The town where I am the only one missing (Blinded AU)

Prologue

"I am Blind Ivan, and we are the Society of the Blind Eye" announced the now known Blind Ivan with the other members behind him, covering his eyes in a gesture "Formed many years ago by our founder... Our founder... Does anyone remember who he was?" Asked Blind Ivan, the other members looked at each other "we've using that Ray on our brains a lot" stated Bob Gleeful.
   "But why would you do all this? What do you have to gain?" Asked Dipper  "As you have no doubt discovered, Gravity Falls is a town plagues with supernatural strangement, no one knew how to stop it the things that bumped in the night, so our founder invented the next best thing, a way for us to make us forget, we took this upon ourselves to help the trouble townsfolk by erasing the memories of the strange things they've seen, now the people of Gravity Falls go about living their lives ignorant and happy, thanks to us." Blind Ivan finished explaining "and as a perk, we help ourselves to forget things that trouble us, everyone has something they want to forget. In fact, your own sister was about to use the Ray in herself, isn't that right?".
   "Mabel? Seriously?" Dipper looked at her sister, Mabel was looking guilty, she gave a nervous laugh "maybe..." She said "don't you see? You are ruining lives" stated Dipper turning to see them "what about old man McGucket? He lives in a hut and talks with animals, thanks to you" explained Dipper "don't you feel bad about it?" He questioned them, Ivan hesitated a little before answering "maybe be a little" he admitted before he put the Ray in his head "but not anymore" before giving a smirk "you won't be telling anyone what you found in here" he said typing "Summer" in the machine "say goodbye to your summer" he finished typing and turned to them "say goodbye to your summer" he came closer to Dipper, Mabel, Soos, and Wendy, they started to freak out.
   "Guys if we are going to forget everything, I want to confess. Mabel, during half the summer I thought your name was Maple, like the syrup, nobody corrected me."
   "I only love some of my stuffed animals and the guilt is killing me!"
   "Sometimes I say big words and I don't actually know what they mean, I mean, I'm supposed to be the smart guy, if I'm not the smart guy, who am I?"
   "Okay, actually  I'm not laid back, I'm stressed like 24/7, have you met my family?"
   Everyone started to say that they are going to miss everyone "oh, stop being a bunch of babies" Ivan said rolling his eyes, someone hit the hands  of blind Ivan, and Mcgucket arrived with a pick axe "McGucket?" McGucket cut the rope "I raided the mining display, now fight  like a hillbilly, fellers" Wendy took a banjo, Mabel a taxidermy raccoon, Soos a Dysentery informative "nobody mess" "they know too much, don't let them escape".
   Battles were everywhere, Wendy fighting with the Banjo, Mabel with the taxidermy raccoon, Dipper was running away with McGucket memories when he crash with Blind Ivan who tried to take the tube away
   "Give that tube!"
   "Never!" Ivan was about to win the tug-o-war when Dipper threw it up, passing by the tubes above and landing in a pile of memories. They raced to grab it, making each other falls when they got to close "those memories belong to McGucket" stated Dipper.
   "The society's secrets belong to us" Ivan pushed ahead, making Dipper trip. He hit the cold floor and by the time he got up, Blind Ivan was pointing the Ray to his head. Dipper looked around nervously, trying to see if someone was going to save him, if someone noticed what was going on. He saw the bald leader gave a smirk
   "This is the end of the line, Dipper Pines. By tomorrow, your entire summer will seem like a bad dream! Say goodbye to your precious memories!".
   Dipper embraced himself as he heard the Ray energize, the blue aura surrounding it. He heard the yelling stop behind him as everyone realized what was going on. Dipper could barely hear the screams and shouts of his friends as the trigger was pulled. Dipper screamed in agony. He clung to his head as he toppled over, all the information of all the supernaturals he'd seen, all the pain and development he'd been through, all his adventures with Mabel, Soos, Stan, and Wendy, streaming away into a tube. Dipper then fell to the floor, unconscious.
   "That's a first" noted Blind Ivan, he then turned to see everyone watching at him, some with tears in their eyes "Of course they are like that, they've just watched one of their best friends lose everything" Ivan thought, the other members looked at Dipper with pity "Oh come on! You are growing soft guys, this is a guy you just met!" Yelled Blind Ivan "okay, if you want to so badly" Blind Ivan slammed the tube into the television that broadcast the memories, when it started to load, the computer broke with black liquids emitting from it "too much memories, it won't load" said Blind Ivan with exasperation.
"Oh oh" the other member said "w-what do you mean by oh oh" questioned Mabel that was the first one to speak "run!" Every member of the society said, turning off the light, leaving Mabel, Soos, Wendy and McGucket alone to cry in shock. Wendy turned to see around and found a note that said:
We will try to fix this and make another television large enough to help your little friend, until them make some excuses since we are keeping him.
Atte:
The Society of the Blind Eye members.
"What will we do now?" Asked Mabel "Dipper always had a plan! Like how to fix something like this" she said trying to hold back tears and freaking out
"For now we make excuses, Mabel, we are not Dipper, we can't solve a problem like this, but we have to leave this to them, they'll know what to do" explained Soos in a try to console Mabel.
Shortly after they left the museum, leaving McGucket in his hut and heading back to the Shack.
"Umm, interesting, I think I will pay pine tree a visit".
