In "The Warriors of Kyoshi" we see the debut of Suki, and get to see just how badass the titular warriors can be. In "The King of Omashu" we are introduced to Bumi and laugh the entire way. Finally, in "Imprisoned" we meet nobody of real importance to the overall story, but George Takei makes a funny guest appearance. Can't win 'em all I guess.
