Hitler and Geli scene
Near the middle of the movie, there's this scene when Hitler retires to the country with Geli, where she falls off a bike, and Hitler leads her to a field of long dried grass (?), and then asks her to run around again and again through the grass. Hitler seems to derive enjoyment from this, and Geli distress (to the point of being in tears).
What is Geli supposed to be doing, and why is Hitler enjoying himself? Is there a deeper significance to that scene? I'm confused.
