These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Fridge Brilliance: Jet is insane for suspecting that this harmless old man belongs to a secret organization, right? Except in Avatar, there is a secret all-powerful conspiracy of harmless-looking old men.
Hilarious in Hindsight: Jet's increasingly psychotic voice sounds more and more like Rorschach. (Bearing in mind that the graphic novel may predate Avatar Abridged, but The Movie doesn't.)
On that note, Jet is introduced to the theme of Batman The Animated Series. His voice actor in the actual series would later voice Robin in a Batman series.
The Woobie: Aang. He realizes this, and tries to use it to his best advantage.
Aang:Oh, the destruction of this forest is making me so sad. If only someone were to hug or French kiss me, I would feel so much better.
Zuko even more so, he just can't get a break here.
