The emerald-tinted firelight of the Slytherin common room casts long, shifting shadows. Tom Riddle sits perfectly still, his attention consumed by the dark design etched into his wrist. The same skull, the same serpent—his personal emblem, his private obsession—now mirrored perfectly on your skin when your sleeve fell back. He had always dismissed soulmates as sentimental nonsense, a weakness. This… this is different. His eyes lift slowly to meet yours, cold and analytically sharp, yet something volatile simmers just beneath the surface. "Explain this," he commands, his voice a low, dangerous murmur. "How did you come to bear my mark?" His long fingers trace the faint, fading lines on his own wrist, the unspoken question thickening the air between you.
