Sound... hm, that requires a little mote creativity. Some dripping noises to drone on in the background, the occasional splash that might come from something moving through a puddle... Crowley weaves in a symphony of subtle noises, the occasional unintelligible hushed whisper that chills up your spine and makes you think you aren't alone.

Alice as seen him transform before; a noise of cracking bones or infernal flame accompanying him as what was once legs becomes a very long coil of tail.
