+Dipper's Mindscape+

Dipper's mindscape is a vast forest with lots of trees. There one could find many things such as the paranormal beings that lived in Gravity Falls for example.

Both occupants of the mindscape right now though we're currently in a clearing surrounded by trees with a pond of water near them.

Dipper laughed when he saw Bill transforming into lots of random stuff while getting annoyed for some reason. "Bill what are you even trying to do?" He asked trying to tone down his laughing.

"Argh! Something important PineTree!" Bill exclaimed again creating another failed transformation on himself as he groaned.

"Come on Bill! Tell me please~" The teen asked in a sweet tone.

Bill rolled his eye and changed back into his normal triangular form. "Fine..." He stayed silent for a few second and then mumbled something Dipper couldn't hear.

"What did you say? Speak up." Dipper says to him.

The yellow demon sighed. "I'm trying to make a body in your Mindscape."

Dipper smiled and pulled the demon down to eye level. "I pretty much like your nacho self." He chuckled and hugged the triangle.

"..." Bill silently hugged him back.

"Do you seriously want a body Bill? Usually you'd talk bad about taking care of a human body needs before." He said, his hands playing with Bill's bow tie.

" I have my reasons PineTree and your not allowed to know." Bill told him.

The teen pouted, but gained when he came up with a great idea. "Hey Bill, can you close your eye for a for a few minutes for me?"

"I swear PineTree if this is another prank-" Bill started. Dipper interrupted his sentence and shook his head.

"Don't worry Bill it's not! Just trust me okay?"

Bill glanced at the teen and gave in. "Alright, fine."

Dipper backed away from the yellow demon and started imagining a body for Bill. Closing his eyes he started to make out the outline of the body. This was his mindscape anyways, he could do anything he wants. He thought of how tall Bill should be, then his physical features, styled hair and color, then some clothes definitely formal, and finally Bill's items. The brunet opens his eyes only to grin at his creation image of Bill's human body. "You can open your eye now Bill." Sounding very pleased.

The demon opens his one eye and wondered what the kid even did. He saw Dipper's smile causing him a thump in his heart. Wait! His heart?! Bill brought his hand over his form only to feel soft fabric over it. He made himself a full body mirror to see himself. "I have a body!" He exclaimed. Bill has short, but long blond hair, tall lean body. An eyepatch cover his right eye, wearing a yellow tail coat, white button up, black pants, gloves and dress shoes, top hat, and his signature bow tie. His eyes not vertical anymore and more human like.

Dipper chuckled and fell back into the grass when Bill suddenly talked him into a tight hug.

"PineTree! You are the absolute best! Thank you!" Bill rushed his words out while nuzzling his cheek against Dipper's.

"This is only in my mindscape Bill. It's too bad you can't one in the physical world."

Bill looked sad on the outside, but was internally smirking on the inside. 'Finally I know what PineTree wants to see me as a human.' He thought, but out loud responded, "Yeah, too bad."

Bill ended up cuddling with Dipper. Both of them sitting on the dry grass watching through the clear water of the pond as fish swam in it.

"Bill?"

"Yes PineTree."

"Are you gonna come to school with me tomorrow?"

Bill grinned and nodded. "Of course! I'm never gonna leave your side remember?" He closed his eye as he sighed. "I can't let something as simple as a car accident separate us again. I need to protect you."

Dipper smiled and faced Bill. He pecked a kiss on the human demon's cheek and blushed soon after. "Thanks Bill. Your always the best when I need comfort."

"No problem Kid." Bill replied with his own light blush on his cheeks. "Now just rest for me okay."

"You do it too." Dipper told him as he got comfortable in Bill's hold.

"Okay, I'll do it as soon as you fall asleep."

Dipper's subconscious self feel asleep at ease. Bill leaning his back against the log behind him.

"Sweet dreams PineTree."

+Mystery Shack: Next Morning+

Bill was the first to wake in Dipper's body, so he had full control of it. He practically uses Dipper's body to practice how to take care of a human body.

Bipper stretched his body and arms hearing a good crack coming from the both of them. He got out of bed and left the room to go get breakfast. Yawning as he is going down the stars he caught sight of Mabel eyes on him.

"Morning Shooting Star!" Bipper greeted energetically like he wasn't sleep deprived.

"Bill, Dipper and I starts school today so let his have control of his body." She said harshly at him.

Bipper shook his head at her. "Relax Shooting Star. PineTree is still sleeping, I'm not forcing him to let me have control." He got to the ground floor of the house and walked past Mabel to the kitchen. The fusion meet with the two older Pines in the kitchen and ate the cereal that is placed for Dipper.

The three watching Bipper were awkwardly watching him as they ate their own breakfast.

When Bipper at the last bit, he felt Dipper finally wake up. The fusion's eyes' squeezed shut like they did yesterday and opened showing those two different eyes.

"Bill, you woke up first huh." Dipper's normal voice says.

"It's your fault you don't get enough sleep. I mean you even slept before me and you woke up late!" Bill's echoey voice retorted.

Dipper sighed and placed the spoon down. "Okay fine. Can I have control of my body now? I need to get ready for school."

"Sure PineTree!"

Dipper was finally back with them, but he didn't give them a look. He got off his seat and went back upstairs to get ready for school. Leaving his family with the triangular demon in the kitchen.

Bill just stared at them with a blank expression.

"Bill." Stan said.

"Yeah Fez?" He says back.

"Stop watching us eat."

"I'm not watching you guys eat."

"Yeah you are!" Stan exclaimed.

"Nope, I'm actually watching PineTree right now." Bill remarked.

Then they heard a thump come from upstairs and some mumbled words.

Bill rolled his eye. "Seriously PineTree! Watch where you're going!" He exclaimed rushing out of the kitchen to go check on Dipper.

The Stans looked at each other with questionable looks and back at the door.

Mabel held her hands together on he lap looking down with a sad expression. 'Dipper, you can't trust him.' She thought.

+Gravity High+

The car right to the school had been long and silent. Well not too silent, Dipper and Bill had been talking together for the whole car ride before the demon hid himself again as a necklace around his neck.

Stan driving and Mabel in shotgun couldn't say anything cause of the two's constant talking. So to say they were lost I the conversation between the two, not being able to butt in either.

Stan dropped them off in the front of the school and left them there with a goodbye. "Ford will be picking you guys up after school lets you out. See you at home kids!" He drove off with Mabel waving him off.

"See you later Grunkle Stan!" She yelled and then turned to get her twin, but he was already passing through the school doors. "Dipper..."

"Mabel!" Three voices exclaimed and surprised her in a group hug.

Mabel looked at the girls hugging her and smiled happily. "Girls!" She hugged them back. "Omg Pacifica! Candy! Grenda! How are you guys?!"

"We're doing great Mabel, but why are you here? You aren't suppose to be here until summer." Pacifica says confused.

"Yeah girl, like what's up with the surprise show up?" Grenda asked.

Mabel returned to her sad expression again. "It has to do with Dipper."

"Is something wrong with him?" Candy asked.

The brunette shook her head. "No, it's just Dipper... He's been hiding Bill with him ever since Weirdmageddon ended."

"Wait, hold up Mabel. You mean that evil triangle that was leading the group of monsters?" Pacifica questioned.

Mabel nodded.

"Your explaining this to us later during school. For now let's get to class." The blond says in a serious tone.

"Alright."

+Gravity High: Lunch+

Mabel luckily had the same lunch period with her friends. She explained to them about had happened for the past few months and what happened when they came back to Gravity Falls.

"Must be tough for you Mabel." Grenda says patting her friend on the back.

The girl sighed. "I just wished that Bill never met Dipper. I'm so scared what might happen with Bill being near my little brother. I don't want him to get hurt." She says from the heart.

"It's okay Mabel. When your brother needs you and us, we'll be there to help him." Candy told her with a smile.

"Thanks Candy, Grenda. You too Pacifica, I couldn't ask for better friends." Mabel says to them happily.

The four of them stopped when they heard Dipper's voice near by. Mabel looked around and saw her twin at the register buying some food.

"Thank you." Dipper picked up the cup of soup he bought and carried it out of the cafeteria.

"Quick let's follow him." Pacifica told them.

They grabbed their bags, dumped their half eaten meal and followed after Dipper.

The said teen ate outside near the forest where he could hide for the time being. Unaware he had people following him and hiding close by.

"Bill you can come out now." Dipper says taking off his hat and opening the soup cup.

"Finally!" Bill exclaimed off from Dipper's neck. "Your teachers are really boring you know that?"

Dipper chuckled and nodded. "Yeah I know, I was the one sitting through it and having to listen to it. But I can make an exception to Mr. Linton, he's a pretty cool guy." He took his spoon and started eating his soup while being carful not to burn himself.

"Hey PineTree?"

"Hm?" Dipper glanced at him.

"Wanna see something cool?"

Dipper put down his soup and shrugged his shoulders. "Sure."

Bill grinned happily and glowed brightly causing Dipper and the followers to cover their eyes until the light dined down.

Dipper blinked a couple of times and looked where Bill was recently floating. Now in that spot stood a familiar man dressed in dapper clothing. He rubbed his eye and looked at the man again. "B-Bill?!" He stuttered.

The blond man know as Bill grinned. "You got it PineTree! Did you forget that I'm a shape shifter too?~ Kinda fooled you in the mindscape last night to see what you wanted me to look like." He walked over to the teen and picked him up in a hugging way. "PineTree why do you have to be so cute~" Bill squeezed Dipper into a hug nuzzling his face into the boy's brown locks.

Dipper laughed and tried to get out of Bill's hold. "Bill let me finish eating first. Then we can play."

Bill pouted and let go of the boy reluctantly.

"Fool me once, shame on you," He ate a sound of soup and swallowed it thinking about the puppet incident. "Fool me twice, shame on me," he took another spoonful of soup and swallowed it, now thinking about last night. Dipper took another spoonful and was about to say something when Bill said something.

"Hey PineTree! There's another unknown Gravity Falls monster." Bill says with convincingly.

Dipper turned around excitedly to look and saw nothing. He turned back to look at Bill sucking on the spoon he is holding that held the last of his remaining soup which Bill apparently finished. "Fool me three times, let's face it, your a jerk and I'm stupid."

Bill back up and laughed on the ground clutching his stomach. "B-body spasms! Hahahaha!"

The brunet laughed himself at Bill's childish action and put the garbage in the soup cup. Bill, once he stopped laughing, disposed of the waste magically in a nearby garbage.

Bill's back leaned back on the tree behind him as Dipper leaned his own back on his chest. His arms wrapped around the teen's body.

Dipper yawned and checked the time. "Bill, can you wake me up in a few minutes before my next class?"

"Okay PineTree. Just get some sleep okay?"

Dipper nodded and was lulled to sleep by Bill humming.

Bill played with Dipper's brown messy curls.

"Sweet dream PineTree."
