Who is the green dragon rider in Eragon?

arya duh.

Yo pal I agree with you that it wiil be Arya. Many say that it will be Roran because he shares Eragon's blood. I also thought so first but then if Roran becomes the rider then what will happen of poor Katrina who is a mortal human unlike immortal riders and elves.

Also green fits with Arya's personality because of the elf-nature love thingy.
