"Bill let's go watch Pony Heist!" Mabel said dragging Bill over to the poster.
"I am not watching anything called Pony Heist." Bill said.
They ended up watching it anyway.
"Ahh, the colors, the noises, the music!" Bill groaned.
"I know right! It was awesome!" Mabel cheered. "Now let's watch Pony Heist 2: Revenge of the Unicorns!" Mabel said.
Bill grabbed Mabel's hand and dragged her back to the Mystery Shack.
1 month later
"I'm gonna have to leave Bill." Mabel said sadly. "But I'll be back next summer."
"Mabel you can't leave! I like, just got back!" Bill said.
"I have to go." Mabel said sadly.
Bill hugged her. "I'll miss you."
"I'll miss you too." Mabel said getting into the car. "Love you."
"Love you too." Bill said.
Her car drove away. "Bye Mabel." He whispered. He sighed as he walked into the Mystery Shack. Suddenly, an idea struck him. "Mabel!" He called running in the direction of the car. He snapped his fingers so he would teleport to the side of the car.
He ended up in the front of the car.
"AHH!" Bill screamed as he put his arms in front of his face.
The car stopped just in time.
"BILL!" Mabel shrieked. "NEVER DO THAT AGAIN!" She screamed slapping his arm.
"Ow!" Bill said. "I almost get ran over and you slap my arm?" He teased.
"Why are you here?" Mabel asked.
"Oh, so do you want me to go then or..." Bill teased.
"No, no!" Mabel said. "Just tell me why you're here."
"Well I was thinking that I could come to Piedmont with you." Bill said.
Mabel hugged him. "That would be awesome!"
"Let's go!" Bill said getting in the car.
5 months later
"Why is this stuff so cold?" Bill asked.
"Well, because it's snow!" Mabel said.
"And I've seen people do these things called snowball fights. But I don't really know how to play." Bill said.
Suddenly, something cold hit his face. "Mabel what was that for?" He said.
"That's you play snowball fight! You make little balls out of the snow and then you throw them at other peo-" Mabel was cut off by a snowball hitting her face. "Exactly!" She cheered. Mabel threw another snowball at Bill.
The fight went on for what seemed like forever.
"Come inside kids, I've got hot chocolate!" Mrs. Pines said.
"Sure thing Mrs. Pines." Bill said wiping all the snow off of his jacket.
"I'll meet you guys inside." Mrs. Pines said, walking inside.
"That was awesome!" Bill cheered.
"I know right!" Mabel said.
Bill kissed her cheek. "Let's go inside."
"Ok." Mabel said.
And holding each other's hands, they walked inside.
6 months later
"It's good to be back!" Bill said taking in the surroundings. The Mystery Shack, the forest, and even the little goat.
"Look! The goat is still here!" Mabel squealed.
"Pacifica!" Dipper greeted as he hugged Pacifica.
"I missed you guys so much!" Pacifica said.
"Grunkle Stan!" Mabel greeted as she tackled the old man in a hug. "Grunkle Stanley!" She greeted as she hugged the other man.
"Hey Mabel!" Stan said. "Hey Dipper!"
"How are you?" Stanley asked.
"As awesome as ever!" Mabel replied.
"How about you Bill?" Stanley asked. Since Bill had returned almost a year ago, Stanley had been nicer to him.
"Great!" Bill replied. "Come on Mabel let's get unpacked!"
"How about we go on a mystery hunt instead?" Dipper suggested. "Just the four of us."
"Deal!" Bill said. "Mabel?"
"Sounds great!" Mabel cheered.
"Let's do it!" Pacifica said.
The four friends ran into the forest.
5 years later
Bill had been so nervous that he forgot his vows.
Luckily, he had them written down in his pocket.
Mabel was trying to hold in a laugh as the man searched his pockets for his vows. They were both 25 and Bill had proposed a couple months ago. Mabel was so happy that she tackled him to the ground in a hug.
Finally Bill started saying his vows.
Mabel started crying.
So did Mrs. Pines.
And Stan.
And about everyone in the room.
Until finally,
"You may now kiss the bride."
Present Day
"And that kids, is how your mom and I met." Bill concluded.
Mabel walked over and sat down on the couch with her husband. "It's true." She said.
"Daddy, you aren't actually a dream demon." Their five-year-old, Melody, said. "Are you?"
"Of course he is!" Their second oldest child (by 5 minutes), William, said. "Because he's awesome!"
"Thank you son!" Bill said as he ruffled the seven-year-old's shaggy blonde hair.
"Prove it." The oldest child (once again by 5 minutes), Sky, said.
Blue flames danced in the palm of the man's hand.
"Woah." Sky said. "Why are you just telling us this now?"
"Well, we thought you weren't ready back then." Mabel said to her children.
"Sky, give me your hand." Bill said.
"Um, ok Dad." Sky said moving her hand to his.
Blue flames danced in her hand.
"Am I a dream demon too?" Sky asked as she examined her hand. "Is that even possible?"
"No you're not FULLY dream demon." Bill explained. "You've just got the powers."
After a couple more tests, it was concluded that all of them had powers.
"Now you guys can't tell anyone." Mabel said.
"But why?" The twelve-year-old twins said at the same time.
"Because you can't trust anyone in Gravity Falls." Bill said. "But you can trust your siblings and your mother and I."
"Why can't we trust anyone?" Sky asked.
Sky had taken on Dipper's traits. Adventurous, intelligent, and stubborn. William got Mabel's traits. Funny, optimistic, and carefree. And little Melody was still a mystery.
"I think it's time we give them the thing." Mabel said.
"Kids, here is something you all need to take good care of." Bill said handing Sky a book. "Sky, I'm giving this to you. Your Uncle Dipper had this very book. There are three others."
"Is this number 3?" Sky asked noticing the 3 on the cover. "And why does this hand have 6 fingers?"
"You'll find out." Mabel said. "Me and your Uncle had a lot of fun with that journal. But be careful, it's really dangerous. I would know, it's how I met your father." Mabel said.
Bill lightly slapped her arm. "Did you know your Uncle write the fourth journal?"
"Our Uncle is awesome!" William cheered.
"And I have a special gift for you." Mabel whispered.
"Ooo! What is it?" William asked.
Mabel grabbed something from the table and handed it to William.
"A GRAPPLING HOOK?" William yelled. "THIS IS AWESOME!" He walked into the center of the room. "GRAPPLING HOOK!" He shot the grappling hook up into the air. It caught a beam and he was hanging in the air.
"Yup. Definitely took after me." Mabel beamed.
"Why don't you two go out on a mystery hunt?" Bill suggested.
"Gnomes, unicorns, zombies, and height altering crystals?" Sky exclaimed. "I always knew this town was crazy!"
"Woah look at that gnome!" William said. "Let's find one of those!" He said running out the door with Sky
"Be careful! They might want to take Sky as their queen!" Mabel said.
"Okay Mom!" Sky shouted back.
"I remember when that was me and Dipper." Mabel sighed. "Now I need to go inside and make a new sweater!" Mabel cheered.
They turned around and so blue fire surrounding the house.
"I'll get her." Bill groaned.
"I'll be right back." Mabel said holding a leaf blower. "I need to give this to the twins."
"I'll see ya later." Bill said.
"Bye." Mabel kissed his cheek and took off into the forest.
They went their separate ways. One into the house, and the other into the forest.
Life was crazy.
But they could handle a little crazy.
Mabel rushed through the forest thinking about one thing.
I'm so glad he was not a unicorn.
