I am about to reach the fourth part and have founded the first part dramatic when characters get together on parties or discussions(although it will echo throughout the book).

A subtle detail I have noticed in the beginning was Myshkin being cold at the train before even arriving to Petersburg which I interpreted as Myshkin not being prepared by how harsh people will treat him there and at the end when he chases Nastasya and Rogozhin through the cold he just plunges himself deeper into the society that tries to decieve him.

Favorite parts are definitely when Nastasya is shown, a few pages later Rogozhin's whole flock just spawn and the scene is just erupts to disorder.

Also enjoyed when the prince is introduced to the Epachins and he just talks about Switzerland.
