Juliana has got to be the most stupid person on the planet (Spoilers)
Letting Joe Blake go despite the resistance telling her he was a Nazi spy? She must have felt stupid when they told her later he went to Berlin with the film. Just because she had feelings for him? To help an enemy agent instead of helping one's own country men?
Then..... she kills George Dixon. Granted she was shaken up from the resistance trying to kill her. But to save a kid with a terminal illness? Shot her dad's friend who helped her and her parents in the back?
Man, if everyone was as emotional as her and didn't use their brains all wars and resistance movements would be lost. She single handedly if unintentionally did more damage to the resistance than Nazi or Kempeitai.
She's basically the opposite of John Smith. If John Smith shows amazingly cunning, she's a typical emotional fool.
