Avatar Season 2 Episode 4 Review: Ba Sing Se's Darkest Secrets Come to Light

The walls of Ba Sing Se are supposed to keep the danger out, but in Avatar: The Last Airbender Season 2 Episode 4, titled "The Water Falls, the Stones Emerge," the show drops its busiest, most jam-packed hour yet. By aggressively smashing together legendary storylines from the animated source material, including major pieces of the beloved "Tales of Ba Sing Se" and the random introduction of a world-weary Fire Nation defector, the narrative attempts a massive balancing act. It is a lot to digest, but the sheer volume of secret identities and political drama keeps things highly entertaining.

The episode kicks off with Aang trapped in the ultimate bad vibe. On one hand, Toph is dragging him out of bed at the crack of dawn for some brutally uncompromising earthbending lessons. Her training style is completely unyielding, forcing Aang to confront the rigid philosophy of the element by basically telling him to stop being so soft. On the other hand, the ever-smiling Long Feng is playing the ultimate fake bestie, giving Aang a VIP tour of the lower rings and introducing him to local townsfolk. Long Feng’s sudden friendliness is obviously a trap. He is purposefully keeping the Avatar distracted and comfortable so the kid stays entirely blind to the aggressive political censorship rotting the core of the Earth Kingdom capital.

While Aang is busy being naive, Sokka is playing detective because he noticed that their inventor friend, Sai, vanished into thin air. Sokka repeatedly leaves notes under the door of the empty workshop, only to realize the city is actively swallowing up anyone who asks the wrong questions. A local scholar named Zei confirms the grim truth, noting that students, teachers, and anyone with an opinion are regularly disappearing under Long Feng's creepy regime. Meanwhile, Toph gets cornered by a blackmailer named Lau Wong, who has the receipts showing her high-society parents are secretly profiting from the Fire Nation war machine. To bury the scandal, Toph makes a quiet, mysterious transaction. The emotional fallout leads to a striking argument between Sokka and Toph entirely framed in haiku poetry, a brilliant, creative nod to the classic animated format that anchors their growing friendship.

The absolute peak of the hour shifts to the Lower Ring, where a community of Fire Nation defectors is targeted by Jet, who is still consumed by unyielding hatred and plans a violent raid on the refugee camp. This sets the stage for a spectacular nocturnal clash where Katara slips into the shadows to protect the citizens, fully embracing her role as the Painted Lady. Right beside her, Zuko dons his infamous mask from the first season, choosing to fight for people he owes absolutely nothing to as the Blue Spirit. The two vigilantes stand side-by-side to repel Jet’s gang, completely unaware of each other's true identities in a sequence that feels like pure fan fiction in the best way. The fight peaks when Katara freezes Jet to a wall, but in his anger, Jet yells out her name, inadvertently exposing her identity to a stunned Blue Spirit.

Out in the wilderness, Princess Azula, Mai, and Ty Lee ambush the Kyoshi Warriors. Fed up with Fire Lord Ozai delaying her military campaign, Azula takes matters into her own hands. The trio steals the armor of the elite warriors, using a captured commander as a prop to effortlessly bypass the outer walls of Ba Sing Se. The infiltration is complete, the bad guys are wearing matching outfits, and the stage is set for a massive political collapse.
