When Two Worlds Collide. (Sans x Reader)

Chapter 2

Chapter two's out! I'm posting this really early as I have more chapters on the way. It's longer this time so enjoy~

Sans woke in a start to a tremendous crash. He leapt out of bed, eye flaring up as magic rushed throughout his body, heightening every sense. When he was scared or threatened, this tended to happen, thanks to doctor W.D. Gaster's experiments on him as a child. He shuddered, ignoring his past and trying to calm his almost animalistic magic. It was probably lightening hitting the roof, he assumed, hardly convincing himself.

All of a sudden, a scent flooded over him. This wasn't rare as he often found himself smelling things unnaturally well when his magic swarmed his senses however, this time, he smelt something he couldn't explain. Usually, he could match scents to people, whatever they are and, occasionally, even match them up to faces.

This smell confused him. He took deep breaths, distinguishing what he could. Sweat and rainwater, okay they'd been perhaps running in the storm? A sharp, tangy smell reached him. Hmm, blood, a lot of it too. Not sure 'bout that, he thought, reaching for the flashlight by his bedside table. He sniffed again. Female, young?, he couldn't tell through the other scents.

He followed the scent out into the apartment stairs. Sniff, up, follow. Up, follow. Up. The smell appeared to be coming from the roof. He could hear the wind crashing into the door and the rain hammering down and he was tempted to turn back, yet the smell was so strong. He had to help.

He pulled his hood up and pushed with all his might against the door and wind. The door gave way and he stumbled up the final step into the raging storm. The wind howled around him, slamming the door tight behind him. It was jammed. No biggie, he could teleport after all. He turned back around and scanned the roof for any damage. His sharp eyes latched onto the vague outline of a figure, lying on their side. Sans cautiously circled the form, seeing who or what it was. It was a person... with wings.

Sans stopped in confusion, before rushing towards them. Yep, definitely female. His magic was starting to wear off and exhaustion crept in, but he had to get this girl out of the rain and into his apartment.

He scooped her up and teleported into his bedroom. She was soaked and her armour looked heavy, at this rate she'd catch hypothermia for sure. By the looks of it, she was knocked out cold. He had no choice but to undress her and lend her some clothes.

Sans wrapped her in a warm towel and placed her on his bed as she was still freezing even though he'd dressed her in a baggy white t-shirt and some loose shorts. Now he'd calmed down, he had time to properly examine the mysterious girl who'd suddenly appeared on the roof.

Her thick black hair was wet, knotted and tangled with thorns, as if she'd hit one of the bramble thickets that dominated the roof, and she had small, lean, horns poking out from the top of her head. Her face was petite and beautiful yet her build was as strong as Undyne's.

Sans had to cut out two holes stretching almost to the bottom of his t-shirt to fit her beautiful, jet black, wings so they wouldn't be tucked up, and another on his shorts as her long cat like, also black, tail. He should ask Undyne if he could borrow a hairbrush tomorrow.

That was when he spotted the charred hole in her left wing. It was it was a gaping wound, a couple of inches across and raging red. It had obviously been burnt, he could tell due to the scorch marks and how sealed it was. Only intense heat could do that. Sans wondered what happened to the unfortunate girl.

He shook himself back to sense. He had to disinfect the injury or it was at high risk of getting infected, and that would be a lot more difficult to look after then. Sans was pretty sure that he had a first aid kit in the kitchen. Luckily, although he insisted that he didn't need it, the apartment owners had been firm and supplied one anyway. He was damn glad of it now.

He stumbled over to the kitchen, kicking away some ketchup bottles on the way. His drinking habit had gotten out of hand ever since Paps moved in with Toriel, Asgore and Frisk because he couldn't support his own brother. To him, ketchup had the same effect as human alcohol, whenever he drank a bottle or two, he'd get incredibly tipsy and his thoughts would get fogged over so he couldn't think straight. Papyrus had always used to keep Sans in check.

He reached his tiny kitchen and began searching the cupboards for the green first aid kit. After a minute of searching, he finally found it and began to make his way back to where the girl lay. She was still knocked out so Sans decided to just go ahead and treat her anyway.

It took him a good hour but in the end, he figured out what to do and was pretty proud of himself at his bandaging job. First, he'd cleaned it, applied some burn cream to the wound, then dressed it neatly, making sure it was tight and secure. All he could do now was wait.
