Pass-the Drill | [s2e13] (12-13)the Serpent's

"The Serpent's Pass" and "The Drill" serve as a pivotal double-feature in Avatar: The Last Airbender , shifting the narrative from wilderness survival to the direct defense of Ba Sing Se against a massive Fire Nation siege engine. Sokka’s strategic infiltration allows the team to sabotage the drill from within, culminating in Aang's decisive battle against Azula and marking a significant victory for the Gaang.
