Chapter 1: We Met Again

Chapter Text

Ford hunched over his journal, the dim glow of his desk lamp casting shadows across the cluttered study. The faint smell of ink mingled with the scent of old paper and burnt coffee, lingering in the chilled evening air. Outside, the wind howled, rattling the warped glass panes of the shack’s windows.

The room was a testament to his restless mind—a chaotic symphony of scattered papers, forgotten experiments, and half-finished blueprints. Strange artifacts lined the shelves, their origins alien and their purposes unknown.

His focus locked on the anomalous reading that had jolted his senses earlier that evening. The pen in his hand scratched against the old page as he tried to make sense of his data readings. Yet, even as he wrote, a shadow lingered at the edges of his mind—an echoing voice he couldn’t shake:

“WE’LL MEET AGAIN, SIXER.”

Ford slammed the pen down, his chest tightening. He rubbed his temple, muttering under his breath.

Focus, Stanford. It’s over. He’s gone. You left him for good.”

But the situation says otherwise. The lights in the shack flickered. A strange static filled the air. Before Ford could reach for his blaster, a flash of yellow light illuminated the room.

Ford stumbled back and his words trembled.

No…This isn’t possible.”

 

Suspended above the desk, looking far smaller than Ford remembered, was Bill Cipher.

This wasn’t like the omnipotent entity Ford had fought for the last 30 years. Bill’s glowing form flickered unstably, and his single eye darted nervously around the room in fear. Cracks ran through his surface, emitting faint wisps of blue flame.

“WELL, WELL, WELL,” Bill rasped, though his voice lacked its usual strength. It was almost desperate.

“Get out,” Ford snapped, grabbing his blaster swiftly and aiming it at the entity. “I don’t know how you’re here, but I swear I’ll—”

“YEAH, YEAH, SHOOT THE TRIANGLE GUY.” Bill waved a small hand weakly, the motion more dismissive than his tone. Bill didn’t retaliate, didn’t dodge, didn’t even float away. Ford hesitated.

“Aw, come on, Sixer,” Bill said, his voice cracking as his tone down his usual high screeching. “You think I want to be here?”

“You don’t get to—” Ford started, but Bill suddenly shuddered violently. A sharp crack split through the room as a piece of his triangular form in blue chipped off, disintegrating into ash.

Ford froze. “What…?” Ford lowered his blaster, his curiosity warring with caution. “What’s happening to y—”

Knowing Bill’s nature, Ford readjust his composure and levered his blaster again. “Quit with the mind games Cipher, I don’t need you anymore.”

“Oh, you know,” Bill said weakly, his tone a pale imitation of his usual mockery.

“GETTING ERASED FROM EXISTENCE. FUN TIMES. FIGURED I’D DROP BY FOR OLD TIMES’ SAKE.”

Ford started. For all his hatred of the demon, he couldn’t ignore the undeniable: Bill was dying. And despite the chaos, destruction, and manipulation, Ford felt a pang of something he couldn’t quite name. Pity? Regret? Or perhaps the faintest bond they’d once shared, long before the betrayal.

“Why are you here?” Ford asked quietly.

Bill’s single eye flickered like a dying ember. He choked on his words. “BECAUSE YOU’RE THE ONLY ONE WHO CAN FIX ME.”

Ford had faced countless anomalies in his lifetime—things that defied the laws of physics and logic. And yet none of them compared to the creature now crumbling before him. Bill Cipher, the twisted mind-reading manipulative triangle, the destroyer of countless dimensions, and the worst mistake Ford had ever made… asking for help.

“Fix you?” Ford’s voice was laced with incredulity. “Do you hear yourself? Why would I ever lift a finger to save you?”

Bill’s glowing form sputtered dangerously as another shard broke away from his triangular body. His eye narrowed, but there was no mocking laughter or biting retort. Just a silence that felt wrong coming from him.

“BECAUSE…” Bill finally rasped, voice strained and brittle. “IF I GO DOWN, I’M TAKING YOU DOWN WITH ME.”

Ford’s stomach dropped. His grip on the blaster tightened. “What’s that supposed to mean?”

“OH, YOU KNOW HOW IT IS, SIXER.” Bill’s eye dimmed as his edges flickered erratically. “MY ESSENCE OR 'SOUL' IS KINDA GLUED TO YOUR DIMENSION. I’M THE LAST SHARD OF SOMETHING BIGGER. IF I GO OUT OF WHACK, THIS LITTLE CORNER OF THE MULTIVERSE GETS DRAGGED DOWN WITH ME. YOUR PRECIOUS GRAVITY FALLS, YOU KNOW WHAT'S NEXT."

Ford’s mind raced. He wanted to dismiss it as another one of Bill’s tricks, but the unstable energy radiating from the demon suggested otherwise. Bill wasn’t lying—at least, not entirely.

“What do you mean ‘glued’?” Ford demanded, his voice hard, but not fully untrusting. “You were defeated. Erased. You shouldn’t even exist!”

Bill chuckled, a weak, hollow sound. “YEAH, WELL, THE BIG GUY UPSTAIRS DIDN’T EXACTLY LEAVE ME WITH AN EXIT PLAN, DID HE? THANKS TO YOUR TWINSY, I’M NOTHING BUT… SCRAPS.”

“Stan?” Ford’s brow furrowed.

“OH, DON’T GET TOO SENTIMENTAL,” Bill sneered.

“YOUR BROTHER’S MEMORY WIPE DIDN’T KILL ME. IT JUST… SCATTERED ME. LEFT PIECES OF ME FLOATING AROUND, TIED TO THE ENERGY OF THIS DUMPSTER FIRE YOU CALL A DIMENSION. AND NOW, I’M FALLING APART AND TAKING YOUR WORLD WITH ME.”

Ford’s hands trembled, though he tried to hide it. The thought of helping Bill Cipher churned his stomach.

“I don’t trust you,” Ford said bluntly. “How do I know this isn’t one of your insane schemes to regain your power?”

Bill’s form flickered again, his voice losing its sharp edge.

“TRUST ME, TRUST ISN’T IN THE CARDS, SIXER. BUT IF YOU DON’T DO SOMETHING, THIS DIMENSION IS GONNA HAVE A BAD TIME. YOU WOULDN'T WANT THAT DON'T YOU?”

Ford bit his lip. Logic told him to let Bill crumble into nothingness, to rid the universe of this menace once and for all. But logic also told him that the energy Bill radiated was dangerously unstable. If Bill was telling the truth, if his destruction really would drag Gravity Falls down with him — Ford couldn’t take that chance.

Reluctantly, Ford holstered his blaster. “I’ll help you. But only because I refuse to let you destroy this world.”

“OH, SIXER,” Bill said weakly, his cracked form flickering like a dying flame. “YOU’RE AS GULLIBLE AS EVER.”

Ford’s jaw tightened, decided to ignore the jab.

“If we’re going to do this, I need to know everything. No lies, no half-truths. If I even suspect you’re trying to manipulate me, I won’t hesitate to finish what Stan started.”

Bill didn’t answer immediately. When he finally spoke, his voice was quieter than Ford had ever heard it.

 

“DEAL.”
