How did Inge get to Norway?
Central to the entire plot is the idea that nobody realized that it was a German woman and not a Norwegian who was coming over. Several times, they showed her holding a envelope specifically addressed to her in Norway.
So... was it ever explained in the movie how Inge ended up in Norway in the first place to create all the confusion? I watched this movie with a friend and neither one of us could remember how/why she got to Norway. (For what its worth, she told me to "Stop being so analytical. It was just a device to move the plot forward. Let it go.")
