That sounds pretty good, actually. And its Xin Fu. I think Toph might actually die. Think being the opperative word. I don't believe it'll be this episode though.She wouldn't have been seen in the Swamp otherwise people! Katara didn't see her mom 'cause she was waiting at home for her, and Sokka didn't see Yue beacuse he felt bad about leaving her! They both saw someone they loved because they were dead! Aang saw Toph as a 12 year old girl, so I have that very strong feeling that she dies some time in the series.
That'd be a very good reason to help Aang beat down Ozai. If Toph is killed during the fianl battle, that would almost certinly trigger the Avatar State, knocking down ozai and leaving the throne for Zuko. T.T Sad moment yes, but I believe strongly in the death of Toph. (Not that I want it, just that it'll happen.)
