DISCLAIMER: I DON'T OWN GRAVITY FALLS NOR AMERICAN DRAGON.

It started as such a nice evening. The Northwests invited the Pines for a friendly family dinner and for the most part everything was going smoothly. (NOT!) It became obvious from the start that this was a mind game set up by Preston Northwest as a means to manipulate and torment his daughter Pacifica and her current boyfriend Dipper. However things took an unexpected turn when the Dimensional Dream Demon Bill Cipher reveals that he's inside Stan's head!

After the short fight over the memory eraser gun, the Pines and Northwests families along with McGucket are now sitting back on the dining table. Only this time Stan is sitting at the head of the table. For several minutes no one said or did anything. Everyone just sat quietly glaring at Stan who simply smiled with his eye still glowing. Now that they've actually had time to study his eye, Dipper and Ford could make out a faint triangular outline glowing inside Stan's eyeball. Though it seemed rather disjointed. Almost like it wasn't a complete triangle. A few minutes later the butler came in carting in a small tray over to Stan's seat. "Here's you're order," the butler said with a hint of disdain pulling off the lid on the tray. Revealing a small bowl of piping hot nachos.

Stan/Bill greedily grabbed a handful of nachos and shoved them into his mouth. "Ooh yummy. No doubt about it, nachos is definitely the one thing you humans got right." Stan/Bill chewing with his mouth open allowing several crumbs to drop out of his mouth. Disgusting everyone present. "Oh how rude of me. Want some?" Bill offering a handful of nachos to the others. No one said anything and just glared angrily at Stan/Bill. "More for me," Bill/Stan licking his lips as crammed another handful of nachos into his mouth. Bill then picked up a single nacho. One that was a perfect equilateral triangle and held it up. "You know what I love about eating nachos?" Bill asked waving the triangular snack in front of everyone's faces. No one even bothered to try responding. "Come on guess," Bill coxed. Still no takers. Bill playfully bit the nacho in half. "Because it makes me feel like a cannibal! And boy do I taste good!" Bill laughed. Spitting pieces of nachos in everyone's faces.

At this point Ford lost his temper and slammed his hand on the table! "Alright Bill enough games! What are you doing here?" Ford demanded.

"And how did you get inside Grunkle Stan?" Mabel added.

"And how are you even alive? We destroyed you!" Dipper pointed out.

Stan/Bill's expression became very dark as all the mad humor drained from his face. "Yes you did," Bill confirmed. "And you would have gotten away with it if it hadn't been for your meddling swine." Bill joked.

"You leave Waddles out of this!" Mabel screamed.

"But it's true," Bill chuckled. "You see when you used that memory gun on Stan, I was destroyed. However when that swi...I mean Waddles restored his memory guess who was restored with it." Pausing for effect. "This guy!" Bill pointing his thumbs at himself.

"You mean you've back this whole time?" Ford flabbergasted by this revelation since he had no clue about that.

"Yes and no," Bill sighed. "Yes I was back, but the incidence scarred me. Just like how the memory gun fragmented Stan's brain, it also broke me apart. All of my pieces were scattered across Stan's memories leaving me a shadow of my former self." Bill cried.

"Aw you poor thing," Mabel said. She can't help sympathizing with anyone who's crying. Even if that someone is a demented psychotic nacho possessing her uncle.

"Yes I am," Bill agreed blowing his or rather Stan's nose on his sleeve. "So for this past year I've been going around in Stan's memories collecting all my fragments. And that is no easy feat, this guy's got a lot of memories to go through. Seriously do you have any idea of how many prisons in how many countries this guy has been in? He can write a travel log." Bill complained.

"So I take it that you've got yourself back together which is why you're talking to us now," Ford figured.

"Not even close," Stan/Bill shaking his head. "I still need to find a few more fragments, and I was planing on playing possum till I was done. But then this guy!" Bill pointing accusingly at Preston. "Pulls out another memory gun forcing me to reveal myself! Speaking of which." Stan/Bill held up the memory gun and magically set it on fire. "Can't have this laying around where you can possibly use it on me." Bill mused at seeing the horrified looks on everyone's faces as they watched their one hope melting away.

"Even without that we'll still find a way to stop you!" Dipper declared.

"You're welcome to try," Bill dared.

"Bill! Get out of my Grunkle!" Mabel demanded.

"Sorry toots, but I still need to find all my pieces inside his brain. So until then me and Stan are roommates. But I promise you, once I'm whole and all powerful again, the real fun will begin." Bill laughed as Stan's eye stopped glowing.

"What?" Stan asked seeing as how everyone is staring at him. Feeling a bit confused since he has no recollection of Bill possessing his body. "Did I leave my fly open again?" Stan looking down on his pants. After a brief explanation, they caught Stan up. He took it as well as one can expect. "I HAVE THAT ONE EYED NUT JOB IN MY BRAIN!" Stan screamed.

"Sorry Stan," Ford apologized.

"Don't be sorry, do something! Get him out me!" Stan demanded slapping the side of his head as if he can knock Bill out of his ear.

"That's what I've been saying!" Mabel screamed.

"Why are you yelling?" Pacifica yelled.

"I don't know!" Mabel yelled back.

"Well stop it! It's really annoying!" Pacifica yelled.

"I know, I know." Mabel calming down a bit. "But it makes me feel better!" Mabel yelling again.

"I know!" Pacifica agreed. Soon everyone started screaming in panic as McGucket started dancing his jig.

"Alright enough screaming!" Preston barked slamming his fist on the table, effectively silencing everyone. "Now is there anyone who's not a complete idiot have an idea of what to do? Any idea that can help?" Everyone naturally turned to Dipper and Ford.

"I'm sorry but Bill destroyed all of my dimensional weapons during Weirdmageddon. I never thought I'd need to rebuild them." Ford confessed.

"Dipper surely you have some brilliant idea," Mabel begged. "You always do."

"No I don't," Dipper sadly admitted before he perks up. "But I do know a girl."

"ARE YOU KIDDING ME!" Haley screamed in anger. It's bad enough that Dipper came knocking on her door in the middle of the night interrupting her beauty sleep, bringing not only his family but the Northwests as well, and now he just drops this bombshell on her. But worst of all, she can feel her brother Jake and Grandpa Lao Shi's eyes burning at the back of her neck, judging how she handles this situation.

"It's true, Bill Cipher is inside my uncle's head." Dipper reiterated.

"Who exactly is Bill Cipher anyway?" Haley asked.

"Bill Cipher, a level 12 dimensional entity. It's been said that for eons he's been to manipulating the dreams of humans in order to open a gateway into our world." Sun explained. "Though from what I've heard, humans usually wise up to the demon's true nature and prevent him from coming."

"Guess he found a few people dumb enough to invite him in," Haley said bluntly.

"Yeah dummies," Dipper said nervously while the other members of the Pines family looked away avoiding eye contact. "So do you have a way to help my uncle?" Dipper begged.

"Hmm, the way I see it you have three options. One, we rebuild that memory gun and erase your uncle's memory again. Only this time we leave him as a vegetable." Haley suggested.

"ABSOLUTELY NOT!" Mabel recalling Stan's state when they erased his mind the first time around. She never wants to see him like that ever again, even if it means the end of the world.

"Fine," Haley rolling her eyes. "Two, we perform an exorcism and get Bill out of Stan's head."

"Let's go with that," Stan proposed.

"But if we do that, then wouldn't Bill just be loose on out world." Dipper asked.

"Yup," Haley nodded. "But the good news is that the Veil will keep him contained here in Gravity Falls."

"What exactly is this Veil you speak of?" Ford wondered.

Haley gulped realized that she just revealed a important secret. Thinking quickly she tried to come up with a logical explanation without telling the whole truth. "It's a magical barrier that keeps extremely powerful beings from the Earth. Gravity Falls just happens to be at a weak spot which is why Bill was able to enter the first time." Haley said.

"Hum, that does explain why he and his friends were unable to leave Gravity Fall's boundaries." Ford had theorized as much but he didn't think it was meant to protect the whole world.

"But wouldn't that mean that Gravity Falls"

"Gravity Falls will be his," Haley confirmed.

"What about our friends?" Mabel worried.

"Hey there's nothing that says they have to live here. We can relocate the population and seal this area off turning it into Bill's personal prison." Haley suggested.

"But...but our memories," Mabel cried at the thought of the Mystery Shack and Gravity Falls no longer existing.

"Look I'm just tossing ideas out here," Haley huffed with annoyance.

"You said there's a third option," Dipper asked.

"Yes." Haley traced her thumb across her throat implying that they should just kill Stan. Ending Bill's threat once and for all.

"THAT IS GOING TOO FAR!" Dipper yelled.

"Hey you wanted options I'm giving you options," Haley shrugged. "It's not my fault none of them is to your liking."

"There are lines we don't cross!" Dipper lectured. Even Haley's family was appalled that she would even suggest that course of action.

"Fine, I'm sorry," Haley said halfheartedly. Naturally everyone had a hard time accepting her apology, if you can even call it that, and just continued to stare angrily at her. "Look personally I really don't want to gamble on the world's future but he's your uncle so you tell me what you want to do and I'll support you as best I can. All I ask is that you think about it for a bit and try really hard not to act too recklessly." Haley pleaded.

"I guess that's all we can ask for," Dipper sighed. He was hoping that the Dragons might have a solution but obviously Bill might be more than they can handle. Still having dragons in their corner might not be a bad thing. After saying their goodbyes, the Pines and the Northwests left the Long residence to head back to their homes.

"You know they're going to try and exorcise him," Jake said to Haley.

"I know," Haley said. Of all the options, that really is the only logical choice. "I just hope I bought us enough time to come up with a solution of how to deal with Bill after we remove him from Stan's head." The entire Long Family and friends we all in agreement, but it was late so Lao Shi suggested that they all get some sleep and start fresh in the morning.

Later at the Mystery Shack.

"How could she? How could she even suggest that we..." Mabel couldn't even finish that sentence. "Do that to Grunkle Stan."

"Don't be too hard on her Mabel. After all she was just telling us our options." Dipper justified.

"I can't believe you! You're actually defending her!" Mabel snapped.

"Mabel...I"

"OMG! You fine with her hurting Grunkle Stan! You've never cared what happens to our family so that can be the big hero!" Mabel accused. Only to realize that she may have taken this a little too far.

"Okay deary I think that's enough," Stan said in his warm supportive self but clearly disapproving of what she just said.

"Dipper I'm..." Mabel tried to apologized, but seeing the horror in his eyes, she really didn't know what to say.

"You know what, we're all tired. How about we all get some sleep and decide what we're going to do tomorrow." Ford suggested.

"Yeah good idea," Stan agreed. Soon they all retired to their rooms. With the exception of Ford who decided to bunk with his brother Stan in order give him support and to keep an eye on him.

Inside Mabel and Dipper's room, the Mystery Twins were having a hard time falling asleep. Mabel still haunted by what she said to her brother, fearing that she may have just ruined their relationship forever. Dipper however was not concerned about that. Instead his mind is focused on Bill's possible return. He kept thinking about different scenarios of how to prevent that but sadly they all end with either Stan dying, becoming a vegetable, or Bill taking over Gravity Falls.

"Mabel are you up?" Dipper whispered to his sister. Even though he's mostly positive that his sister won't have the solution, talking to her does help him relax; and who knows, perhaps Mabel could stumble on the answer. It has happen before after all. Unfortunately Mabel still guilty, said nothing and pretended to be sleeping. Not wanting to wake her up, Dipper got up and tiptoed out of the room. Curious Mabel got up and followed her brother.

Mabel watched as Dipper made his way to the kitchen and make himself a sandwich. He then paced around the exhibits looking at all the made up monsters Stan and Soos made, as if they were all real. Dipper then went to the gift shop where he stopped at one of the clothing racks. Even though Mabel could barely see in the dim light, she knew with absolute certainty that her brother is crying. Most likely due to what she said, she figured. Mustering all her courage, she stepped forth to make amends. "Dipper are you alright?" Mabel asked.

"Oh Mabel I didn't see you there," Dipper sniffed wiping away his tears. An awkward silence followed.

"Look Mabel/Dipper" the twins said at the same time. The two looked at each other awkwardly before Dipper gestured for his sister to go first.

"Look Dipper I'm sorry about what I said earlier," Mabel apologized.

"Oh that's alright," Dipper assured her. "About what exactly?" He asked since he wasn't really sure about what she's talking about.

"You know about me saying that you don't care about what happens to Grunkle Stan." Mabel reminded him.

"Oh that," Dipper recalled. "Mabel you were angry, we all were, and we all said things we didn't mean. To be honest I really wasn't listening to you."

"Thanks," Mabel smiled uncomfortably. Not sure if she should be relieved or insulted by that. "Wait if that's not why you were crying about..."

"I wasn't crying!" Dipper denied.

"Dipper," Mabel teasing him.

Dipper signed in defeat. "I was just thinking that if I hadn't lost the Dimension Vest I could have easily taken out Bill as Dr. DimensionVest." Dipper looked over at the clothing rack which is full of vests that they sell to the tourist. Some of which they give to Dipper to replace the vests he ruins on his adventures. At discounted price for family of course.

"Yeah that Dimension Vest was pretty cool," Mabel chuckled nervously. Even though Dipper would never say it out loud Mabel strongly suspects that he still blames her for him having to give it up. "I know what you mean. I still keep thinking that if I had kept the magic braces instead of giving in to my sweet tooth, then I..." Mabel desperately fighting to hold back her tears.

"But weren't those were spy braces," Dipper corrected her.

"Yeah right, like anyone can make braces like those without magic." Mabel said innocently.

"Well I can't argue with that," Dipper laughed. Between the disaster at the dinner party and the less than helpful visit to Haley's house, felt good to laugh again. Sadly it also reminded them how helpless they are in this situation. "We'll think of something," Dipper promised. Trying sound more confidently than he actually felt.

"I know," Mabel fully confident that her little brother will come through somehow.

"Let's get back to bed," Dipper suggested. Mabel nodded and followed back to their room.

As the town quietly slept, Bill is busy scurrying around in Stan's memories. Now he's in Greenland, when Stan was helping Ford fish for some giant shark monster in the middle of winter. Even though Bill is crazy, he considers Ford's quest, no obsession, for knowledge and Stan's devotion to his brother complete insanity. "Why do they call this place Greenland when it's all white? At least it's not in prison this time." Bill mumbled digging in the snow. Finally after what felt like hours he found this objective. A small gold colored brick. "Finally!" Bill cheered as he picked up the brick. After identifying the piece, he quickly inserted it in an empty space in his rear. "Hey now that you have your butt back maybe you can join us in freezing our butts off!" an annoying voice joked.

"STAN!" Bill hissed.

"Yup it's me," Stan smiled. "Now that I know you're still kicking in my noggin I though I might check up on how you're doing. Looks like a good chunk of you is still AWOL." Stan commenting on all the cavities on Bill's body. Bill responded by shooting a beam from his finger right at Stan's chest. Stan simply raised his hand and blocked the incoming beam. "Oh Bill you know that you can't beat me in my own head," Stan mocked.

"Maybe not in by current state but mark my words. Once I get all my powers back, not even your feeble brain power keep me here." Bill declared.

"Please like I really want to keep you here," Stan scoffed. "But if I let you out, you'd try to hurt my family again. So I'm just going to keep you from finding all your pieces until either my brother or Dipper finds a way to deal with you. Personally my moneys on Dipper. Nothing against Ford mind you, but my nephew can really be surprising when he puts his mind to it." Stan complimented. "Until then enjoy your trip down my memory lane," Stan mocked as he walked of with his memory of Ford.

"I got to get out of here!" Bill turning red with rage. However that can't happen until he's whole again. So far he's only 2/5 complete and has over 45 years of memories to search though.
