A/N: Wow, I do believe this is my longest chapter yet. And like the last couple chapters, I'm going to switch POVs every now and then-giving the spotlight to a CERTAIN pair of skeleton twins for a while...

Pierce-Heh, truth be told I've never actually played Undertale either (mostly because I don't want to download the game on my old crappy laptop), though I've watched Jacksepticeye's Let's Plays of the game. Not to mention having a fair bit of fanart on my computer-though still not as much as FNAF, heh...anyway, I'm glad I've got you interested, even though you're not too big a fan of either Undertale or Gravity Falls. Gives my ego a boost ^^

XXPay4XtraShippingsXX-Give yourself some credit; some of my best ideas have come from reviewers (particularly since I have a bad habit of going into new stories half with ideas, half making stuff up as I go along). Yeah-it would be unrealistic to have Pacifica just immediately go from Alpha Bitch to Purity Sue like that, so I wanted to have her slowly grow and develop as a character as she goes along on her journey. Glad to see that it's working.

Disclaimer: If I owned Gravity Falls or Undertale, I wouldn't have to worry about paying off my student loans. I'd be set for life.

"Alright, here's your phone." Robbie said, handing the phone to Pacifica. "Don't say I never did you any favors." Pacifica took the phone and went to the contact list, looking through all the numbers.

She didn't recognize a lot of the names…except one.

"Hello, Wendy?" Pacifica said as she dialed Wendy's number.

"What are you doing?!" Robbie demanded, looking panicked. Pacifica ignored him as she listened to Wendy say

"Pacifica? What happened? How did you get my number?"

"I ran into this robot guy, Robbie, and had him make me a cell phone." Pacifica answered.

"Robbie?!"

"Yeah. He said he'd help me get to King Ford." Robbie looked very nervous.

He had it bad for Wendy, alright.

"…is he making you say this?"

"Huh?" Pacifica blinked in surprise, then shook her head (despite being on the phone). "No, he's really helping me!"

"Uh-huh…" Wendy sounded utterly unconvinced. "Well anyway, I'm glad that you have something now, cause I have to go. Duty calls."

Pacifica felt like a balloon had been deflated inside of her.

She'd been looking forward to having a body guard to protect her until she got to meet the king, and maybe make things easier by talking to him beforehand, but it looked like that was out of the question.

Just her and a moody teenage robot being snarky over the phone as she headed off into more danger, faced more monsters.

"Great…"

"Don't worry, though." Wendy said. "I'll text you Dipper, Mabel's, and Stan's numbers in case you need any more help, or even just need someone to talk to."

"But…!"

"Take care of yourself, Blondie." Wendy finished. "Oh and, keep Robbie in check, okay?"

With that, she hung up.

Robbie groaned, holding his head in his hands.

"She thinks I'm a total jerk."

"I can't imagine why." Pacifica said sarcastically, raising an eyebrow. At that moment, a couple beeps came up on her phone. Pacifica looked down, seeing some phone numbers in her text messages. The first was Dipper's number, then Mabel's…then Stan's.

Pacifica felt her heart sink. She'd never admit it out loud…but she actually missed the old goat.

I just hope he's…okay.

She took a breath, looking over at Robbie.

"So um, thanks for the phone."

"Yeah, whatever." He shoved his hands into the pockets of his lab coat, looking off to the side. Pacifica's eyes fell to the broken heart symbol on his chassis. Maybe it was symbolic?

Without another word, she turned and left.

"…up. Wake up. Wake UP. Please…"

Mabel slowly opened her eyes, her vision fuzzy. However, she could make out the outline of a familiar person in front of her.

"Dipper?" She blinked a couple times to clear her vision…and screamed as she saw her brother.

"Mabel, Mabel, it's okay!" The skeleton had the same clothes and hair as her brother. It even sounded like him. It was just...so wrong.

Mabel backed away from the thing, her eyes wide with terror.

"YOU'RE A SKELETON!" She raised her hands to her face…only to see nothing but bone. "AUGH!" A horrible thought came to her. Mabel lifted her bony hands to her face, feeling bone there as well.

"I'm a skeleton!"

"Mabel, calm down!" Dipper walked over to his twin sister, putting a hand on her shoulder. "Everything's…"

"WHAT HAPPENED TO US?!" Mabel looked at Dipper in shock and fear. "Are we dead? Are we going to stay like this forever?!"

"I don't know!" Dipper shot back before letting out a sigh. "All I remember is laying in the snow, cold and hurting everywhere. The next thing I knew, I woke up like this." He motioned down to his skeletal body, and tears filled Mabel's eyes (or was it eye sockets?)

"I don't want to be dead! I didn't even get a chance to get a boyfriend yet!" She started crying, lifting her bony hands to her face. "I'm just a kid!" Dipper put his hand on her shoulder.

"I'm scared too, Mabel!" He admitted. "But hey…it could be worse."

"HOW?!" Mabel asked. "Look at us! We can't go home like this! Mom and Dad would freak!"

"Well, at least we're together." Dipper gave her a sad smile (or at least Mabel thought he did, it was hard to tell since he was a skeleton now). "Look, I don't know what's going to happen now, but we're going to figure this thing out together, okay? We'll find some way to get through this-just like we've gotten through everything else." Mabel looked at him, and Dipper held his arms out, the smile still on his skull.

"Awkward sibling hug?" Mabel sniffed, wiping a tear from her eye socket.

"Awkward sibling hug." The two now-skeletal twins put their arms around one another in their trademark affectionate gesture, then patted each other's backs.

"Pat, pat!"

Mabel stood at the door to the ruins, a sigh escaping her nonexistent lungs.

"Has it really been three years?" She asked no one in particular, a nervous smile on her skull. "Sheesh."

Looking back on it now, that moment after they woke up in the underground, after seeing that they'd become skeletons, really embarrassed Mabel.

She and Dipper were twins. And on top of that, she was the older one. Yet he'd had to take care of both of them. Even now Dipper was acting like the protector, what with trying to join the Royal Guard. The twins hadn't grown much since then, but Dipper was willing to go and fight, to put his life on the line, just so he could get closer to the king, to be his apprentice. So he could get his journal, and hopefully find a way to make them human again. Honestly, Mabel didn't see why he was going through all that trouble-Ford was Grunkle Stan's brother, after all. So in a way, he was as much a Grunkle to them as Stan. Surely Dipper could just ask him for it? Or Stan could?

As soon as she thought it, Mabel realized how stupid the idea was. Honestly, just asking the king for his big dumb book of human secrets? And anyway, Stan and Ford…weren't getting along so good. Mabel remembered Stan telling them that after they'd started living with him. That thought kind of scared her.

But of course, Dipper had stepped up to be the brave one and do what he had to to get them out of there. To get their humanity back.

Mabel sighed, shaking her head.

"Stupid."

Even as she said it, she didn't know if she was talking about Dipper or herself. She then looked up, a hard look on her skull.

The image of a heart appeared on her shirt as she turned and walked away.

Back in Hotland, Pacifica had managed to walk right into another fight.

"Human! Stop!"

"Huh?" Pacifica turned around, and gasped as she saw what looked like a huge bear with many heads. "AUGH! What are you?!"

"They call me…the multi-bear." The monster answered. "And I can't let you pass-not unless you defeat me."

"But I don't want to fight!" Pacifica said as the bear swiped at her. She started thinking of different tactics. In a panic, she started singing a song she heard once.

"Um, uh…Disco Girl! Coming through!" The multi-bear stopped attacking immediately.

"Wait. You like Icelandic pop group Babba?"

"Uh yeah, sure." Pacifica felt it would be easier to just agree with the creature.

"I can't hurt a fellow Babba fan." The multi-bear stepped back, and Pacifica let out a sigh.

"I'm going to spare you, okay? Now let me go!"

"Fair enough." The multi-bear stepped aside to allow her to pass, and Pacifica stepped onto the conveyor belt.

"Well, that was easy."

No sooner had she gotten off the conveyor belt than Pacifica reached a whole LABYRINTH of other conveyor belts.

"Oh, you've GOT to be kidding me." Pacifica sighed, rolling her eyes. "Alright, fine. Let me see if I can figure this out…" She rode one conveyor belt, then got onto another, then another, riding around and around until finally getting off…at a series of lasers.

"UGH! I swear, if that robot doesn't…"

No sooner had Pacifica said this than her phone rang. She fished it out of her pocket and held it up to her ear.

"Hello?"

"Hey so um, I've been watching you or whatever." Robbie's unenthusiastic voice droned on the other line. "Guess I should tell you about the lasers."

"Yeah, that would be nice!" Pacifica snapped.

"Right, so the blue lasers won't hurt you if you don't move." Robbie started. "Orange ones, on the other hand-you can just walk right through them. Got it?"

"No, I…!"

"Kay, later." Robbie hung up, and Pacifica narrowed her eyes.

I hope he rusts.

She looked back out at the lasers, taking a breath.

"Alright, here goes…" She saw one of the orange lasers moving towards her, and just casually walked through it. She then stopped at a blue laser. "How do I get through this one?!" She looked down. The laser wasn't high enough that she could just walk under it, unless…

Pacifica bent back; making sure no part of her body was touching the laser. It took some doing, but she made it past.

"Okay, that's over." She kept walking until she reached the opening to a tower…and saw another laser.

Ring ring! Ring ring!

Pacifica answered the phone, and Robbie's voice greeted her again.

"Now, that blue laser you can't pass." He said. "Gimme a moment, let me hack it…" He hung up, and about twenty seconds later, the laser snapped off.

"Well, that's a relief." Pacifica kept walking, and looked down at her phone, scrolling through the names.

Stan's was the first that caught her name.

Maybe…maybe I should check up on him. Just like-to make sure he hasn't eaten any soda cans or anything.

She dialed Stan's number and held the phone to her ear. The phone rang once. Twice. Three times.

Finally, the call just dropped.

Pacifica wasn't sure why, but she felt her heart sink at that.

She shook her head, clearing her thoughts.

"Dipper…" She read his name on the phone-then froze in place.

The memories of their fight, the talk afterwards, Dipper trying to protect her from Wendy, all came back before Pacifica could stop herself.

"Hmm…" Biting her lip, she dialed Dipper's number, putting the phone to her ear.

"Hello?" Dipper's voice came over the phone. He sounded confused, but for some reason Pacifica felt her heart skip a beat as she heard him.

"Dipper!"

"Pacifica?" He asked. "What's going on? How'd you get my number?"

"Well, this robot guy, Robbie, made me a phone and…"

"Robbie?!" Dipper sounded mad. "Ugh, that guy's the worst! He thinks that just because he's the Royal Scientist he's better than everyone, and he doesn't even do his job well! He just…!"

"Jealous much?" Pacifica smirked. She could practically see Dipper blushing over the phone.

"Maybe a little…" He mumbled.

"Because he likes Wendy too?" The blonde guessed.

Dipper didn't answer, and Pacifica let out a sigh.

"Well, I just wanted to tell you where I was." Pacifica said, looking off to the side. "You know, so you'd know I was okay."

"Yeah, yeah…that's good." Dipper said. "Sounds like you're getting closer."

"Yeah." Pacifica nodded.

"Well uh-I should get back to doing my patrol duty, you know?"

"Yeah, you do that." Pacifica nodded. "Don't let me stop you." Just as she was about to hang up, Dipper said

"Hey, Pacifica?"

"What?" Pacifica asked.

"If and when you meet King Ford-just go easy on him, okay? He's my great-uncle too."

Oh right-he's Stan's brother. I forgot about that…

"I'm not going to fight him!" Pacifica told the skeleton boy. "I don't do that, remember?!"

"Well in that case-be careful." And with those words, Dipper hung up.

Once he'd hung up, Dipper resumed patrolling Snowdin.

Can Pacifica really do it? I mean, she's gotten this far, so…

His thoughts were suddenly interrupted by something.

"Who's there?!" Dipper whipped around and saw…nothing. He narrowed his eye sockets at the spot.

"Weird. I could've sworn I heard something…" He turned back around-and his eyes widened at what he saw. Or, rather, WHO.

"You?!"

That was the only word Dipper got to say before he was attacked, his pained scream echoing throughout the forest.

A/N: Oh no! Dipper down! What to do?! Wait, what am I saying? I already know what's going to happen! TBH, I'm pretty happy with this chapter. Yeah, I figured I'd give the skeletwins some more screentime. I feel kinda bad about mostly neglecting them, since Sans and Papyrus are pretty major characters in Undertale, and Dipper and Mabel are, well, the MAIN PROTAGONISTS of Gravity Falls. I particularly wanted to show a little more of their backstory, and give some insight into Mabel's situation. That's one reason why I wanted to make Mabel Sans instead of Papyrus-both characters have a lot of hidden depth to them. Sans uses bad puns and laziness to hide the fact that he's actually a very unhappy character, and Mabel acts like a smiley, flirty girl, but she's actually really scared of growing up. Plus, both Sans and Mabel care a lot about their brothers. So it goes without saying that whoever hurt Dipper is in for a bad time...

Also, I figured I'd put in just a hint of Dippifica for the shippers...hope you guys liked.

So, how's about doing me a favor and reviewing?
