Hey guys. I will be working on the sequel to the Mystery Kids Series, but this popped into my mind. We all know that the previous episode of Gravity Falls left us on a major cliffhanger, and I hate how we have to wait until summer to see the next episode. Anyways, the previous episode was most likely my favorite of all time. I decided to write a short story if Mabel ended up being sucked into the portal. I literally thought that she was going to,get stuck in the other side of the portal. Anyways, this is Chapter 1, and I'm unsure how many chapters will be in this. It depends. Okay, I know this is dragging but I'll now shut up and let you read. Reviews always welcomed!

Alternate Universe

Chapter 1: A New Universe

Mabel's POV:

"Mabel! Press the red button! Shut it down!" Dipper screamed while pushing his 'Grunkle's' fade away from him so he could speak clearly in a serious tone. Dipper Pines knew that I, his twin sister, didn't shut the portal down like he said to, the world could end, and for all he knew, something horrible (probably even more horrible than Bill Cipher) could emerge from the other side is of Stan's portal.

"NO YOU CAN'T! YOU GOTTA TRUST ME!" Came from my Great Uncle or Grunkle Stan, wailing his arms, begging me not to press the shut down switch. Soos was holding Mr. Pines' body to make him not get close to me since he stated that his new job was protecting me and my brother. Whatever was on the other side of that portal was clearly important to Stan, but Dipper's plead was ringing through my head as well. I stared at all of them, fighting one another while I grasped tightly at the leg of the shut down switch. Seeing my family fight during the possible last few seconds on Earth brought sadness to my system. I didn't know which side to believe, and whichever one I chose, could most likely be the wrong decision. Leave it to a twelve year old girl who likes pigs and sparkles to make a close call decision. I honestly wanted this day to end just how this day began.

"Grunkle Stan, I don't even know...if you're my Grunkle." I blurted out. I looked away, not even daring to look at all three of them. They all knew that the weight was on my shoulders and that I had a really tough choice to make. I was beginning to trust Dipper more than Grunkle Stan. After what me and my brother discovered earlier today, about the robberies and the fake identifications, I was half tempted to push the button. However, trust was a really hard word to identify now when it came to a life threatening situation. I wanted to believe him, but if I did, the world could end. I sob lightly, not hearing the grunts from any of them at the moment. "I wanna believe you but..." but if I don't press the button, the whole world could end, and everyone who we know and love will be gone forever!

"...Then listen to me! Remember this morning when I said I wanted to tell you guys something?" Grunkle Stan replied with concern showing in his voice. I was unable to reply because the computer had given another warning, explaining how much time was left on the clock. The next thing I knew, I felt a powerful force shot out of the portal and pushed Dipper, Stan, and Soos to the wall. The force almost sucked me in, but I had just enough strength to keep me at the shut down switch. I felt more confident listening to my brother than my Grunkle. I mean, yeah he's family, but Dipper is technically my built in best friend and he's given up so much for me. It was time that I gave him something back in return. I clenched my hand, forming it into a fist and I was about to slam it on the button, but Grunkle Stan continued his reply from earlier.

"I wanted to say that you're gonna hear some bad things about me, and some of them are true. But trust me; everything I've worked for, everything I care about...it's all for this family." Those words really struck me...hard too. Was he really working on this machine for our family? Was he really being truthful to me? I was now second guessing my decision, wondering which one I would decide. But whichever one I chose, could be the wrong decision.

"Mabel what if he's lying? This thing could destroy the universe! Listen to your head!" That plead came from Dipper. I didn't bother to look at any of them; my mind was mesmerized by the swirling colors that we're spinning rapidly around the rim of the portal. My brother was certain that Grunkle Stan was lying and that he didn't want me to shut it down for some reason I have yet to hear. However, who knows what could happen if I made the decision to shut it down? Would the universe stay in tact or as life as we knew it would end right underneath the Mystery Shack? This decision was getting harder and harder to choose!

"Look into my eyes, Mabel!" I did, tears still visible on the bridge of my eyes. "Do you really think I'm a bad guy?" That was definitely a tough question now that I thought about it. I knew that he would shoplift the occasional tangerine, but he wasn't some evil super villain. What I saw with Dipper a little while ago in Stan's office made me feel like I didn't know who this man was anymore. But after that one rhetorical question he sent out to me, made me second guess what I was going to pick.

"HE'S LYING! SHUT IT DOWN NOW!" Dipper screamed, practically begging me to listen to him. I looked at him with a "what do I do" expression on my face, and he sent me back a "listen to me, I know that he's not what he seems" look. I heard Grunkle Stan plead once again, as I looked over to him. I was trembling, and my heart was racing a mile a minute. I hated decisions like this because I don't know what the outcome will be like for whichever one I pick. I heard the computer once again, indicating that there was ten seconds left. Ten seconds to make a decision. Ten seconds to either save the world or destroy it. Ten seconds was not enough time for a decision for me.

My hand inched it's way closer to the shut down switch; my eyes closed in the process. I made the decision to listen to my brother, knowing that he knew that if I shut down the device, I will save the world, along with everyone else on it. However, I opened my eyes, and glanced up at Grunkle Stan, one final time. My stomach turn as I saw his expression. It was the "please trust me" look that he hasn't used on me for a long time. Now I was unsure, but I knew time was running out quickly. I looked away with my eyes closed. The next part seemed to happen in slow motion.

"Grunkle Stan...I trust you" I finally let go of the stick from the shut down switch as the zero gravity pulled me up towards the opening of the portal. My hands up in defeat, and eyes closed, knowing that my decision was probably the wrong decision. I heard Dipper screaming at me saying that I was crazy (for choosing to not press the button) and that we're all going to die, but the last word of his sentence got caught off when everything around me turned white. I felt my whole body get sucked into the portal as I heard Dipper, Stan, and Soos screaming, figuring it was the end. However, when I felt Gravity go back into place once again, I opened my eyes and saw a grey sky, along with about forty people dressed in the same battle suits and rifles placed behind their backs. I froze, scared to move even the slightest part of my body because I could die right here. No one spoke a word to me. I moved my eyes, looking at the scenery presented in front of me for a good two minutes, until I saw it. The welcome sign that had spider webs and pieces of rotting wood falling to the ground look exactly the same as the one in Gravity Falls.

The only difference? I wasn't in Gravity Falls anymore.

This concludes Chapter 1! I hope you enjoyed.

Question: What do you think the name should be for the town Mabel is now trapped in? Please leave your answer in the reviews. Thanks for reading!
