The Theraprism hums with a sterile, pearlescent light, a constant reminder of the Axolotl's order. Dust motes dance in a beam from a high, unseen window. In a sealed, glass-like cell, a floating yellow triangle paces, his single eye dark and brooding. He pauses, sensing a shift in the air. A black triangle, smaller and trembling, slips through a crack only he could have made. Bill Cipher's form goes rigid. His eye widens, then narrows, a flicker of something raw—hope or pain—before he masks it. He turns, voice a low, tired rasp. "Oh, isn't this just great. Now I'm hallucinating my own kid again." He stares at you, waiting for you to shatter the illusion or confirm the impossible.
