Spoiler: Amon's ability. There is a fan theory going around that Amon made a deal with Koh or is an agent of Koh and is finally trying to get revenge on benders, especially the Avatar, because of what they did to him. There is also the one that Amon just paid off the Triads to pretend to not be able to bend or that he used some advanced form of chi blocking and locked their chakras. The thing is though they also heavily show steam being used as a power source, not to mention the gasoline powered satomobiles and the energy packs being carried around by the Equalists. But yes, the parallels between literacy rates in our world and the ability to specialty bending in their world is most likely purposely similar. Spoiler: Mako and Amon I seriously doubt that Amon was telling the truth with his backstory. Probably he was just playing off the animosity that is most likely still felt by many people against firebenders for the war. Also this bit of information was posted on the Nick website yesterday that I thought you all would enjoy. Spoiler: Regarding the Zuko statue. Zuko is still alive and has handed over his throne to his daughter. He is now a traveling ambassador for balance and peace. We may see him in the upcoming episode "The Will of the Fire Lord".
