+Bill's Castle: Gravity Falls room- Next Day+

Mabel had worn the necklace that Bill had given her, even though she didn't want to she still put it on. She looked around the room watching everyone in their bubbles either talking to the person closes to them or napping. She sighed, oh how she longed to see her twin again.

The door to the room open with cause the people that were awake to look towards the entrance. Bill came in, but not with his usual grin, more or a serious look. "WAKE UP!!!!" The blond yelled loudly causing the rest of the group to stir awake.

"What do what Bill?!" Ford exclaimed grumpily rubbing his eyes.

"I'm here on some request, so shut your trap till I'm done explaining why I came here." Bill calmly says in a serious tone. Once he was sure everyone's attention was on him he continued to talk. "I'll be gone on some business for a total of three day, starting today," Most people mentally cheered in their heads, "Of course I can't bring my favorite little meatsack with me. So he'll be watching you until I come back." Then their mental cheers dropped.

"Why have him watch us? Aren't ya harpies enough?" Gideon asked the demon.

Bill make a 'tsking' noise and shook his index finger in front at them. "Harpies can do so much, they still need to the castle's needs kid. So they can't always take care of you. Right now I'm just telling you this because my watchman is still getting ready, but he should be on his way here now."

The sound of running footsteps rang in the air and finally past through the door. The person who was gonna watch them made everyone freeze.

"DIPPER!" Mabel yelled happily some tears leaking from the corner of her eyes.

Dipper turned in her direction and smiled at her. "Hey Mabel! How are you doing?" He asked like the apocalypse wasn't even happening.

"Kid! You remember us?" Stan says feeling relief on the inside.

Dipper nodded, "Of course Grunkle Stan! Why wouldn't I remember you guys?" He laughed happily.

Bill took of the brunet's hat and ruffled Dipper's hair with a grin plastered on his face. "Well Pine Tree, I'll be back in three days! Be good!" The demon placed the hat back on the kid's head. Finally teleporting out of the room leaving the occupants alone with Dipper.

"Dipper! You have to get us out of here!" Stan yelled to his nephew banging his fist against his bubble.

Dipper snapped his fingers together and everyone was out of their little bubbles.

The first thing the Pines family did was give Dipper a tight hug. Mabel hugged him a little tighter which caused him to push away a bit. When they were done hugging the group turned to everyone.

"If we moved quickly we can escape Bill's castle and find a place to hide for awhile until we can defeat Bill. Come on everyone, let's get moving!" Ford exclaimed and started moving towards the door. Following behind him was the rest of the town.

Mabel tugged on her brothers hand so they could walk out of the prison they were being held in. But didn't move with her. She turned to look at her brother who held his hand up and snapped his fingers again.

Just before anyone could past the door, the entrance quickly slammed shut in front of them. They turned to look at Dipper who smiled kindly at them.

"Bro Bro... What-"

"Bill told me to watch you and make sure you don't get away." Dipper says cutting off his sister. "I intend to keep my promise to him.

+Flashback: Bill's chamber+

Bill held Dipper in a hug. " PineTree, can you promise to not let them go once I leave you with them?"

The burnet nodded and got out of the blond's hold to get ready to see the people of Gravity Falls again.

"I got it Bill, or else I'd be punish for it."

Bill laughed and patted Dippers head. The teen blushed and turned to look at the demon again.

"As long as you promise to-"

•••

What promise?

+Back to the present+

They gave Dipper an unbelievable look on their face.

"Kid your insane!" Stan excalimed.

Dipper kept smiling. "So, what's your point?"

"Your not our Dipper..." Wendy says slowly.

Dipper chuckled. "People are not what they seem Wendy, but I'm merely protecting all of you. Leaving this place means danger. And I'm not about to feed to that monster." He said in a serious tone, he pulled his hand away from Mabel and casually stood in the middle of Bill's wheel.

"Dipper Pines, ya gotta be kidding me here! After all ya told me back near my dear sweet pea's bubble!" Gideon shouted at the Dipper annoyed. Bud Gleeful held his son back from going close to the boy.

Everyone was yelling at Dipper to let them go.

"If you want us to be safe Dipper than you would've stood up to Bill! You would have stood up against him instead of giving yourself to him! Your making a mistake!" Mabel yelled at her twin sadly. She walked right up to him and slapped him across the face.

The room turned deathly quiet when she did that.

Dipper frowned while the shadow made by his hat concealed his eyes.

"You know better Dipper. I know you do." Mabel said to her twin softly. She took Dipper's hand in her own and held it tightly. "People are not what they seem huh? It's funny because your doing it right now with that mask of yours." She smiled at Dipper who was forming a small smile of his own.

This time Dipper's smile was genuine as is his laugh and turned his head to face his twin again. "I really can't disguise myself from you can I?"

Mabel hugged her twin again happily with Dipper hugging her back.

"Dude why can't you just let us out?" Soos asked fiddling with his fingers.

Dipper sighed tiredly. "I can't go against Bill. If you guys remembered I'm basically owned by him. You can't see it, but there's actually a collar around my neck attached to a chain." He ran his hand over his neck without knowing he was actually doing it.

Wendy went over and patted her friend on the back. "Your really having it rough man. I wish there was some loop hole in your deal to break you free from him." She says.

"I may not be able to let you guys leave the castle, but your still free to roam in it. Just please don't go where there are red triangles on the door. I seriously don't want to get you guys in trouble." Dipper tried to cheer them up only helping a bit.

Ford nodded. 'At least we can still move around the castle and find possible escape routes' The man thought.

"Hey bro bro?"

"What Mabel?"

"Why do you kiss Bill on the cheek all the time?"

Dipper blushed cherry red and stuttered. "I-It no-thing! It doesn't mean anything... I don't know, it just automatically happens. I'm not sure why, but it just feels normal I guess."

"The sooner we can hold Bill down and close the rift we'll all be safe. We have three days to plan." Ford says cutting off the topic about Dipper kissing Bill on the cheek. "The prophecy states that Bill can be maintained by his ten symbols on his wheel, but we can hardly do anything to him."

Pacifica stepped up. "Is there anything in that dumb prophecy he keeps talking about that helps us?"

Ford thought for a moment and his eyes widen after realizing something. "If I remember correctly, the prophecy did mention having someone to help the ten symbols control Bill.

"Wait, control Bill? You gotta be kiddin man! That weird triangle thing is to powerful, it's impossible!" Robbie exclaimed clenching his hands into a fist.

Ford shook his head in disagreement. "Oh, but it is possible. It says that Bill has a balance partner who equals him out on a scale. Technically those two get along just fine together after a certain period of time, but their personality doesn't change so much. If we can find Bill's balance partner than we can still manage to save the world!" The man explained to everyone.

"So it's like opposites right?" Mabel asked her great uncle Ford.

Ford nodded. "Exactly!"

Mabel grinned and pushed her twin to Grunkle Ford. "Well opposites attract as they say! Dipper, don't hate this girl now because apparently she just figured out your Bill's balance partner!" She giggled.

"WHAT!?" Everyone exclaimed.
