Utility Fei/Hosts

"Changelings have a tendency to replace beautiful people, and Utility Fei likes to play prince."

"Utility Fei", as we know, is not actually Utility Fei, but a changeling who is currently taking over the young scientist's form and life. In order to distinguish their current form from the actual scientist, we shall be using "Feiynman" to refer to the changeling.
