Continue walking.
Sans' usually lazy attitude had made place for a stiff, somewhat tense one. His face was completely devoid of emotion, and instead of his sluggish way of walking, he moved in a pace most people would consider to be normal. Maybe even a bit faster than normal.
Keep going. Your destination is near.
He currently found himself in Waterfalls, walking the path that would eventually lead to where he once pranked Frisk with the classic telescope trick. He could still remember her amused reaction. The paint on her eye had barely bothered her.
There. Mere steps ahead.
But he was not here for the telescope. No. He was here for…for…
He blinked.
What was he here for?
Something in the corner of his eye caught his attention. He looked over, and to his horror he saw a ghostly white door in the wall to his left. In addition to the soft, tranquil light it radiated, Sans felt an energy coming from it that messed with his senses. It made his vision blurry and his ears ring, with a rising headache as a side effect. That door's presence, its very existence was an anomaly. It didn't belong, yet here it was.
The Door.
Panicked, the skeleton grasped his head. What had caused him to come here? He could remember the last few minutes, but it was as if his mind had been…influenced by…something.
I have reached out to you. Have called for your aid. I need you to trust me. Your assistance is essential.
Sans took a step back. That voice… That eerie, dreadfully familiar voice had been in his head the entire time he'd been…possessed. The two phenomena were connected. Whoever that voice belonged to was responsible for leading Sans here.
Please consider your actions. They will heavily influence imminent events. If you enter that door, it will allow me to help your friend. If you do not, I must reach out to her personally.
Trust me. Trust yourself.
Those two last words finally allowed Sans to understand.
His eyes widened.
"no…" he muttered.
Help me. Help your friend.
The skeleton let out a raspy cry, turned around and ran back to where he came from, shutting out the voice as he fled from the nightmarish door. He ran all the way back through Waterfalls, eventually reaching Snowdin. Once there, he went straight for his house, ran inside, turned around and locked the door behind him.
He put his back against the door, out of breath, slowly sitting down on the floor.
"SANS!" Papyrus called from the stairs. He immediately made his way down and to the door, kneeling in front of his brother and grabbing him by the shoulders.
"SANS!" He repeated. "OH MY GOODNESS… SANS, TALK TO ME! WHAT HAPPENED? ARE YOU ALRIGHT?"
Sans, who was still out of breath, struggled to get any words out. "whuh…whoa…i…i can…can…"
Papyrus waited until Sans had gotten his breathing steady again, which took a while thanks to the shorter skeleton's lousy physical condition. When his breathing was normal, he began to talk.
"he…he took me there…"
The younger one tilted his head. "WHO TOOK YOU WHERE?"
Sans opened his mouth again, hesitated, and spoke. "i…i was brought somewhere. i mean, it was my body that moved, but not my mind that controlled it. at least not completely."
"YOU…YOU WERE POSSESSED?"
"i…paps, i…heard a familiar voice. his voice."
Papyrus' confused look made place for a shocked one, and the tall skeleton froze upon realizing what Sans was implying. "SANS…ARE YOU TELLING ME…?"
Sans nodded. "yup. our old friend is back. and he's apparently grown more powerful during his absence."
