"Who are you? You aren't Red."
Of course he wasn't Red! He'd been saying this for what felt like forever, but no one ever listened. It was as if there was some extravagant sign above his head proclaiming "I am Red!" To be honest, he wasn't even sure who Red was.
Over time, however, he began to piece together just who "Red" was. He was the person Fire was supposed to be. He was Green's rival. He was a great trainer. He may or may not have looked exactly like Fire (depending on who he spoke with, the information differed).
Fire was the fake. This wasn't his story. He walked in the footsteps of this "Red", doing everything the same. All he was doing was following. This was Red's story, and yet it was the repetition of something that had happened once before.
"You appear to be very gifted as a Pokemon trainer. Not as gifted as he was, though."
Fire was supposed to be Red, but somewhere things had been messed up. Though he did everything the same, there were flaws. He didn't look the same, he didn't react the same, he wasn't as good. He was an imperfect copy.
"You're no one."
"This isn't right."
"Please don't come back."
He wasn't going to come back.
This "Red" guy still existed, right? All Fire had to do was find that asshole and send him back. Tell him about all the people, all the signs, everything that begged and pleaded "Come home".
Or he could just punch the guy for ruining his life, "his story", before it even began.
