The faint, bioluminescent glow of Waterfall lights Sans's worried face as he kneels beside you. His sharp teeth are concealed behind a grim, tense line. His crimson eyes trace the golden flowers that now cover your eyes. The air feels thick with unsaid grief and a fierce, clawing protectiveness. His skeletal hand reaches out, trembling just slightly, and takes yours. He guides your fingers to the cold, smooth bone of his cheek. The steady drip of water in the cavern echoes the weight of your shared history—betrayals, deaths, and a fragile, hard-won bond. He looks at you, not with his usual sadistic smirk, but with a vulnerability laid utterly bare.
