For an Eternity

"Oh no, what happened to him???" You whimpered.
"OH NOTHING MUCH, I JUST GOT A LITTLE MAD THAT HE TRIED TO TAKE YOU AWAY FROM ME SO I OBLITERATED HIM."
"B-But he was your last hope in finding the equation to get out of here..."
"NO, YOU ARE!"
"How am I your last hope? I don't even know how an equation to the universe or whatever would look like..."
"I'M GOING TO BE HONEST RIGHT NOW. I DON'T CARE IF I CAN'T GET OUT OF HERE."
"Huh??? Why? The whole reason you kidnapped me and Dipper was for the specific reason of getting out of Gravity Falls!"
"IT DOESN'T MATTER WHERE I AM. THE...AH GEEZ, THIS SOUNDS CHEESY, BUT IT'S TRUE."
"What's true?"
"ALRIGHT, BUT DON'T GET MAD AT ME, IT'S NOT MY FAULT YOU HUMANS USED THIS PHRASE SO MUCH."
"Uh, ok, what is it?"
"I DON'T CARE WHERE I AM, AS LONG AS IT'S WITH YOU."
"What?!?"
"I TOLD YOU IT SOUNDED CHEESY, BUT IT'S TRUE."
"I...Um, why do you like me? Aren't I just a stupid little human to you?"
"NO, NO, YOU'RE MORE THAN THAT, YOU'RE EXTRAORDINARY. YOUR SOUL IS A LOT LIKE MINE, IT'S JUST THAT YOU TAKE THE SHAPE OF A HUMAN."
"You have a soul??? Doesn't seem like it."
"LOOK, IF YOU'RE TRYING TO POINT OUT THAT I'M HEARTLESS, YOU'RE RIGHT, I DON'T HAVE ANY HUMAN ORGANS. UGH, HONESTLY, YOU PEOPLE DON'T GET ANYTHING RIGHT. SAYING YOU DON'T HAVE A SOUL JUST MEANS YOU DON'T HAVE THE SPECIAL THING THAT MAKES YOU ALIVE AND CONTROL YOUR BODY."
"God, this is a train wreck... None of this makes sense, what happened to Izzy? Jesus Christ, I have never been more confused..." You said, putting your hands to your head.
"IZZY'S DEAD." He replied.
You stared at the floor in silence.
"Are we the only ones in Gravity Falls?" You asked.
"THE ONLY ONES THAT ARE ALIVE, YES."
"Ok, but everyone else is alive. Can't I just travel out of here and live in New York or something?"
"NOPE, IF I'M STUCK HERE, SO ARE YOU. YOU BELONG TO ME, YOU'RE A PART OF ME."
"Hm. So do I ever die?"
"NOT WITHOUT MY PERMISSION."
"Wow, so I'm stuck with you for eternity? Man, this will suck."
"I KNOW THIS IS ACTUALLY WHAT YOU WANTED."
"What?!?N-No it isn't! I didn't want anyone to die! Oh God... I can't believe Izzy and Dipper and everyone else is dead."
"WELL, IN THIS DIMENSION, THEY ARE, BUT THERE ARE MILLIONS OF OTHER PINETREES AND IZZYS."
"Oh, so there's more than one of you?"
"NO, I'M THE ONLY BILL CIPHER, HAHA, I'M SPECIAL!"
"Ohhhh, I wonder what it'd be like to meet myself."
"LIKE I TOLD YOU, YOU AND ME ARE ALIKE, THERE IS ONLY ONE OF YOU."
"Really?"
"YEP."
He said. You sigh and lie down again.
Somewhere out there, somewhere far from here, Dipper was happy and well. Living with his sister. Maybe he was even dating Izzy, who knows. There were infinite possibilities.
Except for you, there was only one possibility for you, and Bill... If you died, that'd be the end of it, nothing else.

"So, what should we do, Bill?"
"I DON'T KNOW, (y/n),BUT WE HAVE AN ETERNITY TO THINK ABOUT IT."
You laughed and laid back down.
"That's a long time."
