In The Hobbit book, I always find it anti-clamitc that Thorin Oakenshield somehow snaps out of his dragon sickness when the Battle of the Five Armies begins without any character development that he cause him over come his sickness.
I'm just thinking about what did the script said during Thorin's awakening from the dragon sickness like : - voices talking- (Thorin looks at the void and the void looks back kind of stare, complete zooned out)
