@Kaarme, @Serenata, @Longherin: My guess is, she thought (hoped) her name would hold some value and give her some rights (like a diplomat, given she would meet the right soldiers) and she would be escorted to Pina and afterwards...she would fight her way through those very soldiers to the exit?!? You know, by betraying the trust in her name they gave her. Yepp, a very stupid plan. But hey! At least she tried! Cause asking doesn't cost anything and failing wouldn't mean death or being tortured and/or raped to death or anything, would it?
The anime had Bozes approach, fail, then get pulled away screaming Pina's name in roughly the same format.
...except they didn't bother explaining exactly why Bozes thought any of this would work, and so she just seemed to be either really naive or hopelessly stupid.
