(Papyrus POV)

I called up to Frisk and Sans, who were playing a video game upstairs.

"Sans! Frisk! I made spaghetti!" I said. They paused the game and came downstairs into the kitchen to eat.

"Hey guys!" I heard another voice say. It was (y/n).

"Human! Have you come to eat this wonderful pasta with me, Sans, and Frisk!" I said, excitedly.

"Nah, I made lasagna at the house. Chara is playing Minecraft again. I need to talk to you alone for a bit about something," she said. I grinned. It was about time for Christmas to start, so I assumed it was a discussion about what presents to buy for everyone.

"Okay! I'll be right back Sans!" I said, walking towards (y/n), who was smiling.

"I'll try some spaghetti when we get back," she said, taking me out the door. We went around to the back of the house.

(Tyson POV)

I led Papyrus around to the back of the house. This was going much easier than I had expected.

"So, what gift do you think we should get Sans for Christmas?" I said. He grinned.

"New slippers and a sweater!" He said, joyously. I smiled.

"That sounds perfect! I wanted to give you your gift early, though. Cause your my best friend!" I said. I reached behind my back to pull the knife I had out. Papyrus was filled with joy.

"Early gifts! It's a week before Christmas!" He said.

"I know, but you are very special! The brother of my boyfriend deserves the best," I continued. Papyrus took notice of the knife.

"That knife! I needed a new one to help cut tomatoes for the spaghetti sauce!" He said. I smiled.

"Great! But, that's not the reason I have it," I said. Papyrus looked at me confused.

"It was very knife knowing you Papyrus!" I said, quickly slicing through his armor. His expression was of pure shock and betrayal as his skull hit the ground with a thump.

"T-that...wasn't what I had...expected..." He said. He looked at me in terror.

"(Y-y/n)? Why?" He said. I laughed.

"Its Tyson, dear Papyrus!" I said, resting my foot on the skull. Papyrus was terrified.

"D-don't-" he started, but I had already started applying force. I crushed the skull into dust, watching it fly away in the wind. His scarf lay abandoned on the ground.

(Your POV)

"PAPYRUS!" Sans shouted, running to the screen. He banged on it hopelessly.

"Papyrus, no! No no no!!" He continued. You were sobbing on the ground again. Tyson laughed maniacally in your mind, the horrible laughs echoing, teasing your anger.

"Stop laughing!" You screamed. Sans was still crying.

"Your still alive! Ha! You won't be for long," Tyson said. You growled.

"Stop killing my friends!" You yelled again. Tyson laughed even more.

"I don't think so," he said.

You watched as he left the skeleton brothers' house toward the Dreemurr's house. He proceeded to kill everyone in the house, starting with Asgore and ending with poor Asriel. You were crying all the while, watching as your friends were killed one by one and their dust left scattered about the floor. You knew he was going to kill Alphys and Undyne next, along with every monster on the way.
