Chapter 3

1852 (1)

"This cannot be good." A red-haired boy with an eye patch said after Allen mysteriously vanished. Lavi was busy discussing something with Allen, but then he suddenly vanished out of thin air. "I have to tell Komui…" Lavi ran as fast as he could to the science division, as he burst through the door, papers went flying everywhere. He scanned the room for Komui's usual messy desk, but instead he found only a heap of paper. Somewhere buried beneath all the paper, was Komui.

'Okay, this is an emergency and now I have to go and dig through all of the paper to find Komui. Just great.' Thought Lavi. I'll just have to use the shortcut, that'll save some time finding him, although it's highly dangerous.

"Yuu-chan kissed Lenalee!" The heap of papers went flying everywhere and a fuming Chinese man with a beret and glasses emerged.

'NOT MY SWEET AND PURE LENALEE! BRING KANDA HERE IMMEDIATELY SO THAT I CAN PULVERIZE HIM WITH MY NEW AND IMPROVED SIR KOMLIN VI!" Komui looked ready enough to even destroy the Millennium Earl.

"Relax, I only said that to wake you up!"

"Why would you need to wake me up?"

"So that you can help out with the work." Reever said whilst carrying a heap over papers.

"Also emergencies." Lavi explained.

"What happened?"

"I was talking to Allen earlier and then the next thing I knew, he just suddenly vanished."

"Describe vanish."

"He literally just disappeared out of thin air. He was there, and the next moment he wasn't."

"Was there any fading or flashing happening?"

"No, he was just suddenly gone."

"Well, surely you bookmen have some sort of explanation for this!"

"As far as I'm aware, this is the first time this has ever happened. It hasn't been recorded yet."

"I'm sure he's fine, if he isn't, then we've just lost an exorcist."

"How can you say that so casually?"

"Because I know he's fine. Although I can't explain the vanishing thing, I'm sure he's just lost somewhere. And when he finds his way, he will be back."

Lavi thought about this statement for a while hoping that Komui was right. After a while of consideration, Lavi decided to trust Komui on this one. "You're right! He's probably just lost somewhere! He'll be back before we know it." He paused for a while. "What do you mean by Sir Komlin VI?"

Back to the Present

Somewhere in the Hogwarts Castle, there was a certain white haired boy, hungry and frustrated, because he is lost and he doesn't know what to do. Needless to say, yes, Allen has once again gotten himself lost. "Achoo!" He let out a small sneeze. God knows how he got lost because he was following someone he was sure is reliable. But it seems that the person he was following was actually a fourth year student and he was now at some place that is indeed not Defence Against the Dark Arts. After a while of aimlessly wandering around, he finally made it to Defence.

"You're late, Walker!" A very toad-like woman yelled out. Allen remembered her from the night he first arrived at Hogwarts. "I will be seeing you after class if you don't mind. Take a seat."

"Yes Professor."

"Now, earlier we were discussing the Millennium Earl and his akuma, were we? Wait, we were? Oh right, of course we were. Am I right?" Umbridge had a very confused expression on her fat face. It was priceless.

Hermione put her hand up. "No Professor… We were talking about vampire bats." Hermione told the seemingly confused teacher. "I think… No, we were talking about the Millennium Earl and how he used to work together as a team with you-know-who after he destroyed the Black Order on the 6th of February, 1852."

"What? What are you guys talking about? That's impossible, there's no way that could've happened! No way! You're lying! The Black Order is meant to defeat the Millennium Earl, not the other way around." Allen was confused and upset and he was refusing to believe what he just heard.

"Calm down Walker! You obviously know nothing because you are living in a little fantasy world inside your head! Now please open your textbooks to page 256." Umbridge told the class.

"But professor, this page is on vampire bats, not the Millennium Earl." Allen told the teacher after he had finally calmed down.

"Hands up when you tell me something in class, and what you are talking about, this page is about the Millennium Earl!"

"No, it's on vampire bats, look at it properly!" The professor didn't seem to hear Allen's comment and just continued to write something on the board about vampire bats. Allen raised his hand. "Professor?"

"Yes Walker?" She asked in her sickly sweet voice.

"This page is on vampire bats."

"Of course it is, that's currently what we're discussing. You should know this, you've been here for the whole lesson have you not?"

"But he just came in, like, five minutes ago!" Harry told Umbridge. "You gave him a detention for being late!"

"No I didn't and how many times do I have to tell you to raise your hand during class? Allen has been here for the whole lesson and I never gave him a detention! Or would you perhaps like one?"

"No professor…" Harry trailed off.

Hermione put her hand up. "Weren't we busy discussing the Millennium Earl and the Black Order?"

"No! I don't even know what an akuma is, and the Millennium Earl is just an old wives tale." Said Umbridge.

'Something really strange is going on here… First the teacher thinks we were discussing the Millennium Earl and the destruction of the Black Order, then she completely forgets about it and also the fact that I was late. Harry remembered although I'm not so sure about Hermione or the other students, but Hermione on the other hand, said we were talking about the Millennium Earl, etcetera. What's happening?'

Hermione was in the library looking for something. Obviously a book, otherwise she wouldn't be in the library.

"Hermione!" A voice behind her said.

"Yes Harry?" She turned around.

"I have to talk to you about something really important."

"Um, what is it?"

"I'm just going to get straight to the point. Sarah told us she saw you kissing Malfoy and don't even try to say she was lying, she didn't look like she was lying at all. So, why were you guys kissing?"

"… You found out about that, huh? It's true, I won't deny it. But just hear me out first before you go and blab this out to the whole school."

Harry looked slightly offended by that statement. "Go on."

"I was under the effects of a love potion. It wasn't a very strong one so it only ended up making me confused about my feelings. How he gave it to me I don't know."

"Do you know why he gave it to you?" He seemed slightly disappointed, almost as if he was envying Malfoy.

"Yes, but I was told by Dumbledore not to tell anyone."

"So you can't tell me why?"

"No, but you can find out for yourself. Use your head because when you're determined, you can figure things out for yourself. From what I've observed you're almost there. Now please excuse me, I'm looking for something. See you later."

"Wait! In class you said something about someone called the Millennium Earl and the Black Order. What are they and where did you hear about them? We were talking about vampire bats when Walker walked in."

"What do you mean when he walked in? He was there the whole lesson and we were discussing the Millennium Earl and a 19th century organization known as the Black Order. You should know, you answered one of her questions. No wait… we were talking about vampire bats… I think…"

"Actually, I think you're right, we were talking about the Millennium Earl. Walker had that outburst in class when he heard that they were destroyed."

"What's the Black Order? Oh that's right! That's why I'm in the library, to see if I can find a book about them!"

"About who?"

"Maybe we should go eat dinner first, just to clear our heads. It almost feels like something keeps rewriting my memories."

'What the hell is THAT?' Allen thought. He probably wasn't the only one thinking that, because there were many other students who were also crowded around a strange 'thing' in front of the Great Hall. 'Is this what everyone was talking about earlier today?' The thing that everyone was looking at was a small black orb of nothingness with strange looking heat waves emitting from it. But it wasn't hot, it was cold.

"That's…" Allen turned around to see who was speaking, it was Hermione. "This cannot be good! This cannot be good! Harry, I'm going to the library again, eat dinner without me."

"Allen Walker, can you come with me for a bit if you don't mind?" It was Malfoy.

"Sure, but what is that? Also, can we hurry? I haven't eaten since yesterday and I think I'm going to faint if I don't get something to eat soon." Allen's stomach grumbled to help make his point.

"What is that? A dying whale?"

"It's my stomach…"

"Oh sorry! And I'll be quick. Just follow me." Malfoy started walking in the direction of what Allen believes to be the library. Allen surprised himself when they arrived at the library because that means he is just one step closer to not getting lost. "I think it's pretty obvious that that thing has something to do with the spell. That looked kind of like the thing that appeared before you arrived. What do you reckon mudblood?"

She appeared from behind a bookcase. "I think you should both shut up because I am looking for something that I saw in third year. It may or may not help explain what is going on. Can you also please stop calling me mudblood? How would you like it if I kept calling you ferret or dickhead all the time?"

"That's not fair, I'm only calling you by what you are."

"So am I, dickhead, now please excuse me. I have to find this book." She went back to searching.

"Stupid mudblood…" Malfoy mumbled.

"Do you have a crush on Hermione?" Allen asked him.

"What? W-why would I?"

"Because you act really mean and disrespectful towards her."

"I do the same with her friends."

"Except you specifically pick on her."

"S-she's a mudblood!"

"And I'm not an idiot. I may come from 1852 but that doesn't mean I don't know how a guy acts when he likes a girl."

"Okay fine. I have a crush on her; I've had one for a few years now."

"Why haven't you confessed?"

"Because my father would be upset if he found out I like her and because she likes Harry. I'm pretty sure he likes her as well."

"Tell her."

"Sorry?"

"I said tell her. It's better to get it over and done with and who knows? Maybe she likes you."

"Do you like anyone?"

"No I don't."

"Since you're from 1852, does that mean you have an arranged marriage and you don't like the girl?"

"No, I grew up on the streets and therefore I don't even know my parents. They abandoned me because of my hand. At least, that's what I assume."

Hermione came back with a book and a worried face, thus ending Malfoy and Allen's conversation. "I found the book I was looking for, basically what I managed to figure out is that if we don't get Allen back to his time soon, we're going to have quite some trouble."

"Would you mind explaining?" Malfoy asked.

"Well, I know what that thing is now and it is seriously bad news. It's something called a 'RITAS' meaning Rip In Time And Space. A RITAS is formed when something from the past has moved out of its actual time and into the future. The size of it depends on how important the individual or object is and how big of an impact it'll make when moved out of their own time. What a RITAS does is cause a paradox. Have you guys heard of it?" They shook their heads. "It's when time breaks and you get two types of paradoxes; a muggle one, which explains what happens when you meet yourself. Then there is the one explaining our situation.

"First I'll give you the muggle description of a paradox. It's basically when you travel through time and meet yourself. In the show, Doctor Who, it happens when you come in contact with yourself. In other words, you can still talk to yourself, but as soon as you make contact, basically, time breaks. That's the best way to describe it. How important the individual is will depend on the size of the break or whatever. You might either faint or the universe might explode, that isn't very accurate, a more accurate description is from the movie, Back to the Future. Basically, they give the same outcomes but you only get those outcomes if you see yourself. Again, depending on the importance of the individual, the outcome may be either big or small. But this type of paradox only applies to when you travel back in time where there will be two of the same person. It can't be caused by a RITAS.

"Then the one that will apply to our situation. This type of paradox is caused by a RITAS. Like I said, it forms when someone from the past is brought into our time. Because history is already written, removing someone from that history will cause time to break. Depending on the individual the effect might be either large or small. And when I say time breaks, I don't mean fainting of people but it can cause the universe to explode. Well, that's the theory anyway. But what it does is causes history to rewrite itself. It can leave confusion and generally things to do with memory, hence what happened in Defence Against the Dark Arts. The longer the person who stays in the time he is not meant to be, the more likely history will rewrite itself. Now Allen, you aren't the only case, it has happened before, but those people made it back to their own time or they just became part of this time without changing history dramatically. But they weren't such a big part of history. You on the other hand are." Hermione produced another book. It was old and dusty and the title read, The Black Order. "Recognise this, Allen?"

"Um, yes. Komui finished making it a few weeks ago. Yet he still doesn't do his paperwork…"

"You're in it."

"I know."

"You're an exorcist."

"Yes I know."

"You're a pretty big part in history then."

"That's why I need to get back."

"You don't understand. You're a bigger part of history than you may think. You were prophesised as the Destroyer of Time. I'm not quite sure what that means, but I think it means that you're such a big part of history that you will destroy time itself. At least, that's my theory."

"I think you're incorrect because I'm just an exorcist."

"You're also something known as the 14th Noah."

"What? What do you mean?"

"Oh crap… I may have just done something I'm not supposed to. Can I see your left hand?" Allen took his glove of his left hand. His hand was red and had a green cross embedded in the middle of it. Around the cross there were wrinkles. His fingers had indications of lines around the joints and his nails were black. "Yep. I think I may have just screwed something up, maybe, just maybe, if you go back to your time you will hopefully forget about what I just said because you aren't meant to find this out until after you… I'll just keep my mouth shut. Forget what I said!"

"Okay… Um, when you said earlier that history is starting to rewrite itself, I noticed a few strange things happening in Defence. You were saying that apparently the Millennium Earl destroyed the Black order on the 6th of February, 1852. That's about a month after I left."

"How long have you been here now?"

"About a week."

"Roughly three to four weeks in a month and if we want to be safe that means… We should try and get you back within the next two weeks. Otherwise… I'll say it so that you guys can understand, but, if we don't get you back soon. We're probably screwed…"

"Shouldn't we technically be screwed now though?"

"No, there's some kind of chain reaction… best way of putting it… Meaning that for the amount of time you spend here, the same amount will pass for when you left even if they are in separate times. For example, one month here is equivalent to you being one month away from your own time. Let's just deal with the fact that it doesn't make sense!"

There was a moment of silence for a while; they were busy thinking it through. Unfortunately the silence was interrupted by a dying whale sound. "Sorry, just my stomach… I should probably get something to eat. Bye!" And just like that, Allen left Hermione and Malfoy standing awkwardly next to each other in the library.

"So what did Hermione say?" Ron asked Harry nervously.

"She said that Malfoy somehow gave her a weak love potion. Bu what I want to know now is why he would be willing to kiss her. We all know that Malfoy hates muggleborns." Harry told Ron what he heard.

"Maybe Malfoy was being controlled by something?"

"I think you're right." Harry trailed off.

Suddenly, out of nowhere, a voice appeared behind Harry. "You're going off topic now…" It was Allen. "Last time I checked on you two you were trying to figure out why I suddenly started attending Hogwarts and you almost had it figured out. Also, Malfoy has a crush on Hermione, meaning he honestly wouldn't mind kissing her. How do I know what you've been talking about? Because I have been using you two as a guide for getting to my classes the whole day and I may or may not have been listening to what you two were saying. Unfortunately I get lost so easily that I sometimes lose the two of you. And how I got here now, well, I was just following my stomach. And now I'm going to have something to eat. Bye!" Then he was off again.

"I may be wrong, but I think he just gave us a huge hint. And Malfoy likes Hermione? What the hell? Ron, why are you blushing?" Harry said.

"I've told you before. He's adorable! I mean, look at that happy face!"

"Please don't tell me you have a crush on him? Because that would be incredibly awkward and weird."

"No, but you have to admit, he's cute. Just look at him." Ron gestured at the Slytherin table. Harry turned around. Allen was sitting there with a big smile on his face while eating heaps of food. He looked really happy that he was eating. He looked like he was younger than he really is.

"Aaaw… He looks so happy. It makes me happy! You're right! He's adorable! But also evil." Harry said.

"Yes, don't forget the evil. He'd probably kill us in his sleep if he had to."

"Where do you reckon that thing went?"

"Dunno, it just disappeared. But I have a really bad feeling about it..."

1852, one week after Allen's disappearance

Komui was running throught the halls of the Black Order. He was in a hurry and needed to get to his destination quickly. When he arrived he was shocked at what he saw. There was a black orb with strange waves emitting from it. "Everyone calm down! Just leave it alone and don't tamper with it! Bookman, do you have any idea what this might be?"

An old, small man with thick black eyeliner and a grey ponytail went to investigate it. After a while, he spoke, "Yes, I know what it is. I advise you not to get too close to it for it may be fatal. This is what's known as a RITAS, it occurs when someone was sent through time into the future. Lavi, where did Allen disappear." The old man asked Lavi.

Lavi answered, "Around this area. Was he sent to another time?"

"I'm afraid so, and if we don't get him back soon, there might be serious outcomes."

1. This is the time that D Gray-Man is set in. From what I've seen there are two indicators in the series that this is roughly the time it's set in. The first one was episode 7: Tombstone of Memories. It shows the date when they show Leo's mother's grave around the end of the episode. It said 1818-1851 The second is one of the filler episodes (Can't remember what it's called). It was in the Missions Arc I believe. Again, I saw it on a grave, and it said 18?-1852 (I think because I haven't watched that episode in a while.) The February thing I just made up, because they never really say the date.

2. Haven't gotten my friend to edit this one yet, so if I got anything wrong, please tell me and I shall fix it like Fix it Felix

Anyway, thank you for reading and thank you for all the reviews! I really appreciate it! :P
