Bill Cipher had hated the Pines family since he had first heard that they were the ones who would not only bring him to their dimension but would also be the ones to banish him from it. He had been so sure that once Mabel Pines was out of the way - honestly, she was the only reason Pine Tree was as good as he was - that he would rule and Weirdmageddon would come to pass. But he was wrong. So, so, wrong.

Now he found himself wandering through the woods a year later, nearly dead and with no other option but to seek out the family that had destroyed him in the first place.

When he had returned to his own dimension, Bill had been punished for his attempts to bring about Weirdmageddon. His eternal punishment was that he would be human for the rest of his existence.

He had power, but not much. Not enough to make any deals. At least not strong ones. And he had the lifespan of a human.

Groaning, Bill clutched at his stomach, vision swimming as he gazed down at the blood seeping between his fingers. He closed his eyes and forced himself to take a slow breath.

"I can't believe this," he grumbled, shaking his head. "I'm relying on the same people who beat me."

Sighing and knowing he wasn't quite ready to die, Bill stumbled up the steps to stand on the porch of the Mystery Shack. He stood there for longer than he should have and was just about to leave when the door opened.

"I'll be back soon, I-"

Bill's eyes went a little wider. He wouldn't say he was scared of Stanford Pines, but he was. Stanford and Stanley Pines were the two people in the world he feared the most.

The two refused to break eye contact - both being too prideful to be the first one to look away - until Bill coughed up blood, his new human body reminding him of his injuries. It was then that his thin legs gave up and he collapsed forward, slightly surprised when he felt Ford catch him.

He groaned as Ford dragged him into the Mystery Shack, shouting for someone - probably Stan - as he forced Bill over to one of the kitchen chairs.

Bill dipped forward, leaning all of his weight against Ford's hands which were on his shoulders.

"Great Uncle Ford?"

Bill went tense at the voice and forced his eyes to open to gaze over at Pine Tree and Shooting Star, both of which had just walked into the room.

"Dipper, Mabel," Ford said, pushing Bill backwards and noting how the blonde's head rolled back on his shoulders. "Could you get Stan?"

"No need...Pine Tree," Bill groaned out, peeling his eyes open and watching as Ford backed away, realization causing his eyes to go wide in horror. "Got a feeling you'll be throwing me out real soon."

"Wait, wait, wait," Mabel said, ignoring how Dipper stepped in front of her. "Bill?"

"The one and...only...Shooting Star," Bill whispered. His vision was swimming and slowly fading to black and he knew he was about to pass out. "Albeit it...a little more...human than...before. Thanks to you, Sixer...and...Pine Tree...here."

Bill didn't know what happened after that, but he no longer cared. He lost consciousness and actually enjoyed the release into his mindscape for the first time since he became a dream demon.

…..…..…..…..…..…..…..…..…..…..…..…..…..…..…..…..…..…..…..…..…..…..…..…..…..…..

Dipper stared at Bill for a long time after the humanoid dream demon lost consciousness.

"Great Uncle Ford?" Dipper said quietly. "Is that really Bill?"

"Yeah," Mabel nodded. "And why's he human?"

Ford shook his head. "I don't know, but like it or not he is human. And if we ever want answers from him, we need to stop him from bleeding out. Stanley! Come help!"

Together, Stan and Ford managed to carry Bill's unconscious human form down to the lab were they quickly strapped him onto a metal table in the large room where the portal that brought Ford back had once stood.

"So it's really Bill," Stan said quietly a few hours later after he and Ford had managed to stabilize the demon. "What made him human?"

"I don't know," Ford answered, staring at Bill through the plexiglass window. "But I intend to find out before sending him back to where he belongs."

"Think it's another one of his tricks?" Stan asked. "Why would he come here?"

"Again, another question we'll have to wait until Bill wakes up to get the answer to."

Stan nodded before huffing and turning around, waving a hand over his shoulder. "Well, wake me when he comes to. I wouldn't mind punching that dream demon's lights out again."

Ford scoffed, but he understood his brother's angry tendencies. Ford worked for hours, keeping a mindful eye on Bill as he worked on a new experiment.

Soon after one AM though, Ford lost consciousness and joined Bill in the mindscape.

Ford opened his eyes. He was in his lab, but everything was black and white and he knew what that meant.

"Y'know Sixer, if you hate me so much then why didn't you let me die?"

The voice was so unlike Bill's usual one that Ford actually hesitated before turning around to face the demon who was still in his human form.

"Bill," Ford growled. "What are you doing here?"

"Beats me," Bill answered, shrugging and clasping his hands behind his back, moving forward to stalk around Ford. "This is your mindscape after all and I don't have enough power to come here willingly. So let me ask you the same question. What am I doing here?"

Ford glared and crossed his arms over his chest. "What are you playing at, Cipher? Why did you come to the Mystery Shack?"

Ford was actually surprised when the dream demon seemed to deflate. "I was...scared," Bill admitted. "I was dying. Bleeding out. I don't know how to function as a person, if you hadn't noticed. So I went to the only person I could think of. The Pines family."

Ford was clearly still skeptical so Bill stepped away and held up his hands. "I don't have enough power to do a deal Sixer. I swear."

"I don't believe a word that comes out of your mouth," Ford growled, hands balled into fists at his side.

Bill cocked his head to the side, blonde bangs obscuring his right eye. "Fair, I suppose. I did trick you, take over your mind, possess your nephew, attempt to destroy your family and-"

"What do you want, Bill?" Ford demanded, cutting the demon off as the now human went off on some weird tangent.

"Who knows," Bill answered, shrugging. "But I wouldn't be here if there wasn't a reason. Which means you either want something from me or…"

"Or?" Ford demanded, not sure why he was even listening.

Bill shrugged. "You realize I could be in Pine Tree's dream. Or Shooting Star's? Or your brother's? My point is, there's a reason I'm in your head."

Ford woke with a gasp, sitting up and staring around him in shock. His glasses were askew and it took him a few moments to notice the demon grinning at him from the other side of the plexiglass.

Sighing and standing, Ford cast another glance over his shoulder before walking into the room to stand next to the demon.

Neither said a word and Ford could tell Bill was drunk on exhaustion. Once he ensured the straps would hold Bill down, Ford turned and left. Just as he was about to turn the lights off, Bill spoke in a quiet voice.

"My 'friends' from my dimension aren't going to be happy about my disappearance or failure to bring about Weirdmageddon. Prepare your family, Stanford. I fear the second Weirdmageddon may be approaching faster than we anticipate."

Ford didn't give Bill the satisfaction of watching him turn around, but the demon's words continued to echo through Ford's head as he made his way upstairs for dinner."

So I know it's crap, but it's my first Gravity Falls fanfiction.

I plan to have Bill and Mabel maybe become friends? I'm not sure.

If you can't tell, I really like Human!Bill.

Anyway, please review and let me know what you think!

Thanks!
