"The deals off Bill." Mabel says, glaring at him.'

Bill snickers. "I don't think you get it, you can't take this deal back."

"Too bad! I'm doing that right now!" I yell back.

He immediately stops laughing and glares at me, furious. I nervously laughs and take a step back. A red fireball appears floating above his hand, slowly growing.

I turn around and start sprinting toward the strange black shadow that had appeared earlier, grabbing Dipper's hand on the way.

"Mabel! What are you doing?!" Dipper panics, obviously not wanting to go near the shadow

"We don't have much of a choice, now do we?" I continue to run, and I pass through the shadow, but nothing changes except the fact that I can't see. I continue to run until I find a window, picking up a random object around me and smashing the glass. Once I think I've smashed all the glass, I jump through the window, making sure Dippers following, then continue to sprint.

"Do you wen know where we're going?" I hear Dipper say from somewhere behind me. I look around, seeing nothing but darkness all around me.

"No, no I don't!" I reply.

"Great." He sighs.

"Do you have any better ideas?" I ask, almost tripping over something

"No, but it would be smart to remember what direction the shack is from that store." Dipper says

"I'm pretty sure I'm headed in the right direction..." I start. "But I'm not entirely sure.."

"Well let's just hope that you're right." Dipper says.

We continue to run through the darkness for what feels like hours, having no idea where we are. I suddenly stop. "This is impossible!" I sigh in frustration.

"How long have we been running?" Dipper asks.

"I don't know." I sigh. "But we have to be close, right?"

A reddish orange flash appears in the distance, but close enough that we know where it is.

"What was that..?" Dipper asks, both of us look in the direction the flash came from, some of the red and orange still left over, the rim of the reds and orange outlined in yellow.

"Let's go." I start to sprint toward the red light and know Dipper is following me. We run for a few more minutes until we eventually break through the darkness, standing in front of the Mystery Shack

My eyes well up with tears and I collapse onto my knees, crying.
Dipper stands there, shocked as the Mystery Shack is consumed by flames.

"W-what?" He whispers.
Firefighters were already there, the trying to put out the fire that had erupted from our home.

I look up and see Bill floating above the Mystery Shack, grinning, but when I blink, he's gone, disappearing without a trace.

-------Epilogue------
(Yep, that's right. We've already reached the final chapter.)

It's only a year later and me and I'm sitting on the roof of he mystery shack, on that small balcony-like place where we used to slack off with Wendy.

The shack wasn't too damaged from the fire, but the basement, along with the portal and all the machinery, had been completely burned, nothing remaining.
We haven't seen Bill since that day, and frankly, I'm happy about that, but I wonder if Dipper is, he's still mad at Bill and wants the journals back.

I sigh, hanging my legs off the side of the roof. After the fire, Dipper had finally told me that Stan was currently in a retiring home and he had been for a while, about 5 years after I disappeared he couldn't take it anymore and decided to retire. I've visited him a lot since that day, you should've seen the look on his face when he realized I was back. He's still the same Stan I remember, he plays cards with the other old people and always wins, by cheating of course. So nothing much has changed with him.

Dipper on the other hand has taken up a task of writing a new set of journals himself, which to my annoyance he won't let me help with. I wonder if in the future some 12 year old kid will find his journals and get obsessed with he paranormal. I sure hope so.

And if you're asking, yes, it does bother me that I missed all those years of my life, but really, it's no big deal. It's not like I can go back anyway now that the portals destroyed.

Sometimes I wonder if Bill will ever come back, but then again, if he does, then I guarantee that I'll punch him.
That evil dorito is definitely what's responsible for destroying part of the shack. And if he ever dares to come back to Gravity Falls then he's definitely going to pay for what he's done, both me and Dipper can promise that.
