Determination (Sans X Reader)

•Chapter 3•

By the way! Before the chapter starts, •(y/n)• is like a nickname type of thing. Like if your name were Samantha, it'd be Sam or something like that :)

(y/n) POV

I started poking Sans' cheek bone in hopes to wake him up.

He opened his eyes, or should I say, eye sockets, after my sixth or seventh attempt to wake him.

"Oh, hey kid." He still looked a bit tired.

"Sup. I was just gonna tell you I was gonna go out and, y'know. Do what I gotta do."

"Ok," he said getting up. "I'll come with ya."

"Well I mean you don't have to if you don't want to. I was just letting you know that I was leaving."

"Nah, I'll come. I don't want you getting all bonely." I tried to keep a straight face at that bad pun, but Sans was staring at me with just about the biggest grin I've ever seen. That caused me to laugh.

"Well, tibia honest, I'd be fine!" I said after somewhat pulling myself together."

We went through the rest of Waterfall reviving all the monsters and laughing at our horrible puns.

Sans told me that there was just one more I needed to bring back, but I needed to be careful around her. She hated humans.

We stopped in front of a long pathway. It was dark, but by dark enough that i couldn't see. I picked up the two halves of the heart and soon a fish woman with bright red hair stood in front of me.  As soon as she saw that I was a human her look of confusion turned into an angry one.

She threw a blue spear at me and it barely missed. It skimmed my arm leaving a mark on it.

She threw another but Sans protected me, using the same magic he used on me earlier.

"Undyne, chill! She's here to help," Sans said to her.

She put her spear down. She walked over to me and I noticed that she was pretty tall. "Alright, human," she whispered to me. "You're lucky that Sans over there thinks you're cool cause if he didn't, then I would've killed ya."

"Oh..."

"But hey!" she returned to her normal tone. "Don't worry, we're cool now." she punched me lightly on the shoulder and grinned at me. I smiled back.

"So what's up?" Undyne asked Sans who was now standing right next to me. He explained to her how Frisk was hurting everyone and how I had the power to bring them back to life.

"Well, if you guys need anything - Sans, you have my number okay?" She started to walk back into her fish shaped house.

"Ok, see ya Undyne," Sans said.

"I'll see you two nerds later!"

Sans and I walked until we reached the end of Waterfall and reached Hotland. Sans had told me that Dr. Alphys' lab was here and it was one of the first things I saw.

"Here, follow me," Sans said. He grabbed my arm, causing me to blush a bit. We walked into the lab and I saw a huge screen.

Was that Frisk?

They had so emotionlessly killed a volcano like monster.

"Hey kid... you okay?" Sans sounded concerned.

Damn, I didn't even notice I was crying again. Sans inched closer to me and gave me a hug. I hugged back, sinking into him. He was surprisingly warm. Must've been because of his blue jacket.

I saw a yellow dinosaur monster come from what I assumed to be a bathroom. I tapped Sans' shoulder and he turned around to face her.

"Huh? Oh, hey Alphys," he said after letting go of me.

"H-hi Sans," she waved. "Who's this?" she asked referring to me.

"(y/n)," he simply responded.

"What's Frisk doing?" I asked.

"Well t-they're uhm, how do I say this - killing everyone." I looked over to Sans and I saw his eye flash the same blue when he first saw me.

"Hey, you okay?" I whispered. He went back to normal.

"Uh yeah," he responded flashing me a small smile.

I nodded. "Now, their determination is far too strong, it's enough for two people!" Alphys told me.

"So are they like, possessed or something?" I said with a bit of concern in my voice.

"Chara," I heard Sans mumble.

Alphys' POV

It's possible that Chara could've possessed Frisk. After all, Chara did hate anything living and breathing. She even tried killing Asgore.

So...maybe? I don't know. I don't want to tell (y/n) something wrong!

Sans' POV

(y/n) looked like she was really freaking out.

"Hey, buddy, it's okay," I said sitting next to her on the floor. She had her back to the screen which was a good thing. Every time she looked at it, she started crying.

She still had tears falling down her face so I just started rubbing her back in hopes to calm her down. She leaned her head on my shoulder and that blue blush started to come back.

Alphys had went down in her true lab to do some work. She left •(y/n)• and I here.

(y/n) fell asleep, so I decided to take her back to me and Pap's place. He was probably getting worried. I carried her the whole way back, she wasn't that heavy.

I put her on the couch once inside, then rushed up to my room to clean it really quickly. Once I was done, I put her on my bed and headed back downstairs to go to sleep.
