Chapter 10 The Plan

Vampire Bella's POV

I hated to think that the Edward I feel in love with had to be killed. I know the Doctor kept saying that the world could not support two timelines, but I had no idea what he meant by that. It sounded like the world would be destroyed, but there was no evidence of any harm to the planet from the last thousand years.

"Doctor, you keep saying that the timeline shouldn't have fractured, but it did. So what do you think will happen and why has it been a thousand years and nothing is wrong?"

"Well in truth, I am a little puzzled by that myself. What I fear is when it happens it will be big, cataclysmic big. Like a volcano that keeps building and keeps building until it blows its top, like a super volcano. I have experienced a rift between parallel worlds before. The temperature of the planets was growing out of control and the planet was going to rip itself apart. By all accounts it seems that what is happening here is that the pressure is building and when it breaks the world will be ripped apart, earth-shattering earthquakes, volcanoes and storms that will never end, eventually making the planet uninhabitable."

"Sounds a little apocalyptic don't you think?"

The Doctor rubbed his face and looked down, "It is. There seems to be no escape for the pressure that is building. I would venture to guess the world has swelled to a larger size somehow. What is happening is two objects of the same mass are trying to occupy the same area, though they are just out of sync. It would be like déjà vu, something happens in Edward's timeline and the same thing would happen in your timeline a moment later. Basically the time it took the Angel to touch you is how far apart the timelines are."

"So because the Angel touched me, in the time it had its hand on me the world was shifted. Since I didn't die that shift was never corrected. Because that shift has been building for the last thousand years the world might end?"

"That sums it up. It would seem the pressure build up is very slow, so there have been no ruptures like I thought there would have been. Who knows maybe if I do a survey of the planet I'll find major changes all over, like temperature rises of the oceans and rivers, and vast amounts of water evaporating globally. A climate shift like global warming, hotter summers, colder winters, with less mild climates between seasons."

"It sounds too unreal. I am having a hard time understanding the world could end because of a timeline change. I know I was supposed to die, but I still can't understand how the world would end because I didn't die?"

"Simply because the world has to support two timelines now, your human timeline has caused it to split. You see when you went back-in-time, as far as the world is concerned, time would have started over. In your original timeline you went to your past and changed history. To most people it would make more sense that you are the one that caused the split and in a way that is true. However, it was Edward's inability to let go of you that caused the changes. I guess it would be fair to say that both of you had a hand in reshaping the world."

"So my going back in time would not have affected the normal flow of time?"

"No, time is always in flux, but it is linear from the Universe's point of view. While there can be parallel worlds those are sealed off and it is very bad to try and go between those. When you went back in time, as far as the planet was concerned it was 1917 and moved forward. In 2005, where you left hadn't happened yet, even though there were people that knew you suddenly disappeared they would have died without knowing the truth. Since the ones that knew you were immortals they lived beyond the normal flow of time, thus creating a split in the timeline. As I mentioned earlier, only the people that you knew where initially affected. Since that scope would have been small on the overall global scale nothing bad would ever occur. However, one of the people affected was an immortal vampire and over time your loss influenced more and more people, globally."

"OK, since I was supposed to be dead in 2005 but continued on, my timeline would have been the new timeline. The timeline that I left was supposed to pretty much end with the death of those that knew me before I disappeared?" I was starting to understand, a little, but time travel was really a difficult concept.

"Exactly. Since you could not have had a global impact from your human life the world would have been reset to the normal flow of time, like it is in this time period."

"But the humans know about us in this time period too. You said that you had never met a vampire before me. So wouldn't we have changed the course of human history?"

"Yes and no, everything can influence the future. Very few things can alter it. The arrival of alien life on the planet happened a very long time ago, but no one knows it. It changed the way a lot of governments operate and also forced them to take measures in case other alien life came to the planet. That event influenced the future. Now what if that arrival of alien life was made public and the world's governments announced that 'we are not alone'. That event would have altered human history."

"I see your point. Since Edward lived through the heartbreak of my disappearance he sought escape. When he found what he was looking for he influenced powerful being to change their view point of their way of life. After that the powerful beings changed the course of human history by taking over and ruling the human world from the shadows. It would be a safe bet that in another thousand years the vampires are the public rulers of the world and the human farms are the norm for a human's way of life."

"Precisely, if Edward had died at that age of a normal human's death he would not have been able to influence the vast shift of human history. Since he did, the timeline that you know was altered and a new timeline was created a timeline that should not exist."

"Is there any way to correct it without killing?" I really did not like this new Edward, he was cold and distant. The only problem was it was the Edward I fell in love with, the first time. I couldn't bring myself to end his life.

"Change the past. I think if he could see you, maybe you could convince him to follow a new path. The only problem is there are not two of you. You will always be lost to him. If you stay with this other Edward in the past, the first Edward will most likely end up going down the same path as the Edward we are with did. I am not sure how to keep him from doing what he did. I would guess based on everything he said is that you have a month after you leave before he ends up with the Volturi. While you could prolong that as long as you wanted at some point, when you leave, he will end up back on that same path."

"This is impossible Doctor. I can't pop back in his life only to leave again. I can't even begin to understand what that would be like. When I first arrived in 1917 it was hard, but I was scared and not sure what was going on. After I meet you and realized what had happened I was too stunned to really comprehend everything. Before I was able to come to terms with the loss of Edward I found a human Edward and fell in love with him all over again."

I was taking unnecessary breathes at this point. It felt like I was going to hyperventilate at any moment, even though that was impossible. My mind was going faster than ever before, thinking of plans and rejecting them just as fast. Everything I wanted to do would not be feasible. As the Doctor said there are not two of me. Even if there were that would mean pulling a me from a different timeline. Ending a relationship early or not even…

"Doctor, what about if we don't focus on Edward, but me?"

"We did go over this, while it is true that you are the cause in some small way it is Edward that ultimately lived beyond the time frame the world could maintain the single timeline."

"No, I know that. What I am saying is we focus on the me before I meet Edward."

"That won't work. If you don't meet Edward and go to the garden then you won't go back in time to meet the other Edward. You could do it, not meet Edward, ever, if you wanted to give him up."

That would definitely not work. I must have made a weird face because the Doctor was laughing at me.

"Well then, if we have to wait until after I am sent back, before seeing Edward again, what would be the best way to keep him from going to the Volturi, other than having me stay with him?"

"I don't know him very well. I have only met this Edward that lost you a thousand years ago. What do you think would be best to keep him with his family after he lost you?"

"Finding me again." I knew that was the only way. He was as much in love with me as I was with him at that point. The only way he would not seek an escape is if I was with him. But I can't be with that Edward and meet Edward in 1917 and be with him too. I could be with him for a little while, now. But I don't know if that would help or hurt. The 1917 Edward is most likely dealing with a 2005 Isabella. I would venture to say he is a little freaked out right about now, seeing a human me in 2005 when the vampire me left him in 2002. I really wish I could go hold him, love him and let him comfort me right now. I miss his touch. "What if I stopped the Angel from touching this Bella, the Bella that is in 2005 now?"

"That would be a Paradox, so it can't be done." The Doctor said. I looked at him like he was on drugs. "A Paradox would be like you going back in time to kill your grandmother before your mother was born. If you kill your grandmother you would never be born therefore how would you be able to kill your grandmother? Time gets confusing when you try and mess with it. Just like there are certain fixed points in time that I can't interfere with, you can't cross your own timeline; it will tear a hole in the fabric of space and time and end up destroying two thirds of the universe."

This was harder than I thought. "So how can we alter Evil Edward's timeline? What would happen to that timeline we just came from?"

"Disappear; it would be back to normal, just as if it never happened. He is the cause of the timeline fracture. We can alter his past to set the future right."

"Set the future right?" So if his future is wrong and Aro wanted to take control of the world, by any means necessary, that would mean that the Aro of Edward's time had kill Didyme and Marcus never found out about it. It isn't Edward we have to kill it is Aro. "Doctor I got it. The answer is simple. We do to Edward's timeline what was done to this one. We let Marcus have his revenge for the death of his mate. We let Marcus kill Aro and take over as the Volturi leader. That way Aro will not have power hungry obsessions like the Vampire Mayor had and the world would continue on just as this one has."

"That would certainly work. We need to root out the cause of the alteration and there are in fact two causes, Edward and Aro. If we allow Marcus his vengeance then Aro could not change the course of humanity for his own gain." The Doctor started running.

"Where are we going?" I asked, easily keeping up with him.

"Back to the TARDIS."

"You do realize it is over a hundred miles away don't you?" He stopped dead in his tracks.

"That far huh?" I nodded. "Guess I'll need a lift getting back than won't I?"

I pulled him on my back and ran back to the TARDIS. He quickly unlocked it and ran up to the controls and started pushing buttons. The TARDIS sprang to life again.

"Here we go. So we need to go to the early 21st century, when Marcus learned of his brother's betrayal."

"You do realize finding the vampire that Marcus was referring to will be like looking for a needle in a haystack the size of the planet."

"Nope, we have a secret weapon."

"What is that?"

"Me." He said all smiles. When he had this sort of confidence it was hard to think he couldn't pull it off.

"All right, so where to first? I would dare say we not get involved with the Volturi at this point. We would need to find a way to find the one that knows and keep a low profile doing it."

"True, but we do have friends that will help us." The TARDIS was shaking violently again and I knew we were going back to the other timeline, the one where I was dead.

"My family." I breathed out.

"Yes, you have already disappeared by now. I am sure Edward will be close to leaving, so we need to hurry. There is one small problem with this plan though." He looked sad I knew why.

"I have to die, in front of them. That will give them the closure they need and if Aro is dead even with Edward's immortality it will be enough to keep the human timeline where it needs to be."

"I'm sorry, but on the bright side they will at least be able to say their goodbyes this time and have closure."

I suppose that was the best I could hope for. This timeline Bella is dead and she can't come back. I started pushing buttons and turning knobs and the TARDIS instantly smoothed out.

"How did you do that?"

"What, be a better driver than you? It really isn't that hard, you suck."

We laughed out loud until the TARDIS came to a rest, in Forks, Washington, shortly after I disappeared.
