Dipper's POV
>>>>>>>>>>>>>>>

After Bill's Weirdmageddon fiasco, and Mabel and I left Gravity Falls for a couple years, something big happened. And I mean BIG!

~*~*~*~*~*~*~
Flashback
~*~*~*~*~*~*~

I plopped my books on my study desk and set my backpack on the back of my chair. It had been a good year or two since we left Gravity Falls and our teen years were treating us well.

"Dippy! I'm like so sick of schoooooool!" My twin sister, Mabel whined, as she entered out shared bedroom and fell into her bed. Well most of us.

"Come on Mabel, it's only half over." I lightly chuckled at her childish behavior.

"And I'll never survive!" She declared, flopping on her back and laying an arm over her eyes.

"Your over-exaggerating." I told her.

Just then Mabel's laptop began ringing, meaning that someone was face-timing her.

Mabel's glum expression lit up as she clapped her hands in joy, "Dipper! It's Soos and Wendy!" She squealed.

"Well answer them." I told her.

She immediately did and the expanded faces of our friends Soos and Wendy appear.

"Hey!" They greeted.

"Hey guys what's up?!" Mabel asked.

"Nothing much, just me and Melanie been working at the shack and-" Soos was cut off by Wendy elbowing him in the arm.

"Soos! You have to tell them about her." Wendy muttered.

"Her?" Mabel and I asked in usion.

"Aw look what you did now." Soos groaned.

"Guys, what's going on?" I asked.

Wendy sighed, "Well a couple days ago, this little girl that looks like the splitting image of Bill showed up at the shack." She explained.

"And she was just looking around, as if she was looking for something and may I say rather suspiciously." Soos added.

"So what your saying is that Bill was able to clone himself into a little girl to find something in the Mystery Shack?" I asked, trying to piece together what was happening.

"Didn't we defeat Bill by erasing him in Grunkle Stan's mind?" Mabel asked.

"Yeah and we haven't seen any sign of him, so what's the problem?" I questioned.

"She doesn't act like Bill." Soos said.

"She kinda acts like you Dipper." Wendy concluded.

There was a moment of silence in both places.

"What are you guys implying?" I asked.

"Well... we don't really know what to think." Wendy stated.

"Have you talked to her at all?" Mabel asked.

"I have, once I asked her if she lost her mom and she said something like,
'I am your father.' Or wait, was that Darth Vader..." Soos then thought for a moment.

"She told you that she was looking for someone." Wendy groaned.

"YOU AND BILL?!?" Mabel exclaimed.

"I don't remember doing anything like that Mabel!" I defended.

"Well you should come over and check her out." Wendy suggested.

"Yeah, think of it a sneak peak before you guys come back for summer vacation." Soos added.

"Kay, bye!" Mabel waved at them and closed the chat. She then sent me a look.

"What?!" I asked.

"You have some explaining to do." She glared.

"What is there to explain?! It's not humanly possible..." Then it hit me, "Was Bill a girl?!"

"No, I don't see him as a girl. Remember, he created Weirdmageddon, he probably can create a human being. That looks like him. And talks like you. And will call you mom... or dad." Mabel's voice drifted off.

"Your not helping!"

End of Flashback
~*~*~*~*~*~*~

After convincing our parents to let us go back to Gravity Falls for awhile, they almost threw us onto the bus and before we knew it, we have been driving for nearly two hours.

The thought of a little girl looking like Bill and that acted like me popped into my head. I tried to image her, but it was weird either way.

"You okay bro?" Mabel asked and turned to me, clearly sensing that I was deep in thought.

"Yeah." I replied quietly.

"We both know that that is completely bogus." Mabel glared at me.

She was right, I was far from being 'okay'.

"You got me." I sighed, glancing out the window.

"Don't worry about it bro, I totally understand. I mean, I don't know how I'd react to having a secret kid that came out of nowhere and belonged to my enemy." Mabel explained, "I'm sure that you are really confused and can't really decide what to do." She concluded.

Wow, she was bang on! Did I ever mention how great an observer and listener Mabel was? No?

Anyways, she was completely right about my whole situation. I mean I haven't even met the girl, and I'm debating on what to do.

***************
Time-Skip
***************

Soon the bus stopped in front of the Mystery Shack, back in Gravity Falls.
Mabel and I hopped off the bus, with our luggage and took in the scenery that we so longed missed.

It looked like nothing really changed, which put me to ease.

Now Mabel on the other hand was practically jumping off the walls, meaning she was excited.

The bus then drove off and the two of us decided to go inside the shack and see what had all changed.

When we entered, it seemed that hardly anything had changed, same old shack, just with cheaper merchandise.

"Oh hey you two!" A lady behind the counter greeted.

"Melanie?" We asked in usion, looking at the familiar woman.

She giggled, "Yep, it's great to see you guys." Melanie hadn't changed that much, still had her chubby cheek and dark blonde hair pulls back into a ponytail. She wore an employee apron and hat, Soos must of made a change.

"DUDES!" The familiar voice called.

"Soos?!" Mabel and I turned to Soos and gave him a hug.

"We've missed you sooooo much!" Mabel cried.

We all pulled away from the hug. Soos adjusted Grunkle Stan's old hat on his head, and dusted off his suit.

"Yeah man, how's it been going?" I asked.

"It's been great dudes! Everyone in Gravity Falls loves the shack and we're making good money." Soos explained, "Hold on something's different about you two." He gave a concentrated stare.

"Dipper having a baby beard?" Mabel asked.

"It's not called a 'baby beard'!" I growled at her.

"No, but have you dudes got.... taller?" Soos asked.

I face palmed myself.

"So Soos, where's Wendy?" Mabel asked.

"Oh she's just hanging out with her friends." Soos replied, "I told her that you guys were coming, so she'll be here soon... probably."

"Oh." I was really excited to see Wendy again.

Then suddenly, the door opened. Out came a girl about five years old, with short brown spikey hair, fair tanned skin, with one eye hazel brown and the other bright blue. She wore a pyramid styled vest and skirt with a white blouse underneath and a black ribbon tied overtop.

"Is that her?" Mabel asked in a whisper.

"Yeah, what did I tell you?" Soos responded.

The girl then walked over to the little hat shelf, that held hats that resembled the one I got when Grunkle Stan ran the shack.

I could feel my stomach fill with different emotions, anxiety, confusion and worry.

(You all thought it was gonna be inappropriate didn't you?)

Then, my legs took control and casually walked towards the girl. She noticed my presence and looked at me, her eyes glimmered with curiosity.

"Uh, hi! I, uh couldn't help but notice you taking a interest in those hats." I nervously stated, trying to pick up a conversation.

"Uh yeah, they look kinda cool." She stammered in reply.

She was kinda cute to be honest, I mean for a dream demon's child.

"Yeah, I used to have one like them, but I gave to a friend of mine." I told her.

"That's cool." She mumbled, awkwardly.

"Hey I have an idea, how about I get us both a hat? Then we can wear the coolest hats Gravity Falls has ever seen?" I suggested.

She smiled, "Are you sure Mister?" She asked.

"Yeah definitely." I replied, "And by the way, you can call me Dipper." I introduced.

She stared at me in awe, "As in Dipper Pines?" She asked.

"Uh yeah, how did you know?" I asked.

"Dad talks about you every once in awhile." She responded and picked up two of the hats on the shelf, handing one to me.

I didn't reply and paid Melanie for the hats.

"So, you uh visit the shack often?" I asked, trying to start up some more small talk.

She shrugged, "Sometimes, whenever Dad needs his rest." She replied quietly.

"So, weird question, but who is your dad?" I asked awkwardly.

She stayed quiet, then motioned for me to get to her level.

((I totally thought like: 'get on my level bitch!'))

I kneeled down to her and she cupped her hand around my ear and whispered, "C'mon Pinetree, I think that you know pretty damn well who he is."

I backed away and looked at her with shock. She grinned at me, "Come on, you know you wanna see him."

I glanced at Mabel and Soos, who were busy chatting about something. I turned back to the little girl, who was waiting for my answer.

I sighed, "Alright, lead the way." I responded and got up to my feet.

She then led me into the forest and we walked for a few minutes. I was beginning to wonder if she knew where she was going.

Before I could ask, suddenly a big old looking, stone statue of Bill stood halfway in the ground. Beside it was a summoning circle.

The girl turned to me and a smiled, "You want to see him?" She asked.

"Uh- you know how to?!" I asked astonished that this little girl knew how to summon a dream demon.

"I do it all the time." She replied,
sitting in the middle of the circle, legs criss-crossed.

After chanting a spell, a burst of blue energy emitted from the girl's eyes, and everything became grey, except me and the girl. Suddenly, a triangle appeared and what looked like a human version of Bill appeared, his legs crossed.

He stretched his arms and let out a loud yawn. "Morning already? Jeez this dimension and it's time lapses." He muttered and spotted the girl. "Mystery! Back so soon? Nice hat by the way, makes my little girl look cuter." He smiled at the girl, who's name was now Mystery.

"I brought a friend Daddy." She smiled.

"A friend?!" Bill asked excitedly, but spotted me, "Pinetree? Is that youuuu?" He sung, levitating his way toward me.

"Bill? You have a human form?" I asked.

"Why yes I do~ Don't know why I didn't use it before." He shrugged.

"You have some talking to do." I said sternly.

"Talking? I've done plenty of that already." He said, smirking.

"You know what I mean." I grumbled.

"I do~"

Mystery stood up and tugged on her dad's tailcoat. "Daddy, what's Pinetree talking about?" She asked.

Bill sighed and sat criss-cross in the air, "I suppose I better tell you about Mystery."

"That would be nice." I responded.

"Well to start, when you guys destroyed my creation of weirdmageddon, my soul was transferred into some white and plain void. I gotta tell you, it was lonely in there, so I created Mystery here, since I guess we had the strongest connection, she acted more like you, well because I missed your smart remarks." He explained, "Somehow she was able to transport into your dimension, will my share of powers. From there, we could communicate from my summoning circle, while she found a way to get me out of this damn-"

Mystery cut him off, "Swear." She glared.

"Sorry, I meant dang, this dang void." Bill corrected himself.

I didn't expect Bill to be such a good dad, I must say that I was impressed.

"I didn't expect you to show up though Pinetree." Bill chuckled, "You must really like me." He said, in a joking matter.

I blushed in embarrassment, he then looked at me shocked.

"Oh my god you do..." He said astonished then turned to Mystery and giggled like a school girl with Mystery, "He really does like me."

'Oh god...'

•••••••••••••••••••••••

"And that's how Pinetree and I got together." Bill chuckled, his arm around my shoulder. Mystery reading a book between us.

"That's adorable!" Gideon's demonic guardian clapped in her British accent.

"I don't approve!!" Mabel's cried.

Mabel giggled at his reaction.
