Waiting in the Shadows AU

In summary, Bill bides his time and waits to activate the portal, after all, what's a few decades to an immortal being? (this is kinda long so be prepared)

Everything that happened in Stan and Fords childhood is the same, Stan accidentally breaks Ford's project and he is kicked out. Ford goes to Backupsmore and meets Fiddleford and goes to Gravity Falls to study anomalies. He writes the journals and summons Bill honestly just to see if it was real. Ford still works with Bill but doesn't let him take over his body, he wants to be the one to make it, pride and stuff. After Fiddleford falls in, Ford decides the portal is (a bit) dangerous, puts it on pause, and calls Stan to help hide the journals. 

When Stan comes he and Ford talk it out and Stan talks some sense into him. Not wanting the years of work to go to waste, Ford doesn't destroy the portal, but he does shut it down and hides his journals*. Stan and Ford repair their relationship for the most part, and it takes a while, close to 30 years (wow, would you look at that). The twins come and Ford lets Dipper look through his journal. Dipper wants to go on adventures so he uses the copier to have his own journal to go on monster hunts with (and add his own things). Him and Mabel hid it from their Grunkles and went on adventures themselves. The show mostly follows canon,(Gideon doesn't have a journal though, so no dreamscapers, but he does still try to steal the shack instead by working with Mcgucket to build a giant robot (to “promote the Tent O’ Telepathy”) and the twins stop him. 

*He rewrites just the anomalies from all 3 books into one and destroys the original ones, most of his research is safe and the notes and blueprints of the portal are gone, win-win situation.. Mostly. 

Dipper and Mabel decide to tell Stan and Ford about the copy of the journal after the zombie incident (BAMF Stan, Ford is still a lil nerd since he was never in the multiverse). Stan understands (he would have done the same thing, let's be honest) and Ford is a bit upset, but he saw how well the kids handled everything and let them hang onto it. 

It's around here that Bill decides he’s waited long enough and wants to get Ford to complete the portal and turn it on. (at this point Ford doesn't think Bill is /evil/ but he is a little wary of trusting him, unlike at the beginning).  Bill goes to Ford in the mindscape and tells him that after 30 years he still isn't famous, and that he knows it's his dream. Bill is SUPER manipulative and convinces Ford to make the deal to take over his body and complete the portal. Ford doesn't tell any of this to Stan, and instead sneaks down to the basement at night to work on it. After a few days of this, Ford is sleep deprived enough that Bill takes over at night to work on the portal. 

Bill is less careful than Ford, and Stan figures out something is up, but doesn't know exactly what. He looked through the journal but all the pages about Bill were not added so he can't figure out what is happening, but he will still figure out how to stop… whatever it is.

Stan confronts Ford about it and Ford denies anything happening, he just has interesting research that's been keeping him up and Stan is worried about pushing Ford too much, especially in his sleep deprived state, so he tells Ford to just go sleep some. Bill knows he’s gotta hurry up before Stan puts a stop to him, so when Ford goes to nap Bill takes over and hurrys to start up the portal. 

Later when Stan goes to check on Ford (to make sure he's actually sleeping) he finds Bill in the basement working on starting up the portal Stan thought had been destroyed. He gets upset at “Ford” for not destroying it earlier and trying to figure out wtf is going on. Bill tells him he is Ford's muse he summoned to help him become famous because Stan was “holding him back from greatness” and all the mean things Ford was thinking when Stan was kicked out. Stan gets pissed but doesn't want to hurt his brother. Bill chooses this moment to bounce, so Stan has to deal with an unconscious brother and a demon trying to start up the portal. (at this point Stan doesn't know why the portal is dangerous, just that it is, especially if that creep is trying to start it.)

When Ford wakes up Stan tries to talk to him but just ends in a huge fight between them. Ford goes to sulk in the basement, and Bill uses their fight to get Ford to finish starting the portal. The kids know something is wrong after the fight and try to get them to hug it out. Stan is stubborn and doesn't want to talk to Ford, at least for a bit, so they decided to try and talk to Ford themselves. Stan is a responsible grunkle and goes with them, not trusting Fo Bill. They find Ford starting the portal, and a scene very similar to NWHS happens. Stan is at the button and Ford is pleading with him to keep it on. Stan doesn't want to, but he still trusts his brother. 

The portal causes weirdmageddon and everyone is too shocked to be pissed at first, but Stan is pissed that his trust resulted in this, and Ford is pissed that Bill lied to him (who'da thunk!) The younger twins have to deal with both the apocalypse and their grunkles fighting. There is no unicorn barrier around the shack, so it is no longer a safe place. Dipper and Mabel get Ford and Stan to stop fighting long enough to figure out how to stop Bill. He tells them of the zodiac so they have to work together to get everyone together. They split up into two teams, Mabel with Stan and Ford with Dipper. They go to find everyone in the zodiac, surviving in the throws of the apocalypse (similar to Dipper in canon). As soon as everyone from the zodiac are together Bill figures out he cannot leave Gravity Falls, and goes to kidnap Ford. He tries to just get the equation himself but since hsi deal was “Now till the end of time” and in weirdmageddon “time is dead” the deal is no longer in place and Bill can't get it. 

Everyone else (zodiac members and survivors) are trying to come up with a plan and Mcgucket's idea is a giant robot. Gideon suggests using the Gideon Bot since it's only moderately destroyed rather than starting from scratch. Stan is very unenthusiastic to help (his brother kinda betrayed him and he's salty and stubborn) but he doesn't get in the way or anything, he knows he still cares, even if he doesn't want to. 

The rescue mission goes well, they arrive faster than canon and see Ford being tortured for the equation. Stan feels a bit guilty at this point, the relization that if he pressed that stupid button none of this would have happened hit him and now he hates himself more (he could never hate Ford, no matter what he does). The Gideon Bot distracts Bill enough to free Ford and get the zodiac set up. Without a barrier protecting the robot it is defeated much quicker and Bill stops the zodiac before they can get Stan to join (he’s really salty at Ford, and Ford isn't exactly happy with Stan either. Ford doesn't want to blame himself so he blames Stan just a bit). 

Bill captures them like in canon and the twins distract him while the grunkles come up with a plan to stop him. Since Ford doesn't have a plate in his head they don't switch, Stan just has to effectively kill his brother after he starts the apocalypse. Logically both of them know this is the only way to save the kids- and the world- but it doesn't make it any easier. Stan still suggests they switch, “Your mind is useful, Sixer, mine's never been good for nothing”. Ford pauses for a sec and actually considers it, everything Bill said, everything that happened, but Ford still cares about his brother, and will not let him take the fall for his mistakes. No matter what happens, Ford can't hate his brother, and he still cares about him regardless. 

Ford makes the deal and Stan erases him, the pyramid falls and weirdmageddon is over. Stan feels even more guilty now, he enabled the apocalypse and then killed his brother to end it. They find Ford and he doesn't know who they are (this follows canon). Mabel and Dipper drag them back to the shack (which has been repaired since Weirdmageddon) and try to get his memories back. (“Remember when we played DD&D? Or going on monster hunts?” “Or when I showed you how to knit? The time I made your hand into a hand turkey?”) Stan is in the corner hating himself, but he doesn't want to show it to the kids. 

Ford gets his memory back and offers to sail with Stan (I love sea grunks, okay? I want them to live out their childhood dreams like the sappy old men they are) and Stan of course says yes (it's the least he can do after erasing his brother). 

On the boat Stan still feels bad about everything that happened, but he and Ford actually talk like functioning humans and Ford explains his deal with Bill better so Stan can better understand what happened. They get to live their dreams and get a happy end cause it's what they deserve!
