Alone

Chapter 1

Mabel's POV

*BOOM*

A loud explosion sent me flying into a nearby wall.

"Ahg," I groaned as my head and back collided with the solid brick ad fell to the ground with a thud. I was in the Fearamid with Dipper running from Bill.

"Come on Mabel," he ran over and pulled me to my feet. We kept running, and needing to escape Bill and get back to the Stan's, who were currently trapped in a cage by the evil demon chasing us.

"Dipper," I grabbed his had and pulled him out of the way of another blast. We turned around and covered our heads when it hit the wall next to us. "This way," I ran into another hallway. The plan was to turn as many times into different rooms and halls to try and lose Bill. However, that plan didn't account for getting lost. 

"Mabel, do you know where we're going?"

"Uhh," I stopped and looked around.

"GET BACK HERE YOU LITTLE BRATS!" We whipped our heads around. Bill was closing in on us, fast.

"Duck!" We jumped out of the way and ran past him.

"Come on!" Dipper grabbed my hand and we kept running until we eventually got back to the Stan's.

"Grunkle Ford! Grunkel Stan!" I shouted and ran towards the cage.

"Hurry Grunkel Ford! How do we get you out?" Dipper tried to pull on the cage with no luck.

"You can't break it," he hung his head low. "We've already tried."

"Then what are we suppose to do," Dipper let go of the bars.

"I don't know," he picked his head up and hit the bar with his fist. "Bill said he'd let us go if I told him the equation to break down the barrier around Gravity Falls, but I don't know it! I couldn't figure it out." He said the last part in a quiet defeat. Wait! 

"Grunkle Ford! I know the equation!" I ran to the cage and stood across from him with the bars in-between.

"What! how?"

"Well, one day I was walking in the woods, and I heard some gnomes talking about it!"

"Mabel, I-I, I don't know what to do."

"What do you mean Ford?" Stan butted in

"We can't just give Bill the equation, he'll take over the world!"

"But what other choice do we h-"

"TIMES UP!" We all spun our heads around to see a very angry Bill flying at us. He landed directly in front of me. "Give me the equation or watch your family die," He reached out and grabbed my throat.

"Mabel! Let her go!" he ran forward to try to save me, only to get thrown back by a blast of fire.

"Dipper!" I tried to call out, but his hand was cutting off my air. He lifted me off the ground by my neck so my feet were a few inches in the air.

"I'm done playing games Shootingstar! Let me in to your head now or they will all die!"

"O-k-k-a-y" I tried to strangle out. He let go and I dropped to the ground, panting for air. 

"So we have a deal?" He held out his hand, with a smirk on his face. I turned my head to look at Ford. I knew he had the memory gun. I just hoped he was thinking what I was thinking. I knew he was though, by the mix of triumph and sorrow on his face.

"Deal." I turned my head back and held my hand out, which he eagerly took. He laughed as he started to glow blue, and get sucked into my mind. I knew what was about to happen, and I was okay with it. It was the only way to save the world. So I closed my eyes, and made sure my last thoughts were about Dipper. 

Dipper's POV

I pushed myself up off the ground after Bill threw me. 

"Ahg," I stumbled a bit but regained my strength and ran over to Mabel. Wait, what- "Grunkel Ford! Mabel, Is-is, whats going on?" He didn't reply, he just pulled something out of his pocket. Wait, thats a gun! No, It's the memory gun. Then the plan clicked in my mind. "No! You can't do this!" I tried to grab the gun from Ford, only to be held back by Stan. "No! Let me go! You can't do this!"

"Kid, its going to be okay!" He tried to reassure me but I could here the pain in his voice.

"No," I stopped struggling.

"This was her choice. She's saving us." I went limp and Stan let go. I dropped to the ground and watched as Ford typed something into the memory gun and aim it at Mabel's forehead. Then, with one click, I saw a flash of white. When the brightness was gone, I saw Mabel on the ground, slowly regaining conciseness. 

"Mabel!" I jumped up and ran to her "Mabel are you okay?" Her eyes opened and she slowly sat up, using me as a crutch.

"Yeah Dipper, I'm alright." I gasped

"W-what did you say?"

"I'm okay Dipper. Really. I mean, my head hurts a little, but other then that-" she was cut off as I jumped into her and threw my arms around her. 

"Oh my god, you remember me. You remember!" I let go and looked at her, watching her face as it clicked in her head.

"I remember?" she looked at me. "I remember! But how?"

"I don't care!" I hugged her again and then helped her to stand up. 

"I don't believe it." said Ford, staring at the gun in his hands.

"How is this even possible?" Mabel asked him.

"I'm not sure, we should probably run a few tests to make sure he's gone. But if my theory is correct, Bill is gone forever."

"Yes!" I jumped up with Mabel and she laughed.

"Come on Dip Dot, lets go home." she smiled, and we made our way back to the shack.

Once we got back, Stan went out to look for survivors and help organize the townsfolk to clean up and make sure everyone was okay. 

Meanwhile, Ford, Mabel, and I sat in the lab. Mabel was hooked up to all sorts of weird machines. Ford was running the tests to make sure Bill was really gone. 

He explained his theory to me, but it didn't make a lot of sense. He said that Bill was the dominant thought in her mind at the time the memory gun hit her, so the energy and force was used up when it erased Bill. So basically, Bill was almost like a shield to her memory. 

Part of the theory made sense to me, especially when I looked over some of his calculations based on the memory gun's power and Bill's power. But part of it didn't make sense to me. Like something wasn't right, or we were missing somehow. But I brushed that feeling off. Bill was gone and I still had Mabel with me. Everything was going to be okay.

"Okay," Ford was unhooking Mabel from the various machines. "I found no traces of Bill in your mind, except your memories of him."

"What does that mean?" Mabel asked, jumping off the chair she was in.

"He's gone. For good." I looked at Mabel who smiled and me. We were free from Bill.

...For good
