Bill's P.O.V
--------------------
I got next to mirror to check myself. I got the bow tie, the top hat. Yeah, I'm good, but I'm gonna have to look even fancier for tonight. It's time for the bigger tie and hat. I got the bigger tie and hat on myself, checked myself in the mirror, and found Pyronica beside me.

"AHHH! GEEZ! WHAT ARE YOU DOING HERE!?"

" *mockingly*  "Uh, I can go to the dance with you Mabel. Let's kiss under the bloody moon while drinking sparkles." "Ugh. Pyronica, sometimes you boil my blood.

"Yeah, yeah, mock me all you want. Just don't tell any of the Henchmaniacs. You know they'll resent me if they know."

"Yes sir!"

Mabel's P.O.V
--------------------

I got 2 sweaters ready for the occasion. One of them said "I'm being watched", while the other said "I'M WATCHING YOU". They both were yellow sweaters with plastic eyeballs pasted all over it. Plus, GLITTER!

"This outta make Bill so happy."

"You rang?"  I got shocked by Bill's sudden appearance.

"AHHHHH!" I stuffed Bill inside the "I'M WATCHING YOU" sweater in self defense.

"AH! WHAT IS THIS!? IT'S....so....nice...and fluffy." Bill seemed to being liking his new sweater.

"It's a sweater, Bill. It's the thing I wear all the time." I'm surprised that Bill didn't know what a sweater was after all this time.

"Well, I like it. However, you might want to wear another sweater. Don't want your family getting on to me." Ok, so maybe I should listen to Bill. Ford and Dipper were also attending the party, so wearing a shirt with a saying of Bill's on it wouldn't be all too normal. I got my Shooting Star sweater on.

"Alright, Cmon Bill, Let's go! We got a party to celebrate!" I grabbed Bill by the arm and took him downstairs. "Wait..." I screeched to a halt. "If I'm the only who can see you, how do I bring you to the party?" Bill just snapped his fingers.

"There. Now everyone can see Me. Happy?" I just smiled.

"Yes. Yes I am."

I introduced Bill to Candy and Grenda.

"Bill, this Candy and Grenda, my best friends. Candy and Grenda, This is Bill, my boyfri-" Bill put his hand over my mouth.

"We're comrades." Bill tried to slip it under the rug, but his red edges said other wise.

"You're...interesting, Mr. triangle." Candy seemed a little uncomfortable around Bill.

"Just call me Bill. Though, Mr. triangle does sound like a good name." Bill stuffed some popcorn in his eyeball. We soon spotted Dipper and Pacifica. 

"Ah, llama and pine tree are having a nice little time." Llama? Who's llama?

"You mean-" Grenda was cut off.

"Pacifica Elise Northwest. Most popular kid in Gravity Falls, highly insecure about her parents and family history, and having a romantic relationship with....Oh...nah...I should keep that secret."  Grenda seemed shocked about Bill's knowledge.

"H-how do you know all that?" Bill's eye just made a happy gesture.

"Oh, I know lots of things."

Third Person P.O.V
---------------------------

Bill turned towards Candy.

"You're slightly sensitive about the fact that you're foreign." Another Bill came out from behind Bill and turned toward Grenda, shocking the girls.

"You're really sensitive about you're weight." Another Bill came out, turning towards Mabel.

"Your silly nature is just a cover for your insecurities." Bill just turned into as many clones as there was as many people at the party, which was a surprisingly low amount.

"Boys, you know the drill" The Bill's then spread out, naming random facts about the person they came across, confusing everyone at the party. It kept going on until one Bill came across Ford, who was in the hallway, waiting for the bathroom to open.

"You're secretly think highly about You're brother because you know he wouldn't have fallen for my Con-man skills." Ford spat out his drink and got out his quantum-destabilizer.

"WHAT ARE DOING HERE,YOU TRIANGULAR DEMON!?" The Bill clone panicked.

"UMMM....I'M JUST AN ILLUSIOOOOONNNNN......" The Bill clone faded away like a mirage. Ford rubbed his eyes, and just assumed it was a hallucination made by his crumbling mind. Meanwhile, the Bill clone used his tie as a walkie talkie.

"GUYS! OUR COVER IS BLOWN! GO! GO! GO!" The other Bill clones had panic attacks and just overreacted, proceeding to run trough walls, crash through floors, exploding, etc, etc.

Mabel's P.O.V
---------------------

"See, I know lots of things." Well...that was something. But hey, That's the type of thing I like Bill for.

"Well Well Well. Look who's here?" Uh oh. Pacifica incoming. "Is that Dorito your date? Heh. Guess I should expect that with some silly, dumb people like you." Man, Pacifica is such as jerk. Pacifica just laughed as she walked away, before Bill started talking to her.

"I know you, llama." Pacifica paused before looking back. The whole party went silent.

"Um, excuse me? How dare you name me after some farm animal!?" Bill's eye just curved into a happy look.

"Oh, I'm sorry. I know you, Pacifica Elise Northwest." Bill started floating from his chair.

"How do you know me? We haven't even met." Bill loomed over Pacifica ominously.

"Every night, Your parents summon me, and every night, they ask for the same thing. Money. Fame. Riches. Power. And in return, They make a portal to help me enter this world." Symbols started appearing on Bill's eye as he listed the Northwest's wishes. "And every night, your family says the same thing about you." Bill's body turned into videos of Pacifica's parents, with them saying horrible things about Pacifica.

" "Why don't you just throw out the trash?". "Just get rid of our cyst in our family.". "Why don't you just get rid of that useless object?". "She's useless.". "She's weak.". "Why don't you just get rid of her?"." Pacifica had a sad look on her face, and I just looked at the feed with shock and horror. Pacifica's parents talk about her like that!? YOU DON'T JUST TALK ABOUT YOUR CHILD LIKE THAT! Man, I feel so bad for Pacifica. I've also called her some mean things back at our golf war. I probably just made her feel worse.

"Y-YOU'RE LYING!" Tears started forming at Pacifica's eyes.

"Oh, no. No no no no no. I appreciate you kid. You rebelled against your parents. Reminds me of me. I would never say anything like that about you in a thousand centuries. That was your parents." Pacifica pinned Bill to a wall.

"MY! PARENTS! DO! NOT! TALK! ABOUT! ME! LIKE! THAT!" Pacifica was crying and yelling now.

"YES THEY DO! IN FACT, THEY WANT ME TO MURDER YOU SO THEY DON'T TAKE THE BLAME FOR CHILD MURDER!!!!!" The whole room went silent. Pacifica ran away, and Bill just transported outside. Dipper ran towards where Pacifica was ran, and I ran too.

We found Pacifica crying in the hallway.

"Hey...Pacifica...are you okay?" Dipper tried to comfort Pacifica.

"It's true..."

"What is?" I asked.

"My parents were always mean to me. My father rang bells whenever I went against him. But I never though he hated me." I was horrified with what I heard. "You guys are so lucky. You have 2 uncles who love you and should do anything to protect you. My family would care less if I died." I tried comforting Pacifica.

"Look...Pacifica. Your parents are just stinky poop heads who only care about money and fame. But you aren't your parents. Your insides are full of lovely bubbles and nice unicorns." Pacifica started smiling. Dipper spoke up too.

"Yeah. Look at what you've done. You let the citizens in to the party that they desperately wanted to go into. You saved the people inside the manor after that ghost attack. You restored your family name. You're nothing like your parents. Far better than them." Pacifica wiped a tear from her face.

"Thanks you guys."

"Cmon you guys. You have a party to attend to." Dipper and Pacifica walked hand in hand to the party. I admit, Dipper and Pacifica are cute together. Meanwhile, I got someone else to comfort.

I found Bill hiding inside his hat,banging him self against the wall.

"Uh...Bill?"

"Bill's not here. He's in top hat town."

"Can Mabel visit Bill's house in top hat town?" Bill just groaned negatively. "Ok Bill, I know things may seem...not good, but it isn't your fault. You're constantly summoned by those poop head parents at the Northwest Manor, so I can understand why you would bring that up. You just spiraled out of control." Bill turned away from me.

"I know...I just can't help but feel that I ruined tonight." Reminds me with my nights with Gideon. A date made awkward and weird because of a bunch of other people.

"I know! How about we go somewhere where we can be alone. Like a house!" Bill came out of his hat.

"LIKE MY HOUSE!"

"Yeah....sure. TOMORROW NIGHT! "

"YEAH!"

Bill's P.O.V
-----------------

Mabel walked back in to the party. I got out my bow tie.

"Boys...there might be a few delays in our plan..." Hectorgon was on the line.

"Delays? What do you mean by that?"

"Mabel has proven quite resilient to my tricks. She just doesn't want to make a deal with me." I lied. Really, I'm just caught up with all this dating business.

"Don't worry Boss. We're sure she's going to break somehow." That's up for debate. I hung up. I then teleported to my house.

"Heh. Don't worry, Bill. I'm sure your house is going to be just fine for a date with shooting star." Of course, I was wrong. I opened my door and found that it was....well, a madhouse would be putting it lightly. Eyes were everywhere, the floor had skeletons jumping out, and....oh, yeah, I'm pretty sure chairs aren't suppose to be mercilessly beating each other to a pulp. And that's just 3 out of a billion things wrong with my house.

"Hmm, this might be more complicated than I thought."

Author's notes

Wow. I really made Pacifica's parents true monsters. I know the fandom loves to hate Preston northwest, but don't you think I made him a little too extreme? And on Valentine's Day. Sheesh, I'm messed up.
