An Internal Inferno

Chapter 1: The Morning

The one time Sans needed a reset, none came. The fallen human had almost been defeated by the monster king, only for the king to show mercy. What drove him to do it, noone knows, but the fallen human, Frisk, was allowed to stay underground with the monsters that were now thier faithful friends, living in the ruins with the old Queen, Toriel.

At this moment, however, Sans the skeleton was bent over a toilet wishing for a reset that never came. He felt unbearably ill. "Do skeletons get sick like this?" the stocky built skeleton asked himself as another round of nausea crashed over him. This couldn't be normal.

After what felt like hours, Sans was finally able to stand. His bathroom wasn't anything too fancy, the standard toilet, mirror, and bathtub. The white of the room normally made the bone-white skeleton appear more pale-blue in comparison, his magic showing through his pale complexion; however, when Sans caught a glimpse of himself in the bathroom mirror, he was so pale that he blended in with the steril white of his surroundings.

He had never been so pale before, his magic seemingly long gone from his cheeks. How could he fix this? Maybe he just needed food, he thought. It will restore his magic back to normal and he'll get better, right?

With a destination in mind, Sans tried to take one of his signature shortcuts. His body glowed blue until it flickered and went out, a wave of exhaustion flooding over the skeleton. He guessed he would have to walk.

-----------------------------------------------------------

Walking into Grillby's was like diving into a cool lake on a hot summer day, or walking into a bar after giving your brother an aneurysm because of your health. You can guess, Sans was feeling the latter as he sat on his usual stool. The quiet bartender examined the skeleton, silently, before walking over.

"Sans, the usual?" Grillby inquired.

Sans sighed, replying, "Give me the burg and fries..." He paused before adding, "... and a bottle of ketchup of course,"

Grillby briskly walked away to cook the meal, barely showing his quiet contemplation.

Sans sighs, putting his head down on the bar. He moves his hand, absentmindedly, to rest on his stomach. His blue ecto-belly was formed! He hadn't eaten anything yet, so why was his body using magic to form the unnecessary appendage?

Sans looked up to the sound of a plate clanking, right by his skull, onto the bar. Grillby gives off a soft crackle before finally speaking.

"What is on your mind Sans?" Grillby softly inquires.

"My stomach is a bit off. That's all..." Sans replied. He looked up to Grillby's face. He was concerned, Sans could tell.

Grillby starts, "Listen, I can close the bar early if you need to ta-"

"No, I'm fine Grillbz," Sans interrupts, "I promise."

"Fine," Grillby replies, "but I'm still closing at least an hour early." Sans sighed, nodding.

"Fine," he said, "only one hour."
