A/N: Yeah...the job ended up not happening. My cousin advised against a marketing job, so I guess I'm just going to keep looking. Though I have started going out to the public library this week, so here's hoping I find something soon. And I'm sorry this chapter took so long-but with Undertale's one-year anniversary, I knew I couldn't hold it off for much longer. So here you guys go!

XXPay4XtraShippingsXX-Yep, that's the plan XD Well, you'll find out soon ;)

Dossypet-Glad you like it. Here's the next chapter!

It seemed like hours as Pacifica followed Stan through the ruins, walking up stairs and passing old, weathered walls.

Was this actually real? As much as the little blonde's mind said it was, another part of her brain said that this was a crazy dream. The stories were true. Monsters were real. And now she was following one through the old, broken-down buildings. Yes, Stan had saved her from Bill just now…but what if the whole thing was a set-up? What if he was luring her to his home so he could eat her?

Pacifica was sure she tasted delicious-she was a member of the most prestigious family in Gravity Falls, after all.

"Well, here we are." Stan said suddenly, stopping.

"Where's 'here'?" Pacifica asked.

"Your new home." The goat man answered, indicating to a door.

"WHAT?!" Pacifica exclaimed, a little louder than she intended.

"Lemme show you how to get in." Stan walked on some tiles and flicked a switch, causing the door to open. He then walked back over to her. "These here ruins have lots of puzzles. Fusions between diversions and keys." He waved his hand nonchalantly. "You gotta solve them to get to different rooms. It's a headache, but that's just how things work down here. Might want to remember that."

"Wait just a second!" Pacifica exploded. "My new home?! You expect me to live with you in this weirdo underworld place?!"

"Well, if you'd rather try your luck on your own, be my guest." Stan gave her a hard glare. "That one-eyed flower wasn't the ONLY nasty thing down in the Underground. There's even worse monsters down here. And they won't hesitate to take your soul if they get the chance." He glared down his glasses at Pacifica, and she gulped despite herself. She grabbed her at the place on her sweater where her soul had just been, as if expecting it to be sucked away at any second.

"Trust me kid, I'm your best chance for survival down here. Now I'll say it again-let's. Go." Pacifica sighed and followed Stan through the door. Pretty soon, they'd reached a bridge.

"Now, to get by here, you need to flip a few switches." Stan explained. "But don't worry, I labelled 'em for you. I think you can figure out the rest." He crossed the bridge, and Pacifica looked over at the wall, seeing several switches along the way.

After they crossed a second bridge, Stan stopped in front of another door, looking expectantly at Pacifica. She walked over to the switch, raising an eyebrow.

"Flipping a switch? Puh-lease." She flipped it, and soon a loud 'thunk' was heard as the gate opened.

"You learn fast." Stan observed. Pacifica couldn't decide whether or not he was being condescending. "Come on, let's go to the next room." As they crossed into the room, Pacifica was surprised to see a training dummy waiting for them.

"What's THAT?" She demanded.

"Practice." Stan said. "Like I said, since you're a human in the underground, monsters'll try to attack you. They'll be looking for a fight. So you'll have to fight back."

"Fight?!" Pacifica's eyes widened. She had NO experience at all in fighting. There weren't any people up on the surface who'd dare thinking of harming her, due to her family's status. But down here, with monsters who'd try to take her soul, she had to fight for her life?! Her heart started beating faster.

"Don't worry." Stan encouraged her. "I've got some tips that'll get you out of ANY fight. Try talkin' to them, for one. Y'know, stall for time." He motioned to the dummy. "Try it."

"Talk to a dummy?" The idea sounded ridiculous. But Pacifica decided it was best not to say anything. She walked over to the dummy, raising an eyebrow.

"Um…hi? Nice to meet you-or whatever." She rolled her eyes. For some reason, this seemed to please Stan.

"Not bad." He walked off again, and Pacifica followed him into yet another room.

"There's another puzzle in this room." The goat man said. "Let's see if you can't solve it." Pacifica gasped as the image of her soul appeared on her sweater again.

"What the?! What's happening?!" She got her answer as what looked like a set of teeth with arms and legs jumped out from a bush.

"AHHH!"

"Relax, kid!" Stan shouted. "Remember what I told you!"

"Uh…your teeth are really shiny?" Pacifica said desperately, without thinking.

"Aw, shucks!" The toothy monster almost blushed. "Almost makes me wish I didn't have to fight you." He ran towards Pacifica, making biting motions. She screamed and moved out of the way, picking a stick up off the ground.

"Get back, you freak!" Her heart beat harder and faster than normal. Pacifica was scared out of her mind. "What do I do?!"

"Spare him!" Stan answered.

"What?!"

"Trust me!"

"Alright, alright!" Pacifica looked back at the toothy monster. "I…spare you, or whatever!" Immediately, the tooth monster stopped trying to attack her.

"Huh?" Pacifica watched in surprise as he walked off. "Did…that just happen?" Stan nodded.

"Your first fight in the underground, and you showed mercy. Way to go, kid."

"I don't understand ANY of this." Pacifica put a hand to her head, and Stan said

"Think of it this way. Life down here in the Underground is like a big…what do you call those things?! Video game. You can kill everything that gets in your way, or you can try and talk things out. As much as I'd personally like to lean towards the first option, I wouldn't suggest it." He looked down at her. "You seem like a good kid. I don't want to think that you'd be like…" He stopped himself.

"'Like'?" Pacifica prodded.

"Nothing." Stan shook his head, and Pacifica decided to drop it. But she got the feeling that there was something the old goat wasn't telling her. And since she was apparently going to be living with him from now on, for better or worse, she was going to get the truth out of him.

A/N: Yeah, this was short and lame. Sorry guys. I promise the next one will be better. Review anyway?
