Suppose two countries have different languages and none of the them know each others language remotely. They send one person from each country and they learn each others language and after a while the kings of both countries meet with the translators to talk to each other.
King1: Hi, My name is King1. I welcome you on behalf of my country.
Translator for King2: I have informed the assasins to kill this Translator for King1 the moment he moves or makes a sound. We are almost ready to attack the city.
King2: Very good. They have no idea and now they can;t be informed of the danger.
Question: Now what should Translator for King1 do?
