Okay, Eragon, I repeat ERAGON, is the one who is seriously injured, NOT Saphira. This one scene completely ruined the possiblity for a sequel. The first half of Eldest, Eragon struggles with his injury. Then the dragons heal him, turning him into a half elf/half human breed. Most of the events in the rest of Eldest and most of Brisingr are only possible because Eragon has the physical characteristics of an elf. Also, during this scene, Eragon should not be battling Durza while on Saphira, but in the main chamber of Tronjheim without Saphira, Then Arya and Saphira break Isidar Mithrim to save Eragon. That provides a story line for Brisingr because Saphira restores Isidar Mithrim to it's former glory.
