Summary
sans brings home a machine (one that’s already ruined his life more than once, by the way.) it malfunctioned, tore holes through reality, and dragged in his counterparts from places that he shouldn’t have business knowing existed.
so when the machine activates on its own once more, he heaves a sigh and slumps down, mentally kicking the bucket. nothing surprises him anymore; the machine convulses like it always does and he expects another version of him to tumble out. he gets his speech ready and—
oh. it’s a human.
