Shingeki no Gravity Falls - Part One

“I will kill... Every...”  Eren tossed and mumbled in his sleep, a green leaf sticking to his cheek.  “Last...”  He snored.  “Eren!  Wake up!”  Armin shook his friend.  “Agh!”  Eren jumped up and started to reach for his twin swords out of habit but he found that they weren’t there.  “Where are we?”  Mikasa asked, standing up.  Armin shrugged, Eren rubbed his eyes.”  Mikasa readjusted the red scarf around her neck as Eren stood next to her.  “Mabel, come on!  I swear I saw the light flashing just a little further up there.”  The Shiganshina trio turned towards the voice to see two kids in strange clothes stepping through the trees.  The kids looked to be a bout twelve or thirteen, a boy and a girl.  The boy was studying a page in an old book and the girl rolled her eyes.  The boy looked up and his eyes widened.  Armin raised his hand and waved awkwardly.  “Uh, hi?”  The boy asked, tucking his book under his arm.  “Oh my gosh, I love your hair!”  The girl skipped towards Armin and batted her eyelashes.  “I’m Mabel!”  The blonde boy chuckled.  “Uh.  I’m Armin, that’s Mikasa and this is Eren.”  Mikasa and Eren mumbled greetings.  The boy introduced himself as Dipper Pines, the girl was apparently his twin sister.  “Do you know where we are?”  Mikasa asked, stone faced, stepping towards the brother and sister.  “This is Gravity Falls, doy!”  Mabel stepped closer to Armin and opened her mouth to speak again when there was a loud flash directly above the group and a scream.  A short guy with black hair fell through the sky followed by a woman with glasses who landed on top of the short one.  “What the?!  Ow!  Hanji!”  The short one screamed and pushed the woman off of him.  “Corporal?”  Eren asked as the trio stood at attention, Mabel blinked, and Dipper flipped frantically through his book.  “Can you tell me what the heck is going on, Jeager?!”  The short guy stood and glared at Eren.  Eren shrugged.  “Aha!”  Dipper jumped and pointed at his book.  “You guys came from a portal to another dimension!”  Mabel took the short guy’s hand as he glared at her.  “Welcome to Gravity Falls, beautiful stranger.  I’m Mabel.”  “Mabel.”  Dipper groaned.  The short guy shook his hand away from hers and looked down.  “Levi.”  He ignored the girl as she continued to stare at him.  “Does anyone know how to get us out of here?”  He looked at Armin.  “Come with us, I think we can reopen the portal tonight, but you can stay at the Shack until then.”  Dipper readjusted his hat and motioned towards the hiking trail.  A look of confusion passed over the group but they followed the boy.
