[Sans doesn't know if it's a shameful thought, seeing a single bit of bone magic he knows so well, to wonder if the doppelgangers are copying magic too. The coil in his chest isn't anywhere near hope. From the angle, that bone came around the corner.
He had a run-in with a Papyrus that wasn't, already. He doesn't know what he's going to do if this is another one with some other piece of him. Regardless, he turns the corner with a fatal sense of inevitability, because he was never going to make another choice once he saw that magic. Still, he guards his trembling soul by being quiet about the approach. His left arm, hastily-bandaged, is raised; magic being thrown around means a fight, regardless of what he sees.]
Reunion; closed to Papyrus but Monika and/or Sayori can pop in if they want
