"No!" Bill shrieked.
"Haha! I win Cipher!" Stan declared. "Now leave."
"B-But I c-can't l-leave!" Bill stuttered.
"Did I ruin your plans Cipher? Were you trying to kill my great grand-niece and nephew?" Stan asked.
"The exact opposite Stanford." Bill hissed as he got up. "But...a deal is a deal." Bill said sadly. "And I can't break it." He walked outside with Stanford. "Hey guys."
"B-Will!" Mabel caught herself trying to say Bill.
"He said that I have to go." Bill said showing her a blue flame in his hand.
"But you can't leave! You promised!" Mabel said stating to tear up.
"I promised I would leave once I got my powers back Shooting Star." Bill said, a single tear running down his cheek.
"But...we just...don't leave!" Mabel said hugging Bill.
"Wait, Mabel you knew this was Bill Cipher and you didn't say anything?" Stan said.
Mabel ignored him. "You can't go." She whispered.
"Yeah dude, I was just starting to like you." Dipper said. "And Mabel likes you a lot."
"I love you Bill." Mabel whimpered.
"I love you too Mabel." Bill said. "But I have to go now."
Mabel quickly kissed him on the cheek.
"Goodbye." Bill said.
"See you later." Mabel said.
Bill sighed. He knew he wouldn't be seeing her anytime soon. "Stay beautiful."
And with that he left.
Mabel ran up to her room, buried herself in sweaters, and cried.
Through her sobs, she heard Dipper yelling at Grunkle Stan. She slowly crawled out from her sweaters and looked out the window. She saw Dipper storming back into the Mystery Shack. She got back into her sweaters.
She had just told Bill that she loved him and then he was forced to leave.
She heard the door open. "Mabel?" Dipper said.
"Mabel's in Sweater Town." She groaned.
"How about Dipper's Hugs Town?" Dipper asked.
Mabel stuck her head out of all the sweaters and ran into Dipper's arms. "Why'd he have to go?"
"Because of Stan." He hissed.
"He'll come back." Mabel said. "I just know it."
1 week later
"Welcome to the Mystery Shack!" Mabel said with a huge fake smile.
Dipper noticed.
"Mabel you don't have to work if you don't want to. I'll cover for you." Dipper whispered.
Mabel looked at him. A tear slid down her cheek. "Thanks Dip."
She ran upstairs and looked out the window. She swore one of the clouds looked like the triangle form of Bill.
1 month later
"Come on Mabel! Let's go on a mystery hunt!" Dipper called.
"Ok..." Mabel mumbled as she walked down the stairs.
"Come on Mabel, lighten up!" Dipper said. "Mystery Twins?"
Mabel laughed. A true laugh. "Mystery Twins." She confirmed.
"Let's go!" Dipper said. They ran out the door.
Mabel looked back at the Shack and saw a triangle-shaped window staring at her.
6 months later
Mabel was falling into her slump again.
"Mabel! He would want you to move on." Dipper reasoned.
"I know but...I can't" Mabel said.
"Mabel..." Dipper said putting an arm around her.
"I'll try." Mabel said.
"That's the spirit!" Dipper said.
Mabel put the yellow triangle sweater down and walked out the door.
8 months later
"You have feelings for someone else!" The boy shouted.
"N-No I don't!" Mabel stuttered.
"Mabel." The boy sighed. "It's ok."
"But Dallas! He's gone! He's not coming back!" Mabel tried.
"Mabel." Dallas said grabbing her shoulders. "It's for the best."
Mabel sighed. "Ok."
"Bye Mabel." Dallas said.
"Bye."
It had been almost year and she still hadn't gotten over Bill.
