Hola Essex,
Respectfully, I am not losing sleep over the Witch King vs. Gandalf situation in Return of the King, but considering that this thread is devoted to expressing views regarding that scene, I will be happy to continue to use this forum as a vehicle to share my points, and hear other points.
Also, I am not quite clear on the significance of Gandalf's having to confront Denethor, and thus needing to be devoid of his staff.
