Don't let go: Undertale and Underfell

Chapter 5: Getting info and work

(UF Sans P.O.V)
I stayed on the roof for a few hours until I decided that I better head over back to Grillby's and discuss the problem at hand. I jumped down from the roof and onto the snow ground, landing onto my feet. I wiped some of the snow from my jacket and started walking towards Grillby's. When I got there, I opened the door and I immediately noticed that there was nobody was in the restaurant except Grillby. He immediately looked up at me and I gave him a nod.

"I told ya I would be back." I said with a smirk. He nodded at me and I knew he didn't speak much so I guess I would be doing most of the talking.

"So, what exactly has been going on? Have you seen Sans much?" I asked skeptically.

"Not much. But the times I did, he would always talk about her all the time." Grillby said quietly. I nodded and sighed.

"I just don't know how to do this. I know I have to bring her back. I just don't know how." I mumbled. The more I thought about it, the more I'm realizing that I'm caring for Frisk more and more. How's that happening?

"Well, that's all the info that pops into my head. I'm sorry I couldn't give much more assistance." Grillby said quietly. I lifted my head and grinned.

"Nah, you're fine. I think my best bet is to talk to Undyne." I said, realization coming over me like a bullet. He nodded and mumbled a 'good luck'. I gave him a 'thanks' and teleported inside Sans's house, scaring the crap out of Alphys. I chuckled and look over at Flowey, who was smirking.

"P-Please don't do that!" Alphys said, adjusting her glasses.

"Heh, sorry about that." I said, chuckling. I looked up at Undyne, who just walked in with a raised eyebrow.

"I have an idea on what to do. But follow me down to his lab." I ordered towards her.

"Wait, really? That's the first good thing I've heard in awhile." Undyne said quietly. I rolled my eyes slightly and I teleported us both at the back of the house and opened the iron door, making our way down the stairs. I've got to think fast here. What can I do? Undyne turned the lights on and I immediately went to the computer and started typing away on it.

"Alright Undyne. I need you to tell me everything that has been happening before you contacted me." I requested, not taking my eyes off the screen. She sat down in a chair and sighed, head hung low.

"Well, let's see here. Everything was going ok that day before we found her dead. Sans couldn't find her anywhere, so he was getting worried. He had asked me to come with him and try to find her. We both looked everywhere that day, we even asked people if they had seen her that day. But, nobody said anything really. They said they hadn't seen her. This started worrying us. We searched almost the whole underground and we still couldn't find her. But until we reached deeper into Waterfall." Undyne trailed off. I lifted my head towards her and raised an eyebrow.

"What happened?" I asked impatiently. Undyne bared her teeth slightly at me and looked down.

"When we got there, Sans went on ahead while I trailed behind. The place was slightly near the trash pit, but still quite a distance. When we got far enough, Sans froze. I ran up from behind him and saw what he froze at. Frisk was laying there, severely injured and laying in her own blood. At that moment, it felt like time had stopped around us, but I knew it hadn't. He was kneeled beside her in a matter of seconds, left eye flaring blue. I ran over as well, dropping dead to my knees. He was sitting there, holding Frisk in his arms and tears falling from his eyes. He begged and begged for her to wake up, to be ok, while neither of us noticed that her heart came out and was hanging over her head, slowly cracking. Tears were threatening to fall from my eye, but I wouldn't let them fall. I had to stay strong while I needed to get help, but what and who could help with this? At that moment, we both knew that she probably wouldn't be reloading or resetting. We both just sat there, the only noise around was the quiet water and Sans begs. But... At that moment... Her heart broke into a million pieces." Undyne wiped her eye slightly and sighed. I stopped what I was doing and looking at her in disbelief. I wasn't expecting that. What could have happened? That just made me continue to work harder on finding a way to bring Frisk back.

"What... Happened next?" I asked slowly. Undyne looked up and gave a slight glare.

"Nothing much. Just since then, Sans has been the same way as he has been now. That simple." Undyne said slowly. I nodded and continued working. Come on Sans! Think! What can I do for Frisk? What can I do for everyone? What can I do for... me? How can I... Wait! That's it! A regeneration machine! How could I not think of that earlier?!

"Wait! I have an idea! This may sound so ridiculous and unbelievable, but it's true!" I exclaimed. She lifted her head up and raised an eyebrow.

"What?"

"A regeneration machine! I could bring her back! It could heal Frisk's soul!"

"No way... dude, that would be great, but..."

"No I'm serious! I-"

"But damn it, dude! Are you sure it would work?!" Undyne demanded, shooting from her chair, starting to get angry. I shot up to and started to get angry too.

"Yes! That's what I'm saying!" I yelled back at her. She sighed and calmed down, lowering her head.

"Sorry man, I just..." Undyne trailed off. I calmed down too and got her to sit down, patting her back.

"You'll be ok. It'll be alright. I'll bring her back if it's the last thing I do. I swear. And I don't usually make that kind of promise since I'm from Underfell, and neither would Blue, most likely, but I told you, I swear." I said, my eyes went white to my left eye red. Undyne looked at me and nodded her head, grinning widely.

"Thanks man. And I know you well enough that when you mean something, you mean it." With that, she left and I started working on the project that will probably hold the future of Undertale.
