The Legend of Korra - Book 2: Spirits

 Spoiler

Tumblr just pointed out a VERY, VERY interesting fact.

After Ravaa, the one who was holding all of the elements, is ripped out of Korra, she's not a water bender. She's an airbender. Thoughts? Rewatching the last episode, and she does in fact use Airbending at 6:36, when jumping into the tree of life with Tenzin before she goes all blue-giant.

 Spoiler

Her spirit purified vaatu with waterbending. It is as it was said above, she could still bend everything.

Although...this is kind of a weird flow switch. Last season we were dealing with the fear of not being able to bend to now knowing we can bend not one but all the elements even without the thing that made you "the avatar".

Also what's the point of the avatar state now? It was to remember the experience of past lives. She has no past lives.
