Winter, if she has heard anything. She might try to talk you out of going to Beacon, but she won't play any underhanded games with you."

She gave him another glare, "I am aware of that, I know my sister! And I notice you haven't told me where you heard about it."

He gave her another nod. "Good. Not saying you don't, just making a statement. As for where I heard about it?" He let out an explosive breath. "The teachers are all complaining about your attitude and decisions, I think they mentioned the word 'rebel' quite a few times" he said with a smirk. "It was fairly easy to eavesdrop on them in the bars they frequent. They complained because they couldn't get you to do what your father wanted you to do."

She stiffened in anger at this, I knew it!

He continued. "During that conversation, they let slip that he wasn't surprised by this. And yet, at the last fancy dinner that he and General Ironwood had, he expressed his desires for the General to keep a spot open on the roster for you, according to the waiters. So clearly he has something in the works. Digging through your family's trash, I found several bags of shredded paper. Putting them together, I can see he has made requests to use an Armas Gigas for a project of his, and another request of his was for the military to try to find a Grimm that could possess an armament or robot."

She listened to his explanation in surprise and shock that he went to that length for this.

"Now, that was the brief version of what I went through, but I think that it gets the point across." he said, while giving her a small smile.

Once she found her voice again, she asked "Don't think I haven't noticed that you haven't explained why you are so invested in this. You are a stranger, and shouldn't have any interest in this."

He kept up his smile. "Actually, that's pretty easy to explain. I think we can help each other."

Her eyes shot wide open. She definitely was not expecting that. "Help each other? How?"

He gave a shrug. "I want information. Information that you have easy access to, what with your connections. Nothing secret or confidential, just stuff that I can't get my hands on very easily. In return, I would like to teach you."

Her look turned incredulous. "You? Teach me? And what exactly do you think that you could teach me?"

He reached inside his pocket and pulled out a paper. "Do you know how many weak points there are in a standard Atlesian mecha soldier?"

Weiss thought about it for a second, "I imagine there would only be a couple."

He tossed her the paper. Catching it, she looked at it suspiciously before opening it up to see roughly drawn pictures of the outside of the mecha soldier... along with hand drawn notes specifying 32 weak points and vulnerabilities that could be exploited. She looked up at him in shock. "How did you get this?"

He shrugged. "Figured it out myself. Read the technical journal that came out for it and observed a few videos of them fighting. Wasn't too difficult at all. You could say that it was quite, elementary." He chuckled to himself as if he had said a private joke. "Anyways, although I do know a few fighting styles that could benefit you, I think that the most valuable thing I can teach you is how to observe things like I do. How to observe the enemy, figure out why he does what he does, and from that, create a battle plan to defeat him. Also, I will throw in the designs for the Arma Gigas, and explain what you need to do to defeat it. And if I am wrong?" He gave a scoff, as if such a thing would never happen. "What I teach you should be able to help you defeat whatever it is that your father throws at you."

She stared at him for a while. On one hand, this man was suspicious, but it didn't seem like he was lying, and if correct... It could really give her an edge.

He spoke up once more "No need to decide now. Talk with your sister, see if she is aware of the Arma Gigas plan. Here," He brings out a paper and writes an address on it. "You can find me at this address if you are interested. Any training that I give can be done in public locations, well within any bodyguard that you feel like bringing, or amongst any crowds that you feel like."

She gave him a slow nod, "Thank you. I shall look over your story, and give you my decision later." She looked at the address. 221B Armas Lane?

She then walked out of the room, making sure to keep him in plain sight. She wasn't a fool, and this offer came at a very convenient time. She would give it a lot of thought before she decided anything. She wasn't sure about the training he was talking about, but the weaknesses of the Arma Gigas could be very useful. She then started walking towards the Schnee Manor, hoping that Winter would be available for a talk.

Sherlock calmly watched her as she exited the building. Yes, he was aware that what he did was very suspicious. But there wasn't ANY good way for this to go. As it stands, he was able to give her the info, and make the offer to her. He's letting her contact him, and given her explanations on how he found everything, and was upfront in what he wanted. Honestly, this was about as good as it was going to get he believed. He started walking out of the school and to his flat. Miss Janis was very insistent that he have dinner with her and one of her shopkeeper friends, and he was very much aware that it was never a good idea to upset your landlady, giving a small laugh as he remembered Mrs. Hudson.

Training Weiss in observing people will also help her in understanding other people a bit. With any luck, he'd be able to help her with some of that trauma she has.

He shook his head, clearing his thoughts. He couldn't get ahead of himself, she still might refuse. In which case, he needed to come up with a plan on what he would do...

No, this certainly wasn't what he thought would happen when he used his Noble Phantasm, but he would take it. This gives him a goal to work towards, and he'd be helping somebody who was in a position to do quite a bit of good in the future.

He gave a small smile as he walked back to his flat, saying softly to himself "The game is afoot. Not a word, and into your clothes and come!", and he slowly disappeared walking down the street.

Authors Notes:
Regarding the answer Sherlock got from his Noble Phantasm, I will specify that it gave him the answer based off of all of the information that it knew and could extrapolate. If he had information from all over Remnant, his Noble Phantasm might have said that Ruby was the best person.

Anyways, let me know what you think about this chapter. And also, I feel the need to congratulate Midnight49. He guessed that Atlas would be the next place, and came pretty close with who the next Heroic Spirit would be. He had guessed Jack the Ripper, which was close to Sherlock, but no cigar.

I hope that everybody enjoys this chapter, and I thank you all for the support!

EDIT:
I apologize, I just realized I should specify a couple of other points that might be confusing.
1. Regarding the newspaper articles that sherlock had pinned to the wall, they were a mixture of current and old newspapers, which is why one of them mentioned Ozpin becoming Headmaster.
2. Regarding Sherlocks approach of Weiss. This is just an opinion, but I have always envisioned Sherlock as being somebody that can manipulate and act really well when he wants to get information, but when he is with friends or with people he doesn't care that much about yet, he is very blunt and explains everything. Does that make sense?
