Uh he had a translator because he simply didn't want to cooperate. Elves dislike humans but respect nature. So he was being petty. But now he got over it and decided to cooperate. The translator was for the Chancellor to be able to talk without having to use or reveal he knows the empire's language.
Uh I hope I was of help

Wait so why did he have a translator if he knew the language? What was he trying to accomplish? I wasnt paying attention
