Korra

Finally watched the season finale of The Legend of Korra and it was so GREAT!! but watching the show kind of makes me feel like an old person... all of my old friends are dead except for Katara... well, all that I know of anyways.. O.o but I have no idea what the second season will be about, or, if there even will be a second season... :/
Spoilers...maybe?
I was about to pass out when she went into the avatar state, "WELL IT"S ABOUT TIME!!!!!" and when Zuko's grandson (he was his grandson, right?) had the same voice as Zuko!! But I just couldn't really match his voice to that body...it just felt weird...
