I DO NOT OWN GRAVITY FALLS

Dipper is peacefully sleeping in his room in the mystery shack. The last day of school was yesterday and he's decided to sleep in. Pacifica also has the same idea. She has Dippers arms wrapped around her like a meat blanket. Suddenly, Mabel bursts in wearing a jokey mask holding a fake plastic chainsaw. "SUPRISE!"

Both Dipper and Pacifica fall out if the bed. Mabel takes off the mask. "Your faces."

Dipper stands up and starts whacking Mabel with his pillow. "What the hell Mabel?"

"Summerween is in a few days Dipper. I just came to say that I'm gonna be matching with Bill, we're going as cops and robbers."

"Is that the only reason?"

"Well I also wanted to scare you."

"Just get out."

"Ok, if Bill knocks tell him I'm getting changed, he's gonna be here in a few minutes."

"Ok, now get out."

Pacifica stood up and sat on the bed. "Speaking of summerween, what are you gonna go as Dippy?"

"Please don't call me that. I'm not sure, maybe one of the doctor's."

"Pardon?"

"You know, the Doctor, from Doctor who. I like Peter Capaldi, but I think I'd look better as Matt Smith."

"I always liked Christopher Ekelston myself. If you go as Matt Smith, I can go as River song. Then for one night I'll be your wife, not your girlfriend."

"I like it. We'll have to start working of those costumes right away. We only have a few days."

Meanwhile, Mabel was getting changed in the next room. She had gotten out of her PJs and had put on her underwear. Without thinking she reached for and put on her enchanted necklace. Bill appeared in the room. He looked over at Mabel. "Hey babe, looking good. Is this our new thing, because I have a lovely pair of yellow boxers I could wear. Pink is a great colour for you, I like it." He chuckled.

Mabel jumped a mile and tried to cover herself with her hands. "Bill, what are you doing in my room?"

"You put on the necklace. When you do, I appear."

Mabel looks down at her neck. She had indeed put it on. Mabel scrambled to put a top and skirt on. "Well, I'm glad your here. I missed you after the party yesterday. One of these nights I'm gonna keep this necklace on so you can stay the night." She hugs him.

"I'm looking forward to it."

"You're gonna need to sneak downstairs though and knock on the door. I cant have you just appearing in my room. Dipper might work out who you are."

"Ok, I'll head down there now." Bill opened up Mabel's window and jumped out. Mabel ran to the window and saw Bill slowly float down to the floor. He winked at Mabel and walked his way to the front of the house. He knocked the door. Dipper and a now dressed Mabel walked down the stairs. Dipper opened it. Bill was standing on the other side. "Hey Dipper."

"Hey Bill." Dipper out his hand out to shake Bills hand. Bill looked over to Mabel with a worried look on his face.  Mabel started to cough. "You can *cough* touch *cough* Dipper."

Mabel's necklace momentarily glowed blue, before returning to normal. Bill smiled and shook Dippers hand. He then walked up to Mabel. "Hey babe."

Mabel hugged him again. "Hey Bill."

"Before you say anything, yes I'll do the cops and robbers thing, but only if I'm the cop."

"Why do I have to be the robber?"

"Because you already stole my heart."

"Cheesy. I like it."

Dipper walked up behind Bill and tapped him on the shoulder. "Hey Bill, I have to ask, how old are you? You look a bit older than me and Mabel."

"I'm that much older. You and Mabel are 14, I'm 16."

"Oh, ok. You look older, but that'll work in our favour eventually."

Pacifica calls down from upstairs. "Dipper, I need a hand. You want your fez to be authentic and you have no idea how hard it is to sow felt."

"I got to go, it's great to see you again Bill." Dipper walks upstairs.

Mabel leads bill up to her room. "Were you telling the truth about your age just now?"

"Well, I'm 16 million dreamscape years old, that equates to about 16 of your earth years."

They got to Mabel's room. "But didn't you try to take over fords mind like 20 years ago?"

"That was my dad. I'm not the first Bill Cipher. Weirdmagedon was my fault, but I was all hopped up on teen demon hormones and it made me a bit crazy."

"So you really are 16?"

"Yes."

"Good, because it would feel weird making out with a 16 million year old." Mabel launched herself into a make out session with Bill. He lost his balance and fell on the floor. When they had finished Mabel rolled off of Bill, both of them laughing. Mabel wiped a year of mirth from her eyes. Bill put his arm under her and she curled up next to him. "So, about these costumes."
