"Well I assume you wanted to know how I got here" I said to myself looking at the red unicorn with a PI sign as a cutie mark; "We find the key?" I ask him er me with what I assume must have been a very quizzical look on my face. "Yes we do Cool Mint we find the key it was looking right at us right at you for now I know what you don't we can change everything, and It was all so simple" I was confused as I looked at myself I wondered why if all places to travel to did he come here why did he want to visit me er himself I guess perhaps he didn't want to ruin a time line or maybe the time he tried to travel was the same time I would be here? Though if that was the case what of the future what happened how did we get to this moment? My head begins to ache as I look at myself "So the key what is it?" he asked looking at me with those blue eye's "It's PI" I reply looking at him and the device sitting on the table we could never figure it out, multiple time lines ended in failure; it asked for a key a password, six letters or numbers or a combination of them along with symbols that would allow me or I guess now us to travel.
Where would we go, we had no idea, I now knew though we would return here about five minutes before said events even started; "wait" I say aloud as the possibilities flow through my mind like a pie being cut indefinitely "what happens if it does work?" I began to see his reasoning immediately after he uttered the words, what happens if it works? there are two of us here now and I have no way of returning to my own time now once I traveled the machine stayed in the time I came from but now I've created a new time line since 3.1415 was the password I would give him or in this case my own self who is not me anymore information that doesn't exist yet would make us both witness what happens next, what I already know, then how do I get out of this? I watched myself debate internally he seemed to understand my our situation as of right now we know what the outcome will probably be as we can understand it. A loop, would be unacceptable due to it being counter productive to our cause if I simply went along with what he said and not considered the consequences of traveling to a point in time in which I or we know the outcome could it really be that simple we just stay like this until one of us uses the device to travel or we get hungry and leave for food how would we explain ourselves?
I assume that we could claim that he is clone for a while, but what happens when the trip is over does he return to where he last left I look at myself once more. It would seem that with the knowledge we both have that the situation here is as plain as day; we will not cause anymore distress to our universes we will figure out how to stop this from happening if it is only for the sake of ourselves; the stallion in front of me who is and isn't me seemed to figure out the consequence in a flash. "I must say that was very quick thinking imagine what would have happened if we had just looped over and over again" I say to myself laughing at the notion of us having caused so many loops that our or his home would have been overrun with other versions of himself all telling him the same exact information or perhaps joining the debate of constant looping until we find the solution. "Yes that would have been a terrible endeavor indeed, so the only question is how do we deal with this problem?" I ask looking at myself who now has a worried expression on his face, "well I only see a very tiresome outcome don't you?" I ask myself who by now knows all too well what it is that I'm implying. "You can't just, look even if that's a possibility then what, you live as if nothing has happened" I can see the worry in his eye's he seems to still think that since he is me I will not use a more interesting approach to our problem; the solution is an easy one once you realize that you aren't looking at yourself anymore I realize that now he isn't me I'm me and no one else is the solution to the problem is simple all I have to do is wait.
At the very start the solution was clear PI or perhaps pie was the only clue I needed to solve this puzzle it was as the me had stated before the solution was right in front of us but his interpretation of PI was PI while mine is pie. We had to solve this problem but our vision of PI made us realize that we had conflicting viewpoints. This must have occurred when he traveled here after finding his solution to his version of the device; when he traveled to my time it must have caused a change in my own personality due to his interference with our time line. He was the problem not me he found the code to use the device, the key which to our dismay was the one and only solution which paradoxically must have been the reason why the device was given such a code. PI connected everything and every version of myself, in this case it would seem that if my future self had not figured out the entire rationalization of our cutie mark PI and the device we would have never known about any of this. Though it could have been that his time line was changed by a force or ponies from yet another universe or time line that caused some sort of shuffle in which time changed to allow an unsolvable code that could be solved.
Alternatively it could also have shuffled events that allowed my other self to come to the conclusion that would allow all of these events to take place in that case he is nothing but a pie that was left to cool outside. He has become his own problem by finding the very code who's clue was our very own cutie marks.
3.1415 is the key to our solution our salvation and our destruction as all lines converge with ours we see the truth in all things I thought as I ate my cheery pie.
