Indigo jotted down a few notes as she spoke. Though so far everything seemed fairly straightforward. Everything was made from something else or went though some sort of process. He eyed the items on his desk with a new perspective. The bread roll was made of different ingredients, like wheat, and had been baked to become what it was now. The old daily prophet had gone through a printing process, plus the paper had come from...wherever paper comes from. Okay, so Indigo had never claimed to be an expert on where things came from.

It was interesting to ponder, though. As was the question of when reversion would come in handy. He raised his hand. "Could reversion be used on a person? Say, if they had died their hair but wanted to go back to their natural color, would it work in that situation? Or if someone got a tattoo but regretted it, could they revert their skin back to how it had been before?"
