OK, this idea popped into my head and I really want to put this out there. Do not question me about it please. Still, this will not be apart of Time Lines… Unless I get a massive urge to put it in. But I will be calling this AU by "Gumdrops" because I feel like it. So if the Sans from this AU ever gets put into Time Lines, he will be titled "Gumdrop" Sans. And no, this isn't a candy wonder land thing.

Well enough of my ranting! I don't own Undertale.

Chapter 1- The Past is Back

"SANS?" called Papyrus's voice from the living room. It had worry mixed in it. Well, the tall skeleton did have a reason to worry about his older, but shorter, brother.

Sans groaned. He did not want to get out of bed. Had a reset happened?

"Sans, you need to get up, we can't get Papyrus worried over nothing..." came the small voice of a certain potted buttercup.

No, there hadn't been a reset. But Sans still didn't want to get up. Who knew if a new human had fallen into the Underground? No, Toriel would have notified Papyrus at least.

"Sans, wake up, please..." Flowey's voice whimpered. Through the two long years that had passed since the incident, Flowey had grown more feelings other than fear~his first emotion due to Chara~as well as grown to be Sans's moral support. Not only did the short skeleton need it, it was the way Flowey kept himself in check.

"fine, i'll get up..." Sans muttered, sitting up and rubbing his eye sockets. He then, slowly, got out of bed. Since he was wearing his shorts and t-shirt already, he put on his blue jacket.

Picking the buttercup's potted self as he left his room, Sans traveled downstairs. Papyrus, though obviously relieved that his brother hadn't fallen down during the night, still looked worried.

"SANS, THERE IS SOMETHING THAT YOU NEED TO KNOW," Papyrus said, as softly as he could.

Sans, fearing that Chara had returned in the body of another human, perked up, his magic slowly taking the edge of his tiredness.

"UNDYNE WENT TO SEE FRISK'S GRAVE LAST NIGHT, AND ALMOST INSTANTLY CALLED ME WHEN SHE GOT THERE," Papyrus continued. "SHE SAID THAT SOMETHING OR SOMEONE HAD DUG UP FRISK'S BODY, BECAUSE THERE WAS A HOLE IN THE GROUND AND NO SIGN OF THE HUMAN."

Sans could feel anger burst through him. Though, unnoticed by all but the flower in his skeletal hands, his HP had risen a notch. Flowey, though hiding a small intake of air at the surprise, turned to Papyrus.

"Was there any sign of a shovel?" Flowey asked, also angered by the fact someone had stolen the beloved human's body.

"ACTUALLY, NO," Papyrus said. "UNDYNE SAID IT LOOKED LIKE SOMETHING HAD DUG OUT FROM UNDERNEATH THE GRAVE, BUT SHE COULDN'T FIND ANYTHING SUPPORTING THAT, THOUGH THERE WAS A SMALL AMOUNT OF MAGIC RESIDUE AMONGST THE SNOW."

"flowey, it looks like we have a monster to punish," Sans said slowly. This earned a small, though muffled, gasp from said flower, and a look of pity from Papyrus.

Sans couldn't forget the kindness of a human that the tall skeleton had barely knew, who had saved him from a demon called "Chara" and sacrificed herself to keep them all safe. The memory was still fresh in his mind, even after two whole years since it happened.

Flashback

Sans bolted through the snow, Toriel a few paces behind him. Somehow, she had survived Frisk's~no Chara's~slaughter in the Ruins. At the moment, they were going as fast as they could to try to save Papyrus.

Sans burst in the clearing, expecting to see a red scarf amongst the snow. But, as Toriel entered the clearing, was momentarily shocked, and confused, by what he was seeing.

The human seemed to be fighting with herself, two different voices coming from her lips.

"No! I'm not letting you kill anymore people!" yelped the softer, and more familiar voice of the pacifist, Frisk. "They don't deserve that!"

"Give me back control of the body!" cried the bolder, and more evil voice of the murderer Chara. "You cannot stop me!"

As the fight between spirits, between two different souls of determination, went on, Papyrus noticed Sans and Toriel.

"SANS, HELP! I CANNOT FIGURE OUT WHAT IS WRONG WITH THE HUMAN!" Papyrus said, as softly as he could. "ONE MOMENT THEY WERE SMILING EVILY, BRINGING THEIR KNIFE UP TO SWING AT ME, THE NEXT THEY WERE CRYING AND YELLING AT SOMEONE CALLED 'CHARA' TO STOP!"

"C-Chara?" murmured Toriel, obviously shocked at this. "B-but she died years ago..."

"well, hate to break it to ya, but chara is the thing that's controlling the human at the moment," Sans said slowly. "hey, kid, don't give up! you've got to stay determined!"

The human sunk to her knees, tears coming from her eyes in small streams. "I-I got control..." she said. "But I don't know how long I can hold Chara back…"

"My child, is Chara really the name of the spirit that controls you?" Toriel asked.

The human nodded. "I-I need to tell you guys my real name… It's Frisk…" the human's pose slumped for a moment. "I-I can't keep control for much longer…"

"is there a way to stop chara?" Sans asked.

"The only way to stop her..." Frisk said softly. "Is if I die and not let her reset the time line anymore..."

"T-TIME LINE? RESET?" Papyrus asked. "SANS, WHAT IS THE HU- FRISK TALKING ABOUT?"

"she's talking about the deja-vu that everyone's been experiencing..." Sans said slowly. "The reason i didn't want you to fight her in the first place. we got to stop chara or else she'll take control of frisk and commit genocide."

"B-but we can't just kill Frisk!" Toriel stampered.

"N-no… it's OK, m-mom..." Frisk mumbled. "I-I want you guys to live in peace without Chara destroying it… So, since it's the only way, just kill me."

Sans looked at Toriel, Papyrus, then at a new arrival. Flowey had popped up, seemingly confused… and scared?… by what was going on. But the flower said nothing.

"well, if no one else is going to do it..." Sans said. "i guess it's going to have to fall on me… sorry tori, but it's the only way."

In mere seconds, Frisk was impaled by bones. She gave a soft, genuine smile. Blood ran down her chin.

"Sans..." she said, as her breathing got harder. "T-thank you..."

And then she fell into the snow, which was stained red from her blood.

Toriel and Papyrus weren't the only ones to cry. Sans, though hiding it, let a few glowing, blue~the same color as his magic~tears run down his cheek bones. He did, however, notice Flowey crying himself.

End of Flashback

/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/

Sans shook himself, mentally, out of the memory that plagued him. He had a monster to punish, and a body to find.

In his hands, with a scarf wrapped around his stem, Flowey looked up at the skeleton he could practically call his friend with sadness. The last time someone had tried to mess with Frisk's grave, for her soul which had never left her body, Sans had tracked them down in a mere two hours, and almost provoked a fight, had it not been for Alphys breaking it up before it started.

They had arrived at Frisk's ruined grave, the tombstone jutting at an odd angle in the mound of dirt around the grave. Like they had heard, the two unlikely allies did not see any sign of the human's body besides a few tattered pieces of cloth.

Flowey was the first of the two to notice the magic residue in the snow. "Red magic?" he asked to no one in particular. Though, Sans perked up at that. "Well, we've got a trail."

Sans looked at the residue. He, too, saw the trail it made.

"looks like we're following it," mumbled the short skeleton.

/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/

It took them an hour to get to were the trail of residue became uncovered footprints. Flowey, confused by this turn of events, had wanted to stay to study the footprints, as they were that of a monster with five toes. But Sans pressed on.

Eventually they got to a clearing. In the clearing, was a skeleton woman, unconscious, laying in the snow. Both monsters momentarily stopped and did a double take. No, they weren't imagining it.

The skeleton woman was wearing the tattered remains of a blue and purple striped sweater, and blue shorts that seemed to be falling off her hip bones. On her hand, a mark of where something had cut the bone into a heart shape. Next to her lay a small, unbroken stick, much like the one Sans had once seen Frisk carrying before Chara had taken control.

One thought passed through Sans's mind.

Had Frisk… become a skeleton?

The feels! OK, that was a long chapter, but I just had to get the whole thing in. Yes, I know I might be doing something others' have done, but I'm doing it differently.

If you liked what I have so far of Gumdrops, please leave a review of: the part you liked most; which character I wrote the best; reaction to Flowey having feelings; or anything else!
