how would take back the falls work in reverse falls
This is kinda hard to answer, so sorry if it’s not good and sorry it took so long to answer.
So, how this episode would work is honestly based on what your headcanons for the AU is, so I’m going to base this off of my headcanons (this is Mod Reverse). Other mods, please feel free to answer this as well.
So, I always believed that Bill would wait a little longer to start weirdmageddon so the twins and Pacifica would be about fifteen/sixteen and Gideon would be eleven/twelve.
After getting Dipper out of the bubble, Mabel, Dipper, Pacifica, and Gideon all head back to the twins’ mansion where Stan and all the survivors are waiting for them. Instead of the Mystery Shack being surrounded by the unicorn hair, it’s the mansion (which took forever to be honest). Pacifica and Gideon give their speech about saving the town, along with Dipper and Mabel stating how their gonna severely punish Bill. So they all agree to work together to take down Bill. They turn half the mansion into a robot using the same things as the show (with only a few things from the Mystery Shack). Stan, is of course, reluctant to help.
After getting rid of Bill’s friends, Bill comes out and instead of outright attacking them, he tries to get them to stop fighting him and give up and let him do what he wants (he mostly tries to talk to Dipper and Mabel but they don’t listen to him). After distracting him the same way in the show, Mabel would use her secondary power, teleportation, to get them inside Bill’s castle. They’d free the citizens who are stacked in the chair and get Ford to tell them the way to get rid of Bill.
From there, the events of the canon world happen here. Instead of Bill outright trying to get rid of them, he continuously begs them to give up and leave him be. They continue to refuse, and after a while, he gets tired of them and then starts to act like canon Bill. Instead of fighting them himself, he controls Wendy, Robbie, Pacifica, Gideon, Soos, and Fiddleford and makes them fight Dipper and Mabel. So while they’re running, he begins to torture the Stan twins to try and make Ford tell him how to make the oddpocalypse global.
Dipper and Mabel escape their friends and meet back up with the Stan twins and they begin to taunt Bill and insult him, and he gets angry and chase the twins around the castle. After this, all the same events happen that lead up to Stan getting his memory erased.
I can’t say for sure if the Stan twins make up or not because I’m thinking of this as I go, but they’ve at least made peace by now. The mansion and the Mystery Shack all get rebuilt and Dipper and Mabel have their birthday party as well as a thank you party for those two and Pacifica and Gideon. Those four are now friends and Dipper and Mabel have given up their sadistic ways, only using their magic for their shows now. Ford sometimes joins them in their shows as well, happy to be using magic again, and Stan still manages them all.
Sorry it’s kinda out there and not in great detail, but I just came up with this on the dot. Maybe I’ll make another, better, post about it later when I’ve got everything figured out.
