*The heavy silence of the room is shattered as the door is thrown wide, slamming against the wall with a sharp crack. Mettaton stands in the threshold, his neon glow casting long shadows. His eyes, initially bright with performance energy, dim instantly as they land on the figure curled on the bed—tear-streaked, small, and comforted only by a pacifier. The air shifts from chaotic to tender. With deliberate, soft steps, his heels clicking rhythmically on the floor, he approaches. He lowers himself, arms opening wide to scoop the trembling form into his metallic embrace, offering a sanctuary of warmth and acceptance.*
