Chapter 1, here we go. I realised that I kinda have a 40 page document full of various Gravity Falls fanfiction, some of them mine, some written versions of fan comics I've seen on Pinterest. This particular one is based on a fan comic by an artist whose name I'm not sure of. I'd love to give them credit here, so if you know them, pls let me know or tell them so they can contact me.

Anyways, Human!Bill and some sad sibling moments gonna go down here... Enjoy and review if you liked it x

...

Cradled in Bill's strong arms, Mabel stared helplessly up into his one dark mean eye. She couldn't move, totally paralysed with fear. Bill met her teary eyes and struck. Mabel's soul shifted suddenly from her body as his took over. Her veins ran black and her terrified eyes became white and empty. Her stiff arms fell to her sides, her legs went soft and dangled limply from under Bill's effortless hold.

This time she stared up at Bill, not in fear, but in obedience. She was totally under his control, like a puppet, useless without someone to pull her strings.

"No! Mabel!"

A distant cry, Dipper was running. He'd finally found his sister but it was too late. Tears forming in his eyes, he reached them.

"Wait! Please!"

Dipper saw Mabel clearly now and the realisation of defeat hit him like a sack of bricks to the chest. His sister was no longer there, in her body. He was facing Bill and a lifeless replica, cruelly modelled after Mabel.

"No! Don't take her!" he cried, stopping at Bill's feet. He craned his neck to stare into his triangular face, "Y-you can have me! Take me instead!" He begged, sinking to his knees and allowing a river of tears to flow across his cheeks. "Please! You can't take her. You have to take me…"

Deep down, Dipper knew it was too late. He'd lost his sister and there was nothing he could do to get her back, and now he was on his knees, begging for something he never would've lost if he had just listened to her in the first place.

"Please…"

Dipper's head dropped into his chest, his eyes closed and his cheeks soaked with the wave of tears washing over them.

Bill gazed down at the boy. What was that in his eyes? Pity?

And then, suddenly Dipper was shunted from existence as Bill's presence entered his body. He opened his eyes, pure white nothingness looked up at Bill expectantly. A blank face, no sign of life or emotion. Just those crude white empty holes.

Mabel dropped from Bill's grasp. Now he had Dipper. Stronger, smarter and more useful, the one he'd wanted from the beginning. She fell and as Bill freed her from his spell, landed hard on the ground right in front of her brother, who didn't acknowledge her at all. Mabel didn't move.

Dipper stood and in one swift movement, stepped over his sister's body and went away with Bill.

Mabel stirred and shifted her eyelids a little, glad to be able to move them again. Her hair fanned out across the floor, a strand tickled her chin and she scrunched up her face.

"Unnnn, Dip?" she moaned, opening her eyes slightly. A white sheet of nothing met her eyes and she suddenly remembered where she was.

"Dipper!"

The void was empty and lonely. Mabel wanted her brother, needed him. She stared around, terrified, "Dipper?!" but she was alone in the vast expanse of white. But she didn't want to believe that, not yet.

"W-where ya at, Dip?" she turned over, sitting up and gazing into nothingness, a cold empty space where her brother should've been standing. Mabel's eyes pricked and she called his name one more time before defeat swallowed her.

Dipper was gone…

I have a huuuuuge collection of these stories and I've also recently started rewatching the series with my boyfriend, so expect a few more stories to be going up shortly.

Thanks for reading, Avani x
