A Dangerous Game (Bill x Reader x Dipper)

Under a Blazing Sun

It's been about half a day since you and Dipper attempted to make pancakes

You, Mabel, and Dipper were sitting together watching TV and looking into the journal every time a commercial came on.

There wasn't much you could learn about Bill other than the stuff you already knew.

Dipper looked at you concerned, and soon after so did Mabel.

"Its okay, Bill will get tired of using your body at some point." You said trying to reassure them.

"Hahah will I? It's pretty entertaining being in Dippers body!" The familiar voice and cat like eyes flashed onto Dipper like a light.

"Ahhh!" You and Mabel both scooted back.

"Surprised? You shouldn't be, remember your the one letting me do this" he winked and pointed at you

You hung your head dreadfully, it's true... you were the one who caused this

"Hey you saved Dipper, you had to do it, I would've done it too" Mabel tried to comfort you but to no avail, you put on a fake weak smile anyway and thanked her

Bill looked.. annoyed? At Mabel.

"Hey shooting star don't you have somewhere to be?"

Mabel thought for a moment then proceeded "oh yeah.. I have to work Wendy's shift since she isn't here today. I'm sorry y/n"

"It's okay.. I dealt with him by myself before" I guess I should get use to being with Bill alone.

Mabel ran off and you looked to the floor and stayed silent

You could his eyes watching you curiously but you fought yourself not to look at him

"What, you scared of me now? I did save your life" he cooed, you could see his grin from the corner of your eye "you should be greatful"

You spit out an annoyed groan and grabbed his arm, dragging him upstairs

He took this opportunity to wrap his arm around your waist, walking next to you up the steps proudly

You pushed him into the wall with all your force

"Ow.." he groaned but quickly got back up and followed behind you at a safer distance

You sat on Mabel's bed and rubbed you head, sighing heavily

Bill sat on Dippers bed and watched you

"Why did you help me?" You asked suddenly

"Hm?"

"Don't pretend it didn't happen, once you saved me you like.. hugged me and stuff" your face grew red from embarrassment but you wanted answers

Bill was quiet for a bit but then spoke

"Your no fun when your sad"

"So that's it? You just decided to be nice and Actually care for another living thing just so you could torment them again later?"

"That's not what-"

"Your an absolutely disgusting monster you know that?"

".."

"You probably smile every time you think of the people you killed"

"Hey now I-"

"You probably never loved or respected ANYONE and you don't even care"

"Watch what your saying-"

"Your pathetic! You wear your destruction like a crown! You-"

"ENOUGH" Bill, who was clearly upset, lunged at you, holding you down on the bed, his eyes weren't a soft yellow anymore. They were a blood red, with now golden yellow slits.

"YOU THINK I ENJOYED ALL OF IT? YOU THINK I JUST LOVED TO WATCH MY FAMILY BURN? MY WHOLE EXISTENCE IS A CURSE"

His screaming voice echoed in your head and boy did it scare you, it scared you to the point that tears threatened to fall, you were frozen, unable to move.

But that wasn't all. When you looked him in his eyes you saw everything, you saw him burn his own dimension to the ground, you saw his family being destroyed, you saw the... regret.

He got off you as his eyes slowly returned the usual yellow, his breathing was heavy.

You turned onto your side and just stared at the wall, while small and quiet tears ran down your face. You heard him leave, you didn't know where but at the moment you didn't care.

The images you saw from Bill kept replaying in your mind until

"Oh god.. he still is in Dippers body.."

You got up, dizzy and a bit wobbly, you wiped your tears away and left the shack, it was extremely hot this day, beads of sweat ran down your face as you ran through the woods, your first place to look was the waterfall but he wasn't there.

You thought you heard something further in the woods, and even though it was a bit off trail, you went anyway.

You slithered through the trees and rocks, going deeper and deeper.

"Hes not here..." you panted

You turned back and ran through the muddy soil as the sun beated down on you even more.

You didn't know where you going. You thought his was the way back to the waterfall, but it wasn't..

You were lost.

You stood around, turning left and right but the woods was so unfamiliar.

"No.. no no no!" You began to cry, your warm tears only made the heat worse. You felt more and more light headed until finally...

You collapsed.

Luckily, you weren't truly alone, Dipper was with you, in the mindscape... but still by your side.

Okay So this might have been a bit confusing if you aren't a die hard Gravity falls fan XD the whole thing with Bill regretting killing his family and dimension wasn't made up. I based it off of the Axolotl's poem. In it there's a line that said "watched his own dimension burn, misses home but can't return, says he's happy, he's a liar, blames the arsin for the fire" so ye... thats were it came from. Look it up if you want to read the full poem. I just thought it would add more drama.
