I do not own Gravity Falls.

It was growing dark out; the sun was slowly setting over the city skyline, painting the glass panes on the towering building various hues of orange. The sounds of the a bustling town still roared on through the approaching night, cutting through the chilling air with every yell and honk.

High above the city, however, there was silence. Behind thick windows, lit only by hanging lamps on the ceiling in the dwindling sunlight, the quiet was still prominent within the walls of the private office.

At least, it did before the man whose name resided on the door of the office, not to mention the large lettering on the top of the building, slammed the metal door open, the contact with the wall ringing through the room. Closing the door with equal force, he stormed to the desk near the window, seething, removing his powder blue suit jacket as he walked.

"Damn those twins!" Gideon Gleeful growled to himself, collapsing in his desk's leather chair with a frustrated huff. "Can I not go a single day without those super-freaks deciding to stick their noses in my business?"

Breathing heavily, his bright blue eyes closed and his hands running through his heavily styled white hair, he slowly picked up a newspaper laying face down on his desk.

"Seeing an article about my newest business deal would be a good cheer-up, in the least," he mused, straightening the paper.

As his eyes met the text, however, they widened immediately.

"Are you freaking kidding me?" he hissed, throwing the newspaper away from himself. It fluttered through the air, some pages separating from the rest as it descended, before the front page story landed face up, the heroes in the large picture smiling blindly at the lamps above.

"Tele-Twins Find Cure for Deadly Sickness" the headline read, the heroes themselves standing side by side, their brown curls touching due to proximity, each supporting a grinning child. From his seat, Gideon glared over the stacks of paper on his desk at the single sheet.

"Their only power is being telepathic, and just with each other," he whispered weakly his fingers once again in his hair, strands of white falling over his forehead. "How the hell does that help them figure out the cure to a scientifically-engineered sickness? They can think in each other's mind. That doesn't tell you how to ruin literally any plan I concoct!" Gideon slammed his palms onto his desk as he finished, his eyes wild.

"Mr. Gleeful?" his head turned to the doorway swiftly as his name was spoken, his eyes softening almost instantly when he saw his secretary and old friend Pacifica Northwest standing in the doorway, a clipboard clenched tightly in his delicate hands.

"Umm, yes?" he said quickly, trying to make himself look more dignified as he pushed his stray hairs back from his forehead.

"Your five o' clock appointment is here."

Gideon blinked in confusion.

"I... don't remember scheduling one..."

Pacifica sighed.

"Gideon, it's not exactly an official business meeting."

Gideon's eyes widened in memory.

"Ack, of course. I had forgotten. Send him in, Pacifica."

"Of course sir."

As she left, Gideon quickly struggled to put back on his suit jacket, and was slicking his hair back with hair gel when the lights suddenly went out.

"Wha-" he started to exclaim, only to be interrupted when he saw a sudden glow inches from his face. "Ahhh!" he fell back into his chair.

Gideon scowled when the lights came back on, the sound of a nasally laughter ringing out.

"I assume you're the infamous 'Nightmare' I've heard so much about?" Gideon asked in an annoyed voice as he saw a hooded figure in the middle of his office.

The figure pushed down his hood, revealing his shaggy brown hair, completely covering one of his eyes, which seemed to be glowing faintly in the half-light, bright yellow uncovered eye, deep bags underneath said eye, and a sinister smirk.

"Bill Cipher, the thing of Nightmares, at your service, Mr. Gleeful!" he replied, still grinning, as he dramatically bowed, sweeping his cape behind himself.

"Was the flashy entrance really necessary?" Gideon sighed, rubbing his forehead with one hand.

"Yes."

Gideon appeared like he wished to reply to the statement, but eventually just shook his head, dropping the topic.

"Does your presence mean that you're willing to assist me?" Gideon droned, folding his hands on top of his desk.

"It depends on what you're asking."

Gideon smirked back at Bill.

"Are you familiar with the Tele-Twins?" he asked in a mock casual voice.

He felt victory within his grasp as the glow behind the tufts of hair suddenly gave a bright flash.

"When do I start?"

Gideon laughed, leaning back. Soon his plans would have nothing keeping them from being fulfilled.
