I am suddenly creeped out with the movie 'Meet Bill' (No offense)
Aww, Billy Willy, you look cute in here~
Bill: SHUT.UP.
Me: Never~ Aww, actually I have a pic of you~
Bill: NOOOO!!! REMOVE THAT!!! 
Me: Also never~
Oh, I'll just do it. I don't own the characters in my stories. Or else, they would be crying for mercy right now. Remember! Reality is an illusion. The uni-
Bill: SHEESH KID THAT'S MY LINE! 
Me:*unfazed* -verse is a hologram. Buy SILVER. BYEEEEEEEEE!!!
Bill: THAT WASN'T SUPPOSED TO BE SILVER!

(Y/N)'s P.o.V.

    I just walked away from the cliff. 'Demons runnin' round again,' I thought with a sigh. 
    "(Y/N), you're- where did you get those scratches?" Dipper asked. I chuckled nervously.
    "Well, stuff happens. I'm fine though. I'll just bandage 'em up," I replied. He kept staring at me quizzically. 
    "(Y/N)...I get the feeling you're hiding something," he said suspiciously. I grinned nervously. 'Didn't know I had Sherlock as a cousin,' I thought. I took his hat and put it in my head, leading to his protests.
    "Come on, Dad. I want some free time," I said sarcastically.
    "Oh shut up," he replied with a laugh.

    "Since it's your first night here...can we have a SLEEPOVER?!" Mabel said energetically.

    "Sure! You can go in right now, actually," I told them. Mabel looked like she was gonna explode with happiness.

    "We'll just get our stuff," she said as she grabbed Dipper's hand and they ran up to the attic.

*Time Skip brought to you by Ash di Angelo*

    "And then the gnomes started chasing us. They formed a giant-am I supposed to say that...I mean...giant and gnomes don't- forget it- gnome thing and chased us. The golf car was amazing. It saved our sorry lives back there!" Dipper finished.

    "So you nearly married a gnome," I told Mabel and she just punched my shoulder playfully. 

    "I really hoped he was a vampire, though," she said.

    We continued to chat about nonsense and stuff. It was already about 9:00 in the eve that we stopped.

    "G'night guys!" I said as I turned off the lights. They also muttered good night.

        When it seemed that they were already asleep, I pulled the journal out of my satchel and casted a faint glow. I let the little light float about it as I flicked it to a random page.

    'Gravity Falls, Oregon, is one of the weirdest places on Earth. No science has proven yet the paranormal beings in this land. Our trio have not yet uncovered all the mysteries in this town, but we're working on it.
        Among the most dangerous things in here is the dream demon, Bill Cipher. He seemed to be a gentleman at first, but then, I un-'
        I quickly shut the book. I saw Dipper sit up and I dissipated the light. I pretended to be asleep. I watched him as he pulled out a journal similar to mine but with a number 3 on it. He also pulled out a UV light from his vest, flicked it open and scanned the journal. I walked towards him silently.
        "Whatcha reading?" I whispered behind him. He nearly screamed (which would've woken up the whole town), but I covered his mouth. "Sheesh! It's just me!" I whispered a bit louder than earlier.
        "You.Freaked.Me.Out," he said in a low voice. 
        "So, I repeat my question earlier: whatcha reading?" I said disregarding his comment.
        "Uh, it's a...journal I found in the woods. Maybe you sensed it already, that this town has more to it than what meets the eye," he replied. "This journal proves that I was right; there are weird things going on in Gravity Falls."
I wondered if I should show him mine, but I thought I shouldn't. After all, it was for me. Showing it to him would mean revealing my identity.
        "Maybe you should sleep and check it out tomorrow. You seem like you need more sleep," I said. He listened and went back to sleep. As I heard his soft snores, I went out to the roof deck. The night air hit my face softly. I was in peace until...
        "Well, well, well. If it isn't princess," Bill (in human form) said. "Nice to see you again, (Y/N)!"
        "Not the same to you," I replied.
        "Aww, I can't say I'm not offended. Anyway, because of your chit chat with Pine Tree and Shooting Star, I've been given the opportunity to scan your mind!" he said rather enthusiastically.
        "Gods dammit. I knew I should have mastered the arts of occlumency (just like in Harry Potter: you learn occlumency so that others won't be able to enter or read your mind so easily) more," I muttered to myself. 
        "And now, I know you're on a quest! You're a demigod! It's weird to me though, meeting a 21st century one. The last I saw was Achilles. Didn't bother much about them," he said. I narrowed my eyes on him.
        "And you're gonna propose your deal again?" I asked through gritted teeth.
        "Why yes! So do you accept?" he thrust his hand out which now had blue flames.
        "You keep the secret...and I return the favor. Since I love getting in trouble, deal," I said as I shook his hand. The blue flame reached up to my hand but I didn't let go. He was about to draw his hand when I changed the flames to green.
        "Wha-what?" Bill was startled.
        "I don't take deals lightly, Cipher. So, we're also doing this my way. My conditions for your request is that I get some privacy-especially in the shower, you don't turn me to your puppet, you can't kill me, you cause NO harm to the Pines family and other residents of Gravity Falls-unless I see it necessary-, and you don't get to judge what I wear," I stated firmly. "Do you swear this all on the River Styx? Do you take the Unbreakable Vow even if there is no witness?"
        "Whatever that is, I swear on the River Styx that I'll abide to the stuff that you just said. And I take the Unbreakable Vow whatever that also is," he said rather quickly.
        "Oh, lemme just tell you. When you break an Unbreakable Vow, the punishment is death," I said cheerfully."This is why you should never mess with a demigod."
        "Fine. But now...for my request...I stay with you!" he piped. I gulped. 'Hades...I live with the Pines...and...'
        "You didn't think I'd request that, did y'a? I also get to follow you around and stuff like that!" I just glared at him. Even with my precautions, he found a way to trick me.
        "Ugh fine! But if you ever break the deal..." I gave him a death glare,"You're gonna regret it."
        "Sounds great to me!"

        Little did we both know, that deal just changed our lives.
