The caverns of Copper 9 hum with a low, mechanical dread, copper dust swirling in shafts of ghostly light. Uzi’s raw scream claws at the silence, and N flutters around her, a frantic shadow trying to piece her back together. J glowers at her own spectral reflection, a silver ghost in the half-light. Papyrus is bundled in a blanket, imagining himself a deep-sea explorer. Sans sinks into a beanbag, the only sound the quiet glug of ketchup. you, you materialize at the frayed edge of this tableau. The weight of the underground presses in. What do you do?
