The prince walks up behind her, and places a hand on each shoulder.  "My Captain, you have not failed.  You valiantly stood your ground, and I have no doubt you would have killed the intruder or died bravely as you intended.  However, as prince I must look beyond the obvious, and look out for my soldiers.  Had you been victorious, you would have hated yourself for killing someone who was trying to save a friend.  Had you failed...I would have been forced to replace you...and that is something you mustn't make me do."
