Looks like a few minor changes in the storyline have been made, consolidation of characters. I don't remember Elrond being around in THE TWO TOWERS, but rather his 2 sons. No biggie, tho.
And a voice was heard out of the night that answered him, as if from far away:
"To fulfil our oath and have peace."
Then Aragorn said: "The hour is come at last.
Now I go to Pelargir upon Anduin, and ye shall come after me.
And when all this land is clean of the servants of Sauron, I will hold the oath fulfilled, and ye shall have peace and depart for ever.
For I am Elessar, Isildur's heir of Gondor."
I'm going to be mighty disappointed if we don't hear those words, and see the Ride of the Dead....
To Aragorn I was bidden to say this:
Where now are the Dúnedain, Elessar, Elessar?
Why do thy kinsfolk wander afar?
Near is the hour when the Lost should come forth,
And the Grey Company ride from the North.
But dark is the path appointed for thee:
The Dead watch the road that leads to the Sea.
