Summary
He danced with her in the living room as he sheltered in her house from the rain. However, unbeknownst to Sans, the roof was sheltering him from something far more detrimental- a horrible fate that was fast approaching. Soon enough, he'd realise that he danced for too long, left her house too soon and neglected to confess the truth to Toriel before it was too late.
Soon after she was snatched from his reach, she was replaced with something else.
It wore her face. Her laugh.
It stole her jokes. Her warmth.
And that wasn't all it took. -

Summary
There was no hope.
There was no way out of this place. Sans knew that from the depths of his soul- he couldn't escape on his own. But without any way to contact anyone and no knowledge of where he's trapped, all he could do was try to survive... or maybe just hope for death.
No more resets, after all.

Summary
Mafiafell take I had made.
Constant war meant the development of new methods of destruction. Hopes of catching everyone else off guard with a weapon they couldn’t combat or find a way around just long enough to stay on top until the newest shiniest thing made its way to the market. Mechanical enhancements, biological modification, higher powered weapons. Its a constant struggle for king of the hill, a never ending toppling and growing market with worse and worse.

Summary
Ah yes. The classic ‘’Heather’ convinces the skeletons you’re an evil human so now it’s a EVIL reverse harem’. Right?
Oh? But what’s this? A TWIST?
Sans couldn’t live with himself after what happened to you, going near insane after you’re gone. So behind the others back he uses the machine to undo what he did, except it didn’t. He can still feel his sins crawling on his back.
Oh well, it’ll all be worth it once he has you back in his cold hands again. Screw the other skeletons.

Summary
Adults lied. It was what they did.
They said they would take care of you, but they didn’t. They said they would be there, but then they died. Sans had gotten used to it.
But Papyrus shouldn't have to.
And if Sans had to take matters into his own hands in order to make sure he kept his promise to his little brother? Then so be it. It was Sans and Papyrus against the world, and some gangly skeleton with gentle sockets and a weird font wasn’t going to be the one to change that.
—
“Sans, wait—! Please, let’s just talk for a moment—!”
“no way, you creep! leave me alone!”
“Excuse me? I’m not a creep! I just wish to talk! You have many people very worried about you—”
“nah, you’re not excused. gimme 500 g and then i’ll consider it.”
