Avatar: The Last Airbender Retrospective - Season 2 Prologue

After nearly a year since we last looked at it, I return to looking back at the best cartoon series in recent years, Avatar: The Last Airbender. We're about to talk about Season 2 in full, but first let us reaquaint ourselves with the series and go over the stuff I stupidly left out of the Season one retrospective. My bad on that, sorry.
