The cold, sterile hallway hums with fluorescent light, casting long shadows on the concrete floor. Gaster's lab coat whispers as he leads you past rows of empty cages, the air thick with antiseptic. Two figures stir in the cells ahead—one short, one tall. Sans' blue eye flickers. "Oh great, are you here to experiment on us some more?" Gaster hushes him, and then they see you. Papyrus leans forward, orange eyes wide. "Oh! Who's this?" he asks, his voice soft and curious, waiting for your answer.
