Ill add it in soon but for now heres the long awaited chapter 4 =D

Please review if you enjoy this as if it isnt very popular I may discontinue an focus on my other story(s - working on other ideas)

Mephisto closed his eyes as he stood in his office. Amiamon was off somewhere no doubt misusing the dimensional keys he had given him so he didn't have to bring his younger brother with him. He waved his arm and closed his eyes. He took a step forward and felt a familiar sensation of being pulled through time. He opened his eyes as he gently floated but at the same time was propelled at high speed through time, searching for Sebastian. He saw numerous 'tunnels' fly past him that lead to different places and periods of time. He knew what he was looking for, finding it was a different story. As he floated/shot through time for what felt like hours, he finally noticed a tiny black thread, the 'trace' left behind when a demon traveled through time. His own trace was an extravagant white and gold weaved rope which amused him as it reminded him of the golden rope that held back the velvet red curtains at an old theater. He smiled to himself, the black string suited the simplistic butler who's soul was black and had one simple purpose, as simple as the string Mephisto reached out and grabbed. He was jolted forward with a force that almost took his breath away had he not have felt it himself many times. As he was pulled through time, twisting through the tunnels and occasionally being sharply pulled into a different direction, he became aware of the strands of film that laced the flashes of colour that whizzed past him. He smiled to himself as he was being pulled into a short period of time where a group of demons had congregated and called themselves reapers, Their reign and influence had been short lived as after 40 something short years of existence, Satan had decided to wipe them out, why he didn't know but he had long since lost interest in finding out, He may ask Amiamon if he could pay a visit to Gehenna and dig anything up. He was suddenly thrown from the tunnels of time and landed gracefully on his feet, leaving behind his trail of thoughts. The tunnel he had just een spat from dissapeared. Dusting off the lapel of his white exorcist jacket and looked around. He appeared to be in a luxurious mannor which was impressively kept considering the time. The decor suggested that he had landed somewhere in the mid to late 1880's. Before he could take a step to examine anything, Sebastians voice care from behind him, He had expected this.

''Good evening my old friend. What brings you here?''

''You seem to be awfully on edge crow. Where you expecting me to come here to declare war?''

Mephisto felt the cold metallic feel of a blunt knife touch his throat. He sniffed, absorbing the scent of tinted silver.

''Alas, that explains why are brother Rin is taking so long to heal. Do I detect the scent of blessed Iron? I can only guess that you had them specially made for such an occasion. Or where you hoping to use your custom silverware to defeat are dear father?'' He said, a smile in his voice. Even to him, these weapons could be deadly. Demons are weak to Iron, it slows down their supernatural healing to about half its potential. ''You caused quite a stir at my academy, I was enjoying watching him stumble around while he tried to hide his demon inheritance. You ow me for that.'' Their was a moments silence before the knife was withdrawn. Mephisto turned around to see the familiar figure of his old friend.

''Samuel. It has been a long time. May I ask why you have decided to pay a visit to the honorable home of Phantomhive?'' The demon bowed, his demonic smile that could weaken the knees of any woman while making her want to run for her life spread across his face. ''I see you haven't changed.''

''Oh you are as charming as ever.'' Mephisto bowed regally himself. ''I simply came for a little chat. May we sit and have some Tea?''

''But of course.'' The butler lead Mephisto into a luxurious reception room full of old English charm. Some may call it gaudy but to Mephisto, it held nothing but fascination. Sebastian swept around the room lighting candles while Mephisto clicked his fingers and his favorite floral teapot with two tea cups appeared. Sebastian returned and sat in the sumptuous sofa opposite the one he sat in, A low coffee table made of expensive Mahogany sat between them. The tea cups settled on the table where the teapot poured its steaming content's into the cups of its own accord. Sebastian smiled that beautifully deadly smile.

''Japanese Gyokuro Green Tea with a hint of honey. Quite the unique infusion, A fine invention.'' The butler mused as he picked his own cup up and sipped it. Mephisto smiled.

''Also known as Umimi, Still as sharp as ever I see. Do tell me, Who's unfortunate soul are you after this time? I would not expect to find you somewhere so grande. Have you abandoned your dream of defeating your old master and are simply living the high life or is there more to it?'' Sebastian narrowed his eyes. Mephisto smiled. ''Do I detect defense? Is this one so special?''

''You have no idea.'' He said dismissively, continuing to sip his tea. ''Lets set aside the idol chit chat. What is it that you want?''

''Oh we will get to that, I would simply like to catch up with an old friend. For you it has been 100 years but this is over 100 years in the past from where I come from. I believe that I was in the process of building my academy at this time. Please tell me what you have planned, I am curious as the birth of are young Rin back in my time is evidence that you are still no where near your goal.'' The demon before him's eyes narrowed, a look that drew any life that had previously ben in the room, leaving behind nothing but cold emptiness. He closed his eyes and cleared his throat.

''I am surprised to here this as the soul that I am...neutering right now should have given me all I need.'' He cupped one elbow with one white gloved hand and rested his chin on the back of the other hand thoughtfully. Mephisto smiled and flung an arm out to the side in a theatrical gesture.

''Well I thought I would pay you a visit and propose a wager. Are young Rin Okumura has shown great potential once his flames awoke. His ultimate goal is to defeat Satan and I believe that, with the appropriate training, He may have a chance at succeeding, provided that you offer up your assistance that is.'' Mephisto narrowed his eyes in challenge at the demon before him. ''At the moment you could have a fair chance at defeating me if you wanted to, The fact that you didn't makes me believe you wanted to her what I had to say, maybe you have some questions of your own?'' The demon didn't waste a breath on small talk, Mephisto was surprised with his abruptness.

''Why was he able to summon me.? You mentioned him having potential but could that stretch to him being capable of summoning demons of my status from another time?'' His expression was of wonder, almost distant as if he was asking himself.

''I do not believe that he is THAT capable but the fact that it is the blood that runs in his veins that wrote the seal that suppresses your true nature.'' Mephisto mused, sipping vacantly.

''Is that so?'' again, Sebastian appeared to be asking himself. He cleared his throat again and adjusted his bow tie, eyes still closed. ''Even that aside he truly does hold potential. ''I did sense the blood commanding me but I was unsure of it was to do with him summoning me or if it was the seal. I am assuming that are tie works in similar ways to a summoning, I was able to act freely once his will had broken. I must say It was thrilling to unveil him before his friends.'' The demon smiled with satisfaction, a sadistic thing that Mephisto suspected maniac's wore as they looked at the maimed remains of their victims, It made his tail quiver around his waist. Although Mephisto would never admit it to himself, he knew that the demon before him could kill him if he wanted to, his ancestors where only tamable via Satans powers, The strength of each sub family resided below their masters and above the next king in line. Sebastian had the potential to overcome Lucifer if he wanted to. He set aside the thought and returned to their conversation.

''The wager I spoke of before. I was going to suggest that, provided that you are summoned again, You try to make some form of agreement with my baby brother. You can show him how to reach his full potential using your knowledge of how Satan himself used his and maybe you will find that he has the potential to open a Gehenna gate, even if you do not want to proceed with the boy, you can enter gehenna and face Satan once again.'' Sebastian's eyes narrowed.

''And what would you gain from this?''

''You know what I want. Humans are far more entertaining that anything in gehenna, I simply want to observe as they struggle through their lives and enjoy every entertainment they invent.''

''Any what if we cannot come to an arrangement or the boy turns out to be unable to reach his full potential?''

''Oh I can assure you that he can, he can be...difficult at times but he certainly has the ability, you will probably enjoy motivating him.'' Mephisto said, knowing the offer to torment a soul would tempt the demon before him. As he expected, that sadistic smile returned. ''If it does not work, you simply return to your business here and I in Japan.'' Mephisto waited as Sebastian turned the idea over. He knew the tailless demon would agree, it was simply to good an offer to refuse. Mephisto stood up, ''I will leave you to decide but I believe that the boy will be summoning you soon. I request that you do not kill him if you decline my offer but I do recommend that you give it plenty of thought.''

''Still the same old devil you where back them. Thrilling me with your offers and then leaving me hanging.'' The demon chuckled, a strangely sophisticated sound. Before either demons could say anything else, their was a blur of movement as something wearing red with matching hair rushed between the two and wrapped itself around the now standing Sebastian.

''SEBBY! HOW COULD YOU!? And I thought you where simply discussing your naughty demon matters. Whats this I heard about Satan? And who the hell are you?'' The strange demon finally turned to Mephisto who simply bowed, an entertained smile splitting his face.

''My My, I never thought I would have the pleasure of meeting a reaper, especially as your organization is wiped out some time during the humans second great war.'' He looked up with knowing mischief and the red haired reapers jaw literally hit the floor. He turned to Sebastian with a demanding expression.

''WHAT is he talking about Sebby, who is he?''

''I am surprised you are unacquainted with the king of time.'' Sebastian said, amused as the reapers expression went blank and he mechanically turned his head back to mephisto who was still bent in introduction. ''He decided to pay me a little visit from years into the future.''

''W..W...WHAT ARE YOU DOING HERE? YOUR NOT HERE TO TAKE AWAY MY SEBBY ARE YOU?''

''Not at all, I have long since abandoned my duties back in gahenna. I am merely offering a wager.'' He winked secretively at the red head who actually blushed. ''And I believe you would be stealing him away from me, given that we have been acquainted for over 100 years.'' Once again the reapers jaw hit the floor before sitting in the fetal position while he clutched Sebastian's trouser leg, eyes creating waterfalls at either sides of his face.

''Tell me it isn't true sebby! We where supposed to be wed and have babies and I was supposed to be your first!'' Much to mephisto's amusement and in Sebastian attempt to further depress the red head, he swept around the table and lifted one of Mephisto's hands, bringing the other around his waist and proceeded to spin him in a elegant waltz around the room while the reaper continued to waterfall and whine aloud. After so many steps they would, completely in sync as they had done many times before, change their positions so the 'lead' shifted from Mephisto to Sebastian and back.

''Aaaah, the times we spent dancing like this,'' Sebastian taunted.

''EEEEEEEH?''

''The candle lit dinners we used to share!'' Mephisto continued.

''DWAAAAAH?''

''Those LOOOONG nights we spent together. Nothing more than are passion to stop us from freezing to death'' Sebastian theatrically bent down on one knee and took Mephisto's hand, Mephisto feigned a swoon as Sebastian took his outer stretched hand and planted a kiss on it.

PPPPPPPPFT! #Grell, RIP, died from nasal blood loss#

''We simply MUST do it again my love.'' Although They were both acting to extract some amusement from the red haired demon, Mephisto couldn't help but blush at the memory of what REALLY happened... (I will leave you to your filthy imaginations! XD)

''HOW COULD YOU DO THIS TO ME?'' The reaper shouted while he sat in a puddle of his own tears. The scene suddenly froze in place as one of the highly polished mahogany doors screeched open, from behind it appeared the head of a small boy with jet black hair and an eyepatch. He looked around with blank curiosity as he took in the scene.

''Sebastian, Grell, what are you doing at this hour? And who might you be,'' His attention turned to the unfamiliar face of Maphisto who was still holding Sebastian in their frozen position. Sebastian let go and stepped back from him, his smile of cruel amusement still on his face as he smoothed down the creases of his already perfect uniform.

''My apologies master. This is Mephisto, an old acquaintance. I will see are uninvited guests out, please return to your chambers.'' The boy continued to stare but dropped it and closed the door behind him. Sebastian turned towards the two.

''I would kindly ask you both to leave. Mephisto, I believe I will be seeing you again in the near future. Grell, please leave.'' With that, the demon bowed ferwell and turned to leave. Mephisto looked at the reaper who stood up still looking exaggeratedly upset. He laughed.

''I bid you adew. I DO hope we can meet again in the future, I simply adore the colour red. Might I advise that if you wish to preserve your life, you leave the reapers no later than 1902, that is when my father decides to dispose of you all.'' With that he bowed regally as he had to Sebastian and once again stepped into the portal. He instantly saw his own trace and grabbed onto it, smiling to himself as he was left with the image of the red clad reapers eyes turn into hearts.

Hi again, I'm really sorry for such a late update. I've had a million an one things to do and I sort of kind of got addicted to writing my other ane fanfic #blush#

I honestly don't know what happened but its just...not their anymore, I bet quite a few of you where scratching your heads thinking waaadafuu? At the beginning of chap 3. Ill add it in soon but for now heres the long awaited chapter 4 =D

He opened his eyes as he gently floated but at the same time was propelled at high seed through time, searching for Sebastian. He saw numerous 'tunnels' fly past him and had to concentrate, waiting for the right one to approach. He knew what he was looking for, finding it was a different story.
