(A/n: Sorry that I haven't posted in awhile!)

You and Bill finally arrived at the Shack.

As you entered the house you saw something weird. There was a random pig waddling around the house. "Ahhh!!! PIG!" Bill yelled as he jumped onto your back. "Bill?" You looked over your shoulder, "Its just a pig." You say as you pick up the big and hold it. The pig oinked. "ITS CALLING ITS MONSTER FRIENDS!!! GET IT AWAY FROM ME!!!" Bill yelled. "Alright, alright. I'm putting it down." You set the pig softly on the ground.

Your boss from your job saw the whole thing. "Not even gonna ask." He turned then walked away. After he was gone you looked over your shoulder at Bill, "You can get off my back now." "Oh, sorry." Bill apologizes as he hops off tour back.

"Y/N!!! WILL!!!" Mabel yelled as she ran over to the two of you and pulled us into a big bear hug. "I missed you guys so much!" Mabel let go of the two of you. "Hey, where's Dipper?" You ask. "And why would you want to know?" Bill looked at you as if he would break all of Dipper's bones if you liked him. "No reason." You smile cautiously. "Oh, he's in the attic in our bedroom!" Mabel says, ignoring everything you and Bill had just said. "Cool! Race you up!" You ran up the stairs carrying your stuff. Mabel ran behind you with Bill running behind Mabel.

"Haha!" I win!" You yell out of breath as you collapse onto the floor. "If you wanted to see him so badly why are you laying on the floor?" Bill asked. You rolled your eyes, before Bill grabbed your ankle and dragged you into the bedroom.

"Dipper! They're here~" Mabel said in a singing voice. "Yeah, whatever." Dipper said not looking up from his book.

You and Bill recognized that book. It was Journal 3! Bill dropped your ankle as he slowly walked towards Dipper. "Whatcha reading?" Bill asked. "A, uh, book about, uh, history? Its a history book." Dipper lied. "Alright." Bill shrugged before getting up. Bill actually sneaked a glance at the book. It was totally Journal 3, of it wasn't obvious by the cover.

"So what are we doing first?" You asked. "How about... Hm..." Mabel had to think, "What if we set up your guys' beds and then we'll put make up on the boys. And possibly play truth or dare." "Sounds like a plan!" You and Mabel fist pumped. The boys didn't hear the part about the make up part.

After setting up the beds, you all decided to change into your pajamas first before playing the games and the activities.

"Hey, your matching pajamas are cute!" Mabel smiled. "Yeah, sure but the pattern looks familiar." Dipper looked at what you and Bill were wearing. "Uh, it must be a popular design then." You try to get his mind away from the thought of Bill.

"So! What now?" Bill asks. "Truth or Dare?" Mabel suggests. "Okay!" You, Dipper and Bill say at the same time. You all sit down in a circle on the floor of the bedroom.

"I'll start!" You smile, "Mabel. Truth or Dare?" "Dare." Mabel says confidently. You smirk then look over to the boys. Without taking your eyes off of them, that smirk never leaving your face, you say, "Mabel, I dare you to put makeup on the boys." Bill's and Dipper's eyes widen in fear. "Well, Y/n. I dare you to help me." Mabel grabs her make up kit and brings it to you. The boys try to run but you jump on top of them, pinning them down to the floor. Mabel grabs a rope and ties the two boys up.

After struggling for a while there make overs were done! You did Bill while Mabel did Dipper. You actually only did a little makeup on Bill since he had some on to pretend he was Will.
You untied the two boys and they were extremely grumpy. Mabel held up a hand mirror for them. They both impressed at how they looked... Before they washed it all off.

"Okay, my turn. Uh, Will, truth or dare?" Mabel asked. "Dare." Bill said. "Go in the closet with Y/n for 10 minutes." Mabel dared. Bill smiled while you rolled your eyes.

You both got in the closet.

"So what now?" You asked. "Make love?" Bill asked. "No. Plus there's other people right outside of the closet." You say. "Please, please, please! At least let me finger you." Bill begged.

Good thing Mabel and Dipper couldn't hear you from out there.

You didn't want to give in to Bill, yet you really wanted to. "Fine. But we only have ten minutes. So lets do this quick!"

Outside of the closet:
"What do you think they're doing in there?" Dipper asked. "They're probably just talking about how amazing of friends we are." Mabel answers with a smile. "Yeah, but Will seems sketchy and I know I've seen the pattern of their pajamas before." Dipper says.

Dipper walks over to his journal and opens it. He flips through the pages and the spots something, "Ah-ha! Mabel, look. I knew I've seen that pattern somewhere." Mabel runs over to see the page Dipper is on. "Its the pattern of Bill!" Mabel says. "Sure, Y/n is friends with him, but why would Will be okay with his girlfriend being friends with a demon?" Dipper thinks out loud. "Wait, Bill... Will!" Mabel's eyes widen in realization. "That means... Will is-" Dipper gets cut off by the timer going off.

"Alright. The time stopped. You guys can come out now," Mabel calls out to her 'friends?' What are you and Will(Bill) even are to Mabel and Dipper?

The doors open and you stumble out, in the result of falling onto Mabel's bed. He hit you up good. "She's fine. Just, uh, her leg went numb while we were in the closet." Bill lies. Mabel and Dipper slowly back away from 'Will'.

"Uh, what's wrong guys?" Bill asked as he took a step forward, towards the two. You looked up to see Dipper and Mabel backing away from Bill.

"Y-Your wrong!" Dipper said. "Well, that wasn't very nice!" You yell at Dipper. "Get out of our house you one eyed Dorito!" Mabel yelled. Bill looked over to you and you looked over to him. They had figured it out.

"Fine. You caught me." Bill turned back into a Dorito, sorry, I mean, he turned back into his triangle form. "Y/n! Run! Bill tricked you into being his girlfriend. Get out of here while you still have the chance too! We'll fight him off!" Dipper yelled.

Bill just looked at you and you looked at him..... You both broke out laughing. "Oh, yeah, that's rich." Bill wiped away an imaginary tear. "Bill never tricked me. We, uh, we are actually dating. Bill kept on bugging me to either stay home or for him to come with me to work. So he ended up coming to work with me. Then you two came over and asked about Bill. We knew you wouldn't trust me anymore, and your guys are the only friends I have so, I didn't want to risk losing you both. We both lied about Will, even though he's a real person." You explain. "Wait, Will is a real person?" Mabel asked. "In Reverse Falls. Where everyone's personalities switch so I would be a scaredy cat, which Will is, Y/n wouldn't be her loveable self, you both would be evil and ect. for everyone else. Also the names were switched like how my Reverse Falls name is Will." Bill explains as he floats around in the air, with his hands behind his head, leaning back.

"And you turned into a person? Explain." Dipper said. "Yeah! Explain, Cipher!" Mabel yelled. "Yesh, Shooting Star, calm down." Bill says before turning into a human. "Well, Y/n, didn't trust me at first, so I turned into a human. The more I bugged her as a human, the more she trusted me." Bill walked towards the two. This time they weren't backing up.

"Then you two fell in love!" Mabel asked with a giant smile on her face and stars in her eyes. "She's all about people, and demons, mainly the people part, falling in love." Dipper explained. "Ah." You nodded. "And to answer Shooting Star's question, yes then we did fall in love." Bill looked over at you. "Woah, woah, woah." You said as you got off Mabel's bed, "You fell in love first." "First off I read your mind, remember? Second, you kissed me first." Bill listed the hints that showed you fell in love with him first. "What does reading her mind have to do with this?" Dipper asked. "When I read her mind, I found out that sh-"You covered Bill's mouth. "Heh, yeah, he read my mind and thought what I was thinking meant he was in love with me." You giggle nervously. "Aww, you're so cute when you giggle while you're nervous." Bill goes and pokes your cheek. "Hey, stop poking me!" You push him away.

"Awww! You two are so cute!" Mabel squeals over you and Dorit- I mean, Bill. "Thanks." You smile. "I don't approve." Dipper say. "I'm sorry, what?" Bill started to get angry. "Bill, calm down. The funny thing is, you don't have a saying in our relationship. Plus you sound like a dad who doesn't approve of his daughter's relationship." You smirk. "Whatever. But I still don't like it." Dipper crossed his arms.

Then suddenly someone walked into the room. "Kids. I heard yelli-" It was Stan but once he saw Bill he stopped. "What are you doing in my house?" Stan asked Bill. "Uhh... Leaving!" Bill said as he grabbed your hand and ran out of the shack with you following.
