You cannot give a specific name to your Pretender, as everyone else will see it, and they would probably complain. The same goes for the Prophet, though the idea about the scout is nice enough. Next time, switch renaming off.
Note, however, that naming your scout "Entente Cordiale" is unlikely to work: anyone from England would likely get the meaning of the name, and both entente and cordial can be used in English. Naming your scouts "Auld" should work better though... but it is not good enough. You should just look up examples appropriate to the history of the receiver, slightly alter the name, and that ought to work well... perhaps too well though.
