~Mabel's POV~

I got lost, fast.

I thought I knew the woods well enough, but without the Mystery Shack standing, I had no way which direction was which.

My legs grew tired and my throat went dry. I found a creek and took a long drink, resting there for a while. Maybe the portal closed, I thought.

I took another quick drink and followed the creek to the right. I walked for about fifteen minutes or so and stumbled into town. It was an exact replica of Gravity Falls. I spotted a blond girl about my age, sitting on a park bench, wearing all black despite the heat. Pacifica?

I walked over to her. She had a solemn look on her face and wore no make up. Okay, this is weird even for an alternate dimension.

I tapped her shoulder. "Um, could you tell me-"

"Mabel!" Pacifica practically screamed. "Y-your alive?" She pulled me into a hug. I froze. "Uh..."

"No," Pacifica said. "Oh course you're not her." She let go and slumped down on the bench again, covering her face. "She's dead. And so is D-Dipper." She started to sob.

I touched her shoulder. "Hey," I said. "Shhh, its okay-"

"No, it's not!" She yelled, sobbing harder. "They...they were my best friends and then Dipper w-went crazy. H-he killed Mabel and Stan." She sobbed. I let her.

A minute later, she sat, breathing heavily. "I-I'm sorry."

"I understand."

"You just look so much like her."

"Well..." I said, deciding it would be best not to tell her that I was Mabel, but from a different dimension. I didn't want her to this I was a weirdo or anything. I cleared my throat. "I'm...Carol."

Pacifica smiled slightly and held out her hand. "Pacifica."

We shook hands.

"So," Pacifica started, wiping her eyes. "Where are you from."

"Uh, Idaho."

"Cool," Pacifica said, although I could tell she was just being nice.

"So...where do you live?" I asked.

Pacifica pointed to a smallish-biggish house on the end of the street. "My mom and dad own the bakery downtown."

Bakery? What happened to their mansion and not having to work?

"So, where are you staying?"

"Uh, with my Great Uncle...uh...Bob. He lives just outside of town."

Pacifica nodded. "Well, it was nice to meet you, Carol."

I smiled. "You too."

She stood up and walked back towards her parents bakery. "Weird," I muttered.

~Dipper's POV~

You know that saying, Keep your friends close and your enemies closer? Well, how close do you keep the demonic alternate version of you which isn't exactly your friend but you're not enemy either? Well, at the moment we were holding tightly onto each other for dear life, plunging to our deaths.

We stopped just before we hit the ground. I looked down to see myself floating just off the ground. I glanced at the alternate version of myself. He was chewing his lip. What?

I wish I was human.

If you were human, you'd be dead right now.

I know.

Before I could even process what he was getting at, we were yanked up again, finding ourselves in the clutches of the two Bills. We both sighed at the same time.

"I think that's enough for today," the alternate Bill said.

"Don't want to wear them out too fast. We've still got a lot of training to finish."

"Hopefully you'll be back in your own dimension by then."

"I told you, this is all your fault!"

They went on like that for a while. Then we went back to our "room". It was actually closer to a cell in my opinion. Alternet me sat staring at the floor, his head rested on his hands and his elbows balanced on his knees. I thought about what he said. I walked over and sat next to him. We sat in awkward silence for a few minutes. "You okay?" I asked.

Wrong thing to ask. The poor guy buried his head in his hands and broke out into sobs. "This is all just s-so stupid!"

I wanted to comfort him, but I didn't know how. How would I comfort myself?

You'd change the subject.

Telepathy. Can be irritating.

"D-don't change the subject," Dipper said. He took a shaky breath. "I need to get all this...this guilt off my chest."

I listened patiently as he told me his story.

"About a year ago, mom and dad sent us off to Gravity Falls. It was fun, but there seemed to always be this feeling of being watched. No one believed me. Then I found this journal..." He reached under his pillow and brought out a very familiar journal. The same one Bill had thrown into the portal. Except the book was blue. "It confirmed all my suspicions. About a week after I found this journal, Bill visited me. He told me that he would help me figure out all the answers. He said the price was that I'd give him a place to live in the back of my brain. 'Won't even know I'm there' he said.

"I didn't know anything, so I said yes. Mabel..." He choked on her name. He closed his eyes and took a deep breath. "Mabel noticed my strange behavior before I did. I become more reckless, talked more openly, became some sort of stalker, you know, that kind of things. She simply thought that I wasn't getting enough sleep, which was also true, I guess. But it wasn't until Bill had whispered in my ear, 'Wanna have some fun, Pine Tree?' and had forced me to grab a knife and hold it above Mabel's bed, that I noticed that letting Bill into my head had been the worst mistake of my life.

"Stan threatened to send me to a mental hospital. Mabel had begged him not to. I was so scared of what Bill would make my do that I almost agreed with him. But I didn't want to. I was too selfish and let Mabel wiggle me out of it. The night Mabel had saved my hide, Bill told me to kill her. I was able to say no for three weeks. But when those three weeks ended, Bill had changed all my happy childhood memories into the worst memories in the world, always me being the good one and Mabel pretty much being the evil twin. Like the time that we were having a war with squirt guns when we were eight, he turned me into the victim hiding from her firing a real gun at me but never hitting me.

"Anyway, that was the night that I'd taken a knife and sharpened it. It was about one in the morning when I stood a over her, with the knife raised and...and..." Dipper broke down sobbing again. I patted his back awkwardly. After a few minutes he whispered, "The next morning her blood stained my hands and clothes." He cleared his throat and wiped his eyes. "After I saw what I did, I cried. Cried in sorrow grief, exhaustion and pure fear. Fear of myself...

"Anyway, Stan came in and that's when my memories get a little fuzzy. I vaguely remember a fire and becoming a demon, but it wasn't until I saw your sister in that hospital room-"

"Hospital room?" I interrupted. "What hospital room?"

"When she came through the portal, she broke her arm," Dipper said with a shrug. Bill brought her here to try and make me kill her too. But don't worry, I would never do it again if you held a gun to my head."

I remembered my hands grasping Mabel's neck. Fear crept into me. "W-what if Bill makes me kill her? You saw what I did back there. I almost choked her and I barely remember doing that! What if-"

"Hey," Dipper said. "We'll get ourselves free before then. Don't worry."

I swallowed, not so sure that would be our decision.

A/N:
Okay, I have a good reason for this being such a late update!
I was in the car for 21 hours, was in North Carolina for three days without wifi (well, exept for like a total of 24 or so hours when I was at our "hotel", but I was probably sleeping at that time)

Now, I finished this up in yet another 21 hour drive, without wifi, hoping to get home fast so I can share this portion of the story with all my patient readers who haven't given up on me yet!

Hope you like the update. I think I've got an idea of how I'm going to make the rest of this story go, so hopefully these updates come more frequently!
