I’m having feelings about Katara v Pakku again, and the fact that at this point in the series, Katara has never been in a fight that wasn’t to the death. Every fight she’s ever been in has had world-ending stakes. She’s not shooting to kill Pakku because she’s weaker and less trained than him - though she is - she’s shooting to kill because she doesn’t know any other way to fight. Friendly sparring, or fighting as a spectator sport, has not been a part of this girl’s life. Pakku’s fighting Katara to put troublesome teenagers in their place; Katara’s fighting Pakku because they’ll all die if Pakku doesn’t pull his head out of his ass and train the Avatar.

Pakku is genuinely surprised to see his own reflection in that disc of ice Katara shoots right past his face. If he hadn’t dodged, it would have sliced his head right open. He starts putting actual effort in after that.
