Summary
"You've all seen the happiest outcome. Neither of them could fix the machine, no matter how hard they tried. Nobody can."
Sans thought he could be happy in this world. And for a while, he was. He genuinely was.
But after waking up with knowledge he doesn't even remember getting, he started to think that maybe this world isn't as real or safe as he thought. So he resorted to trying to get his brother and himself out of there at any cost!
Any cost.

Summary
It's well past midnight, and Sans still hasn't contacted him. Papyrus, while searching every nook and cranny in Snowdin, makes another call, his phone rings once, twice, thrice… and nobody picks up. Just what in God's name could possibly be holding up his brother tonight, and why didn't he bother to tell him anything about it, after he had explicitly promised to…?
Then, to his surprise, a familiar golden corolla appears in front of him - but not for the reasons he'd hope.
"Papyrus! Hurry! Your brother's in big trouble!"

Summary
****Tags will be updated as story progresses or as I think of things****
W.D. Gaster is a mad man, if you ask his scientists. Rumors fly around the lab, circulating through New Home. Hearing voices, talking to air, keeping private projects locked in hidden labs under security so thick not even the King has the keys. After his disappearance, the CORE’s Central Labs get shut down. Permanently.
Twenty years later, during the final shutdown of the Underground’s camera systems, there’s something spotted. Someone spotted.
Broken, beaten, quiet. A shell of a man previously full of an infectious, whirlwind energy.
What…happened?
