In 2 days he was going to get his powers back. Bill looked at the night sky through his window. He felt trapped in his room and decided to get some fresh air. He climbed out the window and onto the roof.
"You couldn't sleep either?" A voice asked.
Bill nearly fell off the roof.
"Don't scare me like that Shooting Star." He said scooting over to her.
"Sorry." She said, staring at the moon. "Why are you up?" She asked.
"I have a lot on my mind." Bill said.
"Me too." Mabel said.
It was silent for a while.
"I have to tell you something." They said at the same time.
They both laughed. "Ok you go first." They said at the same time.
"No you go first!"
"No you go first!"
"Ok, ok! I'll go first." Bill said. "I-I...Mabel I...I..." Bill stuttered. "I want to stay, I want to be a human, I want to age! I want you! I love you Mabel Pines!" He said. He quickly slapped both hands over his mouth and hid his head in his arms in embarrassment.
Mabel looked at him.
He was sitting there, his shaggy blonde hair a mess.
He was leaving in 2 days.
He was a dream demon.
He was perfect.
A million thoughts were rushing through her head when she said those four words.
"I love you too."
Bill looked up. "What?"
"I love you Bill Cipher." Mabel repeated.
Bill just stared at her. "Y-You do?"
She nodded.
"But I'm a dream demon! I'm leaving in 2 days Mabel, 2 days! For all you know I could be manipulating you or something! Mabel this isn't right I'm a triangle, a dorito, a corn chip, a-" He was cut off by Mabel.
By Mabel kissing him.
He was shocked at first but he melted into it.
Mabel ran her hands through his shaggy, blonde hair. She mentally laughed when she thought of what Dipper's reaction would be. She broke the kiss.
"I don't care that you're a triangle dream demon." She said.
He just stared at her.
"A-Are you sure?" Bill stuttered.
"I'm sure." Mabel said. "Now you have to stay here."
Bill nodded. It was like he couldn't talk anymore.
"Now, let's get back to bed." Mabel said. "Dipper is going to freak if he hears us."
The thought of Dipper made Bill shiver. "Y-Yeah we probably should." He said.
"Goodnight Bill." Mabel said kissing Bill on the cheek.
"Night Shooting Star." He said climbing through his window.
He silently cheered to himself once he got back in his room.
He plopped down onto his bed.
"Maybe being human isn't that bad." He whispered to himself.
"WHAT?" Dipper shrieked.
Bill shuddered. This was not going to be good.
Mabel came into the room. "He wants to talk to you outside."
"O-Ok." Bill said as he quietly walked out of the Shack, trying not to notify Stan that he was there.
"Hello Bill." Dipper hissed.
"Hi." Bill squeaked.
"So you and my sister have something going on?" He asked.
Bill cleared his throat and had a sudden burst of confidence. "Yes. Yes we do." Bill said.
"Well I want you to NOT have a thing with MY sister." Dipper said.
"You see Pine Tree, it's not that simple." Bill said. "She's beautiful, caring, funny, stubborn, persistent, adventurous..." Bill kept ranting about Mabel.
Dipper took all of this in. Bill really loved Mabel. Dipper looked up at Mabel, who was watching from the window.
"She's everything I have! She-"
"Bill!" Dipper interrupted.
"What?" Bill asked.
"Just...just don't hurt her." Dipper said.
"Woah, woah, woah hold up." Bill said. "You're actually letting me do this?"
"Yes. Just don't do anything that I wouldn't approve of." Dipper said.
"Yes! Thanks Pine Tree!" He said going inside. He walked into Mabel's room. "Shooting Star, he said-"
"He said no didn't he? He always says no! Ugh I mean, I get it you're a dream demon but-"
"He said it was fine." Bill said cutting her off.
"WHAT?" Mabel shouted. "HE DID?"
"Um...yeah." Bill said.
"Oh my gosh!" Mabel said running own the stairs. "Dipper, Dipper thank you!"
Bill watched through the window as Mabel tackled Dipper in a hug. Bill laughed. "Don't kill him Shooting Star!" He said.
"Oh thank you, thank you!" Mabel said to Dipper.
"No problem Mabes, but can you get off of me?" Dipper asked.
"Of course!" Mabel replied jumping off of Dipper.
"So Mabel...do you really love him?" Dipper whispered so Bill couldn't hear.
Mabel blushed a deep scarlet. "Yes. Yes Dipper I do."
"So is he staying?" Dipper asked.
"I want him to." Mabel replied.
"But what about Stan?" Dipper said.
"Maybe he can get his own house! And around Stan we'll call him William!" Mabel suggested.
"That could work." Bill said coming out of the Shack.
"Then we'll try?" Mabel asked.
"Anything for you Shooting Star." Bill said.
"So, let's go introduce you do Stan!" Mabel cheered.
"R-Right n-n-now?" Bill stuttered.
"Yup! And there's nothing you can do to stop me!" Mabel said running in. "Oh Grunkle Stan!"
Meanwhile, Bill was pacing the front yard. "Oh no! What if Stanford finds out that I'm Bill! The corn chip dream demon! He'll kill me!" Bill shouted.
"You might want to quiet down." Dipper said.
Bill looked horrified. "What if he heard that?" He shrieked.
"Bill calm down! It's not like he even knows you!" Dipper said.
"That's were you're wrong Pine Tree. Me and your Grunkle go way back." Bill said.
"What? How? Why?" Dipper asked.
"Well-"
"Who is this boy you're talking about?" A rough voice said.
"This is William." Mabel said, pointing at Bill.
"Hello and stay away from my great niece." Stan said.
"E-Excuse me?" Bill stuttered.
"I don't want any boys with her except Dipper and me." Stan said.
"But Grunkle Stan!" Mabel whined.
"No, I would like to talk with William." Stan said.
Bill gulped. "S-Sure."
They walked inside and Stan closed the door behind them.
"S-So-AHH!" Bill shrieked because Stan had tackled him. "H-Hey what are you doing?"
"I know who you are Cipher!" Stan hissed.
"Ah so you know Stanford?" Bill smirked, his demon side coming back to him. His powers would come back any second now. "How about we make a deal?" Bill said knowing he could break it since he didn't have his powers yet. "I'll leave once I get my powers back." Bill said. "Deal?"
"Deal." Stanford said, shaking Bill's hand.
Of course his powers came back right when he shook his hand.
OOO! What a twist! Of course this won't end with him leaving. It will end with something else I'm planning. MWAHAHAHAHA!
