Summary: So we have one questionable "we're just friends" relationship, two in denial teenagers with bottled up feelings for each other, and spending three months of summer in Gravity Falls after four years of not seeing each other. Huh. Aren't we in for a treat?

Author's notes: I just finished watching the show a few days ago and I've been itching to write a DipperxPacifica fic so here it is! Rated T for language. Also, the characters might seem OOC but do keep in mind that the setting of this fic is five years after Weirdmageddon. It would be, well, weird if they still acted like their twelve-year-old selves.

Happy reading!

Chapter 1
Dipper Pines

I have always been fascinated with numbers. Whether it be telling the time, measuring the distance from point A to point B, or solving a Math problem. There's something calming and assuring about certainty and numbers gave me that. So what I don't understand, as I checked the car's GPS, is why the hell am I anything but calm?

Destination: Mystery Shack, Gravity Falls, Oregon
ETA: 21 minutes

I released a sigh as I loosened my grip on the steering wheel.

Calm down, Pines. You've been going to Gravity Falls for the past five years and you've always been excited. BE. EXCITED.

I gulped. Okay, that didn't help.

21 minutes. 1,260 seconds.

Something caught my eye and I checked my rear view mirror to find that the car behind me kept on flashing its headlights. Less than three seconds later, my phone was ringing.

I rolled my eyes before answering. "What is it now, Mabel?"

"I should be asking you that,"I heard her voice say through the car's speakers. We both decided set up our phones to our cars' stereos before we left California since it was more convenient than pressing your phone against your ear while driving. "Mind telling me why you're driving slower than usual?"

"I don't drive slow."

"Yeah, you do. I knew I should've been the one to lead this stupid convoy."

"Mom and dad specifically asked me to drive first since you might, I don't know, get yourself killed because you drive like a maniac," I explained.

She laughed. "At least I don't drive like an old woman."

"Hey!" I ended up smiling.

"Seriously though, are you okay?"

"Why would you think otherwise?" I asked curiously. "Oh shit, you think we're finally getting that twin telepathy thing?"

"Seventeen years too late, don't you think?" There was a pause. "Waddles says you're crazy and that you're avoiding my question." How she managed to drive with her pet pig for hours, I have no idea.

"You're the crazy one," I answered and mentally debated whether or not I should tell her.

Mabel must have grown impatient due to the long silence, that or we finally flipped the switch to our twin telepathy shazam because she said, "Spit it out already."

"Fine," I conceded. "I just feel like something's going to happen. A sixth sense maybe."

"Whoa." After our first summer in Gravity Falls, we've learned to always trust each other even if it's just a quote feeling unquote. "A good thing or a bad thing?" She added.

"I don't know. A little bit of both?" I answered as we passed the Welcome to Gravity Falls sign. "Or it might just be my lack of sleep." Nothing out of the ordinary has happened since the Weirdmageddon in Gravity Falls. By out of the ordinary I mean, end of the world-ish vibes, unless you count global warming. The small town still had its fair share of supernatural occurrences but not as extreme as before.

There was silence on the other end of the line. I raised an eyebrow and checked my rear view mirror to check if Mabel's car was still following me. "Mabel? Still there?"

"Oh!" Then followed by fits of laughter I've gone accustomed to. "Sorry. I was nodding my head," she said in between her laughs. "If something is up, Grunkle Stan and Grunkle Ford would have told us already don't you think?"

"Yeah, I guess so."

"Either way, we'll find out when we get there. Shrug it off for now, little brother."

I groaned. "Five minutes, Mabel. You're older by just five minutes."

"A lot can happen in that span of time, baby bro. Don't belittle those five minutes."

I grinned. Well this is rare. "Words of wisdom by Mabel Pines, everybody."

"Thank you, thank you."

The call ended a minute later and once again I checked the GPS, which was pointless since I already knew the way.

Calm the fuck down, Pines.

I was getting the bags from Mabel's trunk when a voice said, "See? Nothing out of the ordinary." She took a deep breath. "Nothing like the smell of unicorn poop among others. Yep, we're in Gravity Falls alright."

I turned to look at my sister who was facing the Mystery Shack. Her hair was up in a messy bun and she finally realized how hot the summer heat was because the finally stopped wearing those sweaters of hers but instead she wore a gray shirt with the words "Hogwarts Alumni" printed on it and a pair of jeans. Since the voyage of our great uncles on the Atlantic Ocean ended two years ago, Soos gladly gave the management back to Grunkle Stan. Soos said that he had enough experience to start up his own little business in town. Nonetheless, Grunkle Stan and Grunkle Ford's absence in Gravity Falls didn't stop Mabel and me from spending our summer vacations here. It became some sort of a tradition for us. Soos was kind enough let us stay at our usual room up in the attic during that time.

I nodded at her direction before I stared back at the bags that she brought. "Damn, woman. How many years are you planning on staying here?"

Mabel looked at me as if I spoke another language. "It's just three duffel bags and a backpack."

"I only brought one duffel."

Mabel rolled her eyes and waved me off. "You go on ahead. I gotta go call Grenda and Candy. We're headed to the pool later," she said and gave out a little squeal. "Plus I think Waddles must have wandered off again."

"You just want me to bring all of your things to the Shack."

She gave me a sheepish look. "Perks of having a servant! Oh. Brother. I meant brother."

"Ha," I gave out single laugh. "Such a comedian."

I don't know what came over me but I decided to carry all of our bags so that I'd only make one trip. Four duffel bags, one backpack.

"Smart decision, Dipper," I said to myself as I huffed at the steps that lead to the front porch. Beads of sweat were alread rolling down on the sides of my face. My arms were starting to ache while my legs were already shaking. I need to start working out again. What the hell did Mabel pack, anyway? Her bags weighed a ton. I felt like the Titan god Atlas from Greek mythology.

Gurnkle Stan and Grunkle Ford were out of town until next week for God knows what and they forgot to leave a spare key for the house but they told us that the Shack was open, it had a new staff and all that since Wendy was in college and Soos has his own store, so that we should just let ourselves in through the gift shop's entrance.

I managed to reach out a hand towards the doorknob but the door was pulled open by someone from the inside startling me. And just like that all the bags I was carrying were on the floor. Damn it.

I caught a glimpse of a girl with light brown hair who opened the door from the inside before I crouched down and turned my attention to the bags once again. She must be the part of the new staff great uncle Stan was talking about.

I saw the girl's hand reaching for the backpack and the girl said, "Uhm… let me help you with that."

"It's alright. You don't have to-" I looked up and suddenly I forgot what I was supposed to say.

I blinked twice (maybe thrice?) to confirm that I wasn't seeing things. Her hair might be different but I'd recognize those dark blue eyes anywhere. I've spent most of my time looking at those eyes the following summer after the Weirdmageddon.

She didn't look surprised to see me. She actually looked like she was in a hurry to leave. But I knew she recognized me. We ended up staring at each other for I don't how long but she was the first to look away.

"I was just closing up. Stan told me you were coming. I planned on leaving the key under the mat," she mumbled as she played with the ends of her hair. Her brown hair. Why isn't she blonde? Has this got something to do with what I told her before?

No. Get your head out of your ass, Dipper. She did not go back to her natural hair color just because you said four freaking years ago that it suited her better.

I cleared my throat, not sure what to say.

"Pacifica," I managed to blurt out. Her name sounded foreign to me even though I thought of her countless of times before. "I didn't know you were back."

It was only then that I realized that this was the first time we saw each other after four years. I straightened, bags completely forgotten and tried to comprehend what was going on. I stared at the girl in front of me, the girl whom I haven't seen in so long, who suddenly left during our second summer in Gravity Falls without even telling anybody.

The very same girl who happened to be my first kiss.
