Gaster Blaster Sans X Reader

Part 3

"Sorry I scared you there kiddo" Sans sighs.

You continue to back up, your hand over your mouth. You back up until you trip and fall over some large cables and wires.

"Listen, I never meant for that to happen, and I-" Sans starts to say, but you cut him off.

"I-I just n-need a moment" you say, your breathing heavy. You were never really that scared about the rumor, but now you are scared, scared about what might happen next.

Sans looks at you, upset that he scared you. He then puts his head down, hoodie up, and walks away. You watch as he goes into a side corridor. You look around and see that you're in some sort of laboratory. Then you notice that the other monster is still here.

You try to calm yourself and get back up. The yellow monster comes over to you with a shy smile on her face as she pushes up her glasses.

"H-hello, I'm A-alphys" She says.

"y/n" you respond. You are feeling less shaken, but you still don't know where you are.

"S-sans said he met you i-in the park y-yesterday" Alphys says. You nod. Alphys seemed pretty nice, but then you wondered if she could also . . . you didn't want to finish that thought.

"Where am I?" you finally ask.

"Were in t-the Hotland" Alphys responds. You aren't sure where that is. "It's i-in the Underground" Alphys finishes. Now you understand. But why did Sans take you here? No, it must have been a mistake. Either way how do you get out?

"I-I'll go talk to S-sans" Alphys says. She starts to walk away, but you call for her.

"Hey, Alphys, how do I go, you know, back to the surface?" you ask her.

"I-I'll go talk to S-sans" Alphys repeats. She goes into the corridor Sans went into.

So here you are, stuck in this laboratory in the underground, alone. Definitely NOT how you expected today to go. You were a bit scared to explore, but then again you'd get bored just sitting here. You had no idea how long the two monsters where going to be gone. You decide to explore the area you're in, not wanting to get lost.

You notice a whiteboard with a large drawing on the wall with a desk in front of it behind you. The desk has piles upon piles of papers and notes. You go over to examine the whiteboard. At the very top it has Gaster Blaster written in large letters like a tittle. You examine the picture of what you guess is the Gaster Blaster. At the bottom there are pictures of Sans and next to him is the Gaster Blaster's full body. It doesn't look like the humanoid you just saw, but you assume that's what Sans could look like.

You start to skim the notes on the board. Some of them are in another language. Unstable, uncontrollable, test has failed. Most of the notes make Sans look like an unstoppable beast. You see a little device on the table with more notes. The notes state that the device is a "stabilizer". The rest is hard to read.

You back away from the table, more confused than ever. Next to the desk and whiteboard there is another corridor. It isn't the one San's and Alphys went down, but you still just want to look. The flickering lights catch your eye, followed by the large scratches on the wall. You look at the floor where tiles are ripped up and broken and scratched. At the far end of the corridor you can see large streaks of charred wall, like there was a concentrated fire in those spots.

"y/n? y/n!" You hear Alphys calling for you. You step out and walk over to her.

"Yeah?" You utter.

"D-do you have t-to go home any time s-soon?" Alphys asks nervously.

You pull out your phone to check your calendar. "Not really, why?" You respond.

"Oh, umm. I d-don't think Sans is ready t-to take you back. S-so you're kind of . . . here . . . b-but I promise it won't be for long!" Alphys says.

"What?! You mean I'm stuck here until I can be brought home by some uncontrollable monster?" You respond annoyed.

"Y-you really shouldn't c-call Sans an uncontrollable monster" Alphys tells you.

You sigh. You really hopped Alphys was right and that this time here would be short.
