Sans just stared. He didn't have a good reason to care. Walking up the stairs, he decided to go clean his room like Papyrus had suggested. Cleaning his room was a good way to think about things, and with Frisk intruding in on their life, Sans really needed a chance to form an opinion.

The thought that Frisk could have been snuggling in his bed if his room had been cleaner kept circling in his mind. It was stuck on repeat along with questions of why he had cared about the human. It seemed like the cleaning was almost working to well. That was part of why he didn't want to clean often, memories of things that used to exist taunting him. Sans didn't even notice his questions on Gaster, the strange thoughts that kept trying to resurface, this time. He had more important things to worry about, like if he actually cared for the Frisk. He hadn't tried overly hard to catch her and had let her go, but that was because he thought that having a human actually do his puzzles would make Papyrus happy. He had let her hide, but Sans had felt sorry for her with how afraid she had gotten when Toriel had attacked her, and Sans didn't want that to be her first impression of Papyrus. Why had he intervened in the fight? That was simple. Sans had seen how terrified Frisk was of Toriel. If she had been more aware, Frisk would probably have found a way to dust Toriel, that was how terrified Frisk had been of her. Sans didn't want that to happen to Papyrus! Still, her knowing Wingdings was frightening. The odd feeling when she had held his hand before… Sans started blushing lightly at the memory as he picked up that sock idly.

The feeling itself wasn't entirely knew. Sans had wondered about another monster from time to time. It had never come to anything, and Sans had never been this interested in the feeling. Still, Frisk was a kid, and one that he had only known a day, at that! There was know way that anything was starting between them right now. Trying to ignore the implied later, Sans thought of other things that would make him care for Frisk. She had been tolerant of his jokes. She didn't really join in, but she didn't make a big deal about them one way or another. She had been willing to go along with his scheme to cheer up Papyrus. That was really nice, even if Frisk was nowhere close to liking Papyrus nor vise versa. Sans decided that he would reserve his judgement about that for until he had seen more of her behavior firsthand.

Reaching for another sock, Sans was brought back to reality. There were no more socks under the bed. There wasn't any more trash either, all of that was neatly tucked in the tornado. The dirty clothes were all on his bed now, waiting to be taken downstairs. Shrugging, Sans answered their call. It wasn't like he had something better to do. He might shock Papyrus by happening to pass him in the hall on the way to the washing machine. It would be actually doing the laundry the way he said he would, but that wasn't enough to stop Sans from finishing his task. The cloths were easily dumped in the washer, the soap was added, the lid went back on, he hit start, and now there really was nothing left to do.

Hearing a yawn, Sans went down to see if Frisk was awake. Seeing her still drowsy, he tucked the blanket back around her. "Go back to sleep kid. You can rest as long as you want to"

"But" Frisk started, turning in her sleep.

"Just rest" Sans said, draping the blanket back around her again. She calmed down at that, starting to snuggle a little closer. Sans wondered what to do now. Hearing Papyrus slam the door as he left, Sans knew that he couldn't pin the human off on his brother. Still, Sans had sentry duty to. Checking the girl's temperature lightly with the back of his hand, he decided that she didn't really have hypothermia. She was far too warm to the touch. She might be starting to catch a fever. but that seemed to be the worst of it. Deciding that fevers weren't fatal, Sans wrote her a note and left it on the coffee table. It would draw suspicion on him if he wasn't at his guard post, even if he spent the time snoozing himself. That would be that safest thing to do for Frisk.

Frisk woke up slowly. She was on a sofa of some sort. Wiggling her legs, she was covered by a blanket. Sitting up, Frisk took in the world around her. The sofa was green, a cozy faded color. The walls looked pale as bone. There was a coffee table and a note. Reading it, the note explained what she was doing here.

"Frisk

You're at my house. Papyrus thought that you were getting sick, so he brought you over here to rest. I heard that your throat is getting better, so at least you have that. If you feel up to it, Papyrus left some spaghetti in the fridge. I don't think that he'll be mad if you eat it, not when I've admitted that I don't enjoy it. Have as much as you want, even though you'd have a hard time reaching the burners and shouldn't try. Go ahead and explore the house, there aren't any skeletons in our closets, not unless you count Dad. Ha, got you there, didn't I. Seriously though, go through anything you want to, but don't go outside. Could be dangerous.

Sans"

Feeling hungry, Frisk immediately went after the spaghetti. It was just as tasty as before, creamy and goey. Frisk even risked heating it up herself again, just to take that again. She thoroughly enjoyed it.
