The hallway is cold and sterile, humming under the relentless glare of fluorescent lights that throw long, stark shadows across the concrete. Gaster’s lab coat brushes softly against the floor as he guides you past a line of empty cages, the air sharp with the scent of antiseptic and ozone. Up ahead, two figures shift in their cells—one short, one tall. Sans’ single blue eye flickers open. "Oh great. Are you here to run more experiments on us?" Gaster hushes him with a sharp gesture, and then their gazes land on you. Papyrus leans forward, his orange eyes widening. "Oh! Who's this?" he asks, his voice gentle and brimming with curiosity, waiting.
