Sans had been about a few months into his world travels, something he had put off for far too long and needed far too much, but never one to miss a call from home, he was surprised to see his phone flashing at him after he had stepped out briefly.
Wondering slightly why anyone would call so late, surely being on the other side of the world meant you only would receive phone calls at this time if it were something highly important, wouldn't you?
Cautiously he returned the call, letting out a sigh of relief when his brothers overly loud voice filled his ear. "SANS! I WAS WAITING FOR YOU TO CALL BACK!"
"Hey bro. Sorry I missed your call, was outta the room cuz-"
"SANS, Sans, B-Brother... You have to come home. Right away. The human, Frisk she's, been in a accident... I don't-" barely registering his brothers change in tone, the first few words sent something akin to lightning shooting threw Sans's skull.
Sans never tried teleporting a distance as far as he did, but if Frisk needed him he would have drained all his magic to cross an ocean in the blink of an eye.
Crackling blue magic filled the room as Sans appeared right in the middle of the kitchen and startling Papyrus into drooping the phone.
His brother had immediately began his breathless rapid fire explanation of Frisk's predicament, and for once Sans was grateful his brother didn't pick up the breathing habit he did. He had jumped too far too quickly, not even building up his magic before his eyes were blazing. Now he was gripping the edge of the counter as the kitchen swam in front of him, his brother a blur of white and blue and noise. Papyrus was attempting to give him all the information he needed as he dashed around the house, grabbing his Keyes and scarf along the way. Sans, unsteadily following, was quite, his worrying gnawing a hole in his metaphorical stomach as Papyrus's words and actions grew more and more frantic. He was trying very hard to concentrate on his brothers words, but he was struggling. The strain of teleporting and this indescribable feeling that was pressing on his throat were making clear thoughts near impossible. With black spots dotting his vision, Sans so desperately wanted to ask the most important of questions, when can he see Frisk?
Finally feeling enough will to reach out and grab his brother after he dropped his keyes again with shaking hands, Sans locked eyes with his nervous expression.
"How long ago did it happen? Which-Where's the hospital, we need to go- now Pap, we need-" San's words came in a rush of nerves and worry, his brother grasping his slumping form, only now noticing his condition as Sans legs gave out from under him.
"BROTHER- YOU DIDN'T- YOUR MAGIC! SANS?!"
Sans felt the cold tile and his brothers magic nervously flutter around him, but the black spots had grown in his vision and he couldn't tell if his eyes were open or closed at that point.
With a dull thud, Sans skull hit the floor, all light drained from his eyes.
Some knight in shining armor you are, buddy.
He fell into unconscious as Papyrus alternated between shaking him and dialing Undyne.
Authors note: WOW it has been forever since I wrote a fic hasn't it? Sorry this is so short, getting the layout right. Fortunately this lovely little game has reignited my passion, and oh am I in love with Sans (and Papyrus, so adorable.) Please let me know what you think, I have some ideas for this one, and I'm planning a looong one. Will eventually be Frisk/Sans, with a little Undyne/Alphys and Papyrus/Mettaton for flavoring. Set after the barrier is broken, true pacifist run. -Jaz
