Chapter 6

*Dipper's POV*

There was a knock at the front door. Mabel ran out to get it, stumbling a few times before managing to get over to the door and attempting to turn the knob with her hands that were now covered by her sweater sleeves. She got it open and grew more excited when she saw our two great-uncles outside.

"Grunkle Stan, Grunkle Ford!" she exclaimed, hugging the two older men.

"We only saw you yesterday," Stan complained, but I could tell he was happy that Mabel was so happy to see him.

"So where's this lab?" Grunkle Ford asked, straightening his trench coat from Mabel's hug and looking around the inside of the house.

"In the basement," I told him. "Come on." I lead Mabel and our two uncles down to the basement. Mabel helped me pull the bookshelf from the wall.

"Interesting setup," Ford remarked, examining the hole in the wall and stroking his chin.

"How am I supposed to fit through that hole?" Grunkle Stan asked. "It's too narrow."

"If I can do it, you can do it, Stanley," Ford told him. Mabel went through first, I followed her, with our two great-uncles close behind. Grunkle Ford took a look around the practically empty hidden room on the other side, carefully studying everything, making sure there was nothing I had missed.

"Did you test these papers with the blacklight?" he asked.

"Yeah," I replied. "It was the first thing that came to mind. They're blank."

"To the lab!" Mabel announced, throwing her shoulder into the heavy hidden door on the other side of the room. It came open with a loud creak. I pulled the chain, turning on the dim light in the room.

"Wow, interesting," Ford said, looking around. He studied the photos of himself and of Stan and all the theories that his brother had. "It definitely looks like he thought Stan had killed me. Had he presented all this evidence to the police, Stanley could've been put it prison for murder."

"Eh, it wouldn't be anything new," Stan said. I held back a small laugh.

"Uh, there's something else we need to tell you," I said.

"What's that?" Ford asked.

"We only found this out yesterday, but, our parents put our grandfather in a mental institution ten years ago, because they thought he was insane for thinking all this. We're checking him out of the hospital today," I told them.

"Shermie's in a mental hospital?" Stan asked. "I thought I was the messed up one!"

"Not the time, Stanley," Ford said. "So, he was put in there ten years ago?"

"Yeah," I said.

"I'm not sure it's a good idea that we just check him out. He's been in the confines of the hospital for ten years he might not be ready to live in the outside world again," Ford explained.

"He's got a point, bro-bro," Mabel said. "What if he actually went Cuckoo-Bananas while he was in there? What if it's not safe to let him out?"

"Yeah," I said, thinking for a minute. "Well, how about we visit him first to see how he's doing, explain to him what actually happened and if he seems okay, we can check him out."

"That sounds good to me," Stan agreed.

"I guess that plan may work," Ford said. "Let's go see what your parents think."

*Stan's POV*

We pulled up in front of the hospital. Everyone got out of the car. I haven't seen Shermie since I was kicked out of the house after I accidentally wrecked Ford's science fair project.

"This is it," Ford said. "I wonder how Shermie's doing?"

"Well, we're about to find out," Dipper said. We went inside the hospital and walked up to the front desk.

"We're here to see Sherman Pines," Ford said.

"Just a second," the secretary said, typing a few things into her computer. "He was checked in ten years ago, correct?"

"Yes," Ford replied.

"Room 618," she replied, directing us to the stairs.

"No elevator? What gives?" I asked.

"Come on, Grunkle Stan!" Mabel exclaimed, grabbing my hand. "You're getting to see your brother!"

"Yeah, my brother that thinks I'm a murderer," I said, reluctantly following everyone upstairs. We got to room 618. Ford knocked on the door.

"Yes?" I heard a slightly depressed sounding voice similar to Ford's reply.

"Can we come in?" Ford asked.

"Sure, who is it?" he asked, in reply. Ford opened the door, stepping inside.

"It's your family," Ford told him.

"Grandpa?" Mabel asked, excitedly.

"Mabel? You've grown so much! Look at you!" My brother laughed. Mabel ran over and gave him a hug. I don't think it was necessary since she hadn't seen him since she was two or three.

"Ford..." Shermie said, after letting go of Mabel's sudden hug. "I thought you were dead."

*Mabel's POV*

"Ford... I thought you were dead," Grandpa said.

"You really think I would murder my own twin brother, Shermie?" Grunkle Stan asked him.

"I don't know any more," Grandpa replied, unsure of what to think.

"Well, he didn't kill me," Grunkle Ford told him. "I built a portal to an alternate dimension and got sucked into it. Stan here just covered for me until he got me back. He spent 30 years trying to rescue me from the other dimension, and now I guess I should have been more grateful that he did." He managed a weak smile, before hugging his twin brother.

"Alright, you...big dork," Stan said, patting his brother on the back but still a little uncomfortable.

"So wait, you were sucked into a portal to an alternate dimension, and that's why Stan was pretending to be you?" Grandpa asked.

"Yes, Shermie, that is correct," Ford told him.

"Wait, how do you expect me to believe all this? It sounds like something from a science fiction novel," Grandpa said.

"You should believe it!" I spoke up. "You built a teleporter! If that can be real, so can an alternate dimension! It is real! We fought a dream demon named Bill that was from that dimension, right, Dipper?!"

"Dipper...?" Grandpa questioned.

"Yeah, that's what we call my bro-bro now, because of this silly birthmark," I said, holding up my brother's bangs to show our grandfather.

"Mabel, stop it!" Dipper complained, swatting my hand away. "and yes, we destroyed Bill, who was from the alternate dimension Grunkle Ford went to."

"Well, then," Grandpa said. "I guess I was wrong to think that, Stan, you would do such a thing."

"And, we're sorry that we put you in here for thinking that," Dad said, stepping forward after he and Mom had been lingering in the background for the longest time.

"It's okay, son," Grandpa said. "You were doing it because you thought it was right."

"and that's why we're busting you out of here!" I exclaimed.

"Actually, we're just, legally, checking you out of the hospital," Ford said, clarifying for his brother.

"Thank you, all of you," Grandpa said. "I really appreciate you all explaining the truth to me after being in the dark for so many years.

"The mysteries of Gravity Falls can be confusing," Dipper spoke up. "But, with some work, you can understand them, and when you do, their quite interesting."

"Yes," Ford agreed. "Gravity Falls is a mysterious place, but it does explain a lot of anomalies."

"Are we just gonna stand around here talking about nerdy stuff, or are we gonna get out of here?" Stan asked.

"Sure, let's go," Ford replied.
