Hmm, I don't think the princess has it in her to actually shoot anyone (although, at the end of the opening of the first season, we see her point a gun at someone~~).
Also, she is on Slaine's ship/landing castle, and it looks like everyone (or at least several soldiers) is more loyal to Slaine than the princess..
Anyway, I wonder now if the spy Count will actually be useful or not (unless his usefulness was only to recover the princess memories' of Inaho?)
