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.

Frisk had a plan for everything. A plan for their education, a plan for their career, a plan for the next thirty years of their life, and exactly how they were going to free monsterkind from humanity once and for all.
But Frisk didn’t have a plan for this.
What is there to do when your body is dying and this time you can’t time-travel your way out? What can you do when all of the secrets you hide away in the back of your mind are coming out, ready to destroy the life you built? Frisk doesn’t know. So they do the thing they know to do best—They run away.
Its never too late to change. Its never too late to be better.
Will Frisk remember who they really are, and love themselves again? Or will they let hatred consume them?
One thing is for certain. Their friends wont let them throw their life away. No matter how hard it becomes or how painful the journey is.

As you get friends and foes alike, you notice that not everything you know is trustworthy. Especially when you're a little lost skeleton with questionable ability to feel.

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 sciencists. 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?
