From this episode of soul searching, Korra is going to realize that the limitations of being the Avatar and the limited assistance of the Air Nation to bring global stability will not excuse her from what she was born to do. You cannot runaway from your problems because they will eventually get the better of you. Everyone is going to have to endure internal struggles sometime in their life . Korra was never given a choice before and now that it seems like she can continue on her own, she is going to have to deal with Kuvira sooner or later. All I can say is there is going to be a war in the Earth Kingdom. A lot of people are going to die. A character (perhaps more than one) we have grown fond of since the beginning of the show is going to perish. But in the end, as always, the Avatar will be the trump card in finishing the fight and bringing balance to the world.

It's clear why Nick doesn't air this on TV anymore…this was never a kid show nor was it meant to be.
