I hope he has a grand/son in Legend of Korra. And he still gets tormented by the Avatar. That’d be great. WHAT IF HIS GRAND/SON IS AMON?!? AMON IS HOLDING A GRUDGE FROM HIS GRAND/FATHER AGAINST THE AVATAR AND BENDERS IN GENERAL BECAUSE OF THE TROUBLE AANG AND THE GAANG CAUSED AND SO HE STARTED THE EQUALIST MOVEMENT. YUP. THAT’S TOTALLY IT.
