{Met you in the snow.}

[The storm.]

It's a new morning in Snowdin, yesterday night was a stormy night. There was some damage done to houses and monsters were already busy helping bruised, innocent souls. Sans, also known as the lazy but popular skeleton that always makes puns, came to check on the village. 

''Howdy, Toriel. The damage tonigh was pretty bad huh? I hope nobody broke' a bone'. . .'' 

 Toriel would slightly laugh at the joke and had a gentle smile on her face, looking down at the skeleton that just made his first pun of the day. 

''Yes Sans, the damage was indeed bad. Some poor monsters were wounded but are luckily now being treated. The storm is not going gentle on us these days.'' 
Sans sighed while looking around. ''Well, i should go and help a little.'' He waved at Toriel as she waved back. With his hands in his pockets he walked through the village, leaving footprints in the snow. Some destroyed houses caught his attention as he checked if any monsters was stuck under the bricks, wood or anything else. 

He continued his journey, but saw a black figure for a second before it ran off.
Sans got confused and ran after it, he didn't trust it. 

...

He didn't know if the black figure was dangerous or anything.
Maybe he had something to do with the storm? Maybe he killed people while the storm was breezing through Snowdin.

....
Who knows.

Sans kept on following the figure until he lost it. He panted while looking around, staying alert at all costs. He sighed. ''Where did this little thing go? Just wait till i find you.''
He threatened... No response. He groaned, he got more and more irritated as time passed while searching. He did not wanna give up tho, he needed to know who this person or monster was, if they were a threat yes or no and if they were planning something. He noticed footprints in the thick snow and looked at them... Human footprints. Sans huffed and followed the footprints through a long hallway, his hands were still in his pockets as he could barely see in the darkness.

He stayed alert because of that, he didn't know if anything would jump out of the darkness to attack him, or maybe kill him. When he reached the end of the hallway he saw light again, he blinked twice before seeing the black figure infront of him. ''Hey, you.'' he said and walked to the person, but they got shocked and made a run for it. ''Get back here, pal!'' he snarled and ran after the figure, his hands out of his pockets this time. He threw a bone attack to lock him up but missed, he cursed at himself and continued the chase. The human was fast, Sans had troubles keeping up with them, but still managed to get a head to head chase.

''Cmon buddy, don't run from me. You won't win this.''
Sans offered, the running figure didn't answer and ran in another hallway. 
Sans would groan but still followed the human. Suddenly the figure turned and attacked Sans with a knife, pure self defense. Sans threw another bone attack, one managed to hit the human and they got blown away. Their soul flickered as they suddenly got lifted up by the skeleton with his power. His hand turned from a fist to a flat hand and the human went flying. Sans took a breath and walked to where the human flied to. His hands were in his pockets again as he walked up the cliff, the human was laying there on the cliff while struggling to get up. The human was right at the edge of the cliff but luckily didn't fall.

.....

What will happen next?
