Nothin' wrong with a little singin' to keep your chin up, son. But far as I know, ya can't go home just yet. Uh, not until you learn Bending, I think it was. Ya see, this city's not just a city, it's a magic city, run by someone named Nautilus.

But don't you worry! When ya go back, you'll pick back up right where you left off, as if you were never gone to begin with!
