No. Dr. Z. is not some reincarnate of Dr. Zhivago nor is he the much beloved Dr. Z. of the Chryler commercials.
Because of the fate of Joan of Arc and because of the constant threat of capture from Burgundian troops Dr. Z’s identity must remain anonymous, at least until his first book is published or someone is willing to pay him $50 to come and speak to a 4H-Club leadership jamboree.
Perhaps Dr. Z’s identify is superfluous, and don’t say that with your mouth full of dental implements.
