(Y/N) POV 

It was the next day, and I was hanging out with the Pines again. I was just laying down on the counter, groaning from boredom. Mabel and Dipper went to a family 'meeting' with Ford. I start to lace my fingers together, as Mabel runs into the room holding her cell phone. 

"(Y/N)! We are going to look for unicorns!" Mabel shouts.

"Who is 'we'?" I question.

"Me, you, Candy, Grenda, and Wendy!" 

"I haven't met Candy or Grenda. What are they like?" 

"Just like me! But different!" Mabel gleams.

I giggle at her words, and she laughs with me. "I guess I can't say no to Mabel." 

"That's the spirit!" 

I slid off the counter as Wendy walks into the room. She gives me a thumbs up, and a thumbs down. I stick my thumb up and nod, and I hear a sigh of relief come from her. I chuckle and put my phone in my back pocket as Mabel finishes up her phone call and hangs up. Mabel grabs my hand and runs out the door.

"Mabel! We have to wait for Wendy!" I say, pulling her to a stop.

"Oh yeah!" She shouts, turning around.

Wendy jogs up to me and Mabel. She has her axe on a belt she's wearing, and tails behind us.

-time skip-

Candy, Mabel, Grenda, Me, and Wendy after about an hour, found this unicorn palace place. Mabel being the most 'pure of heart person' steps up to the unicorn. I just stand there awkwardly, looking around the weird place. There's a waterfall, and it has this tall-

"(Y/N)! We're leaving." Wendy snaps, taking me out of my trance. I nod my head in response and walk out with the other girls.

"Come on Mabel, don't beat yourself up over this. Besides, I wouldn't trust a horse that wears makeup." 

"Unicorn." I correct Wendy, sticking out my tongue.

"Yeah, let's forget about that stupid dumb unicorn hair." Candy grunts.

"It's not about the unicorn hair any more girls, it's about me!" 

"Mabel," I say, making her look at me. "I know you care about your reputation, but protecting the shack is important too, don't forget it."

She nods her head, and Candy gives me a thumbs up.

"What are we waiting for? Let's get started!" Grenda says, and we all cheer.

Us five go out to the town and start doing good deeds. From planting trees to giving tips, washing cars, giving blood for blood drives, helping old people cross the street, and the list goes on. We finished when it was about four, so we go back to the fortress. 

"When that unicorn sees my heart, so going to say I'm one-hundred, positively-"

"NOT PURE OF HEART!" The unicorn stomps down on the ground with her hooves.   

Mabel does a happy dance, then realizes that the unicorn said no.

"Doing good deeds just to make yourself look better isn't better at all! Also your crushing about ten dandelions, which are basically children's dreams." The unicorn snorts, flipping its mane. 

Mabel runs out crying, and the girls follow her. 

"You have a horrible personality!" I yell before going out and looking for the girls. I catch up with them, but Mabel is laying down on her side, with a frown. I go to ask if she'll be alright, but Wendy stops me and tells me a plan to take the unicorn's hair without Mabel and the unicorn knowing. 

It feels so wrong and right at the same time. That's what it felt like when I was kissing Bill. Bill... Bill! Wasn't I supposed to meet up with him today? Oh, shoot!

"Girls! I gotta run, I forgot I'm uh.." I say, thinking of an excuse. "I told my mom I would help her with... Dinner!" 

"Oh, okay then!" 

I let out a sigh of relief and walk back to the shack to make sure I didn't leave anything at the Shack. Don't get me wrong, I trust the Pines. I don't think they would steal anything or hide anything from me. But, just in case, you never know.

I open the screen door and walk in. The first thing I notice is that the vending machine door is wide open..? 

Out of curiosity, I peek inside of the door, only to find a creepy set of stairs. I step out, and take a deep breath, and start to walk down the stairs. I walk carefully, seeing how the stairs look like they are about to collapse. I reach the bottom, to find an elevator door. I look closely at it, and there seems to be three floors.

I press the button to go down, cause I can only go down. The only way is down. 

The doors open with a ding, and I step inside for a closer look. I'm not really scared, just interested. Was this behind that snack machine the whole time? Whoever did that was playing their cards well. I press the number two button, and the doors close. It goes down quickly and quietly, making the curiosity drop some. 

The doors open again, and the scene in front of me is confusing. Ford and Dipper? What are they doing down here? 

"Bill wasn't always my enemy Dipper. I used to think of him as a friend, but now.." Ford trails on.

I step out of the doors quickly and hiding behind some boxes.

"I hit a roadblock in my investigations of Gravity Falls. I soon found this cave that had some ancient writing in it. It told me not to read it, but I was desperate. I read the inscription aloud, but nothing happened." Ford blabbers on.

I would have left by now, but considering I heard Bill's name, it made me stay.

"I met a being in my dreams Dipper. You know, Bill Cipher." 

I clench my fist and exhale. 'So has he been lying even more to me?' 

Ford explained the whole story to Dipper, and basically me. I..I couldn't believe that he was actually a dream demon? That doesn't make sense!

"Wow," Dipper says.

I move out of my hiding spot and walk up to them. "You're not the only one who's been lied to by Bill, Ford." 

They both jump and look at me.

"How long have you been down here?!" They both say.

"That doesn't matter, but I'm serious. Bill has been tricking me for the past three years."

"How so?" Ford asks, clearly interested.

"It was the end of the school year three years ago, and I go to this waterfall where I live," I say, remembering like it was yesterday. "Bill was there too, and we just became friends." 

"How did he show up? Didn't you find it a bit odd he was a triangle?" Dipper asked.

"That's the thing, Dip. He didn't tell me he was a triangle or a demon. He was.. Human. I swear, he looks just like somebody passing by on the street." I say, using my hands to show how real I was being.

"Strange. Could we talk about this sometime? Not now, but maybe in a couple of days, we could talk about Bill?" Dipper asked.

"Sure. I can tell you everything I know about him and his human form."   

"Very well. You two should go upstairs now, I need to clean up this mess." Ford says, sounding like an order.

Me and Dipper race to the elevator doors, and go upstairs.

I hope Mabel is okay. 

But most important thing I need to do. 

Talk to the liar, Bill Cipher.    

Annddddd... That's what I was writing! I meant to write this earlier, but that didn't happen. Here it is now, though!
