Who are you?! ((Reversed Falls))

Explanation

I FINALLY have time to update, school has been driving me crazy

---------Mabel Pines' POV----------

"His name is Will, he's kind of like Bill's reversed personality, just like she," I pause for a moment, pointing to the Mabel who was currently tied up. "Is my reversed personality."

"So in this other dimension, there's another Dipper?" Dipper questions.

I nod. "He's really snobby and acts like a total jerk all the time." I huff, crossing my arms.

"Is there another Stan in that dimension?" Grunkle Stan asks after staying silent for a few minutes.

"I never officially met him, but yes."

"So why exactly did Bill swap you two in the first place?" Dipper questions.

"If I knew I  would've told you by now." I sigh, looking at the ground. "What about you guys?" I ask, looking up at them hopefully.

Will points to the other Mabel. "What about her?"

"Your welcome to try, but I don't think she'll tell us anything even if she knows." Dipper says.

I nod and stand up, ripping the duct tape off of her mouth. 

"Oww!" She yells, giving me an angry look.

"What do you know?" I question, getting only a glare in return.

"What do you know?" I repeat, returning the glare.

She sighs, obviously annoyed. 

"What do you know?" I demand a third time. She looks as if her mind  has drifted off into another place, and I continue to repeat the question over and over.

------Mabel Gleeful's POV------

As my pathetic double asks me the same stupid question for the 4th time, I get bored of listening and eventually just look off to the side, trying to remember when I got a hold of Dipper's journal. I've tried to remember what happened after that, and why I knew Bill that day even though I swear I had never met him before. 

I slowly close my eyes and focus on that day, retracing my steps.

~~~Flashback~~~

(Don't worry, it's not a repeat, it's something new)

The journal in my hand suddenly starts to glow, a bright golden color, and in a swirl of grey, I'm suddenly in a blank void, the room around me completely gone. 

I look around the blank grey void, confused. "What?" I question quietly. A laugh suddenly echos around the large area, followed by a golden glow appearing in the corner of my eye. I turn to see a yellow triangle with a creepy cat-like eye in the center, strangely wearing a tall black top hat , with a black bow tie just below his eye. The strange creature look a lot like that sniveling blue triangle me and my brother had summoned a while back, but way scarier, this one actually seeming like the demon we were expecting.

"Who are you?" I glare at the triangle, trying to ignore his laughter.

"The names Bill Cipher." He- I guess.. states, examining his non-existent nails. 

"Bill Cipher huh-?"

"Please, just call me Bill." He insists.

I raise an eyebrow, then shrug it off. "Alright then, Bill.. Why exactly am I here?" 

"Well, I need someone to help me with getting PineTree's journal." The triangle states, if he had a mouth I swear he would be smirking.

"Pine Tree?" I question, tilting my head, confused.

He sighs, annoyed. "Dipper." 

"You stay away from my brother!" I instantly yell, pointing an accusing finger at the demon.

"Not your brother, the other Shooting Star's brother." He says.

"Shooting what?" 

"Ohh nevermind. Look kid, we can do this the easy way, or the hard way." He states, getting a slight red tint.

"Alright then.." I say, uneasy. "What exactly do you need help with?" 

"Getting a journal." He states.

"Why do you need my help to do that? You seem like a pretty powerful demon- or whatever you are.. Can't you do it yourself?" 

"I don't exactly have a lot of power in the real world." 

"Real world? But this is the real..." I trail off at the end, looking around again at the empty grey void.

"Welcome to the mindscape kid." Bill says, turning yellow again.

I want to slap the smug look off of his face, but decide not too. "Don't call me kid, I'm not a child." I growl slightly.

"Sure you are!" He laughs mockingly.

I roll my yes, ignoring him. "So you need my help, what exactly do I get in return?" 

"You don't get to die." 

"You said you didn't have any power in the real world." I point out, and smirk at the annoyed look on his face.

"Fine, then you won't get horrifying nightmares for the rest of eternity." 

I shrug the threat off. "What harm could a little nightmare do?" 

I swear if he had a mouth, he would be grinning right now. "A weird thing about humans, they actually need sleep." 

I get another uneasy feeling. "Fine then, I'll help you, I mean it can't be that bad.." 

"Great!" He cheers happily, stretching out his tiny black hand, which was surrounded by a bright blue fire. "So it's a deal?"

I look at his hand uneasily, then hesitantly stretch my had out, shaking his. "Deal."

He releases my hand. "Ohh yeah, and one more thing, I'm not going to risk you telling anyone about this little deal, so you can't remember this, alright?" He questions.

"What?" I question. "How's that supposed to work? I can't just forget." I protest.

"Sure you can!" He cheers happily. "It's called mind erasing!" 

"What?!" I shriek, but don't have enough time to protest, as he waves goodbye, snapping his fingers.

~~End of flashback~~

I gasp, coming back to reality, but for some reason, the room is dark. I look over my left shoulder to see he window, a million stars glittering outside. It's night already?

I sigh, looking to my left to see the old man, snoozing on a chair. I guess he was supposed to watch me. My mind flashes back to the deal with Bill. "Ohh no... What did I do?" I question, looking down at my lap.
