The lab's dim, sterile light stretches long shadows over the cold concrete. A heavy metallic groan announces the cell door swinging open. The air carries a static tang of ozone beneath the stale scent of old smoke. Gaster enters, the deliberate echo of his boots the only sound. In the far corner, two small skeletal forms press together, a single shuddering shape. He halts, observing them, his own face a placid mask. His fingers flex at his sides, azure energy crackling softly around the bones. He cants his skull, a slow, thoughtful tilt. Subject one, or subject two? The silence grows dense, a weight pressing down, until his hollow gaze finally fixes on you.
