"Get out of our house, Gleeful Twins!"
Dipper and Mabel didn't exactly have an ordinary day yesterday, even by their standards. For one thing, they had actually slept in the middle of the forest. Their only company was each other.
Admittedly, they were both terrified. Why wouldn't they be? They were in a dark forest, and very lost. They had no clue where they were going. So, when cracks of dawn appeared on the horizon that morning, they jumped the gun, and headed straight back to the Mystery Shack.
It was still rather dark, and they failed to notice that it wasn't their Mystery Shack...
"I said get out, Gleefuls!" repeated an angry Gideon. What the heck were Mabel and Dipper Pines doing here? Actually, how? Weren't they in prison? Plus, why was Dipper wearing clothes identical to Gideon's? Was Mabel wearing a sweater? Didn't she hate sweaters? This was so confusing!
"Your house?" hissed Dipper. "This is the Mystery Shack! We live here! What are you doing here?"
No reply. What the heck? Was he just spacing out or something? This wasn't a joke! Dipper waved his hands in front of Gideon's face.
"Boop!" Mabel poked Gideon on the nose to grab his attention. Dipper did that sometimes. He would just space out, and Mabel would sometimes just poke him. No big deal.
"Why are you touching me?" He waved her hand away. "Are you just trying to use fancy wordplay to get the shack back again? It's not gonna work this time!"
"You're the one who tried stealing it! You summoned a demon, and when that didn't work, you blew a hole in the wall, Gideon!"
"You summoned the demon!" Gideon poked Dipper in the chest every few words.. "You bonded him in chains, and when you cancelled the deal, we freed him! Then you blew the hole in the wall!"
"No, you summoned the triangle guy, and when you cancelled the deal, he went crazy nuts! He became red and he took away my cuteness!" interjected Mabel. When she said cuteness, she held her hands to her cheeks.
"Wait, what?" This was confusing. Their stories seemed to match up until here. Bill was kind, and he only stole the memory because he had to. And Dipper seemed pretty passionate, and Gideon knew that Dipper had no clue how to lie. He shook his head. "Bill would never do that! He's a nice guy, a-and he wouldn't hurt anybody unless he had to!"
"No, he did it on purpose! I'll prove it!" Dipper fumbled around with his vest pocket. Where was that book?
Gideon managed to notice something about Dipper's general demeanor. He didn't seem like he was lording over, actually, if anything, he seemed just as confused as Gideon. The accent and cruel tone were gone, too. Something was definitely going on. Gideon fumbled through his vest pocket as well. Where was that book? He stopped when he realized that he would end up showing the book to one of the Gleefuls. That wouldn't be good.
Dipper skimmed through the pages and thrust the book towards Gideon. "See?"
"Wha-" The book was shoved into his hands. He read over the page before flipping over the book. It was journal three! The same one he had! But, wait. He flipped back to the Bill Cipher page. The page was very similar to the page that Gideon had, the only differences were a few words and a handful of different symbols. Dipper didn't know that Gideon had even had the book before he had tried taking it. He wouldn't have had time to make a replica. He shoved the book back into his hands.
Gideon pointed at Dipper. "I'll prove to you that Bill Cipher's a good guy! You'll see!" He ran down the stairs to grab some candles. It was only when he was midway up the flight of stairs with the candles when he realized what he was doing. He was going to show Bill to the Gleeful twins. Something told him to keep going, though. It was more of a hunch, really. And this hunch told him that this Dipper wasn't the Dipper that he knew. There was also evidence. He was acting different, too. Maybe he could trust Dipper. Who knew?
"What's up, Gideon?" He jumped up before turning around. Pacifica had snuck up behind him and tapped him on the shoulder.
"Pacifica? What are you doing here! It's only seven!"
"Your Grunkle let me in. Besides, it's fine. I couldn't get back to sleep, so I'll just hang out here for a bit."
"Fine, Pacifica." He paused. Should he tell her? "Anyways, the Gleefuls, at least they look like them, are upstairs right now. I'm showing them that Bill's a nice guy."
Pacifica placed her hands firmly on Gideon's shoulders. "Did you leave them there ALONE? Who knows what they could do alone in the house? Come on, hurry! Before they do anything!"
"But they're acting weird and different."
"Who cares? It might be an act! Hurry!"
They rushed to the room to find a sleeping Mabel and a worried Dipper. Dipper was breathing heavily and flipping pages in his book periodically. He would put the book down, curl up in a ball, only to flip through it again. Every few times he would do that, he would try to wake up Mabel. He shook her, poked her, yelled at her, but nothing was happening.
What had he done? He had shown Gideon Gleeful the book! Who knew what he would do now? He buried his face in his hands.
"Yeah," whispered Pacifica to Gideon. "They ARE acting weird and different. What's wrong with them?"
Dipper jumped up and sat upright when he heard whispers. He shoved his book back into his vest, and kept his hands in his pockets, tapping his fingers against his body nervously.
Eventually, he put a nervous hand up as if to protect Mabel. Both Pacifica and Gideon (who were in the room at the moment) could cause harm to her. He wouldn't let that happen. "Don't touch her."
"What do we do, Gideon?" Pacifica nudged him with her shoulder.
"We should summon Bill. He might know more than us about them."
"Yeah, but won't he overreact? They ARE the Gleeful twins. The ones who chained him, and you know how emotional he can get."
Gideon ignored her and flipped through the book. He layed out the book in front of him, and placed the candles around it. He lit them.
"Mabel!" Dipper tried to whisper loudly enough for Mabel to wake up, but quiet enough so that Gideon wouldn't hear her.
She grunted and turned around, mumbling something about sleeping forever.
"Gideon and Pacifica are here, and they're trying to summon Bill!"
She perked up at Gideon, and her eyes widened as she heard Pacifica's name. She sat up and glared at her.
"Pacifica," she hissed.
"Mabe-" Her word was interrupted by Gideon's chanting.
"Triangulum, entangulum. Veneforis dominus ventium. Veneforis venetisarium!"
"No! Stop it! Do you have any idea what you're doing?" Dipper ran towards him, hands in front in an attempt to push Gideon so he could stop the ritual. It was too late. The world was already in shades of black and white, and he could see the silhouette of a triangle with an eye forming.
Suddenly, Gideon was aware of a few different things. One, he and Pacifica were both in a single, large, yellow protective sphere, probably created by Bill to protect them from Dipper and Mabel. It seemed like a thing he would do. Two, Bill was flying several feet above them with red flames glowing out of his hands. Three, so was Dipper. What was going on here?
