S2E19 The Guru

Aang makes his way to the Eastern Air Temple seeking wisdom from Guru Pathik, while Sokka finally comes face to face with his father, whom he thought he’d lost forever. At the same time, Azula is plotting a sinister scheme against her foes in the Earth Kingdom, targeting both Zuko and Iroh in her ruthless plans.
