I was thinking earlier today about something FREAKIN' awesome of what I think should happen in LoK.
Ok here it is:

I think Korra should lose her bending by Amon.


Yes, I know that sounds really REALLY weird but, just hear me out. I was thinking that she should lose her bending, but good ol' Tenzin continues to teach her. Not Airbending at the moment but the spiritual side of bending the most important part of being the Avatar. So she conects with Aang and all her past lives and she is then able to regain her bending and the first she masters is Air. She then has to re-master the other four elements!...
