Story title: Oops

Rated: K+

Summary: An out-of-nowhere jump back in time leaves Sans confused. Frisk had promised him that they wouldn't do that anymore. Soon, however, Sans discovered that the kid didn't really have a choice.

Sans blinked rapidly, sure something was wrong. He was on the couch in his home he shared with Tori and Papyrus and Frisk. There was a high pitched sound of a kettle boiling in the nearby kitchen. Sans could hear the voice of Tori saying; "Oh, hold on kettle, I'm coming!"

Something seemed spine-chillingly familiar about the moment.

On the TV was an episode of some show that he had never even heard of...only...he knew what was about to happen in the show, like he had watched the scene several times now. The words and background music followed a familiar pattern in his mind. He knew he had seen it before, recently too.

On top of that, he was sure he was doing something before this moment that was decisively not the thing he was doing now.

He hadn't had this feeling since he lived in the underground. That could only mean one thing.

He jumped from the couch and went upstairs to Frisk's bedroom, thoughts pounding in his head. No more jump backs in time, the kid had promised him! What...what had happened that was so bad the kid had to reload? Were they hurt? Bored? Angry? Messing with him?

When he arrived in Frisk's room, he knocked on the door softly before opening it. He was greeted by...an odd sight to say the least.

Frisk was out, fast asleep on top of their keyboard. Thier computer was on, showing that they had been busy at work typing some school report before seemingly collapsing on the 'h' key.

Unsure how to proceed, the skeleton observed the child. The kid had a troubled look on their face, their features, which should be relaxed with sleep were screwed up, twisted into a horrible frown. Their breathing, which should be sound and mellow, was hitched and unsteady. As San's approached they heard a quiet whimper.

"No." The child said, sleep heavy in their voice, still in the land of dreams, "Please, don't, don't go. I'm sorry, I can do better."

The sudden sound of the kettle and the TV startled Sans, as he found himself yet again on the couch. His memory from only a second ago was fast fading, and this time he teleported up to Frisk's bedroom, utter horror running through his bones. The kid was sleep-resetting. This was bad.

He reached the room again only to see that Frisk looked even worse than they had before. This time they were sobbing a little, "I don't want to kill." The words were slow. They were crying. "I'm so sorry...I...I…" Suddenly came a broken word, so quiet the Skeleton almost missed it. "Sans." Then even softer, "I'm sorry. Don't…"

They screamed. The child sat bolt upright, shrieking, a sound that Sans remembered from his nightmares.

He ran to comfort Frisk, wrapping them in an awkward hug half-hindered by the desk chair. "shh, shh, shh, it's okay. don't cry, it's okay." He hushed.

Frisk wasn't quite awake, but was quick to take to the comfort. They buried their head in Sans hoodie, sobbing loudly and shaking violently. "I'm sorry, I'm sorry, I'm sorry!" They sobbed.

"it's okay, it's okay, you're safe now." Sans told them. He managed to scoop the kid up and walk them over to their nearby bed. The child clung to San's hoodie, absolutely determined to keep it close to them, and Sans sighed before shrugging out of it and lending it to the kid.

Frisk curled up to the hoodie like a teddy bear, and breathed in and out, trying to settle themselves. Sans sat in the desk chair and watched over them until they came to their senses. It took about 5 minutes, which is a very long time to watch a friend in pain.

Soon Frisk calmed down lying still in their bed. Slowly they noticed that something was up, and they rolled to their side to get a better look at the room. Their eyes widened confusedly as they took in their surroundings, lingering for a second on the window, then the clock that read '12:20 pm' then Sans.

"Uh, uh, Sans?" They began, trying to compose themselves "oh my god, is that really the time? I'm so late for school!" Their voice was exhausted, but they sprung to their feet.

"whoa there kiddo," Sans put a halting hand on Frisk's shoulder, "It's a saturday, you're good to go."

"What? No, I thought...did I... Toriel let me sleep in that long?"

"nope. you reset."

Frisk blinked. "No I didn't."

"yes you did. at least twice."

"When?" They sniffed, wiping a stray tear from their eye.

"don't know the exact time, but I'm fairly sure it was well you were sleeping."

"What?!"

"you had a bad dream, and reset in your sleep."

Frisk was at a loss for words. "I never...th-that's not good. I wouldn't want to…"

"reset it all well you're out?"

Frisk nodded worriedly.

"well, then, we'll have to get through this together. i don't want that either kid." He thought for a second. A decent way to get rid of nightmare was to talk about them, come to terms with them in real life, maybe that would help. "do you want to talk about it?" He asked.

Frisk opened their mouth, then closed it, shaking their head.

If San's had lips, he'd be worriedly biting them. "alright kiddo," he began "maybe we can talk about it over a snack." He remembered the kettle downstairs, "how does tea and toast sound?"

Frisk nodded, "good." They admitted.

The two went downstairs in relative silence, Sans had retrieved his hoodie, and Frisk clung onto his hand. Soon the two found themselves at the kitchen table. Frisk sat above their tea, pouring honey into it. Sans stirred some sugar in his. They both had warm pieces of toast with jam and butter. The sweetness from the jam wafted up and made Frisk smile. Sans watched them with sad eyes.

After a second, Frisk spoke, "You know Sans," they took a bite of their toast, "I'm really glad to have you on my tea-m"

Sans gave a small laugh, "i could toast to that." They clinked mugs, and both giggled.

Maybe, together, they could get out of this jam.

Yay! Undertale fic. This one is super-cutesy, and I like it. I really like the idea of Frisk's power malfunctioning in their sleep, and I wish there were more fics with that concept. Feel free to steal that concept if you'd like. I'll probably end up editing in the morning, but for right now I think this is fine. Tell you what you think in the comments below!
