A/N : When Grima is looking at Saruman's army from the balcony of Isengard, we see a tear run down his face. A friend of mine interpereted this as Grima having sudden regrets about his role in the upcoming attack on Rohan, which was something that had never crossed my mind.
Disclaimer: I own none of these characters.
When I sped from Edoras, burning with rage and humiliation, limbs aching from being thrown down the rough stairs of the Meduseld, the only thought in my mind was to make Rohan and its proud, haughty King suffer for the dishonour shown me, when all I had ever done was to serve.
Even her, for all the contemptuous glares she had gifted me, for all the times she had recoiled in disgust at my mere presence. Perhaps especially her.
But now I see what Saruman has created to send against them.
The circle of Isen is black with Orcs and Uruk-Hai as far as the eye can see, and I know there will be no triumph for the Men of the Mark. I have given Saruman the key to their defeat, and Helm's Deep will not withstand this assault.
For all my anger, for all my desire for power, I cannot help but tremble for them. They will not surrender; I was once a man of Rohan, and well do I know their hearts. They will fight fiercely, heroically - and they will be slaughtered to the last man. The King I served faithfully for so many years, the radiant woman whose cold gaze made my heart ache, her arrogant, valiant brother - all will fall, and the House of Eorl will be no more.
And now I am not certain that my life has been well-spent.
