Oh dang this is so cool, all bending comes from animals? Dragons for fire bending, sky bison for air bending, and earth moles for earth bending? I wonder what animal water bending comes from.
The fire bending masters episode was amazing. They memorized those dance moves a little quick when they'd only just seen the statues, but I didn't even care, that was freaking badass. The way they were doing the sacred dance with the dragons flying around them and then both dragons doing the rainbow colored firespin... That was awesome.
And heck, just an episode about Zuko and Aang as allies (nay, maybe even friends) together on a mission? Book 3 is awesome. Who would have thought it would be Zuko who would teach Aang fire bending.
