Rescue (UnderFell!Sans X Reader Fanfiction)

~Chapter 18~

"Sans?!" You yelped. "How the hell did you find me?!"

"I could here you yelling from Undyne's door. How none of your friends didn't notice is beyond me." He chuckled bitterly. "What were you doing here anyway?"

You blushed. Standing abruptly you motioned at the echo flowers aggressively. "You didn't hear any of that?!" You asked.

"Any of what?"

Your face fell as you glanced at the blooms. They no longer repeated your words, nor the tune of memory. Hands balled into fist, you collected your phone and huffed, shoving past Sans and back out into Undyne's backyard. He didn't know what you were talking about. He didn't know what that place was. Was it even real? Had you just recorded those things yourself?

But that didn't make sense. Echo flowers repeated exact copies of what they heard. You couldn't make the sound of the guitar, nor mimick voices so flawlessly. Sans scrambled to catch up to you. You didn't notice as he walked at your side, attempting conversation. You muttered to yourself, brow furrowed as you tried to think of an explanation.

"Hey! Earth to pet? You there?"

You spared him a glance but couldn't help and roll your eyes. He was being annoying. "What Sans?" You growled.

"What's got your panties in a knot?" He scoffed, almost sounding hurt. "I haven't done anything."

You shook your head, curving a palm against your cheek. "Haven't done anything...." You mumbled. Realizing he'd never answered, you repeated your earlier question. "You never told me. How did you find me in there?"

Red seemed to dust his skill but he shrugged. "I saw a crack in the wall and heard your voice yelling through." He said.

You squinted, setting on him an accusing look. "You're lying Cherry." You accused.

He threw up his hands in defense as his expression turned sour. "Wow there pet. What's with the sudden hostility?!"

"You're lying!" You snapped. "When I stepped into that chamber the exit sealed completely. I sure as hell didn't push it open! How do you know how to open that door?"

He seemed almost inpressed. "I just did." He lied bluntly.

"Bullshit!" You growled. "Your voice was in the echo flowers! Echo flowers can only repeat what's been imprinted on them last. YOUR VOICE."

He rolled his eyes. "Well you can't exactly prove me guilty now can you?" He spit bitterly. "And who are you to ask?! Didn't you just stumble onto it yourself?"

"No! I actually didn't!" You yelled. Flushing, you took a breath and a step back. He knew something. He had to. "I had these vague flashes of something, it showed me!"

"Visions?" He asked, putting on his best bullshit face. "What are you, a physicic?"

You face was almost as red as ruby and you roared in frustration. "Sans that was your voice! You were singing this really old song that I love, and Frisk was sitting with us and we were having a good time! You were actually being a decent fucking person and I thought, 'oh, well maybe he might not be such a bag of dicks as I thought,' but clearly I was wrong. Because I'm getting all these fragments of memories I don't recall making, and I thought maybe someone else would know and help me but I understand now! Oh I understand perfectly! Down here it's everyone for themselves because lord forbid someone actually be kind!" Your voice broke and your nail cut deep into your stretched palms. "I'm sick of having these fragments I don't understand! So far the most honest thing in this godforsaken hell hole are those goddamn echo flowers! I just want to know what I'm missing. I want to know what those random pauses are, and what this weird ability has to do with my fate. Why are my friends hiding things from me?"
