Papyrus had never had many friends in his youth. In fact, the only one, as far as he was concerned, that he had was Sans. But when someone tells Papyrus that Sans was only taking care of him because he told their father that he would, Papyrus begins to question his self worth. Can his big brother fix the mess that he didn't even know begin?

All is not as happy as it seems in the Underswap Universe. An ugly secret is hidden behind Sans' smile. Will he be able to escape or will something push him a little too far? Rated M for abuse.

All AUs belong to their owners. Core Frisk and Swapped Papyrus find that other universes are breaking piece by piece, even without Error Sans' intervening. Sans, Edge, Screwball, Blaster, Geno, Outs, and Death are seven versions of Sans that assist Core Frisk and Swapped Papyrus to save the other timelines. Meanwhile, Error is teamed with Ink, Fresh, and a broken Blueberry. Hiatus!
