Boy, I'm totally hyped up about this episode. I dunno but I have a pretty good feeling that this might be anice episode just like The Crossroads of Destiny, Sokka's Master, The Winter Solistic, The Blue Spirit and The Day of the Black Sun. I have also heard rumors of Chapter 14 of Book3 titled The White Lotus. Things seem to get pretty interesting. I'll just have to take the suspense on like a man lol.
