What? A Gravity Falls Story

Last Mabelcorn

Ford is seen sleeping on the couch while snoring loudly.

Inside of Ford's dream, he appears in a field of wheat with a ruined swingset, interdimensional portal, and the Stanowar around him.

Ford looks around as the wheat is flattened around him into the image of Bill Cipher, glowing blue.

Ford hears Bill's maniacal laughter.

Ford:"I know that laugh... Show yourself!"

He turns around as Bill himself materializes from the ground, floating in the air.

Bill:"Well, well, well, well, well, well, well, well, well, well, well!"

Multiple copies of Bill materialize as he talks, forming a ring around Ford.

Bill:"Aren't you a sight for sore eye!"

All of the Bills mirror each other's movements.

Bill:"Stanford Filbrick Pines, my old pal!"

Ford:"Bill Cipher. What do you want from me?"

Bill:"Oh, quit playing dumb, IQ! You knew I'd be back!"

Another Bill that's talking flicks Ford's nose.

Bill:"You think shutting down that portal could stop what I have planned?"

All the Bills merge into one giant Bill that floats over Ford.

Bill:"I've been making deals, chatting with old friends, preparing for the big day! You can't keep that rift safe forever."

He snaps his fingers and a copy of the interdimensional rift appears in his hand.

Bill:"You'll slip up, and when you do...!"

He throws the rift onto the ground, where it creates a massive portal in the shape of an upside-down triangle, burning the wheat field around Ford.
