The days bled into the weeks. Time wasn't really a concept to you anymore. You would float around, wandering aimlessly until Papyrus would drag you back to this grim reality you've come to accept.
Sans couldn't see you, but he seemed to hallucinate when seeing Papyrus. You would frown when seeing his eyes. What were once kind and caring eyes were now full of insanity and a lust for revenge.
You didn't die by his hand, not like Papyrus. You died by the human, left alone in the snow as you watched your body slowly turn to dust. Sans had found you at your last threads, far too late to be saved. Leaving nothing but your (article of clothing) behind, you now have to watch as Sans descends further and further into madness.
There were some days where you wish you could help him, perhaps lead monsters to him or hurt the human like they hurt you.
But alas, no one seems to see you other than Papyrus.
It was just another day, you were following Sans and Papyrus around. Sans seemed to be a rare, better mood today, his gaze not as crazed and his insane smile lessened into a more neutral smile.
You and Papyrus floated around him, occasionally pointing at spot you had better memories at. Like the path that led to the spot you three once built snowmen at. Papyrus' muscular version of himself and Sans' snowpoff were gone, but the memories were not.
You floated over to a low hanging branch outside of Snowdin, a memory coming back to you. You would sit on it as you waited for Sans and Papyrus to return home when you were younger, jumping off of it, flinging snow everywhere, and running to them the moment you saw them.
You sat down on the branch, imagining your brothers, alive and well, walking towards you like before.
You noticed the pause from Sans immediately, noticing the branch was swaying just slightly.
You've seen Papyrus manipulate a few things here and there, perhaps you're able to do it too?
You got down from the branch, watching as Sans focused on the sway of it intensely. You floated away from it a bit, not wanting him to begin to think it was just some sort wind.
Looking down at a patch of undisturbed snow, you crouched down and began drawing in it, drawing you and your brothers.
Glancing up at a tap from Papyrus, you saw Sans at your side, a genuine, warm smile on his face.
"So, you are still here."
