Sans:
        "Knock knock!!" I said as I knock on the door.

          I heard Frisk's voice. "Who's there??" I felt her voice closer to the door.

         "Let's." I answered.

         "Let's who??" She replied confused.

         "Let's go back Frisk." I said and opened to the door to find Frisk right in front of me in a ghost home.

         "S-Sans?? How did you get here?" She asked me.

"Don't ask, let's go." I grabbed her hand and we started walking.

"W-wait!!! Bye Nabstablook!!" She waved at the ghost.

"Bye Frisk!!" He smiled and waved back.

I teleported her and I back home.
