Human!Bill Cipher X Reader - Mine Since Always

The Universe is a Hologram,

Your Pov

After a long day, I said goodbye to the Pines twins and wandered back home, smiling while remembering all the cool things I'd found out about in the journals and wondering why I'd never seen them before.

As I walked through the front door, I was wondering if I ever would.

Through dinner, I wondered if I ever had, but they'd been disguised.

As my eyes closed at the end of the day, I wondered if I'd ever actually meet the fancy dorito that was Bill Cipher.

~In dream~

'Where am I?' I looked around. I was standing in a clearing that seemed pretty normal, except it had all these weird runes scattered about on different sized rocks and glowing crystals sticking out from the huge pine trees surrounding the clearing. 'Weird.'

I noticed my voice wasn't coming from my mouth like it should, but rather, when I went to speak, it echoed through the air and the glowing crystals would get brighter the louder my voice was. I smiled.

'Awesome.'

"Sure is kiddo."

'Ahh!' I spun around to find the extra voice in my dream. 'Who are you!?'

The man behind me looked oddly familiar. It took a second to recognize him.

'Wait. You're the fancy dorito that for some reason now does not look like a dorito.'

Bill's eyes, well, eye and inverted triangle eyepatch, widened before a huge cheshire cat grin spread across his face. Pointy teeth and all.

"I shoulda guessed you'd be smart enough to see through it. Kid, you're a one-of-a-kind meatbag. Here," He snapped his fingers and a racoon appeared. "For you kid, a coonskin hat." And with another snap of his fingers, the fur from the racoon began to peel of the animal, not seeming to mind the fact it was being skinned alive, and molded itself into a hat, which then floated onto my head, leaving the animal there with only its skin.

'Ew, no! Put it back on the animal!'

"You humans are so weird. Why is this one any different to the ones in the store? You guys kill animals all the time for stuff like this. I've seen you eat meat. You can't tell me this isn't the same thing."

'Ok, yeah. But I don't want to see it happen. Humans contradict themselves like that all the time. We eat meat, but if you were to kill an animal in front of me then tell me to eat it I wouldn't.'

"You make no sense."

'I know.'

...

'WAIT!! You're Bill Cipher! I'm supposed to stay away from you. Damn it. Didn't even last a day.'

Bill lost it laughing.

"Yup, you are definitely my favorite human so far." He put the fur back on the racoon and it ran off. "So kiddo. I know that you were told not to make a deal with me, but what'd ya say?"

'No thanks.'

"You sure? I can give you literally anything you want."

'Nope. I don't need or want anything. Not right now anyway.'

"HEY THEN!! How about this. We make a deal, but you don't have to decide what you want your half of it to be until you've decided what you want. Listen, I'm fine with how things are going in Gravity Falls right now, so I don't really want anything right now anyway! So how about we go with this; at any given time that either of us wants to use our side of the deal, we simply call the other and initiate it. It can be anything that either of us wants, as long as it's within either person's capability. No take backsies. Deal?"

He held out his hand and glowing blue flames appeared. I hesitated.

'Fine, but only under the condition that the deal can not harm any person, including us and everyone in Gravity Falls, and it doesn't include me having to give you myself of another person to possess. Deal?'

"Ughhhh, fine. Deal."

I shook hands with the dream demon, not knowing that this deal would change my life forever.
