The promise

It had been a few years since Sans had renounced his own genius. After that, he resigned himself to guard duty alongside his brother so that he could always spend time with him. He made some puzzles here and there, ate at Grillby's, and generally napped throughout the day. 

The small skeleton stretched his arms up in his bed. He had just woken up from his mid-morning nap. He considered going to Grillby's but he knew there wouldn't be many people there right now. He thought for a moment and smiled. He decided to go visit his friend from beyond the door. 

The snow beneath his slipper clad feet crunched against the sound of the peaceful winter breeze. He passed by Papyrus's guard post but it was empty. "he must be with his puzzles" Sans said calmly. 

Sans made his way down a snowy path towards the border of Snowdin. The rocks watched him as he made his way to a dark corridor. Mushrooms lit the dark path leading to his favorite spot, a large door bearing the delta rune.

He sat down, his back against the door. He lifted his hand and slowly knocked twice on the door. Silence greeted him.  The skeleton sat there for a little while and closed his eyes. "Hm, it doesn't usually take this long" he thought. 

Knock. Knock.

Sans opened his eyes. "who's there?" he asked.

"Dishes", the voice answered.

"dishes who?"

"Dishes a very bad joke" A snicker followed behind the mysterious females joke.

Sans sat there and giggled. He and this voice began exchanging jokes about a year or so ago. He had come across this door when he started exploring the underground more, after he quit his job. He had knocked on the door several times when he ventured this way. Then one day, he got a response. From then on, he and the voice became friends.

"why did the cyclops close his school?" Sans asked.

"Why?" the snickering voice asked.

"because he only had one pupil". Both he and the voice laughed.

They exchanged jokes for quite some time. Sans couldn't believe he found another bad joke enthusiast. He uses some of them for his own material too. It was tough for him to change his personality from rigid scientist to relaxed comic, but he figured bad jokes were a good way to start. 

"What do you call an alligator in a vest?" asked the voice.

"what?" Sans asked between snickers.

"An investigator!" she exclaimed. They both cracked up laughing. After a while, they both calmed down and sat there in silence.

"Hey..." the voice started.

"what's up?" Sans asked.

"I know this is a bit much....and it's probably a bit much to ask..." she paused. "But...if a human ever comes through...would you promise to protect them for me? Protect them until the end of their journey?". 

Sans didn't know what to say. He wasn't one to keep up with current events, but he knew that the king was looking for them. He heard the others at Grillby's talking about it, how Asgore was going to free the monsters with the power of human souls. He thought for a moment and sighed. 

"How could I say no to a fellow joke enthusiast?"

"Thank you..." the voice replied. You could hear the relief in her voice. "Thank you so much..."
