Gravity Falls X Female Reader

Weird Mageddon

I was just watching TV when Mabel ran down the stairs crying and out of the house. I ran upstairs and said, " Dipper, why is your sister crying?"
"I'm staying in Gravity Falls to be Ford's apprentice." He said quietly. " You're WHAT!? I can't believe you. Listen... I've seen some pretty amazing things, but nothing as amazing as you and your sister. Now, she's gonna grow up without her favorite person in the entire world. You know what, I'm going to talk to Ford about this. " I walked to the gift shop which was empty. I opened the door and stormed down the stairs and into the elevator.
When I got inside his lair I said," You owe me a explanation, Stanford." He turned around and said, "I know that you are very upset with me, but I can explain."

I walked outside to see a giant rip in the sky and Bill. "Holy s**t." I muttered. I ran to find an unconscious Mabel and Blendin a fourth of a mile away from the shack. "What the heck happened?" I said as knelt beside Mabel. "It was Bill Cipher not me, I'm telling the truth." Blendin replied.
All of a sudden, Mabel was floating and enclosed by a bubble with the shooting star from her sweater.
