A/N: Hey, everyone! Yeah, I know it's been forever since I posted a new chapter, and I'm so, so, SO sorry about that-a couple things came up in my real life that kept me from updating the story. See, my uncle, who has been giving me driving lessons, gave me a challenge lately. He wanted me to write a story for him about Belize (the country where I am right now), so that's been my main writing project, and I have had to put Under Gravity, as well as my original story on hold to do the research and work on that story. I'm not done yet, but I've gotten a lot of work done for it, and it's been so long since I worked on this story, that I figured I'd give you guys the next chapter. And since I always write in advance, I might post the next chapter for you guys in another couple of nights, both as a treat and because around the middle of this week I'm heading out to the jungle with this one group to look at jaguars, and the place we're staying has VERY little internet. Well, enough of that now. On to the story!
Disclaimer: I don't own Gravity Falls, Alex Hirsch does. I don't own Undertale, Toby Fox does. I did, however, come up with the idea to mash them together, so there's that, I suppose?
"Dipper? Dipper?" The now-skeletal Mabel went over to her brother, who was hugging his knees tightly. It was obvious he was crying. Mabel wasn't sure how much time had passed since she and her brother had fallen into the Underground.
A week? Two weeks? A month?
Well, no matter how long it had been, things HADN'T gone well for them. Just a few days after falling down here, almost dying, and ending up as skeletons, they'd been caught by some big scary monsters in armor and taken to the kingdom. And that was when the experiments had started.
Apparently, Dipper and Mabel were the first humans to become monsters. Apparently, they would be valuable to the kingdom. Apparently, the king of the monsters needed their souls…
So now, here the two children were-wearing nothing but surgical gowns and sitting in a cell, confused, scared, not knowing whether they would live or die the next day, or if it was even day or night.
"Dipper, what's wrong?" Mabel looked at her twin in concern. She had a pad over her left eye socket-earlier the scientists had tried zapping her with some kind of ray. It still hurt a little, but they had said that it shouldn't affect her eye permanently. At least, they didn't THINK it should…
"They tried to make me kill something." Dipper whimpered.
"What?!" Mabel gasped.
"There was something there in a cage." The skeleton boy continued, wiping some tears from his eye socket. "The scientists said they wanted to test my powers by getting me to commit a 'level of violence'. I almost did it…but that creature-it just kept screaming and trying to get out-I COULDN'T!"
Mabel threw her arms around him.
"Hey, it's okay, bro-bro." She said gently. "That's good, right? You didn't hurt it."
"But now they're going to hurt us." Dipper sobbed. "Those monsters-they're going to keep doing all these experiments on us. They already hurt your eye." Mabel just hugged him tighter.
"I'll be okay. Dipper, we're going to get out of here somehow, I know it." She finally let him go, and gave her brother a serious look. It was one of the first times he'd actually seen her act like the older twin. "And no matter what happens, we're never going to be like them." She squeezed his shoulder. "Yeah, we're skeletons now, but we're never going to be MONSTERS."
That very same night, the twins were liberated by none other than the Royal Scientist himself. To this day, Mabel didn't know if McGucket was a skeleton like herself and Dipper, or something else completely. She'd wanted to ask him, but there were more important things to worry about-like getting out of those labs safely, and following him into Snowdin.
She remembered how scared she'd been when she saw Stan for the first time. He looked like the king-Ford, Mabel remembered his name was. Neither she nor Dipper had actually met the king personally, but just seeing pictures of him intimidated Mabel. After all, it was because of him that she and Dipper had been getting hurt. Because he wanted their SOULS. But after McGucket explained the kids' story to Stan, a combination of shock, horror, and anger crossed the old goat's face. And after McGucket left, he pulled her and Dipper into the tightest hug Mabel had ever gotten. He assured them that they were going to be okay-that he was going to take care of them, and nothing would ever hurt them again.
The next day, he'd gotten Mabel her hoodie and Dipper his scarf to help keep them warm. It didn't take long for Mabel to realize that Stan was nothing like Ford. He didn't care that Dipper and Mabel had once been human-as he explained, they were kids first. The goat could be kind of gruff, as well as stingy when it came to the money he made from his human museum, but he genuinely did care for the kids. Of course, there were some road bumps along the way-Mabel still missed her parents and wanted to go back home sometimes, but for the most part, the last three years were some of the best times of her life.
She had a nice, happy, comfortable life with Dipper and Grunkle Stan (and later Waddles) in Snowdin, made some great friends, and never saw any of those scientists again. No more painful experiments. And no fights. Neither she nor Dipper would have to kill another creature…
Until now.
"Pacifica! Run!"
That was what Mabel wanted to say. But she couldn't talk-she didn't even have a mouth anymore. She was just another soul wriggling inside the abomination Bill Cipher had become, forced to look through the creature's eye as he tried to destroy the other girl.
"NO!" The word echoed through the void as Mabel saw Pacifica fall to her knees.

Bill's voice came from everywhere-within the void, outside…even from Mabel. He'd absorbed her soul, after all. She was part of him now.
Which meant that she was hurting Pacifica too.
This is a nightmare! Mabel sobbed. The one time I actually try and help-to do SOMETHING, and this happens! I'm sorry, Pacifica! I'm sorry, Dipper!
Without any control over her own soul, no eyes to close, Mabel was forced to watch as Bill summoned a bunch of knives, and sent them at Pacifica…only for them to turn into little pine tree symbols that went harmlessly inside her.
"Wͨͨͥ̄̆͑Ḥ͎̽Ä̍T̹̤ͦͅ?͍̣ͨ̌̍́!̯̩͔̬̼ͬ̓̓̾͋͒̄" Bill's voice echoed in disbelief. Mabel gasped as she saw, to her surprise, that the pine trees were actually healing Pacifica as they went inside her.
Wait a second.
Pine trees?
Dipper?
Mabel!
Mabel wasn't sure if it was a voice or a thought. It came from all around-and yet somehow, she knew exactly where to turn. A figure appeared in the white nothingness-the black outline of her brother. As Mabel watched, Dipper's form became clearer, flickering between his skeleton and human forms.
Dipper! What's going on?! How…?!
I don't know how long I can keep this up! Dipper's mouth moved as his image flickered even more. I was able to break through enough to help Pacifica, but…
You fought Bill's control? Mabel gasped.
Yeah but…aah!
Dipper's image faded from Mabel's view. He was gone as soon as he'd appeared.
Dipper!

"AUGH!" Pacifica screamed out as Bill summoned a bunch of pyramids at her, pointy tip first. Fortunately, it seemed she was healed enough to run.

I have to stop him! I can't let Pacifica get hurt!
Bill snapped his fingers, and a bunch of shurikens appeared, flying through the air to slice Pacifica to ribbons.
NO!
Mabel's scream echoed through the void, loud enough to make an audible sound…and the shurikens turned into shooting stars.
Like the one on Mabel's shirt…
Like the pine trees before, these actually healed Pacifica, even cleaning the dirt and grime off of her.
A strange feeling came over Mabel as this was going on. She let out a gasp, and for just a few seconds, she felt her body reforming around her. She lifted her hands…and like Dipper, she saw her hands going from flesh and blood to bone. She was being torn between her human and skeleton selves.
But it didn't hurt. It just felt like cold water kept washing over her.
What's going on here?
"Dipper. Mabel…"
The names left Pacifica's mouth before she could stop herself. But as soon as she said them, she knew it was true.
They were still in there. And they didn't want to hurt her…they were fighting back against Bill.
"DIPPER! MABEL!" Pacifica pulled herself up…and ran over to Bill.

Pacifica glared at him. Glared.
"Shut up, you freak!" She snapped. Pacifica wasn't sure where to look, so she looked at his middle, where his heart would probably be. "Hey, Boneheads! I know you two can hear me!"
Pacifica?
Dipper looked up-through Bill's eye. There she was.
Pacifica was alone, bruised and bleeding…but she was still there, her overly-mascaraed eyes set in a hard glare.
"You're seriously giving up that easily?!" Pacifica snapped. "I thought you two were supposed to be spooky skeletons! But letting yourselves get eaten by a FLOWER?! Lame!"
Hey, it's not like this was our idea! Dipper snapped back. I've never fought a demon before!
As Dipper spoke, something grew brighter and brighter. It took him a second to realize that the 'something' was him.
Huh? He looked down at his body, his flickering hands.
Dipper! Over here!
Dipper whipped around to see his sister.
Mabel!
"Ư̊͐̓̔ͤͧ̃s̮͇̻͚̝̠̺̒ͫ̽͜e̪̦͜ͅl͉̫͡ͅe̙̙̒̆̈́͐s̷̟̹̱̲̠͔ͦͨs̟̻̬̹͙̏͐̏̀̽͒̄͠!̺̗͎̫͍̪̭̍̈͛̍̎͜" Bill sent a bunch of flames at Pacifica, and Dipper furrowed his brow
I don't think so. Mabel, give me a hand!
Gotcha!
Both twins closed their eyes and concentrated…and the flames turned into bubbles. Only a second after this, however, Dipper felt something tearing through him.
Dipper! Mabel shouted/thought before yelling out. Apparently, she felt the same thing.
It's Bill! Dipper communicated to her. He's absorbing us…I don't know how much longer I can keep this up!
Suddenly, he felt a warm sensation on the place his shoulder would be. Dipper looked up and saw Mabel as he'd never seen her before. She looked solid…but neither human nor skeleton. Somehow, she managed to be somewhere in between.
"I'm sorry, Dipper." She cried. "This whole thing was my fault-I couldn't fight Pacifica, I was the one who got us down here in the first place, got us turned into skeletons…"
No-that wasn't your fault! Dipper communicated. Mabel, you've been doing great. You've pulled me through some really hard times, helped keep me grounded, and you know what? Human, skeleton, I don't care anymore. Not as long as I'm with my sister.
Mabel smiled sadly at him…and then something changed.
Figures appeared around all of them.
Are these…?
The human souls. Mabel automatically knew.
One of the figures reached out its hand to Mabel, and she took it, feeling a warm sensation spreading over her.
They were going to help them. And together, they were all going to defeat Bill, and save Pacifica.
That isosceles monster would never hurt anyone ever again.
You sure about this? Dipper asked.
Yeah. Let's beat Bill!
Dipper took Mabel's hand, feeling the warmth spreading over him as well. He looked forward, seeing Pacifica's face.
She was still glaring at Bill…but she was horrified. Dipper could tell just by looking at her. Her fists were shaking, her eyes were dancing with terror-Pacifica was scared out of her mind.
But she was trying to stay strong, trying to look brave and stand up to Bill. Dipper could almost smell the DETERMINATION radiating off her.
After everything she's seen and been through, she's still not backing down? That's…amazing.
Um, Dipper?
If he had had a corporeal form, Dipper would've turned red. He'd almost forgotten that Mabel was there. Catching himself, he glared ahead as well, feeling power coursing through him-his own, Mabel's, the human souls'.

She jumped out of the way as the souls all left Bill as one, the monster's form crumbling.
The next thing Pacifica knew was whiteness as the universe imploded around her.
A/N: Oh wow-what a ride, huh? Again, I'm sorry if the Zalgo text is hard to read. Now, I'm sure you guys have a few questions. I'll try to answer them all. First of all yes, Old Man McGucket is both the River Man AND Gaster, kind of like how I made Robbie Alphys and Mettaton. This is actually an idea I've had from the beginning though-McGucket, like Gaster, was the royal scientist before Robbie (Alphys), and as such, the one in charge of experimenting on Dipper and Mabel. However, his conscience wouldn't allow him to keep hurting children, monsters or human, so he helped them escape the labs to the safety of Snowdin, then went into hiding, disguising himself and feigning senility to stay under the radar.
Dipper and Mabel were able to fight Bill's influence due to the strength and dual nature of their souls, as well as some help from the human souls. Oh, and BTW, I kinda got the idea for the flashback of the skeletwins in the lab from DeviantArt user Zarla's comic, Handplates. It's pretty interesting, and has been dubbed over by some talented voice actors on YouTube, and I'd advise checking it out. Fair warning though-it gets pretty feelsy...
Well, that's all for now-but this story is far from over. Be nice and review, and I might just get the next chapter up sooner!
