All of a sudden everything returns. Well, in this case everything is merely awareness of your condition, considering all that's been on your mind for the past eternity or so was blank space within a static half-slumber.
You figure you might as well stand up, walk around, and stretch for a bit, make some use of awaking again. I mean, it doesn't really matter right? Asleep, awake, the end goal is the same. You've accepted this dull fate that your naive and impulsive self accepted long ago.
You open your compartment and walk down the hallway, itself in a cart consisting of three rooms, a bathroom, a dining room(with no food, granted, but you can't starve), and a living space. Such simplicity you've been forced to live inside for near eternity! And on either side of the cart, locked doors leading to other trains carts, which are completely impervious to any sort of pushing, banging, hitting, you name it, you've tried it.
But just as you are about to jump on the one couch and think for a bit, you see a person sitting on it you don't recognize! And he's shaking, clearly scared, and now, looking into your eyes brightening up a little bit. He says:
"You, You woke up! Oh my Gosh. You have no idea how hard I was banging on your door. And you just stood there, lifeless, like the rest of them. God, how do you feel? It's been some time..."
Shocked someone other than your two friends is here, you think for a little. Is this guy good or bad? Clearly this is some abnormality going on here. You thought there was no chance for any change, but if you are ever going to escape this forsaken place, perhaps this guy could be a chance. You respond, defensively "Who are you, and how did you get here"
"My name is James McConner. I'm a fellow redditor, like you I suppose. I clicked yes on this stupid train ride too, as you must have. I actually live one cart down. You're the first cart I came to check on after I figured out how to open the doors. There's something extremely important you need to know"
(Ooohhh something important? And he figured out how to open the doors!) "Same! I thought this was going to be like an extra long vacation. But it seems you just disturbed my eternal peace. So this better be worth it, tell me what's up"(You called it peace? Well, you were always somewhat the optimistic type)"
"Sure, but can I know your name first? I've suffered with blankness and loneliness for so long I need some piece of human sincerity for a change, if nothing else"
"My name is Ellie. Go on with what's important"
"Thanks. Ok, I'll try to be frank. Do you remember what terms of this ride from the reddit post? We are supposed to be here for 947274811005827483005271 years. Clearly it feels longer than what we supposed it would be, huh? Hah(dry laugh). But there was something I dreaded would be the case, so I kept track of time."
"You kept track of time? But how, unless you actually were....NO! YOU DID NOT STAY AWAKE THIS ENTIRE TIME!!"
"Hehe, no actually. See this here? (Points to watch) It beeps loudly every hour. But I was able to hack into its controls and modify it a bit. It now beeps loudly every...40 billion years or so. And after a bit of training of making we awake every time it beeps, I've been falling asleep, and, 40 billion years later, it wakes me back up again. And I scratch a marking on the wall. to mark that much time has passed."
"Wow, very smart of you. But, how long has it been?"
"*dramatically* It has been 947274811005827483005271 years"
"*shocked* "Are you serious? But then... why is the train still moving?"
"*sighs* I'm pretty sure I know. It is what I feared. It was not actually just 947274811005827483005271 years. It was 947274811005827483005271! years. There's an exclamation point at the end. That means its a factorial. In other words, say you have the number 5! . That would be 5*4*3*2*1 or 120. So the real amount of years is, truly, much greater, incomprehensibly greater than what we thought. We were double fooled, hah*said sadly*"
--Yeah I don't read or write much but here is my contribution to the story hahaha. IF there are any plot holes or inconsistencies which ruin it I'm sorry, I lack experience with this sort of thing.
