In Peter Jackson's The Lord of the Rings: The Two Towers, after Théoden exiles him, Grima Wormtongue takes refuge with Saruman. Saruman is shown creating a large explosive device, and then Saruman and Grima go out onto one of Orthanc's balconies to survey Saruman's army of 10,000+ Uruk-hai.
After Saruman says, "To war!", a single tear rolls down the left side of Grima's face as he looks over the army of Uruk-hai.
Why was Grima crying?
I know this isn't addressed in the movie itself, but would like to know if it's addressed in any of the LOTR special features or in the book The Two Towers.
I'm wondering if Grima had second thoughts about betraying Rohan when he saw the Uruk-hai? Or if he thinking of Éowyn and what he believes to be her imminent doom? I did research this question, and while it's been asked before, the majority of answers that came up were either from 2003, before the extended editions and special features were released, or the essays were no longer at the URL that was cached.
