Regret (Sans x Frisk)

Chapter 4

~Sans's pov~

Thoughts raced through my mind, if I kill Papyrus I'll get the love of my life back, but I'll lose my brother; however, if I kill Papyrus I could tell her to reset. Force her to reset.

My face fell grim and serious as I shook Chara's extended hand, "Deal" I said flatly.

Chara gave me a mischievous smile, and before I could say a word, he disappeared.

I noticed something in the snow, something the shined in the light.

A knife. Chara's knife.

I picked up the knife with ease, and admired it, looking at the blood stained handle.

I smirked at it. Tonight.

I hid the knife behind my back and took a shortcut home.

I appeared in my messy room and silently hid the knife in a small pile of clothes.

I took quick strides to get downstairs and now only saw Papyrus and Undyne quietly talking to each other at the dining table.

When they saw me they both jumped up out of there seats and rushed towards me.

"Brother! You had us worried," Papyrus exclaimed.

I rolled my eyes and looked back up at them, scratching the back of my neck in an awkward manner.

"Uh, yeah. Sorry about that, I just had to calm myself down" I stated.

They both nodded, and Undyne let out a yawn as she said tiredly, "Welp, I need to go home, I got so tired scanning hotland, waterfall, and snowdin to find you."

She seemed slightly agitated.

Papyrus smiled and yelled out, "If you're so tired then you can just sleep in my room!"

Not giving Undyne the chance to speak Papyrus quickly grabbed her wrist and bounded upstairs.

I let out a quiet growl and scowled out, "Great. Might have to kill her too."

I sat on the couch, waiting for it to become night, or at least what we call night.

I tapped my hand on the table impatiently, watching a shitty rerun of a MTT game show.

After tonight I'll get Frisk back.

I smiled at the thought, and turned my head towards the kitchen, Papyrus had gone to bed, and Undyne was still sleeping.

Now's my chance.

I smirked and quietly made my way upstairs and into my room.

I grabbed the knife and ran over to Papyrus's room.

I quietly turned the knob and pushed the door open.

It made a loud creak that felt as if it would never end.

I quickly stopped pushing the door, and waited for any movement.

Both of them didn't move.

I silently slid through the small opening and into the room.

I saw Papyrus on the floor with a thin blanket on him and a lumpy pillow under his skull as Undyne was comfortably sleeping on his race car bed.

I chuckled darkly watching as their chests rose and fell as they breathed.

I stared at Undyne.

Her first. She'll be the biggest threat. I carefully stepped over Papyrus and hovered over Undyne, gripping the knife.
