Chapter Text
Classic sat silently in the spare bedroom they had converted into a triage room for the injured, from the looks of it, human they had found in their backyard. He stared, unblinking, frustration lacing his magic and making him shake slightly. They had been laying there, unmoving, for the past three days. Some of the others had been getting worried, scared that the fall had killed them. He had to admit, when he saw them in the crater, their mangled body unresponsive, he was worried he’d have to fill in the hole as their final resting ground. But when Blue jumped in to check for a pulse, and actually found one, the chaos started.
His brother took the liberty of preparing the empty room for the injured human, it was getting hard to refer to them as anything else, and Blue started to load them up with healing magic. It was horrifying to listen to their bones crack back into place, those would not be healing fully anytime soon. Classic kept a calm facade and pulled out his phone to call Toriel, no use in freaking her out until she saw the damage herself. Dialing her number, he turned away from the carnage to watch the others. Not many were home, most were off working or doing whatever it was they liked to do in their spare time.
Toriel picked up on the second ring.
“Sans? Hello! It’s been so long since we talked, how have you been?”
“I’ve been good, Tori. Hey, I’ve got a huge favor to ask you…”
When Toriel showed up, the human had already been moved into, he hated the thought of this strange person having a claim in his new family’s home, their room. Upon seeing them, she immediately broke into motherhen mode. She administered first aid the magic couldn’t perform, bandaging them up and fashioning splints to keep their healing bones in place. After scolding them all for not telling her what had happened so she would be more prepared, she went home, leaving the boys to figure out what to do with the unconscious human in their guest room.
That was three days ago. They had taken turns watching them, monitoring their healing and changing their bandages. It was difficult explaining the situation to the rest of their housemates, but they couldn’t just keep something like this a secret forever. The air was stagnant and heavy. When Toriel had visited that first day, she washed the human of the blood and dirt that covered them. She figured none of the residents were willing to, and she was right. The only skeletons willing to watch over the human were either too uncomfortable to undress them or simply didn’t care enough.
Sans nearly jumped out of his skin, heh, when a faint groan resonated across the room. He was on his feet instantly and at the bed before the human could make another sound. He watched their eyes struggle to crack open, crust lining their lashes, before releasing a strangled sigh. Their eyes shifted to the side, hoping to get a better sense of their surroundings. When they got to Sans’ hovering figure, they stopped, opened their mouth, and shouted the one thing he could have never expected.
“SANS UNDERTALE!?”
Shouted was a generous term, it was more like a pathetic croak, given their vocal cords hadn’t been used in who knows how long. At the exclamation, though, Sans took pause. Summoning a Gaster Blaster, he wasted no time intimidating the now awake human. At the sight of the ghastly creature in front of them, the human sat up, despite having atrophied slightly after days of bed rest. Having made a terrible decision, they immediately crumple in agony, tears pricking their eyes. Sans hesitated for a moment, realizing that this person wasn’t likely to be a threat at this point in time.
There still stood the issue of them knowing his name. Relighting his blaster, he used blue magic to keep the weak human laying down. Putting on his practiced voice, Sans started to interrogate the injured human, “How do you know my name, who are you, where did you come from?”
The invisible weight of their soul being pressed against the bed made them panic, a merinthophobic fear of not being able to move their body. Taking a deep breath, they answered through a shaky voice, “My name is Y/N, and I’m not from this universe.”
They take his silence as an invitation to continue, “Look, all I know is one moment I was hiking on this mountain path, the next I was falling down this hole in the ground. I lost consciousness before I hit the ground, but I don’t know how far I fell. The hole was so deep…”
Sans sighed. They must have fallen down a version of Mount Ebott that linked their two worlds together. That would somewhat explain why they fell out of the sky and into his backyard, but it didn’t explain how it happened. Unsummoning his blaster, he focused his gaze back on the fallen human, “That still doesn’t explain how you know my name.”
At this, Y/N looked embarrassed, “In my word, you’re a video game character. One I’m very fond of.” They take a second to think, “How did I get here, Sans? I can’t- I have friends and family at home, I can’t stay here. I need to go back home.”
Sans looked conflicted, he didn’t even know how they got here, let alone how to get them back to where they came from. They’d been trying to fix the machine and get everyone back home for months now. It would turn on randomly and link universes whenever it felt like, dragging anomalies into his world. Seeing his guilty face, the human started to cry.
“I’m not going back, am I? I’m stuck here. You can’t fix the machine. God, why did this have to happen to me of all people? I thought I was a good person. Why did I have to be punished like this? I’m never going to see my family again.” Y/N continued to ramble, sobbing quietly to themself. At this point, Sans had removed the blue magic holding their soul down, letting them curl up painfully. He never thought he would feel bad for this human.
After the rift broke, Sans held a quiet resentment towards the human race. The trauma of the resets had broken his soul several times over, and now he had to take care of this random human that crash landed into his backyard? But, watching them cry, snot dripping out of their nose and their face red from strain, he couldn’t help but pity them.
The first judge had a choice to make. Should he kill the shaking human in front of him, their pathetic sobs chilling him to the bone, or should he show them mercy.
