Tony slowed as he approached the light, sneaking on his toes and squinting down the hall as the considered his repertoire and couldn't think of a single good thing that wouldn't cast a light and alert Bruce to his presence. He would have to get a good one off on the first try, and maybe-- ah, Tony knew what he had to do. Hugging the wall, he let his wand drop out of his sleeve and brought it up to whisper, "Melofors," so gently that the spell seemed to drift down the corridor and settle over Bruce's head like a veil. When it did finally flash orange, Bruce couldn't possibly have time to react, his head encased in a pumpkin instantly. Now Tony's reign of terror could last as long as it took Bruce to escape.
