S3E2 Rebirth

Tenzin, Jinora, and Team Avatar head towards Ba Sing Se in search of new airbenders. Along their journey, they visit several villages, hoping to recruit individuals to help restore the Air Nation. Unfortunately, their efforts yield minimal results, with only a young boy named Kai agreeing to join them. Meanwhile, Zaheer traverses the four nations to liberate his fellow inmates from captivity. After rescuing Ghazan and Ming-Hua, they aim for the Northern Water Tribe to free their last comrade, P'Li. Upon discovering their escape, Lord Zuko sets off for the Northern Water Tribe to thwart their plans.
