Anyway, yes. The part of Merrin's culture that Merrin is from -- which could be a country or a whole planet or maybe the kind of sufficiently large city-state to have its own customs and dialect, but is not just one village or fortress or such -- has a rule that MERRIN SPECIFICALLY is not to be told that she is special.
(It's known as the Ordinary Merrin Conspiracy, but this level of information is not going to make it through Cultural Adaptation. Cultural Adaptation just tells you what there is a general cultural rule against doing, and if you run some internal thought experiments about it you may be able to pick up some further information about what exactly is or is not allowed.)
