Stuck in Between (Reaper!Sans X Reader)

~Chapter 12~

You were riddled with anxiety as Papyrus pulled you through Waterfall. Frisk was being hauled in his other hand as you stuggled to keep up. Seeing the familiar walls of the damp scenery offered glimpses of memories, but having it so suddenly around you after the previous nights' memory scared you.

"Papyrus, I don't know if this is such a good idea." You said again, the tenth time in the past seven minutes.

"Nonsense human! I cannot have my best friends not be best friends! That would be madness!" Papyrus explained.

"But won't she want to collect our souls to break the barrier?"

"Of course she will! But I will not let her kill you, at least not until you are best friends."

"Paps..." You groaned, hanging your head. "I don't think I can handle it if we're engaged in a fight. I'm, uh, sick! Yeah I'm not feeling too well right now and-"

"PAPYRUS! WILL YOU HURRY UP?!" Another voice called, both familiar and worrying.

Welp, I'm fucked.

Hades cawed gently at you and you smiled, stroking his feathers. "Good crow. When I die, I'm leaving it all to you." You joked.

He cawed repeatedly as he jumped from leg to leg, making you snicker. Though it was a small, meaningless gesture, it lifted your spirits.

"Undyne! I'm bringing some more people to our lesson!" He warned.

Undyne's head of red hair bobbed in view. She looked so similar to the memory, but she smiled. It seemed wrong, even for a pacifist run. You glanced at Frisk and saw even he was in confusion as well. Though it was unfamiliar, he shrugged and smiled, increasing pace so he was leading rather than Papyrus.

You flushed. "Behold! These are my two human friends!" Papyrus boasted, lifting me so I stood front and center next to a beaming Frisk. "They're names are-"

"Frisk and (Y/N)!" She yelled, a grin over her face. She took our hands and shook them aggressively, almost pulling our arms out of socket. "I'm so happy to meet you guys! We're gonna be best friends!"

"How did you know about us?" You asked, awestruck.

"Oh! Well Papyrus' bro Sans came by yesturday and told me you guys fell down recently. At first I was totally ready to destroy you, but then Sans said he knew I wouldn't be able to find another solution. So to prove him wrong, we're gonna be BEST friends!"

Your mind presented vague memories of this happening in a different way. Frisk sent you a happy look and you sighed, smiling as you raised you gaze to meet Undyne. "Well, I'm happy you think so."

"Yeah!" Frisk cheered. "I can't wait!"

You snickered and ruffled his hair. Undyne laughed heartily and scooped us up, one under each arm. "Now we can cook!"

Papyrus raced after us, smiling happily with a victorious "NYEH!"

You heaved for breath, clutching a firm hand over your chest. Red was splattered all around you and Frisk had shrunk away, shaking. Undyne's grin curled violently, an turquoise spear balanced perfectly in her hand.

"Undyne stop!" You cried, fear in your voice. "There won't be any more tomatoes left for the sauce!"

She turned to you and cackled. "Don't worry (Y/N)! There's plenty more in the fridge." She reassured.

"Those are the ones from the fridge..." Frisk groaned. "Those poor vegetables."

"Fruits." You corrected.
