19XX - YEARS AGO

It was cold but not windy, and Sans was, honest to The Angel, very grateful for that.

His plans for the evening were very simple, just spending time with his little brother and make up for time lost, even if he knew it didn't exactly work like that. It hadn't been that long and Papyrus seemed to be okay, or so he told himself. He had missed him, missed this easy interaction that didn't end with him shivering or doubting himself. Papyrus was so great.

Being honest with himself, though, he was a little worried. It had been three days away without going back and who knew how much time would be next time he got stuck in the Labs for one reason or another? Because, there would be one. If Sans knew something, it was that. As much as he tried, he would be held up in the Labs, loose the sense of time passing, forget to eat and sleep and go home.

His hand tightened subconsciously. It was harder than expected to make himself relax, but he didn't want Papyrus to notice anything wrong. At least, not today.

No, today was a day for the two of them and no one else.

Sans looked at his little brother. It was cold, that much was true, but just walking side by side with the other skeleton, sharing laughs and funny memories in fondness...

It filled him with warmth.

"Hey, Sans?" Asked Papyrus, cutely tilting his head to one side at the same time that he looked to his big brother, his eye-lights manifested. It reminded Sans of the puppy eyes Greater Dog would use to get something from his parents. "Can I ask you a question?"

With a loving smile, he nodded to the little skeleton. "Of course, Paps. What is it?"

For a moment, Papyrus only observed Sans, searching for something. Honesty, perhaps? Sans wasn't sure if he passed or not, but he tried to put the thought of his little brother studying him like Gaster would observe one of his experiments out of his mind. Apparently, Papyrus found what he was looking for, a confident face appearing on his features.

"Where is Gaster?"

Sans' smile froze.

They got to their final destination relatively quickly. It was just a field full of ice and snow puffs, a sentry station just ahead in the path that was currently empty. Was it Furray's? He wasn't sure.

They passed Greater and Lesser Dog in their way, playing in the snow. A detour wouldn't hurt and, besides, Papyrus seemed to be having fun. His little brother ended up playing fetch with the dog monsters, Sans himself throwing the branches from nearby trees. Big brother's privileges.

Hearing Paps having a good time, making friends with Lesser and Greater...

For being trapped in the Underground, Sans never felt so free.

It had been a good day. He had laughed, had some good food and spent time with his little brother. He sighed, a sense of contentment and relief flooding his senses. He had been worried for nothing, it seemed. Papyrus was his usual ball of energy, impossible to keep up with. Man, his little brother was so cool.

The evening had passed without further incident. They didn't have time to make a snowmonster this time, but just the NiceCream and the company seemed to be enough for the little one. Relieved, Sans smiled, letting the warm environment relax him even further, almost falling asleep in the living room table.

They had been eating quietly (or as quietly as they managed with Papyrus happily eating and chatting) in Grillby's house, not allowed to be in the bar at this hour. Though that expression was lost on Sans, considering their lack of sunlight or moonlight. Was it day or night? Was it late or soon?

Grillby had prepared them a few burgers and milkshakes. Usually, the hunger from all the day's activities would catch up with Papyrus and he would cave in, eating the greasy food, as he told him one day. Today, obviously, that hadn't happened.

When Grillby asked Papyrus after his day, Papyrus excitedly told him all about how Sans had gone to pick him up and go play, eating NiceCream before dinner.

Busted.

He found he couldn't really mind, even if the weary sigh Grillby let out of his mouth was very present in his mind. The fire monster looked exhausted but the indulgent smile on his face relaxed the skeleton quite a bit. He didn't know what he would do without Grillbz and, honestly, he didn't want to find out.

"Hey G. So... How was work today?" Face unreadable, the scientist just stared back.

"Sans, mind telling me why is there spaghetti sauce in the wall?" The skeleton looked everywhere but at the older monster, nervous. Gaster let out a weary sigh, looking exhausted. "I'm going to the basement to work. Do not disturb me."

Ashamed, Sans lowered his head, wishing the ground to swallow him whole.

"And I expect that to be clean when I get back."

A lonely blue tear fell.

But Grillbz wasn't like that. He had proved himself, time and time again, no matter what shenanigans the skeleton brothers pulled. He was a constant, almays with a warn hug and a soft smile ready.

Grillbz was amazing.

Cheerful thoughts, Sans told himself. That's right. Cheerful thoughts.

He had to stay positive. He had been doing so well today, too. Maybe he should do this more often. That thought seemed impossible enough to sour his mood just a bit further, knowing perfectly fine that the next day he had a lot of work to make up for today so Gaster wouldn't notice anything amiss. Tomorrow seemed so far away, though...

Sans relaxed again, even more than before. He would deal with that tomorrow, that wasn't his problem at the moment. He let himself enjoy and laugh and be filled with warmth once more. He heard his brother laugh at something silly and his smile broadened. That would be future Sans' problem. Here and now, he just focused all his attention on his little brother.

He didn't see it, didn't notice anything different, but Grillby let a sigh of relief at seeing the furniture stop shaking. This was going to be a problem soon.

Grillby kept silent.

The next day, when Sans had to go back to the Labs in the morning, he found himself a little bit lighter than the day before. Paps would be okay and Sans asked Greater to keep an eye on his little brother, just in case.

Sans was filled with happiness.

And that's it. Sorry if it's a bit short? I'm not entirely sure about this chapter.

Next: the story continues. Something important does actually happen? Yes, it does. Finally XD.

If you read "Oh, The Angel" or similar expressions, it's because in Deltarune there is supposed to be a religion or something about the prophecy? So, I just switch expressions we use like "Oh, God" or something like that with its counterpart? I guess?

So, what are your thoughts? Reviews and constructive criticism are always welcome. Remember English is not my first language, so if you see a mistake somewhere just tell me and I'll try to fix it.

NellB out!
