A/N: So, I have a bit of a dilemma right now. You guys might have noticed, I've been trying to post links to my Tumblr art on my profile, but nothing's coming up :/ Any advice?

XXPay4XtraShippingsXX-Yeah, Dipper and Mabel didn't have as easy a time as Pacifica. Thank goodness for the goat grunkles!

Well, on to the chapter.

Disclaimer: I own neither Gravity Falls or Undertale, and unless I get a TARDIS, go back to the past, and create them before Alex Hirsch or Toby Fox, I never will.

Pacifica took a breath to steady herself as she faced Dipper.

Relax. He's a bag of bones; he can't be that hard to…

Pacifica's thoughts were interrupted as the skeleton boy grabbed a large bone out of seemingly nowhere, throwing it at her.

"AUGH!" Pacifica tried to run off, but ended up getting knocked backwards into the snow.

"You didn't think I'd make this easy, did you?" Dipper asked. "I've come this far, I can't let anything get in my way! Especially not some fake blonde who got lucky!"

"I'm NOT a fake blonde!" Pacifica said with a glare as she pulled herself up. Dipper threw another bone at her, but Pacifica avoided this one, moving to attack him.

But as she reached him…she didn't see a skeleton. She saw a little boy, broken, bleeding, and dying. Pacifica froze in her tracks…and that was all the chance Dipper needed to attack her again.

MOVE!

Pacifica's body moved on its own, allowing her to avoid being hit by a bone. Dipper scowled at her.

"What are you doing?! I thought you were going to fight!"

"I am!" Pacifica shot back. Dipper prepared to throw another bone attack, but Pacifica was faster. She got a sudden adrenaline rush and shot forward, using her stick to knock the bone out of his hands.

Go again! Get him!

Huh? Pacifica blinked in surprise. Those AREN'T my thoughts!

As she was distracted, Dipper shot up again, grabbing another bone, which Pacifica blocked with her stick.

"You're unpredictable, which makes you dangerous." Dipper sneered. "If and when I bring you in, King Ford will DEFINITELY make me his apprentice!"

"Wow, obsessed much?" Pacifica said. "Why is this so important to you anyway?! You're a kid!"

"I'm not telling you ANYTHING!" Dipper threw another bone at Pacifica, and she just knocked it away with her stick. Before Dipper could move, Pacifica knocked him down.

"AUGH!"

"I spare you." Pacifica said, announcing that the fight was over.

"Wait, what?!" Dipper looked up at her. "Just like that?!"

"That was the deal." Pacifica said. "Fight's over, and I'm sparing you, okay?!"

"No, this isn't over yet!" Dipper pulled himself up, pulling out another bone. "I can still fight! I can beat you!" He threw bone after bone at Pacifica, and she avoided all but one, which caught her in the stomach. Pacifica gasped, feeling the breath leave her. "I can't give up! Not when I've come this far!" Pacifica looked up…and gasped when she saw him.

There, on the front of his armor, was the image of a heart, like the one that had appeared on Pacifica's sweater when she'd met Bill for the first time. His soul.

A human soul…

"Stan took you and Mabel in to protect you." Pacifica said, the words leaving her mouth before she could stop herself. "From monsters who might try to kill you to get your DETERMINATION."

"Leave my family out of this!" Dipper yelled. He threw another bone attack at Pacifica, but it was obvious his heart wasn't in it. It just veered off to the side, falling into the snow behind her. Pacifica sighed, standing up.

"I spare you." She said again, simply. Dipper reached for another bone, but he seemed done. He fell to his knees, lowering his skull sadly. Raising an eyebrow, Pacifica walked over to him, and the skeleton boy sighed.

"Some aspiring Royal Guard member I am." He sighed miserably. "I'm no fighter. I was brought down just by a few words."

Pacifica was quiet. How HAD she known what to say? Was it Gideon, invading her thoughts and influencing her? She wasn't sure she liked that thought-especially since he'd been egging her on to fight.

A cold wind suddenly blew, and Pacifica shivered.

"Um, hey, I know you're having a moment here and everything," She started, "But I don't want to just stand out here in the cold so…"

Dipper stood up suddenly.

"Come with me."

Pacifica didn't know what she was expecting as she let the skeleton lead her through the woods. But she noticed that somehow, it got less cold as they passed through the trees. Finally, she noticed a small wooden shack in the clearing.

"What's that?" She asked.

"That's where Mabel and I used to live three years ago." Dipper answered, his back to her. "After we fell down here. After we lost our humanity." He let out a shaky breath. "I'd never been in worse pain. But I wasn't ready to die-especially not when Mabel still needed me." He turned to look at Pacifica seriously. " I just remember waking up one day like this." He shook his head, smiling a little. "I'm not gonna lie, I freaked out. Me and Mabel were both really scared, but we had to stick together and be strong for each other. After a couple days we found Stan, and he took us in, treated us like we were his own grandkids. Well, Mabel asked if we could call him 'Grandpa'." Dipper actually smiled a little at the memory, shaking his head. "But Stan insisted on just being a great-uncle. He's not the best, but he takes good care of us."

"But…what about your parents?" Pacifica asked before she could stop herself. "I mean, you guys are just kids, after all. You had to have had a mom and a dad." Dipper's smile faded as he let out a sigh.

"Well yeah, but what can we do? We're stuck down here. Me and Mabel can't get back to the surface." He looked at Pacifica sadly. "Maybe it's for the best. I mean, I really miss my mom and dad, but they'd freak if they saw us." As Pacifica watched, Dipper pulled off one of his gloves, revealing a bony hand, like Mabel's.

"Can't say I'd blame them. I'm a monster now, after all."

Pacifica felt herself overcome with a strange emotion that she'd never felt before in her twelve years of life. She was actually sorry for someone else. The concept was so foreign to her, so alien, that Pacifica almost didn't recognize it. But listening to Dipper's story…all of a sudden, she realized why he'd been so determined to catch a human. Why he wanted to become the king's apprentice.

"You think he might have a way to make you and Mabel human again…" Dipper didn't answer, and that was fine with Pacifica. She was talking more to herself than to him.

This whole thing was so…unreal. Those two kids, who couldn't be older than her, had fallen into the underground, basically died, and now were skeletons living in a weird place full of monsters, like her. The difference being that THEY couldn't go back. Or didn't feel like they could.

"Forget it." Dipper finally spoke as he shook his head and stood up. "If you want to get through the portal, head straight to the Capital. You'll have to go to King Ford. He might let you through if you ask. Also, you'll probably run into Wendy." The skeleton boy shrugged. "She's the head of the Royal Guard, so she'll probably try and fight you too. But I can try talking to her-maybe I can get her to leave you alone." Dipper sighed heavily, then gave her a sad look.

"I hope you can make it back home…Pacifica. At least one of us can go back." Pacifica looked down at the ground. She didn't know what to say. Dipper was the complete opposite of his sister, she realized. Mabel always seemed so happy when she met her, always ready with the terrible puns. Was she really like Dipper-trying to hide how much she was hurting? Pacifica knew that feeling only too well…

"Thanks." She started to turn, then stopped, looking at Dipper. "And for what it's worth-I don't think you're a monster." He gave her a surprised look, but Pacifica didn't respond as she walked off. She meant it.

What's going on with me? She wondered. For once, she knew what it was like to feel sorry for someone other than herself. She couldn't imagine what it was like being in Dipper's or Mabel's shoes.

Pacifica clutched her stick tighter, some small part of her brain amazed at how much she was learning down here in the Underground.

A/N: Well, I hope you guys liked it. Obviously, I had to do the fight different than Frisk and Papyrus' fight in Undertale, especially since Pacifica obviously wouldn't flirt Dipper into a date XD So I decided to have him show her his and Mabel's old home instead. I also wanted to keep their personalities as close to GF as possible, what do you guys think? Did I do a good job?

Also, yes-Gideon's trying to influence Pacifica. At least he didn't get through to her this time. Dipper lives to fight another day! But will Pacifica be able to fight Gideon off forever? Will she end up killing someone after all? And will she survive when a CERTAIN new foe shows up to fight her? Stay tuned to find out, and as always, review!
