Thanks so much for the nice comments! Sorry… I know I took ages to update, but other people take longer so… yeah. Thanks again for all of you guys who like it! Also, I am not continuing my Undertale story, sorry guys I just got bored. But I am not bored of Gravity Falls! So this will probably continue!
"WHAT?" Dipper, Mabel and Ford yelled at the same time, in response to the 13 year old boy.
"He's not Bill, I AM!" Bill Cipher said with a shaky voice, taking a small step towards them.
His legs shook like jelly and he almost fell to the ground. Ford pulled the twins back, distrusting Bill now that he revealed his name. Dipper remembered what Ford wrote in journal three 'Trust No One' and was confused whether or not to trust this boy. However Mabel wasn't like those two, she liked helping people and trusted many people immediately. She still had one sweater left from when she had knitted a bunch for the people hiding out in the shack. She grabbed the yellow and black sweater and stepped towards him hesitantly. He looked up at her with fear and curiosity and Mabel handed it to him.
"Hi, I'm Mabel!" She exclaimed, before smiling widely at him.
He took the sweater and just looked at it, as if he didn't know what to do with it. Then he smiled weakly at Mabel and stuck out his hand for her to shake. Her grin widened and just as she gripped his palm his hand and Mabel's were suddenly engulfed in a blue fire. She yelped in fear and pulled away, the fire kept spreading up his arm and his eyes were full of pure fear and he started to breathe heavily and try to shake the fire away. It started to spread over his entire body and he began to scream before it stopped as suddenly as it started. But he fainted.
When he woke up he was lying in Ford's office (below the shack) with both sets of twins staring down at him or a screen behind him (AN: Stan doesn't lose his memory). Things were attached to his head and arms and his memories were being projected onto a screen.
"Oh, you're awake," stated Ford, writing down and making notes about what he saw from the memories, "We've been watching your memories and I guess we can safely say that you, are not going to betray us and kill us all." Then he narrowed his eyes slightly, "I think."
Bill blinked and shook his head, indicating that he wouldn't kill them all.
"So, my name is…" started Dipper, before Bill interrupted him.
"I know your name, all of your names," Bill explained quietly, a sad look still plastered on his face, "I watched everything, through the eyes of that-that demon."
"Bill?" Dipper asked, even though he knew what the answer to the question was.
Bills hands clenched up into fists and he muttered under his breath No! Stop calling him that! He meant to say it quietly so they wouldn't hear him, but he heard Dipper's sharp intake of breath at the forcefulness in his voice.
"Okay then," Stan spoke up (AN: random thing, I accidently wrote Satan instead of Stan at first) "We were just talking about what we were going to do with you."
Dipper and Mabel had organised with their parents (after a lot of persuasion) that Dipper was going to stay and be home schooled by Ford and become his apprentice. However, Mabel would actually stay in Gravity Falls, but go to normal school. They would go to stay with their parents during the holidays and would talk to them every day on Skype and on the phone. The two grunkles talked to Bill and each other (Dipper and Mabel just listened) and organised that (since Bill had no family to go to and probably shouldn't go to an orphanage in case he starts talking about what had happened to him and Gravity Falls) Bill would stay with them, temporarily at least. He wouldn't need to go to school (it would probably be for the best anyway) and would occasionally be home schooled with Dipper. Knowing Stan he would probably get the boy to help out at the shack for free and knowing Ford, he would want to find out EVERYTHING about Bill Cipher and about the demons and monsters that even Ford hadn't yet seen. Bill was just happy to have somewhere to stay.
"So I guess you will have to sleep on a mattress in Dipper, Mabel and Waddle's room then." Ford concluded, then he checked the time, it was already half past elevn. "Okay then kids, get up to bed. Bill I will find you some stuff to sleep with."
It took about twenty minutes for everyone to get everything ready and settle down. But soon the kids (this includes Bill since he is the same age as the twins (thirteen)) (I am saying that this happened the day before the twin's bday) roughly. He was going to say that his birthday was the day he escaped the demon because that was when he escaped and began to age again. So, going by that he was now a day older than them.
They all settled down and Dipper and Mabel fell asleep quickly, considering the week (I am saying that is roughly how long Weirdmaggedon lasted) they had just had. It took Bill a lot longer, but after about an hour he drifted off to sleep.
And then the nightmares began.
Sorry (not sorry) about that cliff hanger guys. I promise (kinda) that I will try to update ASAP. I kinda know what I am doing with this story. OH, and if you were wondering. NO BILLDIP. I don't ship it, no offence if you do, but there will not be Billdip.
