Dipper and Mable were walking through the forest.
Dipper had his nose buried in his book, and Mable was skipping along. Dipper smiled, "Aha!"
Mable peered over his shoulder, "What Dip-stick?"
"There is supposed to be some sort of portal somewhere-" Dipper was cut off by Mable, who started running in the direction of where the journal said to go.
"Then come on!"
Dipper groaned, and ran after her.
Dipper's P.O.V
We came to a clearing, where a white slap of stone sat. Vines covered it, and small carvings were etched into the side. I knelt down to examine them, curious, when it lit up with a glow.
Mable and I stumbled back as the light turned into a beacon, flowing up into the heavens.
I could make out three forms in the light, floating. The light slowly diminished, and I started to move forward again. Mable grabbed my arm, and I looked back to see worry outlining her features. I nodded, and she let go.
Slowly, I approached, just as the figures fell to the ground. Only one seemed to be unconscious. The other two were trying to hoist him up, muttering things under their breath.
One raised a hand and brought it down, slapping the other guy across the cheek. The person sat up, rubbing their cheek, and looked around.
"Where are we?" he asked, an accent apparent. He pointed at Mable and I, "Who are they?"
The two others turned to look at us, questioning looks being used. They were all guys, and looked to be around my own age: 12.
The first had raven black hair that was rather poofy, yet silky. He had chocolate brown eyes that peered at me from behind square-rimmed glasses, and a set jaw. He was rather fit, and had on jeans, a red checkered shirt, and wore pink headphones around his neck.
Mable squealed, as this is what she would classify as 'hot'.
The second was skinny, less fit then the other, but looked respectably strong. He had bright blue eyes, and light brown hair. I was surprised to see some gray mixed into his hair; his gray cap had hidden some. He also had headphones, but they were green, and had eyes on them. He wore a blue hoodie and some jeans.
The one that was on the floor had stood up.
He had sandy blond hair, and bright blue eyes, full of life and wonder. He seemed a little scrawny, like myself. He seemed taller than the others, and lanky. He also had headphones, but they were blue. He had on a simple white shirt and jeans.
I cast a glance at an excited Mable, and grabbed her shoulder, keeping her from freaking them out. I finally spoke, "Who are you?"
"Well, same question goes for you." the black-haired one responded in a really deep voice. "But sure, we'll tell you. Then we- at least I- want some answers. I'm Mark," he gestured to himself. "That's Sean, but we prefer to call him Jack," the guy with the cap, who I assumed was Jack, narrowed his eyes in a hardened stare.
"And that's Felix, but you can call him Pewds," the sandy haired one bounced up and down slightly, smiling.
"Hey, what's up, bro?!" oh no, another Mable.
"So, answers?" Mark demanded, "Did you kidnap us? Some crazed fan or something?"
"W-What? N-No! You-You came here on that, p-portal!" I stuttered, pointing at the thing under their feet.
Jack, in turn, did a double take of his surroundings. Then he looked at himself, and yelled. "WE'RE KIDS!" I noticed an Irish accent.
"Well, yeah, what do you mean?" I was confused.
Pewds started to hyper-ventilate, "Oh crap, oh crap! What-What about my bros?!"
"And my Markiplites!" Mark called.
"AND MY VIEWERS!" Jack screamed.
I tried to calm them down, "Whoa, just- tell me what's going on." my hat flounced a little.
Mark turned to me, eyes full of worry, "J-Just, tell me where we are, quick!"
"G-Gravity Falls, Oregon,"
"WHAT? THAT ISN'T A PLACE!"
"Well, I-it is..."
Jack ran over to me and grabbed my shoulders, "Are we in the U.S?"
"Yeah..."
"B-But, I-in our world, there is no 'Gravity Falls'!" Mark cried out, "And we're adults!"
"You're from another world?"
"Seemingly so!" Mark ran a hand through his hair. "Can ANYONE get us back?"
"I-I think Great Uncle Ford and I can," I stuttered.
"Good, can ye take us to him?"
"Uh, s-sure...-" I was cut off by Mable.
"YES, YES YOU CAN! COME ON!" she squealed, grabbing Jack and Mark's hands. She started skipping toward the Shack, dreamily staring at the two confused boys. I sighed, and looked at Felix. "Are you anything like her?"
"Er, no,"
"Good, c'mon."
